Why does the battery zero voltage appear?
- Aug 25, 2018 -

Why is there a zero voltage in the battery?

1) The battery suffers from external short circuit or over discharge, reverse charge (positive or negative battery or reverse connection); whether the electrical circuit is normal; whether the spot welding battery has burnt marks.

2) The battery is continuously overcharged by high current and large current, causing the battery movement to expand, and the internal positive and negative electrodes are directly in contact with the short circuit.

Approach:

1) Understand the specific use of the battery;

2) After the same type of battery is charged, the appliance is connected to determine whether the appliance is normal;

3) Charge the battery for 1 minute at 1C current, and leave it open for about 10 minutes. If the open circuit voltage of the battery is stable within the normal voltage range of the battery, the battery can basically return to normal. If the battery has been damaged, the voltage cannot be recovered. If the battery does not use this phenomenon, the 1C charging voltage cannot be recovered, and it needs further analysis by professional technicians.

4) It is recommended to use a battery with protective electronic components such as fuses and temperature switches or integrated circuits.
