Any thoughts on if this will be OK? Would it be worth getting something closer to stock if this isn't close enough?
It is not an AGM battery as far as I can tell. It seems from the looking that I have done that there are two sizes that are factory fits, the Group 48 lead acid or H6 AGM and the Group 49 lead acid or H8 AGM. The difference is 41 lbs weight versus 58 lbs weight plus some cranking and reserve capacity. I am battery shopping also for my 08M3, and will go with AGM technology.
