How to choose a charger for the battery. How and what to choose a charger for a car battery

Rechargeable battery is an important element of any car, requiring care and timely service. During the ride, the battery is charged from the generator, but it does not always happen enough for its normal operation. Short trips around the city, strong frosts, connecting powerful energy consumers - all this can lead to the fact that the car does not start the car.

Starting device

The charging current of the device is indicated in the range, for example, from 6 to 12 A, or from 15 to 40 A. The higher the maximum value, the more current You can serve when charging, therefore, the charge will be replenished faster. It is recommended to operate according to the following algorithm: the current of the charging current should be 0.05 - 0.1% of the battery tank. Suppose you need to charge the battery at 77 a · h. Simple calculation is made: 77x0.05 \u003d 3.85 (a). So, the acb of such a container should be charged with a current.

Additional functions

The simplest starting devices for controlling operation provides signal LEDs. Charging and trusk-charging devices of the traditional type have an arrow or digital indicator to monitor the charging current. It is not necessary automatic, since the process does not require control - only LEDs can be on the panel, for example, connecting to the power grid.

Stand By mode supports the operability of the car system in the absence of a battery. It will be useful if there are many sensitive electronics in the car.

Boost mode charges the battery in accelerated mode on high current. Will help B. emergency situationWhen you need to urgently recharge the battery before traveling. Timer - addition to the Boost function - is needed to select the accelerated charging time. After the process is completed, the current is stopped automatically.

Pulse charging In automatic type devices allows you to maintain a full battery charge for several months. It will be useful when storing the battery when the car is not used. You can not even remove the battery and do not turn it off from the on-board network.

Desulfating - mode in pulse devices, which implies work with a current in pulse mode to reduce the risk of sulfates on the battery lead plates. It will help to extend the life of lead-acid battles.

Memory function saves charge cycle settings when the electricity is temporary shutdown. After resuming, its filing continues the process with the same parameters and from the same stage, on which the charging was interrupted.

Stir protection will be useful for all batteries. It provides for presence fusewhich triggers when closing or improperly connecting the terminals to the battery. Protects from breakdowns both the device itself and the battery.

Reference article based on the author's expert opinion.

Each car owner sooner or later faces the inability to make the car due to the fact that the battery sat down. According to the "law of meanness", this often occurs when the car is most needed.

Tell how to choose a charger for car batteryTo protect yourself from such situations.

Risk factors

Accumulator battery ( AKB) It does not sit just like that. It is believed that new car With the new battery is able to work without replacing or recharging the energy source of the onboard network up to three years.

But this is a conditional period, it all depends on the quality of the battery, from the used light sources in the headlights ( lEDs are much more economical incandescent lamps), from a ride style, from the conditions in which the machine is operated - in the cold, any battery is prone to a self-discharge, finally, from the forgetfulness of the driver, many forget to turn off the music overnight parking lights etc.

Finally, no one is insured from generator failureIn this case, you can drive a couple of kilometers on one acb, but after that it will discharge in "zero".

Charging the automotive battery is possible both in the car service and at home. Optimally have a special charger at a personal disposal ( Zause).

How to choose the correct battery charger? Video:

Select the charger for the main parameters

The main selection criterion is the output current parameters. They must correlate with the parameters of the AKB. Thus, in modern motorcycle and vehicles, excluding specialized, use batteries with output voltage from 6 V at motorcycles to 24 V trucks. The vast majority of passenger cars, including diesel, has a battery on 12 V.

Accordingly, the onboard source of the energy of the truck must post 25 V, a motorcycle - 7 V. This is a necessary safety margin.

The memory is chosen according to the class of your car.

The second important parameter is the output power and the charging current. Each battery has a container expressed in amps-hours - 55 A / h, 65 A / h, etc. Each car is suitable only by the native type of battery, on the power of which it is designed. The memory must issue charging Tokexactly the corresponding power of your battery. The maximum threshold is calculated as 10% of the current output strength in amperes.

This means that for charging the battery at 65 A / h, the maximum current at the output should be 6.5 A, the optimal one - half of this value, an example 3.2-3.3 A. Charging the maximum current is not recommended, since she leads to accelerated battery output.

Note that professional charger can have a wide range of output current settings for strength and voltage - from 6 to 24 in the appropriate power. This allows you to charge cars of cars of different classes, but also it is more expensive.

Select battery charger

In addition, it is necessary to take into account the design of your battery. At the moment, different types of batteries are present on the market:

  • lead;
  • lithium-ion;
  • nickel-cadmium;
  • gel and others.

