Avoid subjecting the battery to physical stress, such as vibration or impact. This can increase the risk of explosion.
What to Do if You Have a Swollen Battery
If you have a swollen battery, it’s essential to take action. Here are some steps you can follow:
Disconnect the Battery
If the battery is still connected to a device, disconnect it immediately. This will reduce the risk of electrical shorts and explosion.
Contact the Manufacturer
Reach out to the manufacturer for guidance. They may be able to provide advice on how to safely dispose of the battery or repair it.
Dispose of the Battery Safely
If the battery is no longer usable, dispose of it safely. Take it to a recycling center or a hazardous waste facility.
Conclusion
A swollen battery can be a serious safety risk, and the possibility of explosion is still present even if it’s not plugged in. However, by understanding the causes of swelling and taking steps to reduce the risk of explosion, you can stay safe. Remember to store the battery safely, monitor its temperature, and avoid physical stress. If you have a swollen battery, disconnect it, contact the manufacturer, and dispose of it safely.

What causes a swollen battery to explode?
A swollen battery explosion is often caused by the buildup of gases inside the battery, which can lead to increased pressure and potentially cause the battery to rupture. This buildup of gases can be the result of a variety of factors, including overcharging, high temperatures, or physical damage to the battery.
When a battery is overcharged, the excess energy can cause the chemicals inside the battery to break down and release gases. Similarly, high temperatures can cause the chemicals to degrade and release gases. Physical damage to the battery can also cause the internal chemicals to leak and react with the air, leading to the buildup of gases. In all of these cases, the increased pressure can cause the battery to swell and potentially lead to an explosion.
How common are swollen battery explosions?
Swollen battery explosions are relatively rare, but they can and do occur. While the exact frequency of swollen battery explosions is difficult to determine, there have been several high-profile cases in recent years.
