Lithium-Ion Battery Safety

Lithium-ion batteries are increasingly found in devices and systems that the public and first responders use or interact with daily. While these batteries provide an effective and efficient source of power, the likelihood of them overheating, catching on fire, and even leading to explosions increases when they are damaged or improperly used, charged, or stored. 

Quick Background

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

  • Lithium-ion 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 nationally-recognized testing laboratory.
  • Always follow the manufacturer’s instructions.
  • Only use the battery that is designed for the device.
  • 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. 

Recycle Batteries Responsibly 

Do not throw lithium-ion batteries in the trash or regular recycling bins because they could start a fire. Recycle your device or battery at a safe battery recycling location. Visit call2recycle.org to find a recycling spot near you.
