Customer Reviews

5 Stars
I received & installed your battery in my generator. The battery went in after loosening & tightening the gas tank a little. Too bad Generac didn't have an easier "slide in & out" battery replacement system. Maybe they'll read my review & correct this. It was easy, though. So far the battery performs as advertised. Appreciated the great price & quick mailing.
