Not sure if the is the correct area to post.
Purchased a brand new battery from the dealer and removed the protective seal on the positive terminal. Didn't need a battery after all. I can't return it now.
Brand new, $150 firm. I paid $210 for the damn thing. My loss, your gain.
Located in San Mateo, CA, but available in Mountain View during the weekdays.
Baterry PN 61-21-6-946-334, works on an E60 too.
