Lithium-Ion Battery Safety

Posted on May 14, 2024 By

Lithium-ion batteries supply power to various devices, including smart phones, laptops, e-scooters and e-bikes, e-cigarettes, smoke alarms, toys, and even cars. If not used correctly or if they are damaged, these batteries can catch on fire or explode. Because of all the recent fires, the Lakewood Board of Fire Commissioners and Fire Chief Jonathan Yahr present the following Lithium-ion battery safety tips.

Purchase and use devices that are listed by a qualified testing laboratory (UL). Always follow the manufacturer’s instructions. Only use the battery that is designed for the device and put the batteries in the device the right way. Only use the charging cord that came with the device. Do not keep charging the device or the device battery after it is fully charged. Do not charge a device under your pillow, on your bed, or on a couch. Keep batteries at room temperature when possible. Do NOT charge them at temperatures below 32 degrees Fahrenheit (0 C) or above 105F (40 C). Be sure to store batteries away from anything that can catch fire.

Signs of a problem include odor, change in color, too much heat, change in shape, leaking, or odd noises. If safe to do so, move the device away from anything that can catch fire and call 9-1-1.

If you need to dispose of lithium-ion batteries, recycling is always best. Take batteries to a recycling location or contact your community for disposal instruction. NEVER put lithium-ion batteries in the trash.

Special instructions for charging an e-bike: Charge the battery in a flat, dry area away from children, direct sunlight, liquids, tripping hazards, and in a location where the e-bike is not at risk of falling.
