Focusing on keeping you safe while using Lithium-Ion Batteries

About Lithium-ion batteries

Rechargeable lithium-ion batteries, also called li-ion batteries, are common in rechargeable
products and generally safe to use. However, they have the same safety risks as other kinds of
batteries, including overheating, fires & explosions.

They’re more easily damaged than other types of batteries and can become hazardous in certain
conditions since they are more volatile.

Lithium-ion batteries are found in many electronic devices, such as:

• toys
• power tools
• baby monitors
• portable power banks, personal electronics, such as:
  • tablets
  • laptops
  • cell phones
  • smartwatches
• vaping products (e-cigarettes)
• e-mobility products such as e-scooters, e-bikes and mobility aids

Safety tips to help minimize the risks associated with lithium-ion batteries

Use and storage

1. Handle lithium-ion batteries carefully. Do not throw, modify or tamper with them. Check for
   signs of damage, and don’t use batteries that:
   a. Are swollen or dented
   b. Have torn, plastic wrappers
   c. Show other signs of damage or wear
2. Keep your batteries in a safe place, out of sight and reach from children. If you carry
   batteries with you, keep them in a protective, non-metal case.
3. Keep batteries stored in a dry location at room temperature. Do not:
   a. Leave batteries out in the sun or in a hot or cold car
   b. Let moisture form on either end of the battery’s terminals

Charging

• Do not charge your battery for longer than the recommended charging time. Overcharging
• can cause your battery to overheat, which can lead to fires or explosions.
• Charge your device at room temperature where you can see it. Soft surfaces, like a couch
• or bed, can trap heat around the battery and cause the device to overheat.
• Charge your battery before it drops below 30% to help it last longer and work safely. Do
• not keep it plugged in and charged at 100% for long periods.
• Unlike older types of batteries, you do not need to fully discharge lithium-ion batteries. This
• may harm them.
• Charge your product away from exit doors in case of fire.

Original and replacement chargers

• Use the charger that came with your device. 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 product manufacturer if you need a replacement charger for higher
• voltage items like e-bikes, remote control cars and power tools.
• Only use chargers that have one of the recognized Canadian certification marks, such as:
  • o CSA, ULC
