Battery Fire Safety

Overview

Many everyday items use lithium-ion batteries, including cell phones, laptops, power tools, e-bikes, and scooters. These batteries are generally safe, but they can cause fast-moving fires if they are damaged, charged incorrectly, stored improperly, or thrown away in the trash.

Because lithium-ion batteries store a large amount of energy in a small space, it is important to follow simple safety steps to help protect your home and family.

5 Simple Ways to Prevent Battery Fires

Charge Smart

• Use only the charger that came with your device whenever possible.

• Avoid cheap or unbranded replacement chargers.

• Follow the manufacturer's instructions for charging.

Watch the Heat

• Store batteries in a cool, dry place.

• Keep batteries out of direct sunlight.

• Never leave batteries inside a hot vehicle.

Don't Overcharge

• Unplug devices once they are fully charged.

• Avoid charging batteries overnight.

• Do not leave batteries charging while you are away from home.

Inspect Batteries Often

Stop using a battery immediately if you notice any of the following warning signs:

• Swelling or a change in shape

• Leaking fluid

• Excessive heat

• A strange odor

• A change in color

• Unusual sounds

If a battery shows any of these signs, move away from the device if it is safe to do so. Call 911 if a fire starts.

Clear the Area

• Charge batteries on a hard, flat surface.

• Keep charging areas away from beds, couches, curtains, paper, clothing, and other items that can burn.

• Stay nearby when charging a battery if possible.

Store Batteries Properly

• Store batteries at room temperature whenever possible.

• Keep spare batteries away from metal objects.

• Do not store batteries near flammable materials.

• Never leave batteries in hot cars or direct sunlight.

Recycle Batteries Correctly

• Never throw lithium-ion batteries in the trash.

• Take used batteries to an approved battery recycling or collection site.

• Visit the Battery Network website and use the Call2Recycle Battery Recycling Locator to find a nearby recycling location.

If a Battery Catches Fire

Lithium-ion battery fires can spread quickly and are very difficult to put out.

If you see smoke, sparks, or flames coming from a battery:

1. Get out immediately

2. Stay out

3. Call 911

Do not try to handle a burning battery yourself.
