1 The battery cannot be charged when the battery cannot charge, can be divided into the following originals: charger to reverse or charger failure; protection board protection does not recover or protect the board fault; battery pack and electricity cutting. Sitting in sequence for the above bad phenomena: The charger is not reversed, the battery pack charging positive and negative plug is reversed; re-enabling the protective board protection, the measuring protective board MOS tube is not a drive voltage; lookup wiring connection Is it loose disconnection?. 2 After the battery pack is used, it will soon be repaired.

This situation has been protected: the lithium ion battery has no charge; the single string voltage capacity is different; the battery pack micro short circuit or battery pack self-discharge The battery pack is just fired. For the above poor, the battery pack can be recharged or replaced with a bad battery. 3 Battery board softening faults should appear as the surface of the positive electrode plate to gradually be soft from the beginning of the solid, and as the surface area is reduced, the battery capacity can be reduced.

Repair method: After discharging 10.5V, light bulb is discharged for 1-5 hours. Then the activator, activation repair.

In this way, it is possible to repair, but in a heavier case, it can only replace new. .
