Lithium-ion batteries in the home:
Lithium-ion batteries power many of the devices we rely on every day. Recent estimates suggest the average household has around 20 to 25 rechargeable devices, including mobile phones, tablets, laptops, smartwatches, power tools, headphones, e-bikes, e-scooters, cordless vacuum cleaners, children’s toys, portable power banks and smart home products.
Are lithium-ion batteries safe?
Lithium-ion batteries are generally safe when used, charged and stored in accordance with the manufacturer's instructions. However, if they are damaged, used incorrectly or charged unsafely, lithium-ion batteries can fail and cause fast-moving fires that release harmful gases. These fires can occur while a battery is charging or even when it is not in use.
Signs a lithium-ion battery may be unsafe:
Check devices regularly for signs of damage. Stop using a lithium-ion battery immediately if it:
· Feels unusually hot
· Looks swollen or out of shape
· Has been cut, crushed, punctured or damaged
· Smells strange
· Is leaking
· Is releasing smoke, fumes, vapour or gas.
If a battery starts to fail
A failing lithium-ion battery can become dangerous very quickly. If your device gets very hot, makes unusual noises or starts releasing smoke, vapour, gas or a strong smell, do not touch it. Evacuate immediately, close doors behind you if safe to do so, get out and stay out and call Triple Zero (000).
Lithium-ion battery fires can develop rapidly and may be intense and unpredictable. They can release toxic and flammable gases and eject burning material or battery components.
Store and recycle lithium-ion batteries safely:
Keep lithium-ion batteries in a cool, dry, well-ventilated place. Keep them away from heat, direct sunlight and things that can catch fire. Good storage helps stop a battery fire spreading to other items in the home.
Store your batteries individually, away from other batteries. Do not store them in a pile.
Do not put old or damaged lithium-ion batteries in your household bin. Batteries in bins can start fires in rubbish trucks and waste facilities. Cover both ends of the battery with tape before taking old batteries to an approved recycling or drop-off point. Damaged batteries should be placed in a non-flammable container. Contact your local council for more information about local collection points or visit Australia’s B cycle battery recycling scheme .
Lithium-ion battery safety at home
To help keep your household safe:
Only buy batteries and devices from trusted sellers.
Always use the charger that came with the device or a genuine replacement recommended by the manufacturer. Do not use cheap, unknown or aftermarket chargers.
Only use replacement batteries made for your device.
· Charge devices on a hard surface that will not catch fire, such as stone, concrete or tiles.
· Avoid charging your devices when you’re asleep or away from home. If something goes wrong, you may need to act quickly to reduce the risk of fire.
· Keep batteries away from heat, direct sunlight and things that can catch fire.
· Regularly check your devices and chargers for signs of damage. Do not use or charge them if they are damaged, overheating, swollen, leaking, making unusual noises or releasing smoke, vapour or gas.
· Do not collect old or damaged batteries inside your home or garage while waiting for disposal.
· Dispose of old or damaged batteries at an approved recycling or collection point.
