EFB batteries are considered an innovative future of rechargeable production. Many european manufacturers Already long ago switched to these technologies. The domestic market is just now starting to switch and produce similar acb. The technology is more affordable, but at the same time will last much longer. Many manufacturers represent this product. Having studied her features, advantages and ways of charge, it is worth making a choice in favor of EFB.

What is EFB battery
Enhanced flooded battery Translated from English means "Improvement Battery with Liquid Electrolite". The design uses thickened lead plates that have large capacity and recharging speed.
The microfiber is filled with a liquid sulfuric acid electrolyte as an envelope cover plates. This approach allows you to protect the plates from sulfate, short circuit, premature battery output. Security when applying such a model is guaranteed.
Where used EFB battery
Initially, they were created for cars with the START-STOP system, which is relevant for the European car market. If you use the usual battery, it will not stand a lot of starts during the day. But EFB technology can easily cope with it. Charging is carried out as quickly as possible, so even with a short trip, the generator compensates for the energy spent.
The scope of the battery is the most diverse and should not be limited to the car. They are used for boats, high-volume, hybrids, electric car. Unsuburnable benefits determine the product's popularity - long service life, resistance to deep discharges, quick charge.
Applied technology in EFB batteries
- The plates use more lead, compared to conventional lead acid batteries;
- Since lead more, the electrolyte itself is significantly less (about 3 times);
- Positively charged plates are wrapped in a special porous package that passes the electrolyte, but does not allow to settle the oxides that destroy the plates;
- Due to protection from, the battery became resistant to deep discharges (withstands up to 150 deep discharges);
- Purified lead is used, so the charge process proceeds much faster (the battery may be charged, even if you are driving in a traffic jam with the START-STOP system);
- Spikes on the plates are made according to vibration technologies, which reduces the risk mechanical damage plates;
- The modern labyrinth lid eliminates the possibility of pumping out the electrolyte (it is condensed and on special channels is sent to the lower part of the bank), which makes the battery fully maintained (shelf life up to 10 years or more);
Everything sealed batteries Equipped with pressure discharge valve. If the electrolyte will begin to boil strongly and the danger of an explosion of the battery will arise, the pairs (fluid electrolyte) will be reset through these valves. This can greatly reduce the level of fluid in banks, with the result that the battery will fail.
Advantages and disadvantages
Positive characteristics determine the popularity of the presented models:
- Resistance to discharges almost under zero. It restores the capacity to almost 100%. Conventional batteries in such cases lose part of the resource.
- Functions in the temperature range from -50 to +60 ° C.
- Starting current indicators are improved by 30-50% relative to the standard AKB;
- The electrolyte almost does not evaporate.
- Safe due to the absence of electrolyte evaporation.
- The current scroll current indicators are improved, allowing the device to operate in low temperatures.
- The discharge charge is a cycle that can be carried out more than once with ordinary batteries. In this, the functionality is preserved.
The main drawback is the high cost of the product, to which not every consumer is solved.
Difference EFB from AGM
AGM and EFB technologies are similar to each other, the main difference is in the electrolyte used. In the first case, liquid is used, fiberglass acts as an envelope. This option is not completely poured.
In the EEF, it is also liquid, with a shaking even heard, as it flies, but it is significantly less, and the plates are wrapped tightly. Electrochemical fluid is not sealed inside fiberglass. We can say that EFB technology is something average between ordinary battery and AGM.
Construction differences can be attributed to:
- The thickness of the plate is greater, and therefore the duration of operation increases.
- With a smaller number of electrolyte and the use of purified lead, the charge accumulates by 45%.
- EFB will cost AGM cheaper. However, the latter possess best characteristicsWhat is proved by alphaline batteries.
How to charge EFB battery
To charge such a battery, you do not have to study anything new. Due to the similar design, the process is of the same character as when charging AMG. The main thing in this business is the reconciliation of high quality charger and following instructions. The voltage of the charger should not exceed 14.4 V. Well, if the memory has an indication of the current, which allows you to track the indicator.
When the device is connected to the terminals, it is important to observe polarity. If charging falls below 2.5 A, then the charging process can be considered complete. It is not necessary to use the accelerated regime in order not to face the problem of increased gas formation. The plug is not allowed, which can lead to a change in chemical equilibrium.
Which EFB battery is better to choose
Among domestic producers Products are popular with popularity:
- represented by seven types of batteries whose capacity varies from 55 to 100 A / h. The cost of products corresponds to the stated characteristics.
- Due to the use of special additives, Ultimatum batteries have an improved charge reception and work resource.
- The combination of flawless assembly and modern technologies is the products of the domestic enterprise. Among the extensive range, each consumer will be able to find a suitable model.
Among foreign manufacturers can not be part of:
- Varta Blue Dynamic is a whole line from Varta, which is devoted to products with EFB technology. It is characterized by a capacity and price.
- Turkish manufacturer for 60 years of existence on the market offers a wide range of batteries for passenger cars and trucks. At the expense of good indicators, the products are installed on the car in the primary factory configuration.
