Kaua‘i Fire Department discuss best practices for lithium-ion battery safety

As lithium-ion batteries continue to power an increasing number of tools and technologies, the Kauaʻi Fire Department reminds residents of best practices when handling these devices.

“Lithium-ion batteries store a large amount of energy in a small space,” said Kauaʻi Fire Department Chief Michael Gibson. “When these batteries overheat or fail, fires can spread rapidly and produce toxic off-gassing. Following a few basic safety steps can significantly reduce the risk. These are simple habits that protect your home.”

This message aligns with this year’s National Fire Prevention Week theme, which focused specifically on lithium-ion battery safety. However, the Kauaʻi Fire Department hopes to draw more attention to this responsibility because lithium-ion batteries are so widely used.

Common items such as cellphones, laptops, power tools, and portable chargers rely on these batteries, which play a role in nearly every aspect of daily life. While generally safe, they can become hazardous when damaged, improperly charged, or exposed to extreme temperatures.

To help reduce these risks, the Kauaʻi Fire Department encourages residents to purchase devices and replacement batteries from reputable manufacturers. Avoiding counterfeit and off-brand chargers also prevents overheating.

Products tested by nationally recognized laboratories meet important safety standards, and using the charger that comes with each device can greatly reduce the chances of malfunction.

Charging practices also make a significant difference. The Kauaʻi Fire Department recommends residents charge devices on hard, flat surfaces rather than on beds or couches, where heat can build up. Unplugging devices once they are fully charged, avoiding overnight charging when possible, and ensuring that batteries are charged at appropriate temperatures all contribute to safer use.

In addition to proper charging, thoughtful storage and handling help prevent problems. Batteries should be kept in cool, dry areas and should not be punctured, crushed, or left in hot vehicles. Any battery that appears swollen, damaged, or unusually warm should be replaced immediately.

Residents should also watch for warning signs such as unusual odors, popping sounds, leaking, or smoke, and call 911 immediately if a device begins smoking or burning.

Lastly, the Kauaʻi Fire Department urges the proper disposal of old or damaged batteries. Residents can drop off household batteries at the Kauaʻi Resource Center, 3460 Ahukini Road, in Līhuʻe during regular business hours.
