Remember when everything was Big! Anyways I have an old 12v lead acid battery from a big old spot light. The spotlights basically a hand held car headlight . I had lots of fun with it and It's been in storage for a few years. I'd like to revive the batt if possible. Can I still bring the battery back?
if it’s dry there’s likely no coming back from that. No question you will have severe capacity loss and it probably won’t hold voltage well under a large load. try shaking it can you hear stuff moving around? usually you can hear the matting broken up inside there. A good sign of a dry, dead battery. I would say it isn’t worth it personally. But, any automatic charger isn’t going to charge that. I know the NOCO genius chargers have a manual setting. Forcing a charge upon the battery. Just don’t let the alligator clips touch or you will be needing a new auto fuse.
