Hello folks,
im trying to rejuvenate a battery and could do with a little advice please. I have a couple of battery's on long term storage, I have been cycling them every couple of moths or so but the one I want to use is not having it . I have 10v overall with about 8v closet to the positive post working towards the neg post the individual voltages are getting less to the point where the two closest to the neg post a .4v and .3v respectively .
So I decided to put a bulb on across it until the battery was nearly flat and then put it on a trickle charge but what's happening now is the 4 cells working away from the positive post are bubbling gently, but the two that had .4/.3v are doing nothing. This obviously the problem but what can a do to get them back ? There's plenty of stuff about tipping some epon salts into cells on YouTube but dose it really work ? Or should I continue to cycle the battery in the hope it desulphate and come back ?
As ever your thoughts would be appreicited
