I have the following 12V car battery: Varta Silver Dynamic AGM 595901085 (12V/95Ah/850A), and the following car: Jaguar S-Type 2.7D.
In the technical cars manual it says this:
So in cold winter mornings, when I initially start the car, the alternator is charging the battery with with 15.5V.
Is this safe for the battery?
Varta recommends charging it with up to 14.8V (according to what I found on their website).