They differ some operational characteristics. In particular, the most unpretentious of all - habitual lead, the most demanding of the charging conditions - nickel-cadmium, they necessarily require a three-time circuit-discharge cycle for reliable operation. If you have such a battery, then you will have to pick up the memory specifically for it.

Gel and lithium-ion batteries also require the use of chargers that support work with them. Information on the types of service served is in the instructions for the charger.

How to choose the best charger for automotive batteries?

This is the main question for a conventional car owner who is not a worker of auto service. For most people most importantly - simplicity and safety of use, preferably the correspondence of the technique "pressed the button and forgot". It corresponds only to the automatic charger for the car battery.

Most of these devices refers to a pulse type. The pulsed charger for the car battery is charged with small pulses, without the participation of a person, adjusting the output current parameters.

There are three main ways to charge any battery:

  1. constant voltage;
  2. constant current;
  3. complex, or smart mode.

The optimal charging mode of the battery is charging a constant voltage. The fastest - constant current, but with such a way the battery may suffer.

In lead, for example, the plate sulfate begins, they are coated with sulfate sulfate sulfate.

As the charge accumulates, the supplied power must be smoothly reduced - only the intelligent charger for the car battery is coping with this. It automatically adjusts the current parameters at the output, not allowing reloading, and when reaching full charge It turns off on your own.

If you need to maintain a permanent charge of the battery, without using it for a long time as appointment ( for example, as a backup), T. you can leave it connected to automatic memory for the whole winter.. It will turn on and off itself as needed by supporting the specified charge level.

Another important function - the ability to start the engine at a completely sex battery. Putting charging devices possess it.

They are able to issue a single powerful impulse that can scroll through the starter and start the car. Start-charging devices are equipped with their own battery, so heavy and cumbersome.

Another important feature is the presence of emergency recharging mode, sometimes it is called Boost. They have some memory without a direct start-up option. This charging mode is a powerful constant current, it allows you to "pump up" the battery in a few minutes, but at the same time contributes to the impact of its failure and is not suitable for all types of batteries. It is not recommended to use it without emergency.

Choice rules

In order to decide which a memory you need, you should estimate it required functionality and compliance with the criterion of price / quality.

It all depends on how many cars you have and are there among them, for example, a truck with a 24 V truck; Is it worth the car in winter in a warm garage or on the street, you are mostly in the city, often drowning engine ( the worst option for any battery) Or on the highway, where the battery is constantly charging from the generator.

Some car owners prefer to regulate the charging process on their own, they are suitable for manual adjustment of the parameters.

Usually, such memory are supplied with a discrete or analog ammeter and voltmeter, have venneers for accurate alignment and refer to the class of professional. All of them have options automatic and manual operation.

Their price varies from 2,000 to 10 000 rubles. Basically, the price is affected by the brand, European and American devices are always more expensive, Chinese and domestic cheaper. In this case, the functionality of them is approximately the same: protection against reloading, random cords, overheating, etc. In most, there is protection and short-circuit.

As a memory with manual adjustment The charge can be considered, for example, the model "AutoElectrician T-1021". It has two modes of operation, while manual provides more accurate battery charging. The range of output containers is very wide: from 3 to 90 a / h, output voltage - 12 V.

The device works from the network, has a built-in flashlight. The advantage of it is the price - about 2000 rubles with a fairly rich functionality, it provides a full range of protection measures, including the restoration of the discharged lead battery with sulfated plates. The disadvantage can be read by the lack of boost mode and the direct engine start.

How to charge automotive battery charger at home or in the car?

There is nothing complicated in this. Most of the modern stumps do not require the mandatory disconnection of the battery from the borough system of the car.

Basic rules for charging automotive batteries Consist only that the process should occur in a warm dry place ( houses, in the garage or on the covered parking lot), Battery terminals must be clean, without oxides, the battery itself is proper. Electrolyte hollows on AKB are not allowed!

Connecting clamps to terminals is carried out as follows: plus the memory to the plus of the battery, minus to minus. The first always connects the positive wire, according to tradition it is red. Then minus, he is black. Next, the device is included in the network. The mode of operation is carried out according to the instructions.

Turns off B. B. reverse order: First dealers, then removed the minus black wire, and only then the plus red. Observe these simple rulesAnd the electrician will serve you for a long time faithfully.

