sascha 17 Report post Posted August 2, 2013 I'm just about to head off to supercheap to buy a new battery for my old man's e46 318i touring, and I thought I'd quickly check if anyone had any particular recommendations for ideal replacements? The current battery is original BMW, part number 90 60 0 305 136 and is rated at 55ah and 480CCA. Am I right to think that as long as I get a battery with at least the same amp hours and cold cranking amps ratings, it'll be fine (and similar dimensions, terminals on the same side, etc)?
