Lithium-ion batteries are part of everyday life. They power cell phones, laptops, tablets, cordless tools, e-bikes, scooters, cameras, toys, and many other devices used at home and at work. Most people use these batteries every day without thinking much about them.
The convenience is great, but there is a risk that should not be ignored. When a lithium-ion battery is damaged, poorly made, incorrectly charged, exposed to heat, or used with the wrong charger, it can overheat and create a fire hazard. These fires can burn quickly and may be difficult to control.
The good news is that a few simple habits can help reduce the risk.
Use the Right Charger
One of the most important safety steps is using the charger and power adapter designed for the device. A charger that fits does not always mean it is the correct charger. Using an incompatible charger can create too much heat or stress the battery.
Avoid cheap replacement chargers, off-brand batteries, or parts that are not approved by the manufacturer. This is especially important for e-bikes, scooters, power tools, and other larger battery-powered devices.
When buying a new device, battery, or charger, look for products that have been tested by a recognized safety testing organization. A lower purchase price is not worth the risk of a fire.
Charge Batteries in a Safe Location
Do not charge lithium-ion batteries on a bed, couch, under a pillow, or near paper, clothing, curtains, rugs, or other items that can catch fire. A hard, flat, open area is a safer choice.
For larger devices such as e-bikes and scooters, avoid charging near doors, hallways, stairways, or windows that may be needed as an exit during a fire. Never block an escape route with a charging device.
It is also a good idea to unplug devices once they are fully charged. Avoid leaving larger batteries charging overnight or unattended for long periods of time.
Watch for Warning Signs
A lithium-ion battery may show signs of trouble before it fails. Stop using the device if you notice:
- Swelling or a change in shape
- Unusual heat
- A strange odor
- Leaking
- Popping, hissing, or crackling sounds
- Smoke
- A change in color
- A battery that no longer charges properly
If any of these warning signs appear, move the device away from anything that can burn only if it is safe to do so. Do not keep using it, do not try to charge it again, and do not attempt to repair the battery yourself.
Store Batteries Carefully
Store lithium-ion batteries at room temperature when possible. Keep them away from direct sunlight, heaters, hot vehicles, and extreme cold. Heat can increase stress on the battery, and damaged batteries can become more dangerous when stored near flammable materials.
If you store spare batteries, keep them away from metal objects such as coins, keys, tools, or loose hardware. Battery terminals can short if they come into contact with metal.
Businesses that store multiple battery-powered tools, devices, scooters, or equipment should have a clear charging and storage area. Employees should know where devices can be charged, what chargers are approved, and what to do if a battery looks damaged.
Travel Safely With Lithium-Ion Batteries
Lithium-ion battery safety is also important when you travel. Phones, laptops, tablets, cameras, power banks, rechargeable toothbrushes, medical devices, and other electronics may all contain lithium-ion batteries.
Before flying, review the rules for your airline and your destination. Spare lithium-ion batteries, portable chargers, and power banks are generally required to travel in your carry-on bag, not in checked luggage. If your carry-on bag is checked at the gate, remove spare batteries and power banks before the bag is placed under the plane.
Keep batteries protected while traveling. Cover exposed terminals, keep spare batteries in their original packaging when possible, or place them in individual bags or protective cases to help prevent contact with keys, coins, tools, or other metal items.
Battery size can also matter. Some larger lithium-ion batteries may require airline approval before you travel. This can include certain camera batteries, drone batteries, medical equipment batteries, and other high-capacity rechargeable batteries.
If you are unsure whether a device or battery is allowed, contact your airline before traveling. Airline rules can vary, and it is better to ask ahead of time than to find out at the airport that a battery cannot be packed the way you planned.
Be Careful With E-Bikes and Scooters
E-bikes and scooters can carry larger lithium-ion batteries than many household devices. That means safe charging and storage habits are especially important.
Do not charge an e-bike or scooter in a bedroom. Do not charge it near an exit. Do not use extension cords as a permanent charging solution. Follow the manufacturer's instructions, and avoid replacement batteries or chargers that were not made for that specific model.
If the battery has been dropped, crashed, exposed to water, or damaged, have it inspected by a qualified professional before using it again.
Dispose of Batteries the Right Way
Lithium-ion batteries should not be thrown in the regular trash. They should also not be placed in standard household recycling bins. Damaged or improperly discarded batteries can create fire risks during collection, transport, or processing.
Check with your local waste authority, recycling center, hardware store, or battery recycling program for proper disposal options in your area. Before recycling, follow local guidance for taping battery terminals or bagging batteries individually.
Review Fire Safety at Home and Work
Battery safety should be part of a larger fire prevention plan. Make sure smoke alarms are working, exits are clear, and everyone knows what to do if there is a fire.
For businesses, lithium-ion battery use may affect workplace safety procedures, employee training, property risk, and emergency planning. This is especially true for contractors, restaurants, delivery operations, repair shops, offices with many devices, and businesses that use battery-powered tools or equipment.
How Insurance Fits In
Fire damage can be costly, whether it happens at home, in a garage, in a rental property, or at a business location. Insurance policies can vary based on the type of property, how the battery-powered device was used, where it was stored, and the details of the loss.
A homeowners, renters insurance, condo, commercial property, general liability, or business owners policy may respond differently depending on the situation and policy language. Reviewing your current policies can help you better understand your coverage, limits, exclusions, and responsibilities.
