NATCHITOCHES, La. — Safety experts are raising concerns about the increasing number of fires linked to lithium-ion batteries used in everyday consumer products.

More than 450 fires have been connected to lithium-ion battery power sources during the past 18 months, according to recent reports.

Lithium-ion batteries are commonly used in smartphones, tablets, electric vehicles, e-bikes, cordless power tools, digital cameras and drones. Experts say the batteries can generate extreme heat when damaged or improperly charged, with temperatures reaching as high as 400 degrees Celsius.

When a battery fails uncontrollably, the resulting heat can ignite flammable and toxic gases released from battery components.

Consumers are encouraged to follow manufacturer safety recommendations, avoid using damaged batteries and chargers, and properly dispose of worn-out battery packs.
