I have read that the battery can be either Group 94R or Group 49. I will have to look and see which battery is in my M3.
EDIT: battery is part number 61212353810 720CCA 90AH. It is over 13" long so I am pretty sure it is an H8/49 style. Crappy Tire has them in stock (UltraAGM M8). Likely pick one up this eve and swap it out. It is a real PITA trying to figure out BMW's part numbers for this battery. Grr - if you try to figure out the BMW part number for the M3 now, it is tedious. This is as close as I could get after a trip down the rabbit hole: 61217586962 and this is the NON-AGM version. Not sure why I wasted my time but meh, nothing better to do.
Cheers,
