There’s a small but real chance that the lithium-ion battery in your device could explode. Between 2012 and 2017, the U.S. Consumer Product Safety Commission estimated at least 25,000 fires involving these batteries, and incidents continue to occur. In 2023 alone, New York City reported 200 fires linked to lithium-ion batteries. While some of these incidents may involve external factors, like a pet chewing on your device, the reality is that these batteries can and do sometimes spontaneously ignite.
The good news is that there are warning signs indicating that your rechargeable battery might be on the verge of an explosive malfunction.
Warning Signs Your Battery May Be About to Explode
Lithium-ion batteries function through chemical reactions that move electrons from one material to another. However, under certain conditions, these reactions can become unstable, often with warning signs:
Heat: It’s normal for rechargeable batteries to generate heat during use—your phone, for instance, might feel warm to the touch and can reach up to 95 degrees under typical conditions. However, if your device becomes too hot to touch, this is a clear indication that something is wrong. If your device feels unusually hot, it could be on the verge of exploding.
Swelling: A swollen lithium-ion battery is usually the result of heat and gas buildup. While swelling alone doesn’t guarantee an imminent explosion, it’s a serious warning sign, especially if accompanied by other symptoms.
Smoke: If you see white or gray smoke emanating from your device, the battery is likely about to explode. Any visible vapor or smoke is a strong indicator that an explosion is imminent.
Sound: Unusual sounds like hissing or bubbling can also indicate that your battery is heading toward a dangerous situation.
If you notice any of these warning signs, it’s best to assume that your battery is about to catch fire and take immediate precautions.
What to Do If Your Battery Is About to Explode
If you suspect that one of your rechargeable batteries is going to explode, follow these steps:
Evacuate the Area: If you see smoke or sparks, evacuate immediately to avoid injury.
Protect Your Hands: Don’t handle the device with bare hands. Use something like tongs, oven mitts, or a thick towel to protect yourself from potential burns.
Turn Off and Unplug the Device: If possible, disconnect the device from its power source and shut it down to prevent further damage.
Move the Device Carefully: Handle the device gently and relocate it to an isolated area where any potential flames can be contained—such as a garage with a concrete floor or an exterior spot on pavement. If you have a fireproof container, place the device inside, but still move it away from living areas.
Suppress the Fire: If the device catches fire, use a fire extinguisher (preferably class D for metal fires) or a hose to extinguish the flames. If the device is large, like an eBike, it’s best to call the fire department for assistance.
By staying alert to these warning signs and knowing how to react, you can mitigate the risks associated with a potential battery explosion.
