Not so long ago one of domestic producers Began the production of batteries using EFB technology (it is worth noting in Europe such manufacturers already mass). A completely new technology will be more accessible (let's say AGM battery) And at the same time more durable (than ordinary lead). EFB is a real future of our battery industry, for such ankb should be slightly overpayed, because they work better and more durable by about twice. Do not know what it is? Then it is an article for you ...
To start as usual definition
EFB batteries ( Enhanced Flooded Battery - Improved Battery with Liquid Electrolite) - This is improved lead Akbin which the liquid electrolyte is used. The plates are also made of lead (they are massive than in conventional batteries), each plate is wrapped in a special "package" from the microfiber. This package is constantly impregnated with electrolyte and fits tightly to the active surface. Also he protects the surface from negative consequences, such as, which occurs at.
It is really a step forward, it is worth noting that they can work at times more than say lead analogs from the previous generation.
Why works longer than ordinary batteries?
Actually, everything is simple, as I wrote from above is an improved technology. Let's try in contractions (compare with the usual battery):
- Plates thicker. Due to their thickness work much longer
- Each plate is wrapped in a package of special material that is impregnated with electrolyte
- Double resource, at the expense of new technologies
- More resistant to deep discharges. If the usual starter battery loses about 5% of the container with each deep discharge, then EFB variants are restored to almost 100% capacity
- At high temperatures, the corrosion activity of the electrolyte is reduced by 40%
- Work from - 50 degrees, to + 60 degrees Celsius
- Reduced electrolyte volume, about three times
- Due to the smaller volume of electrochemical fluid and the use of purified lead, charge accumulates by 45% faster
- Improved indicators, from 30 to 50%
- Safe and practically not serviced, you can even use at home, there is no electrolyte evaporation
As you can see a lot of differences, all of them increase the characteristics in best side. There are practically no negative moments, but about it a little later.
About electrolyte
Probably, now many read and think - what differences EFB. I will practically say from AGM technology! Yes, indeed, they are very similar, I would even say - very similar! However, it is a little different, the difference is right here in the electrolyte.
AGM is liquid, but it is sealed in mats from fiberglass, that is, it can be said - which is practically not poured.
At EFB, it is the same liquid as the usual starter batteries, if you want it plumps between the plates, but it is smaller, and the plates themselves are as it were in envelopes, tritely wrapped.
That is, you need to understand, EFB technology is an intermediate stage between the usual starter AKB and AGM. It is used precisely liquid electrochemical fluid!
Moreover, it is not sealed inside the fiberglass, namely physically flowing.
Where applies
You know, initially such ankb was developed for the start-stop system, now in Europe it is very relevant. The usual battery will not be able to keep many starts during the day, but the EFB technology (well, or more expensive AGM) is easily. They are very quickly charged, and therefore the generator even with a short trip will be able to compensate for the energy spent.
But manufacturers assure that applied is not limited to the car. It is also possible to apply in boats, auto-volumes, hybrids, electrocars, even in alternative systems, for energy accumulation. There are several undeniable advantages. This is a resistance to deep discharges, a quick charge and long service life.
Price and appropriate application
To be honest, many technologies, such as GEL or AGM, are not always cheap. Therefore, it is easier to buy several ordinary batteries than one - gel. And how are things going with EFB, maybe the price is also not justified overestimated?
There is no here everything is in order. The cost is about 30% more than the usual starter battery, not two or three times as in opponents.
For example, lead battery Russian production At 60 ap * h stands from 4,000 to 5,000 rubles (I take normal options, and not made from foil). The EFB will cost 6000 - 6500 rubles, not critical, is it true?
But the service life, starting currents, warranty and other pleasantness are much more. And there is a possibility that it takes place not 4 years, but at least 6 - 7 years.
What is pleasant pleased, now they launched the batteries of Russian production, that is, not only an imported product on the shelves.
Now a little video is watching
Now you know what kind of technology, and you will not slap in your eyes in the battery store.
On this end, I think my article was useful to you, sincerely your helf.

Good morning! Today, I - I - I - Oleg's blog Alexei a_KATKOV. from Moscow. We are talking about car batteries. I do not promise short. I can tell your work for hours, but only because I love her very much!
For many years of work on the market, I worked with a lot of factories and only one of them became a partner for life. Today, our company is the official representative of the German Moll plant in Russia - official supplier Audi, VW, Porsche, Skoda, Liebherr special equipment.
