Well my tired stock battery is finally letting go and I know this topic has floated around the forums on several occasions. I have boiled it down to the Sears PM series but my question is what is the differences in the Auto PM's and the Marine PM's? Is it just the CCA?

Thanks

 

Yes, the Marine series is a more HD battery. If you get the PM-1 you'll need to extend the ground cable.

 

Thanks, I figured there would be more work involved.....lol
