Five loss prevention tips for lithium-ion batteries in the home

Lithium-ion batteries power everything from smartphones and laptops to e-bikes and vehicles. While they offer convenience and efficiency, they also pose potential fire risk if mishandled. Here are five essential tips to help homeowners reduce fire risk and stay safe.

1. Charge safely

Overcharging or using incompatible chargers can damage a battery and result in thermal runaway, a chain reaction that can result in fire or battery failure.

Best practices:

  • Always use manufacturer-approved chargers.
  • Batteries should not be left unattended during the charging process.
  • Charge on hard, flat surfaces—never on beds, couches, or near flammable materials.

2. Prevent battery damage

Damaged batteries can result in thermal runaway. A battery may be damaged from physical impact, electrical abuse, or heat.

  • Do not drop, crush, puncture, or strike batteries or equipment that contain batteries.
  • Charging practices and battery use should be done in accordance with the manufacturer instructions.
  • Avoid extreme temperatures by keeping batteries at room temperature and away from heat sources.

3. Store batteries properly

Improper storage can increase the risk of fire. When lithium-ion batteries are in long-term storage, the temperature and level of charge can impact the stress on the battery.

Storage tips:

  • Long-term battery storage should be at charge levels identified by the manufacturer (i.e. 30-50% charge).
  • Keep batteries in a cool, dry place (ideally 59–77°F).
  • Avoid direct sunlight, heat sources, or freezing temperatures.

4. Inspect devices regularly

Regularly inspect batteries, chargers, cords and equipment using lithium-ion batteries for signs of damage.

What to watch for:

  • Swelling, cracks, or unusual heat
  • Strange noises or smoke during charging
  • Devices that feel unusually hot or emit odors

If signs of damage are noticed, unplug the device immediately and contact hazardous waste disposal facility for proper disposal.

5. Dispose responsibly

Disposing of lithium-ion batteries in household waste or standard recycling bins can pose fire risk in homes, collection vehicles, and landfills.

Safe disposal options:

  • Do not throw away these batteries in household trash or recycling.
  • Utilize a hazardous waste disposal facility or retail drop-off locations.
  • Check with manufacturers or local municipalities for recycling programs.

When used in accordance with manufacturer guidance, lithium-ion batteries present fewer risks, but improper handling can lead to serious issues. It is important to adhere to the manufacturers’ guidelines for each device. By observing these five recommendations, homeowners can help minimize fire hazards, safeguard their belongings, and maintain the safety of devices they use daily.
