AGM battery
WARNING: This page is about a different car, the 2013 BMW X5, 2012 BMW X5, and 2011 BMW X5. 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.
IMPORTANT:
Observe installation instructions for AGM battery!
In all cases, an AGM battery must be installed and registered in the vehicle for the MSA to work perfectly.
