Hi there

I have a bunch of old golf-cart batteries that I want to recondition to build my own solar installation and when I did some research I keep coming up with a crowd called "EZ battery reconditioning", after sitting through an endless sales video that essentially tells you nothing you get asked to pay $49 for their program which isn't going to happen. I don't mind paying put the claims they make in the video like "you'll get your batteries back to 100% of their original output" are clearly nonsense. Can anyone point me in the right direction here, please?

Regards
Peter
