What to do if the cell phone battery is swelling

Battery swelling and short circuit are two different things. Bumps do not necessarily have safety risks, but short circuits can cause combustion and explosion. However, it must be noted that to a certain extent, battery packs may also have potential risks. When there is a bulge, as long as you stop charging and using it in time, it is basically safe.

Let’s first understand the mechanism of battery bulging. In simple terms, battery bulging is due to the reaction of the battery electrolyte, which generates a large amount of hydrogen, carbon dioxide and alkane compounds, squeezing the battery case, and making the battery case swell.

The main reasons for generating gas are the following: the battery is overcharged, the battery is overdischarged, the battery is affected by high temperature, the battery is used for a long time, the battery has a design defect, and other unexpected conditions (such as welding Glitches pierce the surface of the battery, etc.).

How to avoid battery bulging?

1. Don’t charge for too long;

2.Use the original charger;

3.Keep the charging environment dry and cool, and avoid charging in high temperature, hot and humid environments.

What should we do when we find that the battery is bulging?

1.Be careful to avoid squeezing or puncturing the swollen battery, and prevent short circuit;

2. Suspend the use of damaged mobile phones and put them in a safe place to prevent serious incidents;

3.Contact the manufacturer for handling, whether it is after-sales or replacement, and coordinate with the manufacturer;

4.If the mobile phone is out of warranty, please don’t discard the drum battery directly, contact the battery recycling manufacturer for proper disposal.
