Firefighters responded at 9:42 a.m. Monday to a report of a fire at Endicott's iM3NY lithium ion-battery factory.

The factory had a piece of machinery on fire on its assembly line, the Endicott Fire Department was advised as it traveled to the scene. After firefighters arrived, they observed smoke, but no flames. Employees had dumped an extinguisher on the fire before exiting the building, according to Chief Joseph Griswold.

Firefighters stayed on the scene to disassemble the machinery and ensure the fire was out. No injuries were reported.

While the factory creates lithium-ion batteries, Griswold said the fire did not appear to be related to a battery. The cause of the fire -- along with the extent of damages -- remains unknown, although Griswold said he had "a feeling it's pretty expensive."
