Post Subject: 12 Volts Lead Acid Battery DesulfatorThere are relatively inexpensive "desulfators" which claim to be able to restore LA batteries. I believe that they store a capacitive charge and quickly pulse the battery with an reverse polarity voltage to encourage the lead salts to return a chargeable solution. I had one of these on a very pricey 48VDC forklift battery and they seemed to be helpful. I don't see them mentioned in subscribers questions or sold in the UK and they may not be 'allowed'....but do they work at 12VDC?
