What size battery for a 1995 G20 van?

Answer 1

Partial Answer by RFXK (2/13/07): Do you mean physical size or cold cranking amps? The physical size is limited by the battery tray in the van. I haven't measured it, but it's not very big, on a qualitative scale call it medium/large. Note that if you get a battery that is physically larger than the tray, you will have to disconnect the wires around the battery area in order to be able to slip it in (it's a pretty tight space), and then you're going to have to figure out some way to secure it on top of the tray; in my opinion, this is not worth it. The rated CCA is (I think) 550 CCA. That doesn't sound all that big either, but I own three G vans and 550 has been perfectly adequate all the way down to zero to 10 degrees. Note that any auto parts store that sells batteries will be able to tell you exactly what you need (that they have). As a general comment, it is ALWAYS worth the extra 20 or 25 bucks to get a top of the line battery (like an Interstate or a Nationwide) versus getting something generic from a chain store. A good battery will cost you about 70 bucks, and it will take you about 30 minutes to do the switch, assuming you have the proper tools and a clue. Hope this helps.
