Can anyone with ACTUAL BMW Maintenance experience answer if it is crucial that you buy an exact replacement battery. For example, I have an 2007 335xi that badly needs a new battery, the current battery is a 12V 90 Ah 720 A 720 CCA 160 RC (pictured), do I have to get a battery with those exact specs? Auto Zone and O'Reilly's both say they have a battery for it. I don't care so much about the cost, I'm gonna have an Indy shop register the battery once I replace it. I just want someone who is smart on this matter to help me out. I don't want to sound rude but some of these threads are just full of BS, know what I mean? Thanks for the help guys!
