Lithium – Ion Batteries : Use and Charging
“Charge into Fire Safety, Safe Charging is a SUPERPOWER” is the 2026 National Fire Protection Association FIRE PREVENTION WEEK (October 4-10) theme. Lithium-ion batteries store a lot of energy in a small space. These batteries can overheat, start a fire, or explode if overcharged or damaged. Safe charging means making smart choices every time you plug in.
Consider the Following:
• Use the cord and charger that came with your device or one approved by the manufacturer. Using the wrong charger can damage the battery and increase the chance of fire. Cheap or off-brand chargers may not meet important safety standards. Buy products listed by a nationally recognized laboratory, such as UL, ETL or CSA.
• Charge on a hard, flat surface like a table, desk, or bare floor. Devices and chargers create heat during normal charging. Soft surfaces like beds, pillows, and couches can trap heat and block airflow, which can cause a battery to overheat.
• Stop using your device if it feels very hot, starts to swell, smells strange, leaks, smokes or makes popping or hissings sounds. A damaged battery can overheat and start a fire.
• Unplug your device when it is fully charged. Leaving a device plugged in can increase heat and stress on the battery.
• Charge large items like e-bikes, scooters, and power tools outside when possible. Do not block exits when charging. These batteries are larger and store more energy. Fires can grow quickly if the battery fails.
• When on a plane, keep devices where you can see them while charging. Do not charge e-cigarettes or vapes on the plane. Tell a flight attendant if you notice a problem with your device, such as if it feels very hot, starts to swell, is smoking, or has a strange smell. If a battery overheats or fails, it is important for the flight crew to be able to respond quickly.
Also Remember:
This month is Halloween. Please consider fire safety when decorating and pedestrian safety while driving.
