My battery is 5 years old - I want to change it before it breaks downs or starts to damage the starting/charging systems. What's recommended? Which is the best battery you guys have used? Also, what are the battery specs I should be looking at? I have a 85 190E 2.3 - the owners manual says it should be 55 Amp-hrs, which converts to an RC rating of 137.5, but doesn't say anything about the min CCA (The winters in Cleveland can get a little cold!).

Tried looking up in search but couldn't find much. Thanks for your responses.
