This leaves me with the comfort that the specfications are in line with the batterys actual performance. If you recall there was much prior discussion in this regard - the batteries specs seemed to be inconsistent with its behavior in my car.
Anyway thanks again Harold. The Braille 3121 has my full endorsement for a warm weather M3 application, regardless of the vehicles options.
Lucid: Any update on your installation?
Well, back to square one... The battery now often gets so low in charge that the date and time are lost. I just got back from 2 weeks of vacation (away from the car and it was not started nor used) and now I can not seem to get enough charge in the battery to memorize the date and time. I am going to return the battery and look for something around 60 Ah. I am very puzzled as to why many can have good luck on this exact car in this exact configuration.
