Battery Spec
Anyone know the OEM battery spec or can point me in the right direction, looking at lightweight alternatives and want to know which to get!
Also, anyone know the weight of the standard one? |

I actually just changed mine yesterday, went for OEM and have the old one lying in the garage. If I remember, I'll weigh it later on this afternoon for ya. It's a heavy yoke, but when I looked at my mates 80Ah one in his M3, she's tiny compared to that bad boy.

Just got myself a OEM, too.
Looking forward to get a lightweight from BMW, like Porsche developed. Just a little expensive!! 2'k

Users of the 18Ah battery should notice no difference in performance when compared to the 60Ah Lead battery. The reason for this is that lead battery users normally get the benefit of just 30% of the battery at any given time, versus the 100% available power of the Li-ion version. Purchasers of the 911 GT3, 911 GT 3 RS, and the Boxster Spyder will be able to get the lightweight battery as an option. German pricing for the battery is an astonishingly high €1,904, including VAT. As if that is not bad enough, previous purchasers of those three models can retrofit the battery for €2,499, beginning in February.
