What is the Difference Between EFB Battery and Ordinary Battery?

1. EFB battery is an enhanced flooded battery, which belongs to start-stop battery, and its lifespan is 3 times that of ordinary batteries


Contrary to the liquid-poor battery, the remaining space in the battery tank after removing the pole plates, separators and other solid assembly components is completely filled with electrolyte. During the use of the enhanced flooded battery, the density of the electrolyte changes due to the loss of evaporation and decomposition of water, so the battery closure cover of the EFB battery is a movable battery cover, which is used to add distilled water to adjust the concentration of the electrolyte.


2. The internal structure and performance of EFB batteries are different from ordinary batteries.


EFB battery is a flooded battery, which can add distilled water to adjust the concentration of the electrolyte. The battery is a very important part of the car. When the engine is not started, the battery powers the electronic equipment of the whole car, and the battery is also responsible for starting the engine. After starting the engine, it is the alternator that supplies power to the entire car's electronics. The alternator also charges the battery after starting the engine. The battery is a wearing part in the car, and this part needs to be replaced regularly.


Most cars use ordinary maintenance-free batteries, which cannot be disassembled. If the performance fails, the entire battery must be replaced. Some German cars use AGM batteries, which is also a well-known battery. However, the AGM battery is not resistant to high temperature, and this kind of battery is not suitable for use in the engine compartment with relatively high temperature. The car battery EFB has better high temperature resistance, and this kind of battery is more suitable for use in the engine compartment. The charging and discharging principle of the battery is very simple. The positive electrode and the negative electrode of the battery are made of two metals with different reactivity, and the electrolyte between the positive electrode and the negative electrode is both. The battery life of the car is also closely related to the owner's usage habits. If the usage habits are not good, it will reduce the battery life.


3. The process of EFB battery is different from that of ordinary battery


The EFB start-stop battery can adjust the electrolyte concentration by adding distilled water to improve the cycle performance of the battery. EFB batteries have good high temperature resistance and are suitable for use in engine compartments. It can completely meet the standard of the start-stop system, and the performance is three times higher than that of ordinary batteries. The cost performance is very high, and it is more than twice as expensive as ordinary batteries. EFB batteries have low self-discharge and long service life. The battery life can be up to 3 to 5 years. At the same time, the EFB battery adopts a new process, and the low-temperature starting current has a greater improvement than that of ordinary batteries. The life of ordinary batteries is generally 2 to 3 years. After this period of time, the car owner pays special attention to the maintenance of the battery, and replaces it in time if necessary, so as not to affect the vehicle.
