So I've been looking into replacing the 12V battery in my car as it's almost five and a half years old, and I already replaced the main big battery, but I'm having trouble finding a replacement (non-BMW branded) for the additional 12V battery my car has (stacked on top of the big battery). So overall, the ActiveHybrid 3 has 3 batteries.
The smaller one in my car is 40Ah, 480A, 420CCA, 60RC. I don't see any indication of size, but based on my research it may be a "B13"? The part number on there returns a bunch of non-english results for the OEM of the battery (Varta) and has led me down a road to this Bosch:
http://www.bosch-automotive-catalog....uct/0092S40010. Think this one will work? Based on the part number it looks like it has a higher CCA and may be 17mm taller?
