Why do you even know the date of manufacture of the battery? This is not pies!
The fact is that any rechargeable battery occurs a natural self-discharge.
Lead-acid batteries have a memory property.
Speaking simply - the longer the battery is in a discharged (or charged not 100%) state, the harder it is to restore its resource by 100%.
That is why it is beneficial for the buyer to acquire the most fresh battery.
3 class batteries
In the modern market, 3 batteries manufacturing techniques are used: calcium, hybrid and minority.
Calcium Batteries (CA / CA) have the lowest self-discharge. This means that calcium batteries can cost longer without recharging without any irreversible consequences. Another advantage is undemanding for maintenance. Water from calcium batteries almost does not pump out, respectively, and add distilled water is not more often than once a year. Lack of calcium batteries - low resistance to deep discharges.
Malosurian Technology (SB / SB) The manufacture of batteries can be considered outdated. For modern accumulators of the passenger group, this technology is practically not used. The advantage of minority accumulators is high resistance to deep discharges. But at the same time, minority accumulators require constant care, since their inalienable features are intense watering and high levels of self-discharge. For such batteries, regular recharging and attachment of the prestivated water is required.
Hybrid Technology (CA / SB) is a combination of calcium and minority technology. Negative battery plates are manufactured according to calcium technology, and positive in classical minority technology. Accordingly, such batteries have middle level self-discharge, average maintenance and average resistance to deep discharge.
Calcium batteries can be stored without recharging 1 - 2 years.
Hybrid batteries can be stored without recharging 3 - 6 months.
Minor batteries require recharging already through 1 - 2 months after production.
On our site information about the technology of manufacturing each battery is indicated in detailed information In the line "Plates".
Why a battery, released half a year ago, can be considered fresh?
For example, you are looking for varta battery (calcium technology) and in all stores wherever you go, this battery is sold with the date of the production of one year old. It is quite clear that if in one single store in the city you will be able to find a wreat with a date of release of 6-month prescription - it will be a relatively fresh date.
Why are some battery brands in all stores for sale, on average, with a date of production of one year old?
Because some batteries are simply impossible to sell 1 - 2 months after they were released. This applies to those batteries that are brought from abroad. And it is for the reason that the transportation of these batteries only to official dealer May go to six months.
This applies to Varta, Energizer batteries and other foreign brands. Even if these are popular and well-discovered brands, sellers have no physical opportunity to sell them at an earlier age.
Absolutely different situation with BRAVO, AKOM and REACTOR batteries. The plant is nearby, therefore 90% of the Zhigulk batteries are sold at the age of 1 - 3 months.
From here we can conclude that if the Varta battery, for example, was released 1 year ago - this can be considered a "normal" manufacturing date and is few where you can find such a battery at least a little fresh. If you see AKOM battery, released 1 year ago, that is, it makes sense to search for other stores, where exactly the same battery can have a more recent date of manufacture.
Battery Storage Conditions in the Store
Each battery has a natural self-discharge. And the longer the battery is in a discharged state, the less likely to restore its resource is 100%. But what if the battery is regularly recharged?
For example, there is a beast battery in the store, which can be stored safe for its resource for 4 months. It takes 4 months - the battery did not sell. Then the seller puts the battery for charging and restores its resource up to 100%. The new and charged 100% battery has exactly the same characteristics as the battery just made.
But in practice, there are few people doing this. Neither employees of warehouses of official dealers, no sellers in retail stores.
The easiest I. reliable way Check battery charge
It turns out that it is necessary to determine the battery charge status. You must add several factors at once: the battery manufacturing technology, the battery brand and the likelihood that the battery charged or not charged to the sale.
In fact, everything is easier. The main indicator to be relying when buying a battery is an indicator of the battery checking for the load fork.
What kind of charge battery gives out without load and under load - it will definitely tell you whether the battery is 100% charged.
Why do we argue that we sell the freshest batteries?
All accumulators in the city buy goods from the same official dealers.
How fresh batteries are in a particular store depends on how long the store sold the battery from the moment he received it from the official dealer.
