ROME — After a pair of structure fires in recent months caused by lithium-ion battery failure, the Rome Fire Department has some words of warning to people using these types of batteries in their electronic devices and home gadgets.

“It’s a known issue around the country,” warned Rome Fire Chief Thomas Iacovissi.

Fire officials said that lithium-ion batteries store a large amount of energy in a small amount of space. And if these batteries are not used properly, and not used for the device they are specifically designed for, it can lead to energy flare ups that quickly ignite. Officials said there is also a problem if the battery charger is of an off-brand, or not the charger specifically designed to go with that device or battery.

“Sometimes, maybe if you buy a cheaper model, you’ll have an issue,” Iacovissi stated. “Or if there is physical damage to the battery that you don’t even realize.”

Like any product, fire officials officials said there is a chance it could simply be defective, which can also cause the battery to overheat, catch on fire or explode.

“When they fail, they fail instantly,” the chief warned.

“It overheats, and once it gets to a certain point, there’s no stopping it. There’s really no notice when it happens, it just happens.”

Lithium-ion batteries caused fires at CRC Raceway & Hobby in Rome on July 13, and then at a home on Carroll Street on Sept. 18. In the Carroll Street house fire, officials said the battery was left charging in the basement, leading to the fire.

Chief Iacovissi said that these batteries will “flare up and stay flared” for a period of time, at which point they can catch curtains, furniture or other flammables nearby items on fire.

Meanwhile, in New York City, the Attorney General’s Office has issued a warning about the lithium-ion batteries used in e-bikes, e-scooters and hoverboards. Officials said battery issues led to four deaths and 79 injuries in New York City in 2021.

“E-bikes are a valuable resource for many hard-working New Yorkers, but they can carry safety risks if not used properly,” said Attorney General Letitia James in a release.

“That is exactly why it is so important that they are used carefully. While it can be tempting to search for deals or overlook problems, no convenience is worth your safety or your life. Taking all proper precautions can protect yourself, your family, your property, and everyone around you.”

Safety tips:

• Purchase and use devices that are listed by a qualified testing laboratory.
• Always follow the manufacturer’s instructions.
• Only use the battery that is designed for the device.
• Put batteries in the device the right way.
• Only use the charging cord that came with the device.
• Do not charge a device under your pillow, on your bed or on a couch.
• Keep batteries at room temperature.
• Do not place batteries in direct sunlight or keep them in hot vehicles.
• Store batteries away from anything that can catch fire.

Rome fire officials warned to stop using the battery if you notice these problems: odor, change in color, too much heat, change in shape, leaking or odd noises. If it is safe to do so, move the device away from anything that can catch fire. And call 911 in an emergency.

In order to properly dispose of batteries, fire officials warn against putting them in the garbage, where they could continue to be a problem. Likewise, do not put discarded batteries into a pile.

Recycling batteries is the best option, officials said. Take them to a battery recycling location or contact the Oneida-Herkimer Solid Waste Authority.
