From my reading, it depends on the failure mode. If fails from over cycling (heavy discharge / recharge, the active material falls of the plates and shorts out plates (goes low impedance, depending on separator design). High current might clear the first wee shorts, and give more joy for a while. If over-discharged, left flat, undercharged, can sulfate (goes high impedance?). Possible that's what the epsom salts does, is rearrange the ions after that's happened? Of interest, I was going to measure between the plates, but couldn't get both probes in one holw. I did however get a reading as soon as the probes were in the fluid (from cell to cell), 2V, 2V, 2V, 2V, 1.2V So I know which end is faulty, just not which of those two cells, or which failure mode. I may make up some skinny probes to get a better measure. Oh, and Pulse charger: 6 Quote Link to comment Share on other sites More sharing options...
igor Posted March 17, 2022 Share Posted March 17, 2022 Should the one dodgy cell not give you the same low reading when paired with any other cell? Quote Link to comment Share on other sites More sharing options...

h4nd Posted March 19, 2022 Share Posted March 19, 2022 CTEK gave it a go, didn't think it was sulphated, charged it, then thought it was toast. Epsom salts next. 1 Quote Link to comment Share on other sites More sharing options...

I'll give it another try, (after 1/2 tablespoon of Epsom salts). But it's busy having a go at a motobatt AGM bike battery, which it seems to think is sulphated, so ... fingers crossed. 2 Quote Link to comment Share on other sites More sharing options...
