Kaua‘i Fire Department reminds residents of best practices for
lithium-ion battery safety
LĪHU‘E – The Kaua‘i Fire Department is reminding residents to practice safe handling, charging, and storage of lithium-ion batteries as these devices continue to power an increasing number of tools and technologies in homes, vehicles, and workplaces.
“Lithium-ion batteries store a large amount of energy in a small space,” said Kaua‘i 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. KFD emphasizes that while Fire Prevention Week draws attention to these issues each October, effective prevention is a year-round responsibility shared by every household.
Because lithium-ion batteries are so widely used, residents may not always realize how many common items rely on them. From cell phones, laptops, tablets, and smart watches to e-bikes, e-scooters, drones, power tools, and portable chargers, these batteries 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, KFD encourages residents to purchase devices and replacement batteries from reputable manufacturers. 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. Avoiding counterfeit or off-brand chargers is another important step toward preventing overheating.
Charging practices also make a significant difference. KFD reminds residents to 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 right away. Residents should also watch for warning signs such as unusual odors, popping sounds, leaking, or smoke, and call 9-1-1 immediately if a device begins smoking or burning.
Lastly, KFD encourages proper disposal of old or damaged batteries. Drop off household batteries only at Kauai Resource Center, located at 3460 Ahukini Road in Līhu‘e, during regular business hours. For more information, visit the website at www.kauai.gov/batteryrecycling.
