LOL
anyways cant complain cause the newer battery for 2012-2013 cost around $510 its weird how every year has different battery part number.
For those looking to shed some pounds, use either the Z4 or MINI battery on our website. They bolt into the stock location and work perfectly.
For those needing the additional CCAs (extreme cold or lots of gadgets), stick with the OEM size.
