Has anyone successfully rejuvenated any SLA that has become sulphated? There’s lots of info on how to do this on the web ranging from videos to reviews of desulphating chargers. That’s fine and dandy but I’d be interested in hearing from anyone who has recovered an SLA.
I have a number of old SLAs that are somewhat knackered to very knackered. I’ve no intention of using them on an activation partly because I’ve got my feet firmly in the Lithium category now and also because these are my old contesting batteries and they are 4V or 6V 100Ahr cells and weigh around 23kg each!
I’d be happy to see if they can be recovered if anyone has achieved this personally. Failing that it’s time to weigh them in… I wonder how much 112kg of surplus lead is worth?
