i got a free battery think its dead though. oh well if all else fails i get a core charge. i can dead short this battery with no spark at all and watch the voltage drop to 40mv when shorted. i believe it just got overly sulfated sitting. its sitting at 12 flat but has no capacity. i need any ideas as to how to bring this bish bak for the least $$$ possible.

bakstory guy had a bad batt in his back bank pulled the back batt and this and let this sit for an unknown period of time i recieved it resting at 10.6. it is indeed agm

got a apparently very dead battery for free. im either gonna attempt to desulfate it and use it. or im going to get a core charge out of it. either way win win. so how would you all suggest going about trying to desulfate this battery? keep in mind it is agm. im not drilling any holes into it either. ive done my research id like the communitys' opinions.

and thank you antonio ill look into that.

my current chargers are the poop and id be willing to spend around $100 for the nicest charger possible at that price point. so if anyone has suggestions on some nice chargers that arent going to toast agm batts with crazy voltage and a good desulfation system im open to all options that anyone has personally had good experience with.

It will lose something like 25% storage every 3 months it sits below iirc 11v
So if it was sitting there below 11v for 6 months the very best you can do is bring it back to 50% capacity
And that's if desulfating it works

Recycling is around $.15 a lb
