Why do Dell laptop battery swell?

Swelling of laptop batteries is not unique to the dell brand. Its common on most devices using Lithium ion polymer batteries to swell.

This is due to either being over charged, heat or slow degradation as the battery ages. The Lithium Ion polymer batteries are not as stable as the previously used Nickel Cadmium (Ni-Cd),
Nickel Metal Hydride (Ni-MH) batteries.

Lithium is more reactive and the fact that the batteries are compacted together does not help the situation. They are pressurized and designed to contain any reactions that happen. This cause them to swell when overheated since contents cannot escape. While this is designed to prevent fire or leakages the swelling can physically damage your computer.

Even if it fits, it does not mean it belongs there. Over charging can happen with the wrong charger.

Is your battery old?

Is it no longer holding charger? If yes whats the point of having a battery that no longer holds a charg. Get rid of it and find a replacement.

The older the battery the more issues it will have.

Lastly do not always leave your laptop charging all the time. I know it can be annoying to plug in your laptop on and off but the battery is there also to work.

Keeping the laptop charging all the time is not wise.
