Back in the day, the theory being advanced on the old forum was that US BMW batteries aren't as good as the ones installed by the factory in Germany. The German ones were [then?] made by Varta, and the Interstate replacement I've posted about here some years back was also Varta. I think Interstate switched to their in-house MegaWhatever now, though.