Each car owner must take care of the uninterrupted, the most important component of electrical equipment, without which the engine start does not seem possible. The failure of the battery as a result of the discharge is quite frequent phenomenon, especially in wintertherefore the issue of acquiring funds restoring functionality rechargeable batteryEspecially relevant for cold regions.

The battery does not produce electricity, it only accumulates it, and then gives. The battery is charged from the electric generator of the car, but the full charge is not achieved at the same time, so after some time the battery loses its charge, requiring the connection of external devices. With a plus temperature, the engine is able to start and from half a charged battery, but in winter the chances of starting are significantly reduced if the battery charge is incomplete. Experienced motorists know how important it is to always have a saving remedy for the sudden discharge of AKB.

The car market offers countless all sorts of charging devices of different quality and cost, but the choice of the device must be approached with full responsibility. It should be considered the fact that not every charging can approach the battery of your car, so it is important to know which type of battery the machine is equipped. To navigate among the variety of species and manufacturers will help the rating of chargers for automotive batteries of 2019. It contains devices with different characteristics in the wide price range of domestic and foreign production.

Types of Charger for AKB

Among the range of car batteries, you can find instances with additional options. In addition to the main function, they can perform many others, but the cost in this case will be the procedure higher, so before buying you need to decide which additions will be really used and whether overpayments are worth it.

Charging and starting devices for acb are:

  1. Pulse. The advantages of adaptations of this species are compactness and small weight as well. They are more convenient to use, higher in cost than transformer charges, but later the acquisition justifies itself. The principle of operation of impulse devices is based on the creation of currents high frequencyFor which large dimensions are without need.
  2. Transformer devices are much more comprehensive and constantly to have such a device is inconvenient, usually they are used for stationary battery maintenance. The device action is to reduce the voltage by standard conversion. Transformer chargers are considered reliable, easily repaired, but have a lot of weight.

When choosing the best charger for a car battery, you should carefully examine the characteristics of the instruments, weighing all the advantages and disadvantages. In addition, you need to pay attention to the type and parameters of the battery, this information is contained in the passport of the vehicle.

Top 10 inverter memory

Under the inverter (pulsed) charging devices understand car chargingproviding the restoration of the capacity of the battery in full automatic mode. This feature provides an intelligent microcontroller, which can analyze all the most important parameters of the charged battery and, depending on these indicators, select the desired ampero and voltage on their own time. From the user, it is not required to enter or change the device in the process of operation of its settings, while the inverter memory provides the most gentle charge conditions for the battery, which prolongs its resource. Distinctive feature Such devices are high functionality provided by a large number of pre-customizable parameters, as well as a high level of security. The main advantage of inverter devices can be called the protection of the battery from the recharge, which some types of auto accumulators do not like.

Korean zoom can be called unconditional rating leader in terms of price and charging quality. The best pulse type charger for the automotive battery in its category provides 9 modes of operation:

  • testing the battery for its condition and correctness of the connection;
  • desulfation;
  • soft recharging for highly discharged acb;
  • the main mode, providing up to 80% of the battery charge;
  • the absorption function when charging is carried out when constant voltage dynamically reduced current;
  • recovery function is used when charging highly discharged batteries when the electrolyte bundle;
  • analysis of the battery on the ability to hold the charge;
  • full recharging (using minimum currents);
  • the "pulse" function ensures that the maximum battery voltage in storage mode is maintained.

The device has protection against cakes, overheating, reloading and KZ.

There is a system of protection: from cakes, overheating (reloading) and short circuit. Additional advantage is three year old factory guarantee. Able to work including with solemolt batteries.

In addition to the available cost (about 2.0-2.1 thousand rubles), it is characterized by high functionality, including the ability to memorize settings.

The only disadvantage can be called manual switching Between the 6/12 V modes, the model cannot distinguish the nominal voltage of the battery.

Second place in the 2019 rating of the best chargers for car batteries occupies a professional model from the Swedish manufacturer. CTEK MXS 25 pulse charging can only work with 12-volt batteries, but it supports batteries in a very large range of containers (40-500 AH) at a maximum level of charge current 25 A.

Despite such impressive parameters, the device has low weight (less than 2 kg.) And (235x65x130 mm.). Able to work with all types of lead-acid batteries (WET, MF), as well as with gel and agm batteries.

MXS 25, as the previous model, is a multifunctional apparatus with support for 8 modes, including - Supply, which allows you to use the memory as a power source and disconnect the battery with the basic settings.

