The FDNY releases PSA on serious risks posed by home-based lithium-ion battery workshops

August 28, 2025

In a newly released Public Service Announcement (PSA), the FDNY is warning New Yorkers that home-based lithium-ion battery workshops pose serious fire risks. 

On Aug. 17, the FDNY uncovered a battery repair workshop in Queens after a fire was reported in the cellar of a home. FDNY units found approximately 100 lithium-ion batteries burning when they arrived to the scene. Multiple micromobility devices and lithium-ion batteries were found in various states of disassembly and disrepair.

At another incident, this time on Aug. 26 in the Bronx, the FDNY responded to a basement fire. Upon arrival, members discovered multiple lithium-ion batteries and devices that were being worked on at the location.

"When batteries are tampered with, improperly stored, or uncertified, they become ticking time bombs that endanger not only families and neighbors but also the first responders who rush to save them. Worse yet—they're illegal," FDNY Commissioner Robert S. Tucker said. "The FDNY will continue holding those responsible for creating these dangerous conditions accountable."

Building, tampering with or attempting to repair lithium-ion batteries is extremely dangerous and can ignite fast, destructive and potentially deadly fires, putting the public and first responders at risk. 

If you see such activity, report it promptly to the FDNY by calling 311 or 212‑NEW‑YORK (212-639-9675).

"We need every New Yorker to do their part—buy only certified batteries, never attempt makeshift repairs, and report unsafe conditions before tragedy strikes," Chief Fire Marshal Daniel Flynn said. "Together, we can prevent these dangerous fires and keep our communities safe."

The Department's PSA program is made possible in part with support from the FDNY Foundation, the official nonprofit organization of the Department.
