Swollen batteries are dangerous and should be handled with care. If your phone, laptop, or other electronic device has a battery that is expanding or bulging, it’s important to take action immediately. Improper disposal can harm the environment and pose fire hazards. This guide will help you safely manage and dispose of a swollen battery.
What to do with a swollen battery
If you notice a battery swelling, follow these steps to reduce the risk of explosion or fire:
✔ Stop using or charging it immediately. Continued use can make the swelling worse and increase the danger.
✔ Do NOT puncture or try to flatten it. Damaging the battery can cause leaks or combustion.
✔ Store it in a fireproof container. Use a metal can filled with sand or another non-flammable material.
✔ Dispose of it properly. Take the battery to a hazardous waste facility or a recycling center specializing in battery disposal, such as Call2Recycle, Batteries Plus Bulbs, or a local household hazardous waste (HHW) collection site.
Even if a swollen battery has exploded, punctured, or is no longer functioning, it can still be recycled safely. (Check out our Recycle cell phone batteries blog)
Where to dispose of a swollen battery
Due to their hazardous nature, swollen batteries require careful handling when being transported for disposal. Not all battery recycling locations accept damaged batteries, so always confirm before dropping them off.
Accepted disposal locations:
✔ Local Hazardous Waste (HHW) Programs – Many cities and counties have drop-off sites for hazardous materials.
✔ Call2Recycle – Offers a locator tool, but call ahead to ensure they accept swollen batteries.
✔ Battery Retailers – Some locations of Batteries Plus Bulbs or Interstate All Battery Center may accept damaged batteries.
✔ Mail-in Recycling (with Safety Precautions)
While most junk removal services do not accept hazardous waste, 1-800-GOT-JUNK? can help remove electronic waste, including batteries, for safe disposal.

Why do lithium batteries swell and will a swollen battery explode?
Lithium-ion batteries swell due to excessive heat, overcharging, manufacturing defects, or age-related chemical breakdown. Gas buildup inside the battery causes expansion, and while not all swollen batteries explode, they can catch fire or burst if punctured or mishandled. Proper disposal is crucial to prevent potential hazards
