First, fully recharge the cell, and then continue to charge the cell at a C 20 rate for five to seven hours. During equalization charges, the cell voltage will become very high, about 2.7 VDC per cell. This overcharge contains the necessary power to break up the smaller lead sulfate crystals and return these sulfate ions into solution in the electrolyte. The larger sulfate crystals, however, cannot be broken up even by an equalizing charge. If a sulfate bond spends several...
