Battery found at deadly Sunset Park fire, days after Bronx blaze
A house fire in Brooklyn’s Sunset Park killed six people, and a lithium-ion battery was found at the scene; investigators have not yet determined the cause. The fire came a week after the Bronx e-bike fire at the Patterson Houses, and as the city’s Department of Consumer and Worker Protection reported inspecting more than 200 shops and issuing more than 130 violations for unsafe micromobility devices in August and September.

IAFF: what to know about the rise in lithium-ion battery fires
The IAFF links the New York deaths to a broader rise in residential battery fires across the U.S. and Canada and explains thermal runaway, noting that a failing cell can exceed 700°C, release toxic gases and reignite hours or days later. The union outlines its push for a national lithium-ion battery safety initiative in Canada and a mandatory U.S. federal standard for micromobility batteries, alongside practical charging, storage and disposal advice.

Toronto has recorded 124 lithium-ion battery fires so far in 2026, well above the previous record of 91 set in 2025. Ontario’s Solicitor General said the province will finalize regulations early next year banning modification of the batteries, a step Toronto Fire Chief Jim Jessop called a welcome “first step” that would give fire inspectors new enforcement powers.

Bronx e-bike battery fire at Patterson Houses: Mayor Mamdani and FDNY brief the public
At a press conference after the fire at 320 Morris Avenue in Mott Haven, officials said the FDNY had determined an e-bike’s lithium-ion battery was the cause, and that the bike blocked the apartment’s exit; an 11-year-old boy died and four others were critically injured (three later died, bringing the toll to four, according to subsequent IAFF and City Council reports). Fire Commissioner Lillian Bonsignore said the city had seen 401 lithium-ion battery fires so far in 2026, with 74 injuries and six deaths, and urged residents to charge and store e-bikes outdoors and never block exits.