The specifics of our work is that we take the battery from the warehouse of the official dealer already after how the order came to us.
This means that we sell maximum fresh Batteries, as far as possible.
Very often, letters come to my site, about car batteries. Especially, one of the most popular - is it possible to put the battery on the machine greater tank? That is, the capacity of your battery, for example, 55 a * h (amp * hour), and you want to put the battery with a capacity of 70 Ah! What will happen and can I do this? Let's talk about it ...
Immediately I will say that there are many myths in this matter. For example - the car is laid by the battery at 60 Ah (according to the instructions), if you put on 50 Ah, it will boil, and if you put on 70 Ah it will not get enough!
This is not true! And the other battery you can put on your car, nothing terrible will happen, the most important thing is that they fit into the regular place of your car. After all, more capacious batteries have large sizes.
And now more details
If you do not go into deep technical details and speak in a simple language (yes forgive me the guru of electricians), the automotive network has some interconnection: the battery is the generator - the starter is the onboard network of the car. The onboard network of the car consumes little energy (ideally) if there is no additional energy-intensive equipment. The generator remains - the battery is the starter. Starter consumes energy only when the engine starts (it does not work further), it should be noted that in one start a passenger car "Averaged" is consumed about 1 - 2 ampere of the battery energy (in the cold time it can be much more).
After, the generator must fill the battery loss when starting the engine, that is, to recharge the battery. Usually, the voltage in the on-board network is about (13.8 - 14.2 volts) it is almost constant, it turns out this from the voltage of the on-board network minus the voltage of the battery itself (which is almost constant).
The generator also has its capacity characteristics - there are 40 A and 70 A and 80 A, etc., but this does not mean that this generator is sharpened under what battery. This characteristic indicates the maximum current that the generator can give an hour. But the current consumed by the battery (for recharging) is ten times lower than the generator produces.
What does this mean in practice?
If you put a battery greater tank, but with the same voltage, it just will be charged longer, let it not significantly, but longer! However, this means that it will also be discharged longer! Especially relevant in the frost, the current of the "larger" battery is enough for a greater number of "cold" starts!
If at all on the fingers ...
Imagine - there are two barrels of 55 liters and 70 liters (barrels are batteries). Both are equally filled with water with the same force (voltage in the car network), the barrels can not be filled immediately with water (that is, it is simply 55 and 70 liters for one second and 70 liters, it's not real and can destroy the barrel, but it is not necessary) On a decent (the same) water pressure, so that the barrel filoming is uniform (this water uniform pressure is uniform battery charging), then one barrel will be filled with 55 liters faster, another slower than 70 liters. But the water in another barrel (70 liters) will be greater and enough for longer. What turns out - batteries like barrels, only they are filled with energy, the container is measured in a / h, someone has 55, and someone has 70, etc. With the same currents (and now almost on all car, the same current is the same) one will be filled with energy faster, and the other longer. That's the whole difference!
In conclusion, I want to say, many want to put the battery not significantly greater capacity, for example, the factory 55 Ah, but they want to put 60 or 63 Ah - guys are nothing terrible, put! On the on-board network Car, battery - generator or starter, it will not have any influence.
Now a small video, look.
That's all, read our autosite.
In this post there will be my feedback to buy and use Chinese batteries for mobile phones.
As you know, the batteries in low-cost smartphones "live" about 1-2 years, after which they come into disrepair. Very often, this is expressed in a quick discharge of the battery when it can be discharged from 50 percent to zero. In this case, no calibration of the battery will no longer help and have to change it to the new one.
The easiest way to do it is to go and buy an original battery in the store. But unfortunately, this method is suitable only for those who have a smartphone company Samsung. Their batteries are found in our stores at a time price is easy. Especially in most Samsung phone models, the batteries are still removable.
But what to do if you bought Alcatel, Lenovo, Meizu or Huwei and in stores do not sell batteries for your phone or do you have a non-removable battery? In this case, you need to look for a battery on Chinese sites, the most popular of them.
