Quick check on BMW's website shows like $800 for an OEM battery which seems high (though looking at the NAPA site they're not that much cheaper).
What brands of batteries do ppl like, or should I go with the OEM one even if it's more?
EDIT: Hm, looks like I need to register the new battery to the car. Looks like there's an app for that kind of thing, seems simple enough but maybe I should let someone else take responsibility for paying if they mess it up...

i own a shop that works on European vehicles, yes the battery will need to be registered once you put a new one in. You definitely don't need the OEM BMW battery any good quality AGM that matches BMW spec should be fine. We use Diehard and have had good luck and they have a good warranty
