The battery in my car is 61217553951 "See SI 610696 (110)" 70AH 760CCA

I call my dealer and they suggest 61217586961 80AH 640CCA



The oem '951' battery is apparently not available. It seems odd that they would replace it with a lower rated battery. The parts guy claims that the newer 961 is what they use on the e90, and is a lower rated battery. He basically suggested I keep looking and fine a 760cca battery....


Thoughts? I know 12v is 12v, I know I can go aftermarket but in general I prefer to stick with BMW parts. However, I don't really want to put in a lower rated battery.

Can someone lookup "SI 610696 (110)" ? Google did not help.
