Many everyday items use lithium or lithium-ion batteries, including phones, tablets, e-bikes, scooters, power tools, toys, and backup chargers. Most are safe when used correctly, but damaged, overheated, poorly charged, or improperly stored batteries can create a serious fire risk. Parents often want straightforward answers about prevention, child safety around lithium batteries, and what to do in an emergency. This page is designed to help you take practical steps without panic.
Use the charger made for the device or one approved by the manufacturer. Charge on a hard, nonflammable surface, keep the area ventilated, and avoid charging on beds, couches, or under pillows.
Stop using a battery if it gets unusually hot, swells, leaks, smells strange, or shows damage after a drop or impact. These can be signs that the battery is no longer safe.
Do not overload outlets, avoid exposing batteries to heat or direct sun, and unplug devices once charging is complete if the manufacturer recommends it. Follow product instructions closely.
Charge where an adult can notice problems early. Keep charging devices away from exits, so a fire would not block escape. If possible, avoid overnight charging for higher-risk items such as e-bikes or scooters.
Store batteries in a cool, dry place away from heat, moisture, and metal objects that could cause short circuits. Keep loose batteries in their original packaging or a protective case and out of reach of children.
Do not throw damaged lithium batteries in household trash. Follow local hazardous waste or battery recycling guidance. If a battery is swollen, hot, or leaking, handle it carefully and contact your local disposal program for instructions.
Store spare batteries, chargers, and high-powered devices where children cannot access them. This is especially important for removable batteries and devices that may be tempting to play with.
Teach children not to touch hot, damaged, or plugged-in charging equipment without an adult. Explain that batteries are not toys and should never be opened, punctured, or put in pockets with coins or keys.
Choose charging spots away from play areas and sleeping areas when possible. Keep cords tidy, reduce clutter around chargers, and make sure adults know where higher-risk devices are charging.
If a lithium battery becomes very hot, starts swelling, smoking, or making popping sounds, move people away from the area right away. If it is safe to do so, unplug the device or charger without touching damaged parts. Call emergency services if there is fire, heavy smoke, or immediate danger. Follow local fire department guidance for lithium battery fire emergency steps, and do not handle a damaged battery more than necessary.
Common warning signs include unusual heat, swelling, leaking, a strong chemical smell, discoloration, smoke, sparking, or crackling sounds. If you notice any of these, stop using the device and move people away from it.
It is safer to charge when someone is awake and able to notice problems early, especially for larger devices like e-bikes, scooters, or power tools. Always use the correct charger and charge on a hard, nonflammable surface.
Store batteries and charging devices out of reach, keep charging areas away from play spaces, and teach children not to touch damaged, hot, or plugged-in battery equipment. Adult supervision and secure storage are key.
Keep them in a cool, dry place away from heat, moisture, and metal objects. Use a battery case or original packaging when possible, and do not leave loose batteries where children can access them.
Do not keep using or charging it. Place it in a safer area away from flammable materials if you can do so without risk, limit handling, and contact your local battery recycling or hazardous waste program for disposal instructions.
