A Warriewood family has lost their home and beloved pet dog after a faulty e-bike battery sparked a fierce blaze on Tuesday morning.
The fire broke out at a property in Eucalyptus Place around 11.10am, with emergency services responding to multiple triple zero calls from concerned neighbours.
Fire and Rescue NSW investigators believe the lithium-ion battery, which had been charging in the home’s garage, was the source of the blaze. The family had reportedly noticed the battery wasn’t functioning properly in recent days, failing to hold its charge as it normally would.
Tragically, the two adults and two children who live at the property were away when the fire started, but their pet dog was inside. Firefighters discovered the animal suffering from smoke inhalation and attempted to revive it, but were unsuccessful.
Superintendent Adam Dewberry said the fire spread rapidly from the garage into the walls of the home before racing through the roof cavity. More than 20 firefighters from stations across the northern beaches – including Narrabeen, Mona Vale, Avalon, Dee Why and Manly – battled the blaze for over an hour before bringing it under control.
“The house was destroyed,” Superintendent Dewberry confirmed.
He said the family had persisted in trying to charge the malfunctioning battery despite its recent performance issues.
The incident marks the second e-bike battery fire in Sydney within two days, following a blaze at a Newtown property on Monday.
Fire and Rescue NSW has recorded approximately 80 fires linked to lithium-ion batteries from micro-mobility devices such as e-bikes and e-scooters across New South Wales this year.
Superintendent Dewberry issued an urgent warning to owners of such devices about the dangers of continuing to use faulty batteries.
“If the battery is not working correctly, do not keep using it,” he stressed. “Recycle it appropriately and get a new one and make sure that it’s the appropriate battery for your vehicle.”
The incident serves as a stark reminder of the fire risks associated with lithium-ion batteries, particularly when they show signs of deterioration or malfunction.
