Customer Reviews


The battery was just what i was looking for..light and powerfull..


I'm giving this a 2 because of ad fraud. have a 09 King and the + terminal needed to be on right side, which this photo shows. Even the box has the terminal on the right side, IT ISN'T. If I.m Paying $300+ for a battery that's supposed to fit, I am not adding and rerouting wire to make it fit.They are suppose to be sending the right one, but waiting 4 weeks to get the proper one sucks.


Ultra fast cranking with my cvo and its light weight made for easy installation. Highly recommended over all other batteries I've used since 1974 in my scooters.
