Re: 1997 328i Cabriolet Battery

[Drew Mouton <drew@xxxxxxxxx>]

In general, the only issues you face with battery selection are draw or 
capacity (CCA - Cold Cranking Amps) and physical dimensions.

Your battery will probably be labelled as 12v, 340A, 75 Ah and 650 CCA - 
with a physical dimension of about 12.5" x 7", and the negative post on 
top surface, the bottom left corner.

When it came time to replace my last battery (in my '98 328i), since I 
wasn't too keen on paying the US$160 price to the dealer for a battery 
with a 1 year warranty, I simply went to the auto parts store (AutoZone) 
to look for something comparable. What I found was a 650 CCA battery that 
was simply 0.5" narrower. (If I could remember the Group number I'd tell 
you, but can't off the top of my head.)

Works great, no difference - and cost was US$55 for a battery with a 5yr 
warranty.
