Summarize the battery repair (no big capacity, or more than 70% of the nominal capacity):
1, the battery positive plate is softened, and its significant performance is to find black impurities in the absorption of excess electrolytes. If the black impurities are more, it is the softening of the positive electrode plate, so that the battery is substantially unhappy, only scrapped.
2, battery vulcanization. It is recommended that the battery is pulsed and repaired again.
3, 30 minutes after charging, test the battery voltage, still less than 12V, may be the internal disconnection of the battery. The battery should be scrapped.
