Lithium-Ion Battery Safety

Lithium-ion batteries supply power to many kinds of devices including smart phones, laptops, e-scooters and e-bikes, e-cigarettes, smoke alarms, toys, and even cars. If not used correctly, or if damaged, these batteries can catch on fire or explode.

The Problem

  • These batteries store a large amount of energy in a small amount of space.
  • Sometimes batteries are not used the right way; batteries not designed for a specific use can be dangerous.
  • Like any product, a small number of these batteries are defective. They can overheat, catch fire, or explode.

Safety Tips

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

Signs of a Problem

Stop using the battery if you notice these problems: odor, change in color, too much heat, change in shape, leaking, or odd noises.

  • If it is safe to do so, move the device away from anything that can catch fire.
  • Call 9-1-1.

Battery Disposal

Do not put lithium-ion batteries in the trash.

  • Recycling is always the best option.
  • Take them to a battery recycling location or contact your community for disposal instructions.
  • Do not put discarded batteries in piles.

Charging and E-bike

Charge your 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.
