Lithium-Ion Battery Safety: Phones, E-Bikes, and Chargers

Almost everything you recharge runs on a lithium-ion battery. Phones, laptops, e-bikes, scooters, tools. They pack a lot of energy, and if they're damaged or misused, they can start a fire. Here's how to stay safe.

1. Step 1: Buy Certified

When you buy anything with a lithium-ion battery, look for a safety mark, like UL, ETL, or CSA. That means it was tested to safety standards.

2. Step 2: The Right Charger

Use the cord and charger that came with it. If you need a new one, get it from the maker, or one the maker approves.

3. Step 3: Charge On A Hard Surface

Charge on a hard, flat surface, like a table or the floor. Not on your bed, under a pillow, or on the couch. Soft things trap heat. And unplug it once it's full.

4. E-Bikes And Scooters

Charge big batteries like e-bikes and scooters outside, if you can. And never park them where they'd block a doorway, a hallway, or the stairs.

5. Warning Signs

Stop using it right away if the battery smells strange, gets very hot, makes popping sounds, swells, changes color, or smokes. If it's safe, move it away from anything that can burn.