Among important functions, it is worth noting the possibility of diagnosing the battery for the subject of the ability to receive a charge, as well as to hold it, the possibility of desulfation of plates, detailed prevention of AKB.

Advantages of CTEK MXS 25:

  • the powerful charger can be used for all types of batteries;
  • full automation of the work of the memory in all modes of operation;
  • five-year warranty from the manufacturer;
  • the presence of the Supply function that allows you to save the settings after turning off the battery;
  • high level of security (from moisture, mechanical damage, sparking, strokes, shortcuts, voltage drops, rearness).

Unfortunately, there is a drawback - quite high cost CTEK MXS 25 (about 35 thousand rubles).

The third place in the ranking of the best impulse chargers is another representative of the South Korean concern. This intelligent device has good set Functions and features high quality assembly. It can be used to recharge both six and twelve-told batteries, that is, it is a universal model.

The DW450 uses a microprocessor own development (Upgraded ADC 12 Bit), which is able to estimate the state of the car battery and based on this analysis, adjust the charging parameters, voltage and current strength, which optimizes the charging process and extends the battery life.

Works with all types of lead-acid auto accumulators (WET / MF / GEL / AGM) with a capacity of 40-120 Ah.

Other advantages of the model:

  • the presence of an informative digital display displaying the charging process in real time:
  • diagnostic function;
  • "Winter" package that allows you to exercise at low temperatures;
  • protection against reversing, short circuit, overheating, reloading;
  • budget value (from 2200 rubles).

Unfortunately, there is no function of desulfation of plates, and one year warranty from the manufacturer is not too much.

The product collected in Germany, by definition, can not be substantial.

So if you are interested in which charger for the auto accumulator is better, and the cost factor is given a secondary role - we advise you to pay attention to this model. It costs about three times more expensive than Korean analogues, and this can be called the only significant disadvantage of the model.

AW05-1208 - Universal memory for which there is no difference, the battery of which type and which container is charged (within 10-160 AH). True, scendic acb does not support, but in all other a device is really good: able to charge slowly / quickly, to test the connected battery and restore strongly discharged and sulfated batteries with a stratic electrolyte. There is a charge support mode: if you leave somewhere for a long time and do not want to allow the battery to be discharged - leave the recharge included.

The advantages of the model:

  • automatic determination of the parameters of the battery (type, charge values, the ability to hold it) and select charging mode;
  • excellent build quality and components;
  • and network, and interface cables are located on one side of the device, which does not cause inconvenience in work;
  • the package includes a hook, with which you can hinder the wall.

The product of a famous Italian firm closed the top 5 rating of automatic memory for car batteries. Despite belonging to the average price segment, this model managed to take a fairly high place thanks to the support of the acb of any types and high current charge. With STAR SM150, you can recharge the batteries with a capacity up to 225 Ah, that is, even those that are used in freight vehicleoh.

Such charging devices are a frequent guest of companies with a considerable TC Park, they can be attributed to the category of semi-professional. Possessing relatively small dimensions and modern designThe automotive recharging has an extensive functionality, allowing you to reanimate the hopeless battery and operate under reduced temperatures.

The device independently determines the operation modes depending on the battery parameters using the intelligent microprocessor with integrated current and voltage sensors.

Note that Deca Star SM150 is produced at the factory in San Marino, which guarantees high build quality, and compliance. All steps of charging are displayed using LED indication, the lack of display can be called the main disadvantage of STAR SM150 (as the lack of supporting 6-volt batteries).

This reliable universal memory combines accessible cost and European quality. The Latvian model opens the second half of the top 10 pulse recharging for automotive batteries. The only model in this review, providing for charging 24-volt auto accumulators, which allows the use of Vitals 2415DDDCA to recharge the AKB of both cars and cargo vehicles. Charging current can be selected manually, and switching within 3-15 A smoothly. There is an opportunity to simultaneously charge two 12 volt batteries connected by sequential scheme (relevant for heavy trucks equipped with two batteries). The intelligent microprocessor provides battery testing, the choice of optimal mode, monitoring the indicators and completing recharging with the automatic disconnection of the device.

Metal shockproof housing will protect the memory from mechanical damage, availability forced ventilation Excludes the overheating of the device.

Vitals 2415DDCA fully complies with the standards of quality, safety and protection standards, is able to restore the capacity of deeply discharged batteries.

Among the disadvantages it is worth noting the bulky building and the lack of ability to recharge old acb.

