2004 X5 4.4 Battery replacement
 

Does the Bosch battery from Pep Boys switch right out with the original? BMW said they only warranty their batteries for two years. What's up with that?

Thanks all!!

go get you one at autozone for $160.00 + it come with free 4 years replacement. ( just tell them what you need and they will match the right side for you)

Pepboy sells the Group 49 battery for the 4.4L and it cost apx 100 (plus core).

:iagree: the G49 Bosch battery is nice

The Bosch battery is made by Exide (Autolite for Kragen/O'Reilly), who also happens to make DieHard batteries. Get what you like, but they are basically the same battery. I have to agree that the Autozone Duralast have a much better warranty.

I bought mine from Pep Boys, was around $100 and at the time there was a mail in rebate for $10 or $20, it works well for me.
