Just replaced my battery after 12 years as it dropped a cell. I was going to get the DIN55 / 53 instead of getting the usual DIN66 / 65 since the car is getting really old so I probably don't need a battery to last another 12 years.
Ended up getting a exide 54CMF which is $20 cheaper than the DIN55 and has a little bit more capacity. The 940 don't have clearence issue so it doesn't really need the DIN / recessed post battery. DIN batteries used to cost 1/3 more but the price gap is much smaller these days for some brands.
I teste fitted a 55D23L but the positive cable is a bit squashed and the negative is touching the coolant reservoir hose. So went with the 54CMF which is 19mm lower.
Ended up paying $119 as there is a $30 battery trade in promotion at beaurepaires.
