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.

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.
