Does anyone know of a good battery reconditioning guide?

[Peter Rosenfeldt]

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

Let me know if you find a way that actually works Peter!
I don't know of anything that reconditions old batteries. Could be that recoverability depends on the failure mode: If the battery was good but left to sulphate badly it may just be possible to undo this. But if there's nothing left on the positive plates I don't see how it would ever recover.

I second what Rob says.
Golf cart (T105) batteries are cheap, relative to full renewable energy batteries. Better to start with some inexpensive new ones. My premium set that lived off grid most of their lives were worn out, when charging the electrolyte temp would approach 50deg C when absorbing. High resistance, sulfated, 15 years old.

Go new or expect a dissapointing experience
