AGM battery

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2016 MINI Cooper Countryman, 2015 MINI Cooper Countryman, 2014 MINI Cooper Countryman, 2013 MINI Cooper, and 2012 MINI Cooper. However, it is still accessible from the selected car via links, so may be relevant.

In all cases, the MSA comes with the intelligent generator control. The much more frequent charge and discharge cycles mean that the load on the battery is very high. The cycle resistance of AGM batteries means that they achieve similar results with regard to service life despite the high load.

In all cases, an AGM battery must be installed and registered in the vehicle for the MSA to work perfectly.
