In April and June, the Seattle Fire Department responded to two apartment fires that involved lithium-ion batteries. In one fire, the e-bike was being charged on a bed and in the second fire an extension cord was used with the charging cord.

Lithium-ion batteries are small and powerful but when used incorrectly, they can overheat, catch fire, or explode.

How to be safe:

• Only use chargers and cables that are compatible and came with the device – an incompatible charger can cause the device to overheat
• Do not charge a device while sleeping
• Do not charge a device under pillows, on a bed or on a sofa
• Do not continue to charge the battery once it is fully charged 
• Do not charge e-bikes or e-scooters near your primary exit 
• Do not place lithium-ion batteries in direct sunlight or keep them in hot vehicles
• Purchase and use devices that are listed by a qualified testing laboratory

 How to respond:

• Stop using the device if you notice an odor, change in color, too much heat, change in shape, leaking or odd noises.  If it is safe to do so, move the device outside and away from anything that can catch fire.
• If a fire starts, immediately leave the area, close the door as you exit and call 911.