- Bosch S5 - battery that was created under the famous stop technology GO. Allows you to save fuel, reduces emissions and noise by reducing idling time.
Owned complete information It's not so difficult to make a choice in favor of a specific EFB.
You had or have a battery with eFB technology? Then tell in the comments about your impressions about him, it will very help the rest of motorists and make the material more complete and accurate.
Leader in production rechargeable batteries in Russia 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 when 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 preheating 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.

* Calculated using Rosstat data on the first half of 2017 in terms of production in the Russian Federation.
Most recently, EFB accumulators have become increasing among motorists, which many have not heard anything before and did not know anything. And this is understandable: it has become quite recent to produce them. Abroad, such a kind of rechargeable batteries began to be produced only a few years ago, and recently in Russia, the state funded one of the domestic companies "AKOM" specifically in order for it to produce an acb of precisely this type.
In order to correctly evaluate whether it is worth buying such a battery for the car, you need to dispel a popular misconception from the fact that EFB batteries are the same as the more famous.
What is EFB and how does it differ from AGM?
Despite the fact that technical characteristics These two types of batteries are quite similar, nevertheless, there are non-critical, but fundamental differences in their production technology. Abbreviation EFB on english language sounds like Enhanced Flooded Battery.that translated into Russian means " improved liquid electrolyte battery ».
So, the features and advantages of ETB batteries look like this:
- The plates of them have improved characteristics. . In production, much more lead is used than in ordinary starter batteries.
- The plus plates are wrapped in the package (envelope), which, literally, seals the plate, not allowing it to collapse and prevent sulfate . Porous package, it passes the liquid, which is important.
- Lead used only peeled The plates are volumetric, more powerful, stronger, so the charge and battery discharge occur much faster.
- Plates are resistant to deep discharges, since they do not settle oxides . Essential plus EFB batteries - if the battery is discharged to 50%, it will still serve for a long time, unlike many analogues.
- Deep discharges "Improved" 4 times (oxides settle, but not so intense, both in a conventional battery), and it can withstand much more deep discharges. For comparison: the usual acid battery can withstand 20, from force 25, and EFB can stand 100-150 deep discharges.
- Service life 10 years and more .
- Spikes between the plates of vibration resistant, designed for a car shaking .
- In the inner design of the battery there are also special funnels that contribute to constant mixing of electrolyte , which is particularly favorably reflected on the productivity of the battery. With its work, the electrolyte, evaporated, goes upstairs into a funnel made in the form of a snail. This form contributes to the fact that after the receipt of the electrolyte in a funnel, it lowers it to the bottom of the banks. Thus, a more uniform mixing of the liquid is ensured.
- EFB battery, for the most part, that is very convenient. Although Russian manufacturers produce a more "budget" served version of Ultimatum.
- Do not "degrade" at high temperatures .
- Starting current increased by 30-50% That makes it possible to easily run the car engine even at extremely negative temperatures.
Such detailed review Must help drivers to deal with the benefits of a new generation batteries.
As for their differences from AGM, they are fundamental - in terms of their manufacturing technology. W. AGM batteries The liquid electrolyte is sealed in fiberglass, the plates of which are locked between "plus" and "minus" batteries plates. There is no fluid substance inside. In EFB batteries, the electrolyte is still liquid, not "packaged" in fiberglass. Package (or envelope) holds a plus plate and does not give her to crumble.
The price of EFB batteries and the scope of their application
The cost of such batteries pleases: on many russian cars Soon you can see the batteries russian production. It is encouraging that russian manufacturer Does not ignore the next stage of evolution in the manufacture of acb, and trying to keep up with European and Japanese colleagues.
The average price of such a battery is 6000-7500 rubles. In this case, it has much stronger starting currents and longer service life. In addition, the scope of application of these batteries is very wide and safe: they can be used even in solar and wind power installations, on boats, in auto-volumes and electric vehicles.
Ultimatum - Russian alternative to foreign manufacturers
The company "AKOM" is engaged in the production of EFB batteries since 2014. It is amazing, but in a short time, our manufacturers could even beat overall colleagues in something, developing the EFB battery of the Ultimatum type, fully adapted to Russian conditions and familiar to many drivers. Special good feedback It is left for motorists of old hardening, which still remember the "old good" serviced "acids".
Ultimatum battery was launched in mass production In 2015.
It is worth describing the benefits of this particular battery separately, because many ask about what the pluses are the EFB battery from AKOM:
- It is resistant to extreme temperatures and can work in the most severe Russian conditions. . Even with frosts 50-60 ° C, the electrolyte does not turn into ice crystals.
- With a standard capacity of 60 Ah, its starting current is 550 A that several times more than the usual "acid". This allows you to quickly start the engine even in the most fierce frost.
- It fully meets the needs of cars equipped with start-stop systems that does not allow a quick discharge with short-term travel or frequent stops in urban traffic jams.
- significantly higher . This battery can be easily stored for two years in stock or in the store without prejudice to the indicators of its nominal capacity.
- The inscription "Double resource" on the battery case fully corresponds to it technical advantages - such as extreme resistance and increased strength of improved lead plates.
