..Group 31 battery, got low...wouldn't start the combine so I pulled it off and have it on the charger. Charger will put out 40 amps on a fast charge, and 5 out of 6 cells will bubble. Turn it to boost for a few seconds and it will immediately bubble on all 6 cells. Seems like #1 cell is sulphated...but will it come clean and take a charge eventually if I just leave it on a fast charge?
Let it sit for 24 hrs, then check voltage. It should read atleast 12V (low state of charge) up to 12.;8 which is a full charged 12V battery. If it reads 10V, one cell is shorted and dead, nothing will fix a shorted cell. If it reads atleast 12V, slow charge(2 amps) it for 2-3 days to break sulfation. Your chances of reversing sulfation is better if you can use a charger with a desulphator mode. Continuing on high charge rate will wreck the other 5 cells while trying to restore the bad one. |
Can this battery be saved?
