Question 1: What are the biggest advantages of EFB and AGM

AGM battery refers to the battery whose partition is made of ultra-fine glass wool material. At present, German department and American department mainly promote AGM technology. Compared with ordinary batteries, they are slightly more expensive, but they still have advantages:

(1) The cyclic charging capacity is 3 times higher than that of lead-calcium batteries, Long life and durable.

(2) Higher capacity stability throughout the service life (about three years) cycle.

(3) Low temperature starting is more reliable.

(4) Reduce accident risk, no acid leakage to reduce environmental pollution.

EFB battery is a liquid-rich enhanced start-stop battery, which is developed on the basis of the original ordinary lead-acid battery. It can withstand high temperature and can be installed in the engine compartment, which can fully meet the requirements of the start-stop system. The life performance of EFB battery is three times higher than that of ordinary battery.At present, Japanese manufacturers mainly promote EFB technology.

Question 2: Will the EFB battery self-discharge?

Even if the battery is not connected to an external circuit to discharge, it will slowly lose power itself, a phenomenon called “self-discharge”. The active substance mass of EFB battery is more than that of ordinary battery, and the self-discharge is faster.

Question 3: How to maintain and maintain EFB batteries

1. Regular replenishment of electricity (once /3 months);

2. First in, first out

Question 4: How to replenish the EFB battery?

When charging, there are usually two ways to recharge the battery.

1. Constant current charging (i.e. constant current charging, recommended) : according to the open circuit voltage, specific gravity (20℃), corresponding to the following table for supplementary electricity.

Note: Pay attention to control the time of replenishment when using this method to prevent the battery from overcharging.

2. Constant voltage charging (i.e. constant voltage current limiting charging).

Exhaust type with a fixed voltage of 16.0V, limited current of 2.5× conventional charging current, charging for 16 hours.

Note: The battery voltage may be inflated after this method is used to replenish the power. Therefore, after the battery is charged and left for 4 hours, the measured voltage value will be more accurate.

Question 5: What are the precautions for loading EFB batteries?

1. Slow current charging for 15 minutes before loading;

2, can start the vehicle;

3. Can start the start-stop system.

Question 6: Can start-stop batteries and ordinary batteries be intersubstituted? How long can the life estimate be used to replace the start-stop battery with ordinary battery?

The battery of a start-stop system vehicle cannot be replaced by a normal battery. Because the performance of start-stop batteries is designed to be higher than that of ordinary batteries, the service life of ordinary batteries will decrease. And the battery of the ordinary high-end vehicle can be replaced by the start-stop battery. At the same time in this reminder, the replacement of the battery had better not power!
