Safety tip: Why do rechargeable batteries bulge? What should I do if I encounter this problem?

The only way to read the small part of the story: the bulge in the rechargeable battery may be due to the following reasons

1. Overcharging

Normal rechargeable batteries have an overcharge protection system, mainly for the protection of the battery core, when the battery is charged to the set value of the protection system, it will automatically disconnect. However, in order to increase the durability of the rechargeable battery, some manufacturers do not set the standard value of the protection system, or the rechargeable battery plate protection system is damaged and leads to overcharging, which will easily cause the battery overcharge bulge.

2. Improper choice of charging adapter

The voltage or current of the charging adapter will cause great damage to the battery, which will also cause bulging in the long term.

3. Battery quality problems

Some manufacturers use inferior cells that do not meet national standards in order to save costs.

4. Charging voltage is too high

If the charging voltage is too high, the charging current is high, resulting in accelerated gas precipitation on the positive plate, while the temperature inside the battery increases, and when the pressure reaches a certain level, the battery bulges and deforms.

5. Counterfeit and shoddy rechargeable batteries

Nowadays, there are many brands in the rechargeable battery market. These products either do not protect the circuit board, or cut corners, resulting in poor quality rechargeable batteries, not charged a few times or dozens of times on the bulge damage, so be sure to select a quality manufacturer to buy rechargeable batteries.