- Ultimatum, like all high-quality EFB batteries, especially resistant to deep discharge .
- Not afraid of turning at an angle of 45 ° . This makes it safe to its use on various plaques and SUVs participating in competitions with cool virages.
- 4 years warranty from the date of production .
- It has built-in To control and level the electrolyte and refers to the usual maintenance type of ACB.
When carrying out one of the tests, it turned out that this battery is "holding" high capacity capacities for one and a half months after the start of the test. With the original container, about 100%, the figures for a month and a half decreased only to 91.5%. The load given by the battery all this time was equal to that which is standard for three years. This means that in the first three years of operation, Ultimatum is not so much capacity, even in comparison with imported analogues.
Thus, become clear similarities, differences and features between the batteries of a new generation. And the ability to purchase a high-quality battery of Russian production can be an additional incentive for drivers in order for EFB technology to become a much greater number of consumers in our country.
Enhanced Flooded Battery (EFB) or, speaking in Russian, improved rechargeable battery with liquid electrolyte. The battery produced by such technology differs from the familiar "classic" battery with plates, each of which is enclosed in a special package - separator. The surface of the plates is better protected from sulfate, the battery is not afraid of "squeezing" of plates.
As a result, the battery with improved EFB technology is a resistant to deep discharge and cyclic loads, it easily tolerates numerous charge-discharge cycles, has increased cold start currents, it restores the charge faster, it works in a wide range of temperatures, which is especially relevant for Russia. And still tolerate peak loads and almost does not evaporate the electrolyte.
Now, armed with a minimum of knowledge about the new technology, we will try to go through the meeting of the most outstanding misconceptions about the accumulators with improved EFB technology.
Myth First - EFB batteries are produced abroad, so the price of them is very high. Yes, of course, they produce them abroad, and until recently, such batteries were not available to everyone. But now, the leader in the production of batteries in Russia, factory Releases and battery series "AKOM + EFB". Using that very innovative technologyWhat can be seen even from the name. And the price of them is significantly lower foreign analogsAt the same time, thanks to multi-stage production control, the quality is not inferior to world counterparts.
Myth two - Batteries with improved EFB technology are afraid of Russian frosts. All batteries do not like strong frostsBut the accumulators "AKOM + EFB" are afraid of them significantly less. They better tolerate peak loads when starting a cold engine and are rapidly restored. Of course, if you wish, and such a battery can be planted "in zero". But let's remember the resistance to a deep discharge. Charged and you can turn the starter again! Can better Engine In order to bring?
Myth Third - accumulators with improved EFB technology can only be installed on dear cars With Start-Stop. Can not, but should! The stability of the battery to cyclic loads is extremely important here. For such cars, they are a "mandatory program". AND russian battery "AKOM + EFB" is superbly working on an imported business sedan. Also, however, as in any other car. Is owners budgetary cars Do not stand in many hours of traffic jams when the batteries are barely enough for headlights-heating-music heated seats and other benefits?!
Do not start the motor in a strong frost, are not interested in the durability of your battery?! Thus, AKOM + EFB batteries are designed not only for cars with the START-STOP system or for cars equipped with additional sources of power consumption - light, powerful sound systems, winches, preheaters, spotlights, inverters, etc., but also for ordinary cars.
Myth Fourth - just about durability. Say, EFB - Batteries live for a short time. How long is that the same Russian manufacturer declares the doubled resource of such batteries and gives a four-year warranty on its AKO + EFB line.
Let's go back a little back and recall the improved protection against sulfate, resistance to peel plates, resistance to deep discharges. Batteries with improved EFB technology can be operated significantly longer than the classic starter battery.
Myth Fifth - EFB is non-serious. Here are C. batteries aGM technology Or gel batteries - this is a thing! And the truth is the thing! Without any irony. But, as any "thing" - has a considerable price. EFB batteries for most parameters are not inferior to "dry" batteries, and somewhere exceeding them. For example, the charge is rapidly taken. And at the same time it is noticeable cheaper! And, run ahead, the same AKOM prepares to withdraw to the battery market with AGM technology in 2018, which means that this technology will soon become more accessible to Russians.
Given the possibilities and dignity of the battery with EFB technology, this is a reasonable purchase that will serve not one year. In the AKOM + EFB line, seven models with a capacity of 55 to 100 Ah with straight and reverse polarity - You can choose a battery for almost any car. Batteries using improved EFB technology are perfectly suitable car enthusiasts, accustomed to getting better and not compromise, losing in quality.
The leader in the production of batteries in Russia - the AKOM plant has prepared a novelty for motorists - a battery with improved EFB technology that meets international quality standards. Thanks to the improvement of the separator and the design of the plates, the life resource of the novelty is doubled, in comparison with a conventional battery. Most importantly - in the new battery launchers are significantly increased.
In 2017, AKOM + EFB battery became the winner of the Innovative Product of Russia.
Akom + EFB is: 1. Extended warranty - 4 years.
Confidence in the quality of products - providing a guarantee for almost entire battery life.
