Stop charging or using a power bank or device if its battery swells, leaks, cracks, overheats, or smells unusual.
Last reviewed: 2026-09-12
Why it matters
A damaged lithium battery can short-circuit, release hot material, or ignite without further warning.
Wrong action
Pressing a swollen casing flat, puncturing it, or continuing to charge the device.
Correct action
Disconnect power if safe, keep people away, and arrange safe inspection or disposal without crushing the battery.
What to do
- Stop use and charging immediately.
- Do not press, puncture, bend, or open the battery.
- Keep it away from heat and ask the employer to arrange safe handling.
If something happens
If it smokes, hisses, becomes dangerously hot, or burns, move away, avoid the fumes, and call 999.
