AGM battery
The automatic engine start-stop is used with the intelligent generator control (IGR). The much more frequent charging and discharging means that the load on the battery is very high.
The cycle resistance of AGM batteries means that they achieve similar results to conventional batteries with regard to service life despite the high load.
An AGM battery is a lead-acid battery. As compared to the conventional battery, the AGM battery has a glass-fibre fleece as a separator in which the electrolyte is fully absorbed. The AGM battery has a gas tight housing with pressure relief valve.
