From powering our smartphones, laptops, power tools, and toys to electric vehicles, scooters, even wheelchairs; Lithium-ion batteries are now part of the everyday technology we all use. But unfortunately, these revolutionary batteries can be incredibly dangerous because they have the potential to ignite and explode within seconds, leaving you with little to no time to react.  

Just this summer an e-bike battery caused a fire at a barbershop in Spring Valley. In the last six months there’s been about half a dozen incidents involving lithium-ion batteries. 

Failures are due to several factors one of which is overcharging or overheating, referred to as a thermal runaway. When the battery is overheated, it can cause a chain reaction which leads to a rapid increase in temperature and potentially result in a fire or explosion.  

Sometimes failures are simply due to manufacturing defects, a result of mass production. Even the smallest defect in manufacturing can lead to a hazardous situation. Other failures are simply caused from aging, resulting in a gradual loss of capacity and performance, leaving the batteries more susceptible to overheating and failure.

Our Fire & Emergency Services urges families to: 

• Not use off-brand products
• Follow manufacturer guidelines for charging
• Keep away from hot surfaces & flammable materials
• Look for Underwriter Laboratories, or UL, Certified products
• Stop charging if item feels hot to the touch

As a former police commander, I am urging our families and residents to be mindful of these batteries both during usage and disposal. In fact, there have been instances of these batteries starting fires in garbage trucks. 

These items should never be thrown away in the trash or recycling. They must be recycled by the Rockland County Household Hazardous Waste Facility in Pomona located at 35 Firemen’s Memorial Dr, Pomona which you can reach at 845-354-0783. 

I applaud our Fire and Emergency services staff, including Director Chris Kear, who provided an incredibly informative safety demonstration for local media, hoping to spread the word to families who might receive gifts powered by the lithium-ion batteries this holiday season. 

We urge our residents to do what you can to be safe and be sure any items that use these batteries are handled with caution and care.
