PURPOSE:To make it possible to suppress, as small as possible, any deterioration in the performance of a plate immediately use during preservation thereof and improve its quality by making electric charge again after potential of a cathode plate reaches that of PbO2/PbSO4 when a circuit is opened after continuous current flow. CONSTITUTION:A higher grade oxide whose electrical potential is lower than that of PbO2/PbSO4 is formed when a circuit is closed for continuous current flow, and a battery is charged again after a cathode potential reaches that of PbO2/PbSO4 when the circuit is opened. There is a potential region of another higher grade oxide until the potential of the plate is attenuated from the potential where oxygen is generated to that of PbO2/PbSO4 with the circuit opened after flow of current. There is a potential region of that higher grade oxide and it is the borderline where characteristics of a plate are changed. Therefore, the performance of the plate deteriorated during its preservation can be suppressed by destroying the higher grade oxide thoroughly. |