It should be noted that when I started work in the 90s sense in such a liberation, as today, there was absolutely no. And for what reasons he needed today:
1) The composition of the movement participants has changed. Last year we passed that a significant feature when 50% of men and 50% of women were driving. That is, women confidently and actively crowded the floor and become car enthusiasts. This time. The generation of car owners came, who do not know what is under the hood, and do not want to know. These are two.
Result: low level Knowledge of the processes occurring in the car, lack of care for the battery and electrical equipment. Previously, each self-respecting motorist was charger And everyone knew what to charge the battery. Today we know cases when people do not know where the car's hood opens. There is no understanding of many processes. Most battery seems to be such a bottomless barrel with energy, from where you can pick up and pick up: forget the headlights included, listen to music on the beach, pick up huge speakers, webasts, navigators, etc. and then as in a joke: "And what? Also you need to charge? "
In the electrical circuit of the car initially it is assumed that a fully charged battery is connected to it. Next, this battery gives part of the energy to start the engine and the generator turns on with the engine. Next, the method of the generator includes constant energy generation for the entire car and also returning back the battery lost part to them to start the engine.
Battery on the car is used to power electric starter When starting the engine, to supply the energy of consumers with a non-working engine and when working in a small speed of rotation (read the cork), as well as for a common generator set Power consumers in the case when their power exceeds the generator power (our cases with a giant number of consumers: navigation, heated, webasts).
And all the cones, as usual in our life, also gets a battery - an ordinary, but key employee in power supply. Take one frost morning in the car: everything starts with the battery - he readily gives part of the energy to launch the engine and immediately begins to feed all the energy consumers: climate control, radio tape recorder and someone and TV, janitors, blowing glass, heating all glasses , mirrors, chairs and steering, as well as light bulbs and headlights, which somehow light up in the dark.
The generator of course also tries to fill such a sharp analysis of energy and it is important to chemical processes Inside the battery were ready at a deep minus temperature readily to take maximum energy from the generator. But usually, for the full launch of all chemical processes, the battery must warm up well under the hood of the car, and this happens only during the movement of the machine on the way, and this path must be quite long. It is much better if the battery is installed in the cabin or in the car trunk, but there are not very much such models.
So, the main reason for "chronic submature" battery in winter time - Its inability to immediately take maximum energy from the generator at a deep minus temperature.
Why it happens that in the summer the car enthusiast is not experiencing any problems with the start of the engine, but in winter even relative new battery Will not always get the car in the morning? This suggests that the battery "Chronically" is in the "unsavded" condition. In the summer, his charge is enough to start the engine, but in the winter in the frost, when significant additional energy is required - no longer.
Out of here simple - in winter, the battery must be fully charged. . The easiest way to avoid problems in frosts is to check the battery level of the battery immediately after you have seen the weather forecast where "minus" appears. Do not forget that two temperature points are especially dangerous - the transition through zero, and the first frost -20c.
This procedure is not superfluous anyway: whatever the battery you have, no matter how new the car is. At any trading pointwhere batteries are sold, always help measure the degree of charging the battery. Just get this 15 minutes on the way home.
How to deal with underwear?Yes, in general, just, here are the main tips, some of which are useful in winter time to all motorists, even if everything is in order:
1. In the evening, before turning off the engine, be sure to turn off all energy consumables: climate control, radio tape recorder, janitors, blowing glass, heating all glasses, mirrors, chairs, steering, all light bulbs and emerge lights. This will help the battery in the morning focus on the main task - starting the engine, and do not spray the efforts on the electrical appliances forgotten from the evening that you can enable later.
2. Next after the engine started, include only the necessary electrical appliances and gradually, as needed, leaving, such as radio, TV, multimedia system For a while, when the car really warm up well.
3. If you leave the car for a week or more, then besides the mandatory execution of paragraph 1, do not turn on the alarm, and simply the key close the door. Of course, in this case, it is advisable to put the car on the guarded parking lot. Many, leaving the car for a very long time, let's say for two or three months, then they are horrified with screams: "It does not start!", And it was enough to disconnect the minus terminal of the car from the battery. The battery in this case will save all the energy for the main task - the engine starts on your first requirement.
