its a honda crx with the small group 51 battery in the stock location. I have found 2 batteries that will fit the stock tray. The powermaster xs series, and the optima yellow top. Which is a better battery for spl? Both are rated at 12 volts

 

I'm a big fan of the Powermaster XS series -- work very well for me.

 

go for the powermaster 3100 or a odyssey 2150

 

^^
