Lithium-Ion Batteries and Fire Safety: What Guilford Residents Need to Know

As the colder months approach, it's crucial for residents of Guilford, and across the nation to stay informed about the safe use and charging of lithium-ion batteries. These batteries power numerous everyday devices, such as smartphones, laptops, e-bikes, and power tools, but they also present a fire risk if not handled properly. Understanding the broader national context of these risks can help residents take appropriate precautions.

National Fire Statistics and Lithium-Ion Battery Risks:

Lithium-ion battery-related fires are on the rise nationwide. According to recent reports, there were over 25,000 incidents of fire or overheating associated with these batteries in the U.S. between 2017 and 2022. In 2024 alone, the U.S. has seen over 120 incidents involving lithium-ion batteries, many of which involved micro-mobility devices like e-bikes, scooters, and portable power stations. These fires often occur in residential settings, with a significant number starting indoors when batteries are either charging or simply stored.

The growing popularity of electric vehicles (EVs) has also contributed to an increase in lithium-ion battery fires. EV battery fires are less frequent than those in gas-powered vehicles, but when they occur, they can be more severe, sometimes requiring extensive resources and time to extinguish. These fires can reach temperatures up to 4,900°F (2,700°C) and may reignite even after appearing to be extinguished.

Safety Tips for Residents:

1. Use the Correct Chargers: Always use the manufacturer-recommended charger for your device. Using off-brand or incompatible chargers can lead to overheating and potential fire hazards.

2. Avoid Overcharging: Unplug devices when fully charged, and avoid charging them overnight. Overcharging can lead to overheating and increase the risk of a thermal runaway—a situation where internal battery temperatures rise uncontrollably.

3. Supervise Charging Devices: Charge devices on hard, non-flammable surfaces, and avoid placing them on beds, sofas, or carpets where heat can accumulate.

4. Store Batteries Properly: Keep batteries in a cool, dry environment. Exposure to extreme temperatures—either heat or cold—can increase the likelihood of battery malfunction.

5. Check for Damage: If a battery is swollen, leaking, or physically damaged, replace it immediately. Damaged batteries pose a higher fire risk and should be disposed of according to local regulations.

Responding to a Battery Fire:

In case a lithium-ion battery catches fire, remember that traditional methods like using water may not be effective due

to the chemical nature of these batteries. It is best to use a fire extinguisher rated for electrical fires (Class C) and evacuate the area. Always call emergency services for assistance if a fire occurs.

Importance of Awareness:

With the increased use of lithium-ion-powered devices, the potential risks grow as well. By following these safety practices, residents of Guilford and across the U.S. can minimize the risk of lithium-ion battery fires, ensuring a safer transition into the winter months. For further information or assistance with battery safety, reach out to the Guilford Fire Department. Stay safe and stay informed.
