Fire and Rescue NSW said on Monday its crews responded to 13 lithium-ion battery fires in NSW since February 2, including four fires across 12 hours last week.
So far this year, there were 25 lithium-ion related fires statewide, the agency said.
More lithium-ion batteries in e- bikes, scooters, drones and other rechargeable devices, along with poor quality units, have fuelled a rise in fires, including in NSW where new mandatory safety standards took effect this month.
"We know they are on the rise, but people are still taking dangerous risks in their homes," FRNSW Commissioner Jeremy Fewtrell said in a statement, referring to recent fires.
"Please, heed our advice. Lithium-ion fires are happening to households almost every day."
Fair Trading Minister Anoulack Chanthivong said dodgy lithium-ion batteries presented "a real and potentially life-threatening risk to consumers".
"In response to these risks the NSW government is progressing the introduction of Australia's most comprehensive regulatory regime for e-micromobility devices," Mr Chanthivong said in the statement.
In NSW, mandatory testing and certification will take effect by August, while mandatory labelling is slated to start by February 2026, according to Mr Chanthivong's office.
But Mr Chanthivong said the state could not rely on legislation alone to curb the fire risk posed by lithium-ion batteries.
"If you own a lithium-ion battery product, stop risking your life and your family's lives, make sure you follow the advice on how to charge and use these devices safely," he said.
The NSW State coroner in November announced a probe into fires sparked by lithium-ion batteries, after two people died in March when a battery exploded and caused a blaze north of Sydney.
Poor-quality or improperly charged lithium-ion batteries are susceptible to dangerous thermal runaway events, which occur when temperature outpaces energy dispersal.
