Lithium-Ion Battery Safety

BACKGROUND

Lithium-ion rechargeable batteries are commonly used in home electronics such as phones, laptop computers, tablets, e-scooters, and other devices requiring plug-in charging. These batteries are small and powerful, but when used incorrectly, they can overheat, catch fire, or explode. Fire agencies across California continue to respond to fires caused by lithium-ion batteries.

SAFETY TIPS

• Purchase and use devices that are listed by a qualified testing laboratory.
• Always follow the manufacturer’s instructions.
• Only use the battery that is designed for the device.
• Put batteries in the device the right way.
• Only use the charging cord that came with the device.
• Do not charge a device under your pillow, on your bed, or on a couch.
• Do not keep charging the device or device battery after it is fully charged.
• Plug directly into a wall electrical outlet for charging.
• Keep batteries at room temperature and away from heat or direct sunlight. Do not charge them at temperatures below 32°F (0°C) or above 105°F (40°C).