The name of the brand clearly indicates the high quality of the assembly, reliability and reliability of the recharge, while simultaneously associated with the high cost of this brand's technique. In this case, the cost cannot be called very high (6200-6500 rubles), but this is caused by a relatively low level of charging current (maximum value - 7 A). However, it is enough to recharging the majority of cars of passenger cars.

Bosch C7's best car chargers are among the high level of safety and a large resource. The intelligent microcontroller supports the three modes of operation modes, which significantly expands the scope of its use (you can recharge the portable refrigerator, run the process of regeneration of old AKB). I can work with batteries of all types, including gel. It has compact sizes and quite large functionality.

Another budget memory. So if you think that excellent quality and low cost - The concepts are incompatible, this model will significantly reduce the level of your skepticism. At a cost of about 4500 rubles, this device has impressive characteristics and extensive functionality - and what else is needed to successfully promote the market?

The result was not forced to wait: In 2016, Einhell CC-BC 10M was recognized in Germany the best in the nomination "Choice of the Year". Unfortunately, the popularity of the model is so high that everyone becomes more problematic in domestic automata.

Compact sizes and bright, stylish and fashionable design only add points to this high-quality device. The built-in controller on microprocessors Most of the operations performs in fully automatic mode, from determining the type of battery before turning off the device when 100% charge is achieved.

CC-BC 10M has all sought-after functions from restoring highly discharged auto accumulators to the cold weather package. There is also a continuous charging function that allows you to leave the battery in the garage at an arbitrarily connected to the zoom, without fear of recharging.

Among the advantages of the model, it is possible to name the presence of an informative liquid crystal display, a convenient handle for carrying or using the device in a suspended state, the switch of 6/12 V. modes

The only substantial minus is the absence of desulfation of plates.

For average cost About 4200 rubles This model can be considered one of the most accessible in our review, so the inclusion of it in the list of the best automatic memory for automotive batteries is not at all by chance.

The device is able to recharge the battery through the cigarette lighter, without requiring direct connection (but only if the cigarette lighter is connected directly to the battery, bypassing the generator circuit).

Other distinctive characteristic The charger is to use the PulseTronic branded system that implements completely automatic work The instrument and allows you to implement the following functions:

  • full protection of all electronic contours;
  • unscake protection against cakes and KZ;
  • strict control of the process of recharging;
  • reduced heating AKB;
  • increased auto accumulator operation time.

The usual recharging mode is supplemented with an accelerated (BOOST), it is possible to switch to two batteries trucks cars. It is possible to choose one of the three modes of operation T-CHARGE 12.

The model is able to restore the charge of too much discharged batteries.

The shortcoming model can be called a small charge current (5 A) and the support of the battery capacity of no more than 70 AH.

CTEK MXS 5.0.

The Swedish company is the only one who honored the inclusion in the ranking of the best car charging two different models.

What helped MXS 5.0, standing by 12 thousand rubles, entry into our top 10 pulse zoom? Possessing compact dimensionsThis recharging can restore even highly discharged acb. Swedes, as you know, are obsessed with safety, so in this device implemented all levels of protection, including the protection of the electronic component of the car. That's why this model prefer owners of expensive foreign cars - they may not be afraid of the exit of their system on-board computer and other electronic components during the recharging of the battery.

The microprocessor inverter provides 8 modes of operation of the device, and the build quality is so high that the manufacturer provides on its products a five-year warranty.

The only drawback, except for the high price, can be called the absence of a digital display.

Top 5 transformer memory

The main difference between classical transformer recharging from inverter analogues - the absence of a microcontroller. In other words, the process of restoring the capacity of the ACB is not automatically. This means that the car owner must follow the ammeter readings to stop the process as it is completed. Transformer devices may have a voltage charge regulator, while all of them are characterized by high weight and dimensions, due to the use of a transformer current converter. Despite a number of flaws described above, this type of recharging is still very popular. The reason is simple - low cost, simplicity and reliability of the design, high maintainability.

The rating of 2019 charger transformer type for car batteries is headed by Italian origin, very popular in the old world. The charge current of this model, as can be seen from the name, is 16 A, which is enough to recharging the battery capacity of 20-200 AH. With a weight of 4.5 kg. And decent dimensions of the deck are very easy to maintain and unpretentious in operation. And although the charge mode must be installed manually, it is easy, it is not necessary to be afraid of the battery reloading, since the device is equipped with appropriate protection. You can charge passenger cars, SUVs, minibuses and trucks, and it is possible to connect two paired 12-volt batteries.

Of the disadvantages it is worth noting the small cable length - 2 meters for heavy device often lacks.

