Original battery
first off, If this has been answered, Im sorry and would love a link to that thread. I have seen a lot of "Battery" posts but haven't found one to answer the question of how to find out what battery came in my car originally. It seems that these cars are very sensitive when it comes to electrical things. I have a 2008 335i E90 that I bought used. The battery is failing and Im not sure the battery that is in the car is correct and Id like to go back to what came in the car. How do I find that info? If it was a H6, H7, H8 etc. It seems they came with different batteries and I cant just get a "BMW 335i battery". If I cant find out what battery came in the car, can I just get a battery the says it will work for my car (from auto parts store) and code and register that? How exact a match do i need to the factory battery.
