Safety Tips for Lithium-Ion Batteries

Lithium-ion Battery Fire Safety

Lithium-ion batteries are used in various devices, commonly powering cell phones, laptops, tablets, power tools, electric cars, and e-micromobility devices such as e-bikes and e-scooters . Lithium-ion batteries store a large amount of energy and can pose a threat if not treated properly.

Given the nascent industry and lack of federal standards for e-micromobility products, a number of the batteries in these devices are or become defective and can overheat, catch fire, or explode. In 2023 alone, there were 268 fires caused by lithium-ion batteries, many of which were used to power e-bikes.

General Safety Tips:

• When purchasing devices, look for the Underwriter Laboratories (UL) Mark. The UL mark shows that the product has been tested to nationally recognized safety standards.
• Follow the device manufacturer’s instructions for charging and storage. Always use the manufacturer’s cord and power adapter made specifically for the device.
• When purchasing a new battery, buy the manufacturer’s battery that is compatible with your device. Do not seek alternative battery options.

FDNY Public Education Campaign:

The FDNY launched a $1 million education campaign to raise public awareness about the historic increase in lithium-ion battery fires in New York City and the dangers that uncertified batteries pose — even when they are not charging.

The ads will appear online, on subways and buses, in digital kiosks, in targeted newspapers, and on the radio. Translated into ten languages, they highlight the destructive potential of battery fires and will be strategically placed in neighborhoods with a high incidence of lithium-ion battery fires.

E-micromobility Battery & Device Dos:

• If possible, charge your device outside.
• Keep your batteries and device at room temperature.
• Plug your device charger directly into a wall outlet.
• Store and charge batteries away from anything flammable.
• Monitor your battery for any odors, changes in shape or color, leaking, or odd noises.
• If you notice any of these conditions, discontinue use immediately. If it is safe to do so, move the device away from anything that can catch fire and call 9-1-1.

E-micromobility Battery & Device Don’ts:

• Do not charge your device near exits and points of egress, including your apartment door, bedrooms door, and windows (particularly near a window with a fire escape).
• Do not charge your device in your bedroom.
• Do not charge your device on any surface other than the floor.
• Do not place your battery or charge in direct sunlight.
• Do not charge using an extension cord.

Battery Disposal:

• Putting lithium-ion batteries in the trash or recycling at home is illegal.
• Recycle batteries by taking them to a Special Waste Drop-Off Site. Visit  nyc.gov/batteries for disposal instructions and more disposal options near you.
• Individually bag batteries or tape ends before disposing of them.