4. If for some reason you buy a new battery on your car, choose batteries famous manufacturerswhich supply their products to the conveyors of high-tech cars. The technologies of these manufacturers were already far ahead and many problems, for example, the rapid reception of the maximum energy at a deep minus temperature, they are resolved.
2) the structure of the fleet has changed. Appeared hybrid cars, Cars equipped with start-stop and I-STOP systems.
The usual battery with classical technology is categorically not suitable for vehicles with fuel economy system, the so-called i-Stop or Start-Stop, which turns off the engine on each traffic light or in the traffic jam during the machine stop. Then, when the pedal is pressed, the engine automatically starts and the movement continues. The battery in this mode should be so technologically, that the usual batteries such a mode of operation is unable. After all, during each stop, until the engine with the generator is disconnected, all electrical appliances remain in working condition - multimedia, climate control, wipers in the rain, heating and blowing, and in the dark and headlights work in the usual mode on the shoulders of the battery alone. At the same time, he has enough energy for the subsequent start of the engine.
And as soon as the engine and, accordingly, the generator wound up, the battery should urgently take the maximum energy to the next traffic light. Considering the fact that from the traffic light to the traffic light, you can crawl in a sluggling plug. In such a battery, even with extremely low temperatures Chemical processes are launched almost instantly, and it is absolutely not terrible urban operating conditions, which today relate to heavy conditions operation.
3) changed the nature of the movement. We all "fight" in automotive traffic jams, in the morning "occupy a queue" in one direction, in the evening - to another. The time of "free" movement decreased to a minimum.
The effectiveness of the charge in such conditions is reduced. The result is natural - the battery operates in short-term mode.
The solution option is all the same: the choice of the battery is fast receiving and quickly giving AGM or EFB. Either a standard battery with regular control level and recovery from a charger.
4) the load on the battery has changed due to the advent of a large number additional equipment.
Webasters, heated seats, navigation systems - All this requires nutrition. Often the amount of this additional equipment is so large that the regular battery is simply not able to "digest" such a load. Of course, cars are already moving from the conveyor where special system Battery charge level. And the on-board computer itself turns off the additional sources in the event of a critical drop in the battery charge. But still it is not a massive case.
Solution Options:
1) bring the amount of electrical equipment to a reasonable state
2) use AGM / EFB batteries that can quickly return the charge when driving
3) Put an additional battery (but there are difficulties in harmonizing this with a generator power and in general the embodiment of this scheme)
5) reduced distance distance. If earlier "our people do not go to Bulosha on a taxi," today it is very much. And not only in the bull. To be fused to mail, drive to the library, ride for the child to the garden, etc., and pr - minimum distances for saving time, we overcome by car.
Suppose that the owner of the car lives not far from work and, remembering a little in traffic (when the generator misses), he has already arrived. The engine and with it the generator is turned off, and the battery takes all the work on energy supply. He drags the string of the belt on the belt and begins to patiently feed the alarm.
Next, dinner time and everything is repeated: the battery gives a lot, but does not have time to take a lot, since the cafe is even closer than the car owner house and the battery does not have time to warm up and establish its chemical processes. In the evening - yes, everything is also, and again all night turns on the alarm - be kind provide its energy.
Regular underwear - based cause of the output of batteries in order in conditions of large cities in our time.
It can be solved in two ways:
1) Choosing a battery quickly receiving and quickly giving AGM / EFB charge (which is fast and convenient)
2) Regular checking of the battery level and recharging if necessary (which is not very convenient - it is necessary to have a charger, time and place for charging. Yes, and the battery should be removed and charged. Under conditions on-board computers, installation of the battery under the seat seat or in the trunk is not a simple event at all)
Now about technology. All of them can be divided into two groups:
1. Classic lead batteries
2. New technologies
I will not dwell on the "classics", I will tell you what's new!
New technologies.
Information about the technology used is usually written directly on the battery label. Be careful!
Gel technology Gel - Gel ElectroLite.The eellecratic in these batteries is in the gel state, this is due to the content of silicon compounds in it.
Gel acb champions for resistance to deep discharge and can withstand a record number of deep discharge cycles. Even despite the obvious advantages of gel batteries, they did not receive recognition among motorists, the reason for this was the high demands for onboard electrical equipment and due to a sharp reduction in the starting current in cold conditions. In addition, the price has become an important factor in the "cut-off".
Against the background of the high cost of gel batteries, the needs of automakers in such a product are increasingly distributed AGM battery.
