Take lithium-ion battery risks seriously. Follow the guidelines and stay safe.

Lithium-ion batteries are found in many common devices, including e-bikes, mobility scooters, e-cigarettes, vacuums, lawn equipment, smoke alarms and toys. Certified lithium-ion batteries that are properly charged, used and disposed of are generally safe. Overcharged, modified or damaged batteries are not safe and can cause a fire or even explode.  

  • Always follow manufacturers’ instructions. 
  • Use only the battery that is designed for the device and the charger cable/cord that came with it. If you need to replace your charger, buy it from a trusted source and make sure the voltage and current are compatible with your device. 
  • Contact the original manufacturer if you need a replacement charger for items such as e-bikes, remote control cars and power tools. 
  • Make sure chargers have one of the recognized Canadian certification marks, such as: 
    • CSA 
    • cUL 
    • cETL 
  • Never modify or tamper with your battery.  
  • Keep your battery in sight when charging and unplug it when charging is complete.  
  • Do not cover or charge your device on soft surfaces such as under your pillow or on your bed or couch. 
  • Store lithium-ion batteries at room temperature.  
  • Do not place lithium-ion batteries in direct sunlight or keep them in hot vehicles. 
  • Avoid using a device in a highly damp or humid environment. 
  • Store lithium-ion batteries away from anything that can catch fire. 
  • Avoid crushing, bending, or dropping a device and charger. 
  • If you notice the battery or device is sparking or smoking call 911. If it is safe to do so, move the battery or device outside and away from anything that could catch fire. 

Lithium-ion batteries are household hazardous waste and should never be placed in the garbage, Blue Bin (recycling) or Green Bin (organics). Bring lithium-ion batteries to one of the City’s Drop-Off Depots or a Community Environment Day for safe disposal. 

You can also arrange a free Toxic Taxi pickup from the City if you have between 10 to 50 litres/kilograms of household hazardous waste. 

Improper storage and disposal of batteries can cause fires. Place batteries in a clear plastic bag or seal terminals with clear packing tape, duct tape or electrical tape. Store batteries in a cool, dry place and drop them off for safe disposal as soon as possible. Damaged batteries should be dropped off for safe disposal immediately.
