The solution is as follows: 1, plate vulcanization: mildly vulcanized battery, can be ruled out by the method of small current for a long time charging, vulcanization is more serious then use the method of devulcanization charging to eliminate vulcanization; Batteries with particularly severe vulcanization should be scrapped. 2, active substances fall off: for the active substances fall off the lead battery, if the sediment is less, can be removed and continue to use; If there is more sediment, replace the new plate and electrolyte.

3, plate grid corrosion: corrosion light battery, if there are impurities in the electrolyte, should pour out the electrolyte, and repeatedly clean with distilled water, and then add a new electrolyte, can be used after charging; The battery with more serious corrosion, if the electrolyte density is too high, can be adjusted to the specified value, and continue to use without charging; If the battery is seriously corroded, such as the grid frame is broken, the active material falls off in chunks, etc., the plate needs to be replaced.
