Calgary Fire Department warns of the dangers of lithium batteries

Lithium-ion batteries are used in many items, including smart phones, laptops, e-scooters, e-cigarettes, toys, smoke alarms, cars and energy storage systems. While these batteries are extremely safe we know that when these batteries are not used or charged properly, they can start a fire or explode.

In Calgary, fires caused by lithium-ion batteries have increased by 150% from 2021 to 2022. As these batteries store a large amount of energy in a small space, they can overheat and pose a fire hazard if they are not used correctly.

Safety tips

  • When considering purchasing a device, choose those that are listed by a qualified testing laboratory.
  • Only use the battery that is designed for the device and put the batteries in as per the manufacturer’s instructions.
  • Only use the charging cord that came with the device.
  • If the device is damaged, take it to a qualified inspector for service before using or charging.
  • Do not charge a device under your pillow, on your bed or on a couch. Place the device on a hard surface to allow airflow around the device.
  • Keep batteries at room temperature and away from direct sunlight. Do not store batteries in hot vehicles.
  • Store batteries away from heating equipment or anything that can catch fire.
  • Avoid crushing, bending, or dropping a device and charger.
  • Never leave mobility devices unattended and charging in narrow exits such as doorways and hallways. In the event of a fire, this will block your escape. 

“CFD is reminding all Calgarians to buy, store and charge items with lithium-ion batteries safely” says Chief Steve Dongworth. “Please ensure that you are aware of the safety tips and that you know how to charge and dispose of these batteries properly.”
