Lithium-ion batteries power countless modern electronic devices throughout our homes and workplaces. With proper use and care, these batteries are safe, but if they overheat or incur damage, they can cause a fire. Lithium-ion battery fires continue to arise and have become a pervasive problem across the country, especially in New York City. According to the FDNY, in 2023 alone, 243 fires have been caused by lithium-ion batteries, leading to 124 injuries and 17 deaths. These batteries are everywhere- from cellphones to laptops, e-bikes, electric scooters, and electric vehicles, so it is imperative for the public to learn how to handle these batteries properly during their entire lifecycle.
Some major cities throughout the globe, including London and Madrid, have banned electric scooters on public transportation because of the fire risk they pose. A lithium-ion battery fire ignited by a portable charger occurred on a recent flight originating at New York’s John F. Kennedy International Airport (JFK) in November 2023, prior to takeoff. Regulation of the batteries, support for first responders, and public education will be imperative to keep the incidence of fires low. Thermal runaway from these fires can be a catastrophic issue for all audiences, so widespread education is imperative. When a lithium-ion battery goes into thermal runaway, the fire can become uncontrollable and self-heating, making it difficult to extinguish.
The Electrical Safety Foundation (ESFI) is launching its 2023 holiday safety campaign in conjunction with the Fire Safety Research Institute (FSRI) to educate consumers on how they can take charge of battery safety by making safe choices when purchasing or receiving lithium-ion battery-powered devices. ESFI’s campaign will provide information on how to avoid injuries and fires caused by lithium-ion batteries.
With the endless number of retailers in the market, selecting what lithium-ion battery-powered devices to purchase can be difficult. When researching what to buy, choose a trusted retailer who stands behind their products. Select a product with a warranty that was certified by a Nationally Recognized Testing Laboratory- they protect consumers against unsafe products. If you require a replacement battery, purchase one from a reputable retailer. Dispose of old batteries responsibly at recycling centers.
Before using or charging the device, thoroughly read the owner’s manual for the manufacturer’s guidance and information. When charging the device, choose a flat, dry area away from children, sunlight, and entrances where a fire could block an escape route. Always use a manufacturer-approved charger and avoid adapters when charging. Charge the device by plugging it directly into a wall outlet, and never leave it charging unattended, especially overnight.
Be sure to remove the battery or charger once charging is complete to avoid overheating. Batteries should be stored and charged at room temperature as issues can occur below 32°F or above 105°F. Keep batteries and devices from heat sources or anything that can catch fire. Do not store batteries in vehicles. All maintenance on batteries or devices should be completed by a qualified professional.
If you notice an odd odor, discoloration, the device produces too much heat, there is a change in shape, the battery is leaking, smoking, or not keeping a charge, or you hear something abnormal coming from your device, it could be a sign of danger. If you see something unusual, move the device away from flammable objects and call 911.
Statistics show that the number of home fires and electrical accidents typically increase during the winter holiday season.
