Take Care with Lithium-Ion Batteries: Safety Tips for Everyday Devices

Lithium-ion batteries are everywhere in our daily lives. They power our cell phones, tablets, laptops, E-bikes, power tools, vapes—you name it. These batteries are popular because they are lightweight and can store a lot of energy relative to their size, making them the perfect match for many modern gadgets. But while they are generally safe, they’re not without risks, especially if used improperly.

This became all too clear in May when a dog in Tulsa, Oklahoma, decided to chew up a charger. Captured on home video, the dog grabbed the charger, dragged it back to his bed, and began gnawing away. The battery caught fire within moments, quickly igniting the dog’s bed. Thankfully, both dogs and the family cat escaped safely through a dog door, but firefighters reported significant damage to the home. It was a close call that highlighted just how dangerous lithium-ion batteries can be if mishandled.

Lithium-ion batteries can spark, catch fire, and even explode when damaged or misused. To keep your devices safe and avoid accidents, follow these important safety tips:

1. Avoid Removing Non-Replaceable Batteries
Many devices are not designed for you to remove the battery—often, these batteries are glued into place. Trying to force them out can lead to a dangerous situation where the battery could catch fire or even explode immediately. Only remove a battery if the device is specifically designed for battery replacement.

2. Handle Spent Batteries Properly
If you need to remove a spent battery, take extra precautions. Place the battery in a clear, sealable bag or tape the terminals with clear packing tape. This reduces the risk of fires if the battery comes into contact with other metals or batteries.

3. Mind the Temperature
Lithium-ion batteries are sensitive to temperature extremes. Devices with these batteries should not be exposed to extreme heat or cold—room temperature is ideal. And never charge your devices in direct sunlight, as overheating can lead to fire risks.

4. Be Careful About Where You Charge
Charging devices outside is best if possible. When charging inside, place your device on a hard, non-flammable surface, like a countertop, and avoid charging in bedrooms. It’s particularly important not to charge in any area where the device could block your exit in case of a fire. Safety first!

5. Plug In Safely
Always plug chargers directly into a wall socket. Avoid using extension cords, which can be a fire hazard if overloaded. Also, stick with the manufacturer-recommended cords and chargers. Using cheap, off-brand chargers might save a few dollars, but they can be dangerous because they may not meet safety standards.

6. Don’t Overcharge
Avoid overcharging devices. Leaving a device plugged in after it’s fully charged can stress the battery, increase the risk of overheating, and reduce the battery’s overall lifespan. Once your device is fully charged, unplug it.

Lithium-ion batteries are powerful tools that make our favorite gadgets work, but they require some care and caution. By following these simple safety tips, you can help ensure that your devices work safely and effectively—and avoid fiery mishaps like the one in Tulsa. Remember, some prevention can go a long way in keeping you and your home safe.
