Lithium-ion batteries power many of the devices that Ohioans use daily including phones, e-bikes, laptops, power tools, scooters, headphones, toys, and more. When charged or stored improperly, these batteries can fail and sometimes lead to thermal runaway, which causes intense fires that can spread rapidly.
Charging Safety Tips Remember
To help reduce the risk of a fire or dangerous incident, Ohioans are urged to do the following:
* Use the correct charger: Stick with the charger and power adapter that came with your device or one that is certified by the manufacturer. Using an off-brand charger may be convenient, but it can overload the battery and potentially cause overheating.
* Keep batteries cool: Charging on soft surfaces like beds or couches can trap heat. Instead, only place charging devices on a hard, nonflammable surface and keep them out of direct sunlight.
* Give devices space: Avoid charging devices in areas that are cluttered or near anything that can burn. Remember, batteries need airflow to stay cool.
* Charge where you can see them: Don’t leave devices charging overnight or unattended for long periods of time. If you see an item is fully charged, remove it from the charger. Recognizing and acting upon early signs of battery trouble, such as unusual heat, odor, or swelling, can prevent a dangerous situation.
* Protect batteries from damage: Immediately stop using batteries that are crushed, punctured, or swollen. Even small drops can damage internal components and increase fire risk.
* Know the warning signs: If a battery starts smoking, making popping sounds, or feels extremely hot, immediately move it away from anything that can burn – if you can do so safely – and call 911.
* Ensure products have been approved: Look for a stamp from a nationally recognized testing laboratory such as UL, ETL, or CSA on the packaging and product. That stamp means it has met important safety standards. Many products sold online and in stores may not meet these safety standards, which could increase the risk of fire. If you have purchased a product that doesn’t contain one of those approved stamps, you should attempt to return it and discontinue using it.