In our rating of transformer memory for automotive batteries, this is the only model with the possibility of charging the battery in the usual and accelerated (Boost) modes and startup power aggregate With a fully planted battery.

To ensure such an opportunity, the device must be large and powerful. WDK START620 - just like this: at a charge current 90 and it provides a starting current with a facecliner 560 A and peak - 620 A. The unit is able to charge the batteries of almost any capacity (up to 1000 AH), and this is a record indicator for our review.

Of course, the weight of the corresponding is about 29 kg, there is the possibility of connecting two 12-volt batteries. The high level of protection allows not to worry about incorrect connection, as well as about the risk of reloading AKB.

In addition to high weight (WeiderKraft WDK START620 is difficult to attribute to mobile charger), the device is characterized by a rather high cost (from 13 thousand rubles), but it can be restored by the capacity of any, most powerful lead-acid batteries.

The only Chinese zoom caught in the ranking of battery chargers - agree, in our time it is rare. However, we cannot say anything bad about this device, and Forte itself belongs to enough famous manufacturers. The combination of fiscal value (2,200 rubles) with good functionality is the guarantee of the popularity of CB-15FP. In principle, it knows everything that is required from recharging this type: There is a standard charging and boost mode, it is possible to connect paired batteries from trucks, there is protection against recharge.

Maximum battery capacity for recharging - 135 AH. The charging current is adjustable in the range of 3.5-7.0 A. The facial side of the device is made of impact-resistant plastic, the case is metallic. Modern design, control is simple and intuitive. You can monitor the recharging process using a built-in ammeter.

The weight of the model is relatively small for transformer type - 5 kg., There is a convenient rubberized handle for carrying. The assembly is not bad, but it clearly does not reach European standards.

Taiwanese brand Garvin is well known to the Russian consumer. The company specializes in the manufacture of an extensive range of power tools, including chargers. The CHARGE GE-CB220 model is a strong middling. At the cost of about 8000 rubles, the device is able to restore the capacity of lead-acid batteries, including paired 24-volt. There is a regular and accelerated mode, the latter provides 2-3 times a faster recharging, but it is not recommended to use it for fully discharged auto accumulators. He is adapted for Russian conditions (can work with frosts up to -40 ° C).

There is protection against overload, overheating and KZ, housing - shockproof and wear-resistant. The model is worthy to be presented in the ranking of charger for car AccountsAnd if it were not high cost, the place would be higher.

Elitech UZ 20/12.

The only domestic model in our review, and not the cheapest one. At a cost of 3,600 rubles, it provides charging of lead-acid auto accumulators with a capacity of 90-180 Ah, including 24-volt battle trucks. Current charge can take two values \u200b\u200b- 7 or 12 A. Weighs just over 7 kg, which for this class Chargers are quite acceptable. The housing is wear-resistant, the design is modern, to control the process of recharging there is a built-in ammeter. There is protection against overheating and short circuits.

But we believe that it is better to pay extra and acquire an inverter model with which you will not have any unnecessary concerns - turned on and gone. In addition, the choice of such devices is much wider. Transformer models gradually, but inevitably disappear from the counters of automata.

Any car battery needs to be recharged - this is a kind of axiom! After starting the engine loss engine, the car generator fills, but not always! For example, in " cold launch"When the temperature is overboard with extremely low -20, - 30 degrees. The battery is cooled and it cannot normally take energy, it needs to be warm up, and if you move to short distances, it turns out the "subwoofer" of your battery. As a result, a decrease in capacity may develop. In general, once a month (and maybe more often) you need to recharge the battery and clear what you need a charger! But how to choose it? After all, batteries are different technologies? This article will detailed guide, as well as the video at the end. It is definitely useful, so read - we look ...


Of course, now batteries stepped very strongly, if you do not take AGM, GEL and EFB technologyEven the usual batteries are divided into three main subspecies - these are antimunct, calcium and hybrid (described in detail these technologies in the article -). If "antimony", this beast on our shelves is quite rare, because he is hopelessly outdated, then here is calcium and hybrid are very widely pressed on our shelves. And for each battery you need the correct charger, because I will say "Calcium" many manufacturers are recommended to charge the currents at 16 - 16.5V ,. And this is already as you understand completely different "chargers"!

