Lithium-ion batteries power many household devices, but damaged batteries and unsafe charging practices can cause them to overheat, catch fire or explode.

Smartphones, tablets, laptops, headphones, e-cigarettes, toys, and power and lawn tools are among the products that commonly rely on these batteries. During Fire Prevention Week, residents are being urged to choose, charge and discard them carefully.

Before buying a battery-powered product, research it and check the product and packaging for a mark from a nationally recognized testing laboratory. That mark indicates the item meets established safety standards. Some products available online or in stores may not meet those standards, increasing the potential fire risk.

Use the charging cable supplied with the device and follow the manufacturer’s directions. If a replacement is needed, purchase one from the manufacturer or select a charger it has approved.

Devices should be charged on a hard surface—not beneath a pillow or on a bed or couch, where heat can build up and lead to a fire. Once a device is fully charged, unplug it or remove the battery rather than continuing to charge it.

Lithium-ion batteries should never go into household trash or standard recycling bins because they can ignite. Instead, take the device or battery to an appropriate battery-recycling location. Nearby collection sites can be found at call2recycle.org.

These batteries are part of daily life, but careful purchasing, charging and disposal can help prevent fires, property damage and fatal injuries.