- AGM. The battery with an electrolyte, absorbed into a special separator of fiberglass (such a battery is often called "gel" since the fiberglass with an electrolyte becomes jelly-like), characterized by maximum resistance to the discharge-charge cycles, record starter currents and charge rate.
The main feature is almost 100% recombination of gases. In them, the products of the chemical reaction (hydrogen, oxygen) between electrodes and electrolytes are not thrown into the external environment, and remain in the pores of fiberglass. These gases when charging the battery again become part of the electrolyte. Battery performance is saved for a long time.
Due to the tight fit of the plates and the efficiency of the efficiency (rate of return and charge) increases dramatically. And this means high launchers, easy engine start and other pleasant advantages. Such batteries are small sensitive to vibrations - lead paste just nowhere to be saturated. You can operate in any condition: vertically - horizontally and even if the case damage does not lose its properties. Another plus is the widest range of applications - from road transport to solar installations.
Until recently, it was an absolute leader among new technological batteries. However, no minuses are not deprived. AGM batteries are afraid of high temperatures, reloading and very expensive. Therefore, automakers that establish such types of batteries on the conveyor, try to transfer the battery to the trunk or under the driver's seat or choose a more budget option.
Regular outcome of the fight for the price and the quality has become EFB technology developed by the German Moll plant, which intends to save all the properties of AGM batteries.
Optimized EFB technology ( Enhanced Flooded Battery) with a special microfiber envelope.
Comes today the primary configuration of cars with the Start-Stop system to all European conveyors. From the main advantages - Three-time increase of sustainability to cycles compared to an ordinary starter battery and Increased twice charger, allowing you to quickly compensate for the discharge during the movement of the car. These batteries are not afraid of inclination - the electrolyte does not follow at the angles of tilt up to 55 degrees.
High pads Significantly exceeds the indicators of the conventional battery at a temperature of -18. The service life is significantly increased. Does not require topping the water during operation.
On my personal view (and the view of European automakers) is the ideal technology today and the best choice For any car. Ideally works in urban cycles, short-term and still cheaper than gel and AGM.
A little about sales:
At the time of sale right with you the seller must:
1) Measure the electrical indicators to it acb, i.e.
-Eads, (she is the same voltage of the open chain (RTC), it is the same stress without load, it is also tension idle move) EMF charged battery should be 12.7 (+0.1) in
- and voltages under load. The voltage under load for the battery capacity of 50-65 A.Ch is the voltage will be 10-10.5V, for the battery capacity of 65-85a.ch approximately 10-10.8V, for AKB 90-110 A.Ch to 11.0 V, For AKB Over 132 A.Ch is usually above 11.1-11.5V.
2) Fill out a warranty card with an indication of the manufacturer, the location of the warranty workshop and the warranty period, as well as the indicators that were measured above. The warranty card is not issued in order to put it in the glove box. Carefully read it as any instruction. Let me remind you that in accordance with the law, the warranty period on the battery is calculated not from the date of production, but from the date of sale of its consumer.
3) to issue cash register or commodity depending on the form of tax reporting.
The choice of battery is responsible, and if you do everything right - no frosts are terrible!
Please ask questions!
Among domestic car owners are becoming increasingly popular with rechargeable batteries manufactured based on the innovative EFB technology. It is not surprising, after all, the use for their manufacture of an improved design of plates and separator ensures an increase in the resource of such batteries almost twice in comparison with standard models. Compared to conventional batteries, the batteries EFB significantly increased the number of discharge-charge cycles - on average three times higher. Above these rechargeable batteries and resistance to deep discharges, as well as the recovery rate after discharge. EFB batteries are characterized by quite high values \u200b\u200bof starting currents.
What are rechargeableEFB. Battery?
Batteries EFB. - New in the current market of battery technology. Their name is an abbreviation from "EnhancedFloodedBattery.". WITH in English it translates as "improvedliquid filledbattery".
In fact, EFB batteries are the same lead-acid battles, filled with electrolyte. Almost all of these models are sold with flooded, in charged and fully prepared for operation. Compared with conventional car wet batteries, they have some improvements. The main modernization is the application to stabilize the active substance on the lead plates of the battery of a special material.
In EFB batteries, they use thicker than in traditional batteries, lead plates, due to which the capacity of the batteries and the speed of their charging is significantly increased. The plates are concluded in the envelopes from the microfiber, inside of which there is a liquid sulfur electrolyte, which protects their surfaces from sulfate, short circuit, and is also prevention of too fast wear.