Classic charge

I already have an article about it, you can. But if briefly, then:

  • The battery is desirable to charge 10% of its container. For example, 60 hour, you need to charge 6 ampere.
  • It is necessary to take into account the voltage of your battery, come for both 12 and 24 volts
  • Voltage should be exhibited - to go charge! I will explain. On the 12th volt version you need to serve 13.2 - 14V (it is so much the generator gives) if the charge will go from 12.7 - 12.8V, then the battery will not be charged, or it will be very slow
  • Sparing charge mode. Personally, I always recommend charging in the so-called "gentle mode", it is about 3-4% of the tank. That is, if 60 hour, we put about 2 - 3a and charge until the charging current is dropped until 0,5

This instruction is suitable for most types of battery, but not for everyone. Therefore, if you choose a charger that with a maximum voltage of 14.5V, then modern options It will not be able to power.

Pulse or transformer

Now there are only two types of "charging":

  • Transformer
  • Pulse

Transformer is outdated models that are based (as clear from the title) on the "Trazifors". They are bulky, heavy and now practically not produced. The advantages of these models can be called reliability and fault tolerance.

Impulse models are much easier and more compact, and most importantly they are cheaper, now they just flooded the market. With the development of technologies, they also became fairly stable and fault tolerance.

We look at your battery

Accordingly, we proceed from your tasks, that is, if you use old batteries, there may also be antiques, then for them almost every charger is suitable. But if you have a "calcium" or the more "charger" must be absolutely different, more perfect.

For example, the "antimony" option - if it will be added to it more than 14.2V, it will boil, and very intense.

Also calcium acb, charge the current above 16B, not each device can give it.

A large plus will be the desulfation system, if you can restore the battery (if it is still possible).

I want to note that the more perfect charger, the more options it can charge or even restore.

Charger and commissioning device

When choosing it is worth noting that there are two types of aggregates on the market for quite a long time:

  • Ordinary charging systems - they are tritely charged batteries.
  • Start-charging systems - they not only fill the charge, but they can start the car with a completely "milk" battery.

Many people might think that the usual "charger" can also run the car - but it is not so! They do not have high start currents, and trite can burn. After all, when the car is launched, it briefly consumes hundreds of amps, for example, the average for passenger carsThis is about - 300 amps, and in the winter it is possible even more. It is such a current and can give a commissioning device.

Automatic, not automatic

For me personally, a qualitative charger is, this is in which I can "handics" control "from and to". For example, voltage, current strength, charge time, etc. However, there are many, so-called "automata" (automatic charging devices) on the market. Usually chinese production, with dubious quality. Actually no designations on them, not a volotate, not an ampera - just connected and it "machine" should charge your battery! Must, but not obliged! Also from where to know what type of battery is connected to it? Yes, trite you can not even control what the tension on the terminals is now!

Of course, such options are a lot of help for beginners who do not understand anything at all in such systems! It turns out how at a cell phone, connected the terminals and forgot, there is some rationality in it. However, if you take such systems, then take serious firms, at least such as Bosch.

As I already wrote from above, I personally follow the controlled option. I love to set currents and tension yourself, set algorithms (by the way, all serious "chargers" are now programmed). For example, for calcium acb, you need so-called "swings" - if you extend when a current is a few minutes one, with one voltage, but the next few minutes another, with another voltage. Cheap "automata" by default are not capable.

Therefore, if you have thought of taking a "charging", I personally advise you to take you with the possibility of manual setting, and now they have excellent instructions in which even the "kettle" will figure it out.

Desulfation mode

This is a really useful mode. From hot weather, or from deep discharges on the plates can form sulfate sulfuric acid, while the electrolyte density will fall. These sulfates seal the plates and the battery container significantly drops. Sometimes loss of tank can be at 70 - 80%! With such indicators, the car engine cannot be launched.

Remove these sulfates is quite difficult ,. However, there are such devices that make it in regular mode, charge cycles - discharge. Just put your battery, and it costs a few hours, but most likely days. Sulfates are broken, the surface of the plates becomes clean, the container is restored. It should be noted very useful mode.

Checking the performance of AKB

Many batteries so to speak are maintenance free, they cannot be opened (without surgery) and really can not understand when one of the cans came out. It happens it tritely crumbled. If you are unscrewed in the serviceable battery and the dark electrolyte can be seen, then it is impossible to do so. Although the tension will fall to 10 - 10.5V. So modern chargers can determine the closed bank and state the "verdict", as useful function.

Measurement and control of battery capacity

Again, not all chargers, but only the most advanced, can show the battery capacity. Moreover, both the residual and the one they take. Very useful feature. That is, you can clearly see how much your battery took, how much amper for what time.

