I always look for a battery that will fit in the spot it has to go and has the posts on the ends they need to be to connect it.

It's a class 26. I don't remember which one, as the 26R or the 26 is the correct one. They just have the poles on the opposite side of the battery and vice-versa. You'll have to know which end you want toward the front, the + or the - . HTHs

I use the 526RMF Deka Batteries in any of my 12V conversions on my Tractors. Fits in the box nice and sports about 540 CCA's.
