Cell Phone Batteries

DID YOU KNOW?

Cell phones are now the leading cause of fires in checked airline baggage, according to the FAA. [2] Battery failures may be rare — but when they happen, the results can be explosive.

KNOW THE RISK

  • Smartphones have become essential in our daily lives — but the lithium-ion batteries that power them carry serious risks when damaged, defective, or misused.
  • Battery fires and explosions are usually the result of overheating, physical damage, or manufacturing flaws. [1]
  • While rare, phone-related fires can cause serious burns, property damage, or even full building evacuations. Fires can start while charging or even while the device is idle in a pocket or bag.

MITIGATE THE RISK

1. Know the Warning Signs

  • Stop using your phone immediately if the battery hisses, pops, swells, becomes unusually hot, or emits a strange odor. These are signs of imminent failure. [1]

2. Protect the Battery

  • Use a sturdy phone case to prevent punctures and drops that could damage the internal battery. [1]

3. Avoid Extreme Temperatures

  • Leaving a phone in a hot car or freezing environment can degrade battery health and increase risk of fire. Keep it between 32°F and 95°F. [1]

4. Charge Safely

  • Never cover a phone while charging, especially with blankets or pillows. Always charge on a hard, nonflammable surface and use the original charger. [1]

BATTERY SAFETY REMINDER

Cell phones go with us everywhere — but they’re not immune to danger. Practice safe charging habits, recognize warning signs, and don’t ignore battery issues. A little prevention goes a long way when it comes to avoiding a fiery mishap.
