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
- 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 - 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. - 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
