7 year old BMW 328i battery prices
2008 328i. Typo
About$100.00 + or - most auto parts store's will install it for free. Look for online coupons. Advanced Auto Parts has some great deals online.
As a side note, the battery in the 2006 and up BMW has to be registered or programmed to the vehicle to ensure proper charging. Have an independent BMW shop do this for you. Should cost around $50. See if you can get a quote from the shop to replace the battery as well and save some time and effort.
Thanks for the info There is a BMW shop close by Thanks
