What does the Over-charge affect the battery performance?

- Dec 21, 2018-

"Over-charge" is described as a continuous charge action after the battery has been fully charged by a certain charge method. Since the capacity level from positive polarity is higher than the negative polarity, the positive polarity will generate Oxygen, which can be composed with the Cadmium generated from negative polarity via separator. In general condition, the internal pressure will not increase significantly, however, if the charging-current applied for battery is too much, the charging-time is extremely long and finally the Oxygen could not be used up in time, the battery will be defected by a pressure risen, battery distortion, leakage and so on. Definitely the battery's performance will decline as well .
