Lithium Ion Batteries
Lithium-ion batteries supply power to many kinds of devices, including smart phones, laptops, scooters, e-cigarettes, smoke alarms, and toys. Handle these batteries carefully. In rare instances, they can cause a fire or explosion.
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:
- are swollen or dented
- have torn, plastic wrappers
- 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:
- leave batteries out in the sun or in a hot or cold car
- 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 actually 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:
- CSA
- cUL
- cETL
Disposal
After safely collecting and protecting your used household batteries, drop them off at a local battery recycling location.
