Has anyone tried to recondition a 12v lead acid battery with any sucess? I've seen various methods used from draining and rinsing out to using epsom salts and a higher charge voltage, but do they really make much difference?
I plan to test out my mismatched leisure batteries in a few weeks time, but my car battery has been in poor health for the 5 months that I've owned it though it always starts fine so no great rush to replace it at present but likely will do before winter. Out of interest I emptied out the electrolyte into a clean bucket, and there was some black muck in there! So blasted the cells out with a hosepipe until clear. Then refilled with the same now clear electrolyte which had settled out leaving a thin black gritty layer in the bucket. Well just doing that alone followed by a low charge seemed to make an improvement to the battery, SOH was up from 23% to 37%, capacity from 310Ah to 390Ah, and resistance had dropped from 8.86ohm to 7.07%. Still not exactly great but just wondering if some further method could improve it as all cells seem fine? As said I expect that winter may well kill it off so will likely need replacing but there's no harm in experimenting a bit for now!
Any thoughts?
