Desulfating with Harbor Freight charger

A normal response after juicing it with 6.7 amperes!
Equalizing means to make equal. All six cells. All returned to original equipment specification density. Let's call it 1.280 because that's what it probably is.
IF THE BATTERY IS SULFATED yes it is worth continuing at this setting. You are probably asking yourself "How do I get that voltage to the baby bear ideal setting?" High is too high and low is slow.
This is where that VARIAC I wrote about comes into play. Either set the charger on 12 volts "High" and tweak the VARIAC back to make the charger put out 3 amps or switch it to the 2 amp setting and spin the VARIAC dial up to make 3 amps.
But you can equalize at the one point one amp setting. If the cells are badly sulfated it's going to take a couple of days to dissolve the hardened crystals back into solution.
But without a hydrometer you are flying totally blind. Got a question for you if I may: What made you believe that the cell gravity did not return to OEM density after charging the battery normally?
