eBike's battery charging

Lithium-ion batteries power much of our modern world – from smartphones and laptops to power tools, electric vehicles and increasingly popular devices like eBikes and eScooters. These batteries are lightweight, efficient and essential for everyday convenience. But with their benefits come important safety considerations.

If damaged or used incorrectly, lithium-ion batteries can overheat, catch fire or even explode. When fires occur, they burn at extremely high temperatures, release flammable and toxic gases and are notoriously difficult for firefighters to extinguish.

Follow these precautions to stay safe

There are several ways to reduce the risk of fires involving lithium-ion batteries and devices. Keep these safety tips in mind when using, charging or storing items that use lithium-ion batteries:

  • Check the device, charger, cords and batteries regularly for any signs of damage such as swelling, leaks or corrosion.
  • Only purchase and use devices, batteries and charging equipment that are listed by a nationally recognized testing lab and labeled accordingly.
  • Always follow the manufacturers instructions.
  • Stop charging a battery once it is full – overcharging can cause the battery to overheat. Only charge the device or device battery for the recommended charging time.
  • Only charge one device or device battery at a time to prevent overloading the circuit. Plug them directly into a wall socket over an extension cord.
  • Charge batteries and devices on a non-combustible surface in a non-combustible area.
  • Avoid extreme temperatures. Keep batteries at room temperature when possible. Do not charge them at temperatures below 0 Celsius or above 40 Celsius.

Stop using the device if you notice:

  • unusual odour
  • change in colour
  • too much heat
  • change in shape
  • smoking
  • not keeping a charge
  • any other damage
