The rechargeable batteries are found in e-scooters, e-cigarettes, e-bikes, electric vehicles, golf buggies, power banks, vacuum cleaners, power tools and gardening appliances.
CFA Deputy Chief Officer Garry Cook said lithium-ion battery fires were avoidable if appropriate steps were taken.
"When lithium-ion batteries are damaged, misused or fail to meet compliance standards, they pose a serious fire risk, particularly while they are connected to chargers," he said.
“These devices make our lives easier. However, people should know the risks and make sure they use e-products correctly."
Mr Cook said the best way to ensure safety was to buy from reputable suppliers, follow manufacturers' instructions and use only compatible chargers.
Fire Rescue Commissioner Gavin Freeman AFSM said fire crews were responding to an increasing number of fires caused by lithium-ion batteries, which had led to severe damage.
“It’s important that people never store e-products in places that would block exits in the event of a fire,” Mr Freeman said.
“Stop using or charging the product if you notice strong odours, extreme heat, change in shape, leaking or hissing and popping sounds, as these are indicators the product may catch alight.”
Victorians who own or are considering purchasing a lithium-ion battery-powered product can take the following actions to keep themselves and their families safe:
- Purchase products from reputable suppliers.
- Only use chargers and cords that are supplied with the device.
- Don’t modify or tamper with the batteries and the appliances they power.
- Don’t leave batteries charging in direct sunlight or for longer than they need to.
- Only charge batteries on non-combustible surfaces in a room where a smoke alarm is present.
- Don’t use batteries or devices that show signs of swelling, bulging, leaking or overheating.
- Don’t charge items close to a door, which would block your exit if the item did catch fire.
If your e-product does catch fire Victorians are advised to do the following:·
- Call Triple Zero (000) immediately
- Stop using the product if you notice overheating, bulging, leaking or unusual sounds.
- Leave the area, even if you no longer see flames or smoke.
- It’s not safe to attempt to put the fire out yourself, as batteries involved in fire can release toxic gases and generate multiple explosions.
- Ensure firefighters attend to make the area safe.
- Never throw lithium-ion batteries in your regular waste or recycling collection bins. Many battery-related fires start in household bins, garbage trucks and waste facilities.
