Lithium-ion batteries power many everyday items like phones, laptops, e-bikes, and household appliances/tools. These batteries pack a lot of power into a small space. Caution is necessary as a damaged or improperly used battery can overheat, catch fire or explode.

Four safety elements to check

  • Safety certification marks: only use batteries with a recognized Canadian certification mark from a qualified safety testing laboratory, including ETL, ULC, or CSA and continuously monitor the battery health.
  • CSA logo
    Canadian Standards Association (CSA)
  • Logo for Underwriters Laboratories of Canada
    Underwriters Laboratories of Canada (ULC)
  • ETL Intertek
    Electrical Testing Laboratories (ETL)
  • Improper charging: lithium-ion batteries can be a fire hazard when improperly charged. Avoid overcharging and keep your battery in sight when charging and unplug it when charging is complete.
  • Tampering: never attempt to modify, tamper with, or build your own lithium-ion batteries.
  • Proper disposal: when disposing of lithium-ion batteries treat them as household hazardous waste. They should never be placed in the garbage. Contact your municipality for disposal instructions.

Know the warning signs

Stop using a battery immediately and call 9-1-1 if it shows any of these signs:

  • an odd smell or change in colour
  • the battery feels too hot
  • a change in shape, such as swelling or leaking
  • odd noises coming from the battery

Charging and storage

How a battery is charged and stored can prevent it from overheating.

  • Use the right charger and battery: only use the charger and battery that the manufacturer recommends for the device.
  • Charge on a hard surface: charge devices on a flat, hard surface. Never charge them on beds, couches, or under pillows.
  • Avoid heat and cold: store batteries in a cool, dry place away from sunlight. Do not store or charge in temperatures below 0°C.
  • Keep exits clear: charge battery-powered devices away from doors or hallways so they do not block an escape route if a fire starts.

Buying and recycling

  • Shop at trusted stores: buy from reputable Canadian retailers and avoid fake or unsafe batteries. Many products sold online do not meet the appropriate safety standards.
  • Recycle properly: take old or damaged batteries to an approved drop-off location. Follow local rules for hazardous waste disposal and never place batteries in the garbage.