As a result

So let's run by the main steps when choosing a charger for a car:

  • 12 or 24 volts. Often if you have passenger car, Enough and 12 volt system.
  • The machine is not an automatic. Personally, I advise manually customizable unit, preferably with programs
  • Charger or commissioning device. If you have your garage, the start-charger will not be superfluous. It will run the engine of your car, even if the battery is not at all. However, it is worth such an aggregate almost twice as expensive
  • The possibility of charging AGM, GEL and calcium batteries. On many modern "chargers" such information will be indicated. This is a useful feature. Because the battery is now developing. Often, this means the supply of voltage from 15 to 16.5 volt
  • Presence of desulfation regime
  • Checking performance
  • Check capacity
  • Programmable charge. It will be useful if you can program the charge cycle, that is, one current and voltage is now fed, after a few minutes another, etc.

Actually these are all functions, I specifically did not point to manufacturers because there are really a lot of them, even on our Russian market There are very good devices, such as "Orion Vympel"(They are very flexible programmed). Also, many ask me whether it is possible to charge ImaxB6. Car batteries? Of course you can, this device is generally universal. The main thing is to choose the right power supply and set the correct program.

Charger for a car battery, judging by the full and expanded name, we will not be able to confuse with the charger for the mobile phone. Now it remains for small - to figure it out if it is necessary at all, and how to choose the charger for the car battery.

Types of batteries for a car

We anticipate the reasonable question of the car owner, and for what the charging on the battery, if there is a generator. Right. Generator is. But by connecting additional load On the on-board network we forget that the generator recharged does not cope and then additional energy is taken from the battery. This leads to its gradual discharge.

And further. It happens that we forget to turn off overnight, or on weekends, dimensions or autoacoustics. And on Monday, the car is no longer started. It happened to many. So in this case, you will need a charger for the battery.

Knowledge of information on existing types of batteries will allow you to navigate the question of what kind of charger for the car battery you choose.

  • Lead Akb - It is acidic. Very good, these batteries refer to a systematic recapture. They are recommended to charge more often.
  • Alkaline Akb - Nickel - cadmium (Ni-CD), nickel - metalhydride (NI-MH) and lithium - ionic (Li-ON). The most unsuccessful of them is the first battery, as it requires a complete discharge before charge. So-called The effect of "memory" makes it very uncomfortable. The new alkaline battery requires a three-time cycle discharge - charge.

The general rule for all types of battery - the charge of the battery must be fully carried out, i.e. Before "Support."

Required charger qualities for automotive battery

The memory for AKB has the same principle of operation, namely: they must lower the network voltage to the battery rating, then straighten the voltage and ensure the automation of the battery charging process. Those. Ideally: the user must attach the charger terminals for the car battery, turn on the plug into the network and go to conscientiously relax until the morning.

Account charge methods that provide charger

  • . The charge passes relatively quickly, it's in a plus. In minus - this method due to the specifics of the charging process leads to a rapid "aging" of the AKB.
  • . As a lack of this method, there is too a stormy charge process at the beginning, and sluggish in the end.
  • Combined. Those. 2 B 1. It is the most optimal, and in principle, all modern chargers for the automotive battery are operating according to the third method.

How to choose a charger for a car battery

The first thing you need to do before you go to buy a memory for AKB is to thoroughly shist the instruction manual for your car in a part concerning the battery and the on-board network.

Then, already in the store, proceed to the study of the instructions for tactical and technical characteristics Selected charcinic.

Important! With the development of the counterfeit market, especially from the part of fraternal China, still give preference to the domestic producer. Winning will be obvious.

Select a charger with a small current in order to ensure that the zoom does not work at the limit. Or the situation may change, and you will need to charge the battery with a greater tank.

Select a charger for a car battery Stop on an automatic, providing a combined charge. The choice of the indication method is your taste and ... wallet. Discrete (LEDs) is less expensive, but also less accurate, although the consumer is sufficient. The instrument indication is more expensive and more accurate.

Types of charger for a car battery

  • Charging - Prepass. Carry out the charge and recipient of the battery. As a plus, it is allowed to connect to the UKB terminals, without disconnecting from the on-board network. This is important for.
  • Charger - launcher. Work in two modes: automated charge and return Max. Current in start-up. An unpleasant feature for the car owner is far from the electrician - it is recommended to fear the connection without removing the terminals from the battery. You can burn all the electronics of your car. Those. Requires the on-board network when recharging.
