Lithium-ion batteries

Lithium-ion batteries power phones, laptops, power tools, e-bikes and scooters. Most of the time they are safe, but a damaged, overheated or poorly made battery can catch fire.

Charging and storing

• Choose certified products.
• Don't charge batteries below 32°F or above 105°F.
• Store batteries at room temperature when you can, and spare batteries away from anything that can burn.
• Don't leave batteries in direct sunlight or in a hot car.

Warning signs: stop using it

Stop using a battery right away if you notice a smell, a change in color or shape, too much heat, leaking or odd noises.

Getting rid of old batteries

• Don't put lithium-ion batteries in the trash.
• Recycle them at a battery recycling location near you.

If a battery catches fire

Get out quickly and call 911 from outside. These fires spread fast, give off toxic smoke and can explode.
