You face real dangers when you ignore the risks of swollen batteries. A swollen battery can overheat and build up pressure inside your device. This pressure may cause the battery to catch fire or even explode. Fires from batteries can destroy your electronics, your home, or even your car. Sometimes, these fires reignite after you think they are out, making them even more dangerous. People have suffered burns, hearing loss, and other serious injuries from battery explosions. You may also lose valuable belongings if a fire spreads.

Alert: If you see smoke or flames, move away and call emergency services right away.

Chemical Hazards

Swollen batteries release toxic gases that can harm your health. When a battery swells or catches fire, it can emit dangerous chemicals like hydrogen fluoride, phosphorus pentafluoride, and phosphoryl fluoride. These gases are both toxic and flammable. Breathing them in can cause throat burns, lung damage, or other health problems. Fires from batteries also produce carbon monoxide and carbon dioxide, which are harmful in closed spaces. You should never try to puncture or open a swollen battery, as this can release even more hazardous chemicals.

Device Damage

The risks of swollen batteries do not stop at fire or health hazards. Swelling puts pressure on the inside of your device. This pressure can crack screens, break the frame, or damage important parts like the motherboard. Your device may stop working or fail completely. Manufacturers use safety features to help prevent this, but no device is immune. If you notice your device acting strangely, check for signs of swelling right away. Early action can save your device and keep you safe.
