Common faults and solutions for batteries!

　　Common faults and solutions for batteries!

　　1. Battery leakage

　　Common night leakage phenomenon:

　　One is poor sealing between the upper cover and the bottom groove or cracking of the sealing adhesive due to collision, and the other is acid leakage from the safety valve; Acid leakage at the three terminals; Four other parts show acid leakage.

　　Inspection and handling methods:

　　Conduct an appearance inspection first to identify the area of acid leakage. Remove the cover to check for signs of acid leakage around the safety valve, and then open the safety valve to check for flowing electrolyte inside the battery. After completing the above work, if no abnormalities are found, an air tightness check should be carried out (add water to inflate and pressurize the battery, observe if there are any bubbles appearing and emitting, and if there are bubbles, it indicates acid leakage). Finally, during the charging process, observe if there is any flowing electrolyte present. If there is, it indicates that it is due to production reasons. During the charging process, any flowing electrolyte should be drained.

　　2. Deformation

　　Fault phenomenon

　　The deformation of a battery is not sudden, but often occurs through a process. The battery enters the high voltage charging zone when charged to about 80% of its capacity. At this point, oxygen is first released from the positive electrode, which passes through the hole in the separator and reaches the negative electrode. Oxygen reactivation reaction on the negative electrode plate:

　　2Pb+O2=2PbO+H2O+Q