When buying a battery on AliExpress, you should pay attention to the reviews about the battery and its price. Ridiculously buy a battery for 200 rubles, especially "high capacity" and natureyutsy Get long work from him. average cost Batteries on this site is 400-1000 rubles. Usually, high-tank batteries are used to the top bar of the cost, which have a special cover. Such batteries are larger than normal.
In addition, Aliexpress batteries are successfully resold in our various workshops. Very often they are sold under the guise of "original", with appropriateto her markup. For example, I bought a battery for Huawei G300 for 400 rubles on Aliexpress, but in our service centers exactly the same battery will cost 700 rubles + replacement if you do not remove the battery.
Remember that the main supplier of components in the service centers is Aliexpress and the phrase "not Chinese" battery from them can sound very strange.
Separately, I want to say about non-removable batteries. As for me, it is marketing trickSo that people more often change their phones. For the most part, such a non-removable battery is kept on a double-sided scotch and glued to the phone body, this is practiced by Meizu and Alcatel. In some cases, such as in Huawei, the battery is located behind a special frame that is screwed to the smartphone housing. In both cases, the battery connects to the device itself with a loop and remove it is not difficult, unless of course there is a necessary tool.
The most difficult when replacing the battery is to remove the back cover, especially if the manufacturer thought of it to stick to the housing or if it rests on the latches. To remove the back cover, we need an ordinary mediator, special repair kits for a particular phone are also sold on the site.
Car battery - seasonal goods, although it is used all year round. When birds sing on the street, and warm oil is splashing inside the engine, then scrolls the crankshaft is easy - even the half-hearted battery is coping with this. But in the cold starter is not easy, and it strives to turn into a purely active resistance that consumes a very long current. As a result, the battery strives to refuse, and the owner will have a campaign to the store.
How to choose a battery
If you do not want to contact the service or assistance to the seller, the selection algorithm should be the next one.
You need to take a battery that is guaranteed to fit into the niche allotted, be it motor compartment, trunk or something else. Agree: stupid to miss a couple of centimeters! At the same time, the polarity is determined: we look at the old battery and we think that it has on the right, and what's left? Of course, that if the car is not European, then the terminals themselves may differ from most familiar - both in form and location.
After that, choose a brand. Here we definitely advise you to follow the list of our winners recent years And never "peck" for beginners or outsiders. Even if their labels are the most beautiful. Here are some names from those that usually not let us down: Tyumen (Tyumen batteries), Varta, Medalist, A-Mega, Mutlu, Topla, "Act", "Beast".
Comparative tests of various car batteries we spend every year. The most recent results where we compared 10 batteries, you can see those who wish to familiarize themselves with the examinations of past years :,,, etc.
Battery brand, as a rule, determines its price. approximate cost European vending batteries with dimensions 242 × 175 × 190 mm in 2014 ranged from 3000 to 4800 rubles. For the usual battery, and from 6300 to 7750 rubles. - For AGM. The claimed current and the container will turn out by itself - based on the dimensions.
Important: If you have been installed aGM batterythen it should be changed only on AGM, and not on the "ordinary". The reverse replacement is quite admissible, but it is inexpedient economically.Now I charge the battery - even just purchased! Our experience shows: in stores under the guise of a new battery, you are happily squeezed "almost new", from which dust wipe out. We charge, connect instead of the old battery, and - the key to the start!
Those who are interested in technical nuances
Is it possible in the cold time before the start of the motor "imitate" the battery with the inclusion of headlights?
Why do you need an eye indicator?
This indicator allows you to roughly estimate the density and level of electrolyte to find out whether the car battery needs in recharging. By and large, this is a toy, because the eye is only in one bank out of six. However, many serious manufacturers at one time were forced to introduce it into the design, since the absence of the eye was perceived by consumers as a flaw.
Is it possible to estimate the state of the car battery voltage on the terminals?
Approximately possible. At room temperature, a fully charged battery, disconnected from loads, should produce at least 12.6-12.7 V.
What is hiding behind the term "calcium battery"?
