　　The cause of the inductance of polar plate irreversible sulfuric acid is classified as follows:

　　(1) The storage time is too long, the self -discharge rate is high, and it is not maintained and charged.

　　(2) No timely charging it after discharge.

　　(3) It is in a state of owed charging for a long time.

　　(4) Discharge.

　　(5) The concentration of drying or adding electrolytes is too high.

　　When the battery generates irreversible sulfate, it should be repaired according to its level of severity.

　　Those with lighter salt can be renovated normally to return to normal activation charging (that is, balanced charging) to return to normal. The specific method is as follows:

　　Constant voltage limit charging: The first stage is 0.18C2A charging to 2.7V/single charging for 12-24 hours.

　　The first phase of Hengli Electric: 0.18C2A is charged to 2.4V/single, the second stage: 0.05C2A charging for 5-12 hours.

　　Those with heavy saltization need to be charged and discharged on it to return to normal. The specific method is to add pure water or density to the battery to 1.05g/cm3 dilute sulfuric acid to a rich liquid state, and then charge for about 20 hours with a current of 0.05-0.018c2A, draw the liquid, and then perform a capacity test. Repeat the above operation until the battery capacity is restored.
