Reasons for Easy Damage of Maintenance-Free Panasonic Battery

1. Contamination deposited on the upper and lower parts of the plate causes short circuit.

2. The deformation of the electrode plate results in the contact between the positive plate and the cladding plate, which results in short circuit.

3. Overdischarge, the discharge protection circuit of UPS power supply is abnormal, and the load of UPS power supply is too small to form deep discharge of battery.

4. Panasonic batteries will fail if they are not charged or overcharged for a long time.

5. Charging with unqualified chargers, some chargers have no current limiting devices, resulting in battery damage.

6. There is no electrolyte. It has been used for a long time. The electrolyte can be replenished once a year.

7. The proportion of electrolyte is too high.

8. Charging at high temperature, Panasonic lead-acid batteries have been improved continuously, and their protection rate is relatively low in the process of operation. However, users must not neglect management because of its "protection-free" nature.

Some simple inspection and protection is still necessary, so as to better ensure the use of batteries.
