ok bear with me please.
I have looked at whats in the car now and found it to say
I think this is fairly common for the 325i
At AutoZone and Sears I've asked about batteries on the car and both seemed baffled and offered several batteries not knowing which I "needed". None of what either offered were 570A/CCA. The offered much more. (this is the bear with me part) I know very little about batteries so can I/should I get a higher "rated?" battery? Or anyone who had that battery wanna just tell me what to get?
