I am assuming you changed it to 12 volt, otherwise a group 1 6 volt is about your only choice. If you have changed to 12 volt, go to this web site http://www.rtpnet.org/~teaa/bcigroup.html and find the closest bci go group size to the group one which as towards the bottom of the page. Then go to the 12 volt batteries and see which one is dimensionaly close to the group 1. You will find you are rather limited as to what will fit. However almost any battery will turn it. Find the group size that will fit, and buy the largest CCA you can afford. A group 22 is a popular choice.
