AGM battery refers to the battery separator is made of superfine glass wool material. At present, German and American cars mainly promote AGM technology batteries. Compared with ordinary lead-acid battery, AGM Start-Stop battery price is more than three times more expensive, but it has the following advantages:
(1) Cycle charging capacity is 3 times higher than ordinary lead-acid battery, with longer service life.
(2) AGM auto battery has higher capacitance stability throughout the service life cycle.
(3) Low temperature starting is more reliable.
(4) Reduce accident risk, no acid leakage to reduce environmental pollution.
AGM stop-start car battery is not resistant to high temperature and generally cannot be installed in the engine compartment. Therefore, The high temperature resistance of EFB makes it suitable for Japanese and Korean cars with batteries placed next to the engine.
AGM batteries are mostly assembled in European brand vehicles, while EFB batteries are mostly assembled in Japanese brand vehicles. In the use of each has its strengths, there are many battery customers will consult, no car with start and stop function can be replaced by ordinary batteries?
Most of the people who consult this kind of problem come across high-end cars such as Mercedes, BMW and Audi. Take Mercedes Benz for example, many models of Mercedes Benz S series do not have the start-stop function, can we use ordinary battery instead? The answer is "no".
Benz S series, ML series, GL series are basically all AGM auto batteries ranging from 70A to 95A, although S series does not have the start-stop function, but he has vehicular appliances such as refrigerators, coffee heaters, backseat DVD movies and other needs to power, using ordinary batteries is different, the battery industry has tested using ordinary batteries instead of AGM batteries, It ended up being scrapped in 3-6 months.
Compared with Start-Stop EFB batteries, AGM batteries have more excellent deep cycle characteristics, which can meet the application requirements of vehicles with start-stop system, energy recovery system and high-end luxury cars. EFB Start-Stop battery has the characteristics of low cost, wide temperature range and so on, and the overall performance can meet the needs of the entry-level start-stop system.
