Last night in North Park turned tense when a scooter's lithium battery caught fire while charging and set a single-family home ablaze, according to fire officials. The blaze broke out shortly after 8 p.m. on the 3500 block of Florida Street and pulled multiple San Diego Fire-Rescue units into the neighborhood. Five people were inside at the time, and all made it out without injury, though firefighters later reported heavy soot inside and visible damage to the roof.
Investigators with San Diego Fire-Rescue concluded that the fire started in a lithium-ion battery for a scooter that was plugged in and charging inside the home, FOX5 San Diego reported. Crews were dispatched to the 3500 block of Florida Street and brought the flames under control after knocking down the main body of fire. Officials told FOX5 that nearby homes did not have to be evacuated and that the full scope of the property damage was still being assessed.
Why lithium batteries are a growing risk
Lithium-ion batteries - especially the larger packs used in e-bikes and scooters - store far more energy than the small batteries in phones and can ignite suddenly if they are damaged, overcharged, or used with uncertified chargers. Consumer Reports and safety researchers note that incidents involving micromobility batteries have been rising in recent years. The Fire Safety Research Institute, citing UL Solutions data, points to hundreds of battery explosions and thousands of fires since 2022. That trend has pushed fire departments to repeatedly warn residents to take extra care when charging and storing high-capacity batteries at home.
How crews handle battery fires
When lithium batteries ignite, firefighters sometimes call in hazardous-materials teams and switch up their usual playbook, since battery cells can re-ignite and produce toxic smoke that complicates fire suppression. Coverage of similar incidents notes that crews may ventilate buildings, use thermal imaging to hunt for lingering hot spots, and, in some cases, allow battery packs to burn under controlled conditions while they protect nearby property. FireRescue1 reports that these tactics have become more common as battery-related calls continue to pile up.
Safety steps for residents
Fire officials and safety advocates recommend several basic precautions: charge batteries on non-flammable surfaces, stick with the manufacturer’s charger, avoid overnight or unattended charging, and keep large battery packs away from bedrooms and exit routes. The City of San Diego has incorporated lithium-ion battery safety into its recent fire prevention outreach, offering guidance on charging and disposal to reduce residential risk. The San Diego Fire-Rescue news center and national safety resources feature checklists and tips for dealing with older, damaged, or swollen batteries.
Neighbors documented the scene on local message boards as firefighters worked into the night, with one thread on Reddit's r/sandiego showing heavy smoke and a cluster of emergency vehicles near Balboa Park. Users on r/sandiego also noted that power to the immediate block appeared to be cut while crews remained on scene. Investigators are expected to release a more detailed report after they finish assessing the damage and complete their origin-and-cause investigation.