Nothing special: this is an ordinary advertising move. Yes, the "CA" icons (and then "CA - CA") on car batteries today are still present, but they do not become easier. But calcium - metal is much less severe than lead. The thing is that we are talking about very small (shares or units of percentage) with calcium additives in the alloy from which the batteries are manufactured. If it is added to positive, and in negative electrodes, then the "sa - sa" is obtained. Such car batteries, with other things being equal, it is harder to boil, which is important for maintenance-free batteries. Less in such batteries and self-discharge during storage. Therefore, "ordinary" batteries with the addition of traditional antimony (they usually gives the presence of traffic jams) today on sale almost you will not meet! Note that not everything is so bad in them: for example, they are much better tolerant discharges!
Why do car batteries when checking give the claimed current so long?
Indeed, if the container is 60 A h, then the arithmetic prompts: current in 600 A should be issued about 0.1 hours or 6 minutes! And the real account is just tens of seconds ... The thing is that the battery capacity depends on the current! And with the specified current, the battery capacity is no longer 60 A, but much less: approximately 20-25! The inscription 60 and h speaks only that for 20 hours at a temperature of 25ºС, you can discharge your battery with a current equal to 60/20 \u003d 3A - and nothing more. At the same time, at the end of the discharge, the voltage at the outputs of the battery should not fall below 10.5 V.
Why choose the battery with the claimed current, say, 600 A, if the real need is half less?
The claimed current is also an indirect quality indicator. car battery: What it is higher, the lower his inner resistance! In addition, if you take an extreme case when, God forbid, the oil thickened so much that the starter in generally barely shifts the crankshaft, then the maximum possible current can be needed here.
Is it true that when installing a larger capacity on the car, it will be unsubstituted, and the starter can fail?
No it is not true. What prevents the battery to charge completely? It is appropriate to carry out an analogy: if you cried a glass of water from a bucket or from a huge barrel, then to restore the initial level of fluid, you will need to fasten the same glass from under the tap - both in the bucket and in the barrel. As for the expected starter breakage, its current consumption will not change, even if the battery capacity will grow in a hundred or thousand. Ohm's law from amps-hours does not depend.
Conversations about the upcoming breakdowns are appropriate except for extremals, accustomed to get out of the swamps at the starter. At the same time, the latter, understandable, is very hot, and therefore a small battery, which is discharged largely large, can save it from deadly overheating, dies first ... but this is a hypothetical case.
Immediately note one curious nuance. In Soviet times on a number army trucks It was strictly forbidden to install a car battery greater tank! But the reason was exactly the fact that when the engine did not want to start, the drivers often circled starters until the battery was discharged completely. At the same time, the starters were severely overheated and often faced. And the higher the battery capacity, the longer it was possible to mock the poor electric motor. It is to protect starters from such mockery that the requirement did not exceed the battery capacity above the "standard" appeared. But now it is irrelevant.
Question per million: What are they measured in amps-hours?
In any case, not the capacity of the batteries! This widespread misconception even in the environment of professionals. Which, however, are lost when they are asked how the product of the current does the container gives? Because the correct answer is this: Ampere-hour - Unit of measurement charge! 1 A h \u003d 3600 CL. And the container is measured in the Farrades: 1F \u003d 1kl / 1 V. Those who do not believe in it can refer to any directories - for example, to Boshevsky.
As for batteries, the confusing terminology is still alive. And what is actually charged is called the tank in the old way. Some textbooks are twisted - they say, "Capacity rate In amps-hours. " Do not measure, but evaluate! Well, that, at least so ...
By the way, in Soviet times, to choose the battery was incomparably easier - only by ampere-hour. Let's say on the "Volga" it was necessary to look for a car battery at 60 A, on "Zhiguli" -55 a h. Polarity and terminals on domestic cars There were the same. Today, it is not necessary to navigate only on the amp watch, because products different manufacturers With the same tank, they can be quite different at other parameters. Let's say, the batteries of 60 a h can have a 11 percent variation in height, 28 percent according to the claimed current, etc. At the same time, prices also live their lives.
And last. If, instead of "a h", you will see the inscription "A / C" (on the label, in the article, in advertising - it does not matter) - do not associate with this product. It costs uneducated and indifferent people who do not have an elementary presentation of electricity.
