Reasons and preventive measures for zero or low voltage of battery

What is the possible cause of zero or low voltage of the battery?

1. The battery suffers from external short circuit or overcharge and battery over-discharge

2. The battery is continuously overcharged by high magnification and high current, resulting in the expansion of the battery pole core and direct contact with the positive pole for short circuit

3. The leakage current of the protection board is large

4. Short circuit, open circuit and poor connection with plug

5. The battery suffers from external short circuit or overcharge, reverse charge (forced over-discharge);

6. The battery is continuously overcharged by high magnification and high current, resulting in the expansion of the battery pole core and direct contact between the positive and negative poles;

7. Internal short circuit or micro short circuit of battery

8. Internal short circuit or micro short circuit of the battery, such as: burr on the positive and negative pole pieces penetrating the diaphragm paper contact short circuit, improper placement of the positive and negative pole pieces causing the contact short circuit of the pole piece, or short circuit between the positive pole piece and the steel shell, short circuit between the positive pole lug and the negative pole piece, negative powder falling into the diaphragm paper, defects in the diaphragm paper itself, etc.

9. The lead wire and the battery are desoldered and faulty

Measures to prevent zero or low voltage of battery:

1. Check whether the battery has voltage and current;

2. Avoid battery short circuit and pay attention to the positive and negative poles of the charger;

3. Avoid battery collision and heavy pressure;

4. Recharge the battery after it reaches the shutdown voltage, and then stop after it is fully charged.

matters needing attention：

1. Avoid short circuit between metal objects and positive and negative poles

2. Test whether the performance of the charger meets the standard before charging

3. The positive and negative poles of the battery shall not contact with metal objects when placed
