I ask this question, because all four of my local BMW dealerships parts places gave me different information. Some say it is 65 amps/540 cold cranking amps. Others say 70/540, 50/450, 50/265. But I need to know so I get the right battery.
What is the amp and cold cranking amp for the battery this car? on 1990 BMW 325i
i'm not sure why your getting so many different answers, but the correct battery is a group 91 w/ 600 cold cranking amps.