The main advantages of EFB batteries:
- provide maximum fast charging;
- not afraid of deep discharges and cyclic loads;
- unlike conventional batteries, the initial container after a deep discharge is almost completely restored, without losing part of the resource;
- able to work in a wide temperature range;
- have improved on a third launch current indicators;
- liquid electrolyte almost does not evaporate;
- characterized by a doubled recharge cycles.
EFB Batteries have become an improved replacement of the usual AGM. In European countries, manufacturers and workers of car servicemen have already moved to such batteries. Today, these innovative technologies Reached and domestic car market.
The presence of the above advantages made EFB batteries much more perfect than Gel and AGM batteries. Today, such batteries are used not only in car structures. They are also installed in boats, electric vehicles, etc. Especially convenient to use such batteries in cars operating on the basis of the "Start-Stop" technology.
Leader in the production of batteries in Russia * and the largest supplier The conveyors of world automakers in the Russian Federation - the plant "AKOM" prepared a novelty for motorists: a battery with improved EFB technology, which corresponds to international quality standards. Due to the improvement of the separator and the design of the plates, the life resource of the novelty is doubled compared to the usual starter battery. The battery has increased resistance to deep discharge and corrosive processes, has an extended warranty - four years. Most importantly - in the new battery launchers are significantly increased. This product is perfectly suitable to motorists who are accustomed to getting the best and not compromise, losing in quality.
Batteries manufactured using EFB technology are becoming increasingly popular among Russian motorists. We will deal with what they are good, and we denote the scope of their use.
Imagine typical operating conditions a passenger car in the town. As a rule, these are short trips with movements in traffic jams during which the engine works for a long time on idling. What happens to the usual battery? When the car starts, it is strongly discharged and further does not have time to charge - the generator when the engine running at idult may not provide sufficient power for charge, especially when the powerful powerful power consumers (light, sound, air conditioning, winch, heated mirrors, etc. ). It turns out that the generator is capable of charging the battery only in those intervals when the car moves at a normal speed - 40-60 km / h. But such periods are quite short, and the ability of the usual battery take the charge is not very high, especially at low temperatures. As a result, we receive deep discharges, chronic underwent, which leads to a reduction in battery life.
For such operating conditions, it is advisable to have a battery that is not afraid of deep discharges and is able to quickly charge. Until recently, such parameters could only provide AGM batteries, but in ordinary cars They were practically not used due to very high prices.
The emergence of EFB technology in Russia made it possible to resolve this contradiction. Unlike a conventional battery, the plates in the EFB-battery are covered with a special film that prevents their sprinkling at a deep discharge. In addition, the battery plates themselves have become more resistant to corrosion due to the use of improved chemical composition. In addition, EFB batteries are able to make a charge more efficiently, time to "restore sports form" even during short trips in traffic jams. The service life of such batteries is twice as much as the usual. In this case, the battery with EFB technology is noticeably cheaper than AGM batteries.
To date, batteries made using EFB technology are completed with the START-STOP system. But they are recommended to those motorists who often drive in urban mode - for the battery this mode with constantly alternating charge cycles and discharge more and more reminds driving with constant starts and engine stops. Batteries with improved EFB technology are also suitable for cars equipped with additional options and powerful electricity consumers, such as preparation heaters, winches, inverters for charging gadgets, additional lighting devices, xenon and powerful sound systems. They are convenient when using a car in a taxi mode.
So, the accumulator battery "AKOM + EFB" is a modern and reliable product.
These batteries have a number of advantages over conventional starter batteries:
- double resource and resistance to cyclic loads; Over 240 charge-discharge cycles, that is, two times more than the usual starter battery;
- increased starting currents in comparison with conventional calcium batteries;
- not afraid of deep discharges;
- increased corrosive resistance of electrodes at high temperatures;
- the minimum battery charge time due to improved charging current reception.
And an important fact is a big warranty period. At accumulatory batteries AKOM + EFB, it is increased to four years.
Accumulators "AKOM + EFB" is another proof that the rechargeable battery produced in Russia is not inferior to imported analogues and is able to provide its owner a new level of comfort and quality. The use of improved technology provides accumulators AKO + EFB combination of high starting power and increased resource.
