How to Safely Use Lithium-Ion Batteries in Everyday Devices
Lithium-ion batteries are powering more of our everyday devices—from e-bikes and power tools to smartphones and children's toys. Their compact size and high energy capacity make them incredibly useful, but they also carry a risk of fire if misused or damaged.
A recent house fire in Vilas County was linked to a lithium-ion battery in an e-bike, highlighting the importance of safe usage. According to Nicole Sanders of the UL Fire Safety Research Institute, most certified lithium-ion batteries are safe when used and stored as intended. Problems often arise from misuse, uncertified products, or improper charging practices.
To help prevent battery-related fires, the Fire Safety Research Institute’s Take CHARGE of Battery Safety campaign recommends:
- Always follow the manufacturer’s instructions.
- Use only the charger provided or one made for the device.
- Avoid charging near exits or flammable materials.
- Charge large devices like e-bikes outdoors and never overnight.
- Watch for warning signs like heat, smoke, bulging, or strange noises.
If a battery shows signs of failure, unplug it immediately. And if a fire starts, evacuate and call 911—don’t try to handle it yourself.
Fire safety starts with awareness and certified products. Taking simple precautions can make a big difference in keeping your home and family safe.
