Lithium Ion Battery Safety
Charge Into Fire Safety: Safe Charging is a Superpower
Lithium ion batteries are increasingly found in the devices and systems we use every day; from mobile phones and computers, to E-Bikes and even our electric vehicles. With this increased prevalence and use of lithium ion batteries, firefighters are seeing an increase in fires and other emergencies related to their use.
Safe charging means making smart choices every time you plug in. Here are 6 simple steps you can take to charge safely and help prevent fires:Â
Cheap charger? Don’t chance it.
Use the cord and charger that came with your device or one approved by the manufacturer.
Soft surface? Hard pass.
Charge on a hard, flat surface like a table, desk, or bare floor.
Fully charged? Time to unplug.
Unplug your device when it is fully charged.
For tools and rides, charge outside.
Charge large items like e-bikes, scooters, and power tools outside when possible. Do not block exits when charging.
Feels hot? Stop using it.
Stop using your device if it feels very hot, starts to swell, smells strange, leaks, smokes, or makes popping or hissing sounds.
On a flight? Keep it in sight.
When on a plane, keep devices where you can see them while charging. Do not charge e-cigarettes or vapes on the plane. Tell a flight attendant if you notice a problem with your device.
