This is all interesting stuff. So far my 4 year old original battery is holding up well, but I'm not expecting many more winters from it.
Do any of you guys know the weight difference between the AGM vs lead acid batteries?
Anyone know if the BMWhat battery registration is capable to change battery types if one switches from what was originally in the car?
