In the automotive sector, traditional lead-acid batteries (FLA) are still an important choice for starting cars and electronic devices in vehicles. But after all, lead-acid batteries have a short lifespan, are prone to bulging, are larger in size, and several other issues that no longer provide a more convenient sense of use for most people. This calls for more powerful batteries, and EFB batteries are a great choice. In this article we will introduce you to EFB batteries.

1.What is EFB battery?
In fact, EFB battery is an upgraded version of the traditional lead-acid battery. Its battery tank removes the solid components such as plates, separators, etc. The remaining space of these components is filled with electrolyte, and the electrolysis is also in a state of excess.The battery closure of EFB battery is a movable battery cover, which makes the concentration of electrolyte air-conditioning to be adjusted by adding distilled water.
2. Advantages of EFB battery
Higher energy density: EFB batteries use more advanced technology and process, so that its energy density will be higher, can provide temperature power output.
Higher safety: The electrode material and electrolyte of EFB batteries are better sealed, and generally there is no leakage of electrolyte from EFB batteries, which reduces the risk of safety accidents in batteries.
Lower self-discharge rate: Due to the excess electrolyte of EFB battery generally EFB battery power outflow is very little, improving the utilization of energy. Especially in the case of a long time can not be recharged, EFB batteries show a greater advantage over other batteries, but also reduce the number of battery charging in order to extend the service life.
Longer service lifespan: Since EFB batteries are manufactured differently from conventional lead-acid batteries in many ways, the service life of EFB batteries is twice as long as the service life of conventional lead-acid batteries, and it lasts about 4 to 6 years.
Less affected by temperature: EFB batteries have sufficient electrolyte to have better heat resistance. It can work normally under the temperature environment from -30℃ to 80℃, there is no need to fear that the working efficiency of EFB battery will be reduced in winter or summer.
Fast charging speed: EFB battery applies the application of high stability carbon technology in order to improve the conductive ability of the active substance, enhance the battery charging acceptance and fast charging ability.
3. Disadvantages of EFB battery
Strict charging conditions: EFB batteries are easy to overcharge and electronic electrolyte boiling, which requires you to control the degree of charging in the EFB battery charging, but generally EFB battery charging, we have been beside the side of the observation and is unlikely, even if we know that this shortcoming of the EFB battery is not a good solution.
More expensive: EFB batteries use a newer battery technology, and EFB batteries more electrolyte, so it is also more expensive than traditional lead-acid batteries to a high degree of reason. Generally the price of EFB battery is from 50 dollars to 200 dollars.
4. Uses of EFB battery
Start-stop system of automobile: EFB battery is a kind of automobile design battery with start-stop function, in the time of heavy traffic, the automobile needs to restart the engine constantly, EFB battery can handle the start-stop cycle of the automobile. Particularly suitable for the requirements of Asian automakers, there are already Ford models, European cars in many start-stop model applications, equivalent to the general engine compartment are required EFB battery.
Regenerative braking: many electric and hybrid vehicles use regenerative braking to convert the loss of energy into electrical energy again, which can be used for the second time for the car, the use of EFB batteries can be just for regenerative braking to provide fast charging and discharging cycle.
5. Development of EFB battery
Since 2010, EFB batteries have been widely used in Europe, and today about half of European cars have been installed with EFB batteries for electric vehicles. Countries around the world are constantly developing new energy vehicles to make them more convenient and safer. It is believed that EFB batteries will replace AGM batteries in the near future. In the next five years, EFB batteries will replace other batteries in cars with a 20% growth rate in the market. EFB batteries are not only a new type of enhanced liquid-rich batteries, but they are opening up an important market in the automotive field as well as in other fields. The emergence of EFB batteries represents people’s progress towards smarter and more convenient cars and provides a more convenient way of traveling in our daily life.
Conclusion:
EFB batteries are developed to provide us with more convenient transportation, and its many unique advantages are worth choosing it. However, care should be taken to maintain the EFB battery during use in order to prolong the service life of the EFB battery. In the future development, EFB batteries will show more advantages and provide us with more convenience.
FAQ
EFB batteries are better than lithium iron phosphate batteries in terms of price and safety, but they are better than lithium iron phosphate batteries in terms of life span, cycle times, depth of discharge and energy density.
The main brands that make EFB batteries with better quality in the market are Camel batteries, Varta batteries, and Windsurf batteries. Each of these brands has its own characteristics, and when choosing one, you can pick it according to your personal preference, brand history, technology development or salesperson’s recommendation.
EFB batteries are an upgraded version of traditional liquid-rich batteries, which are still liquid-rich in nature, but with a series of improved performance through optimized manufacturing processes. It is applied to start-stop cars.AGM battery is a completely innovative battery with AGM technology, where the electrolyte is completely adsorbed on the spacer. It is widely used in high-end automobiles.
