If the battery in your MacBook, or any other device, begins to grow or bulge, don’t ignore it. Consider it seriously. It indicates a problem with the battery, and if you continue to use and charge it, the consequence might be a fire or an explosion. It will very certainly overheat and harm your PC.

Why do MacBook batteries get Swollen?

The most common reason for a swollen MacBook battery is overcharging. When a battery is overcharged, it produces excess heat, which can cause the battery to swell.

Another reason for a swollen MacBook battery is a manufacturing defect. In some cases, the battery cells are not properly sealed, which can allow excess pressure to build up inside the battery, causing it to swell.

If your MacBook battery is swollen, it is important to have it replaced as soon as possible. A swollen battery can cause the battery to catch fire or explode, which can be very dangerous.
