[QUOTE="Tathradj, post: 584255, member: 2436"] Put yur multi meter on 20v. Black on earth terminal, Start by dipping your probe in each cell. Yes, Into the acid. Measure each cell back to earth then do the same from the positive side. If each cell comes up with the same voltage, You will be able to recover it. If one drops right out, You either have a shorted or completely dead cell. May explode or do nothing. Reason why is the plates have [u][i]formed a sulphate crust over them and will not conduct. [/i][/u] A transformer charger of about 4 amps for a week will work. I have just recovered a battery of mine by putting some epson salts disolved in warmed demineralised water and trickle charging for a week. This applies for lead acid batteries only. If you do not know the dangers involved with this type of battery, Please do not go there. [/QUOTE]
