Equalization
Equalization is a process of controlled battery over-charging. It is used as a routine maintenance activity and a remedial activity for flooded lead acid batteries. It is part of the multi-stage charging process. Lead acid batteries suffer from ''sulfation''. This happens when the sulfuric acid inside the battery cells form tiny crystals on the lead …
