Most of the electronics in our homes — smartphones, tablets, power and lawn tools, laptops, e-cigarettes, headphones, and toys — are powered by lithium-ion batteries.
If not used correctly or damaged, they can overheat and start a fire or explode.
“Charge into Fire Safety™: Lithium-Ion Batteries in Your Home” is the theme of 2025 Fire Prevention Week, which runs from October 5–11. This year’s focus on lithium-ion batteries works to better educate the public about how to buy, charge, and dispose of them safely.
Lithium-ion batteries are powerful, convenient, and they’re just about everywhere, so it’s important to handle them safely to minimize risk, explained Roseville Fire Chief David Brosnahan.
Fire Departments across the Twin Cities have responded to house fires caused by lithium-ion batteries. Roseville firefighters recently assisted a neighboring fire department, which responded to a fire started by a lithium-ion battery powering a child’s scooter.
“Let's work together to prevent battery-related fires. If you ever smell smoke or suspect a battery is overheating, call 911 immediately,” Chief Brosnahan said. “Never try to put out a lithium-ion battery fire yourself unless you are trained to do so and can do it safely. It is important to remember important safety tips as it pertains to these batteries.”
Here are three things you can do to avoid danger when using devices with lithium batteries.
BUY only listed products
- When buying a product that uses a lithium-ion battery, take time to research it. Look for a stamp from a nationally recognized testing lab on the packaging and product such as UL, ETL, or CSA, which means that it meets established safety standards.
- Many products sold online and in stores may not meet safety standards and could increase the risk of fire.
CHARGE devices safely
- Always use the cables that come with the product to charge it. Also, charge the device in accordance with the manufacturer’s instructions.
- If you need a new charger, buy one from the manufacturer or one that the manufacturer has approved.
- Charge your device on a hard surface. Don’t charge it under a pillow, on a bed, or on a couch. This could cause a fire.
- Don’t overcharge your device. Unplug it or remove the battery when it’s fully charged.
DISPOSE OF/RECYCLE batteries responsibly
- Don’t throw lithium-ion batteries in the trash or regular recycling bins because they could catch fire.
- Recycling your device or battery at a safe battery recycling location is the best way to dispose of them. Visit www.call2recycle.org to find a recycling spot near you.