What is AGM battery?
The main scope of AGM is cars with "Start Stop" modes. This battery is even indicated: Start Stop!
The main scope of AGM is cars with "Start Stop" modes. This battery is even indicated: Start Stop!
Formally speaking, a car battery AGM is the same lead-acid product to which many generations of motorists are accustomed to, but at the same time it is much more perfect of their ancestors and will completely outset them in the near future.
AGM (Absorbent Glass Mat) is a technology for manufacturing accumulators with absorbed electrolyte, which are impregnated with separator micropores. The free volume of these microporers are used for closed recombination of gases, thereby not allowing water to evaporate. Hydrogen and oxygen, leaving the negative and positive plate, respectively, fall into the associated medium and are again connected, while remaining inside the battery. The internal resistance of such a battery is lower than that of the "liquid" predecessors, since the conductivity of the separator from fiberglass is better compared to traditional "envelopes" from polyethylene. So she is able to give more high Toki.. A tightly compressed package of plates interferes with the active mass to crumble, which allows you to withstand deep cyclic discharges. Such a car battery can work up to the legs. And if you split it into it, then even in this case there will be no poisonous puddles: the associated electrolyte must remain in separators.
Today's applications of AGM are cars with the "Start-Stop" mode, machines with increased power consumption (MES, "ambulance"), etc. But tomorrow "Simple" car battery will slowly go to the story ...
Are Agm and Conventional Batteries with each other?
Automotive aGM battery Replaces "Normal" 100%. Does such a replacement need if the car is enough good full battery is another question. But the reverse replacement, of course, is defective - it can be applied in practice only in a hopeless situation and as a temporary option.
Is it true that the car battery AGM is 50 a hours can be used instead of the usual 90 a h?
This, sorry, nonsense. How can you almost double to reduce the charge and say that there will be no difference? Lost ampere-clock does not compensate for any technology, even AGM.
Is it true that the high current of the battery AGM can destroy the car starter?
Of course not. The current is determined by the load resistance, and in this case - the starter. And even if the car battery can issue a current at a million amps, the starter will take exactly as much as from the ordinary battery. Violating the law of Ohm is not under power.
Which car is undesirable to apply AGM?
There is no such restriction. Even if we consider ancient machines with an absolutely defective relay-regulator and unstable voltage in the network, then in this case the AGM car battery is lined not before usual, but even later. The limit voltage above which trouble is possible is approximately 14.5 V for conventional batteries and 14.8 V for AGM.
What car battery is stronger afraid of deep discharge - AGM or ordinary?
Normal. After 5-6 deep discharges, they can finally "offended", while for AGM this number is practically unlimited.
Is it possible to count the car battery AGM fully maintenance?
This is a matter of well-established terminology, working more in favor of the PR, rather than science. Strictly speaking, this term is incorrect - both for AGM batteries and for any other car batteries. The fully challenged can be called except that the aa's finger battery, and any lead car battery, generally speaking, is not. Even the leader of the technology is AGM battery - is a hermetic, let's say, by 99%, but not 100%. And still you need to maintain such a battery - check charge, recharge if necessary, etc.
What do gel batteries differ from AGM?
At a minimum, the fact that gel car batteries ... does not exist! The question is generated by the established incorrect terminology: gel batteries are used, for example, in electric loaders or polomotive machines. The electrolyte in them, in contrast to conventional car batteries with liquid acid, is in a thickened state. AT rechargeable batteries with aGM technology The electrolyte is connected (saturator) in a special separator from fiberglass.
Note that the most popular Optima battery is also AGM, and not gel at all.
What is the reserve capacity of the battery?
This parameter shows how long the car will last a cold rainy at night, which has a spoiled generator. The expert will say otherwise: for how many minutes the voltage on the terminals of the battery issuing a current of 25 A will decrease to 10.5 V. Measurements are carried out at 25 ° C. The higher the result, the better.
We hope that our tips will help you choose the desired battery and refresh in memory of a curious "rechargeable" information.
Good luck on the roads!
