Lithium ion batteries supply power to many kinds of devices including smart phones, laptops, scooters, e-cigarettes, smoke alarms, toys, and even cars. Take care when using them. In rare cases, they can cause a fire or explosion.

The problem 

• These batteries store a large amount of energy in a small amount of space. 

• Sometimes batteries are not used the right way; batteries not designed for a specific use can be dangerous. 

• Like any product, a small number of these batteries are defective. They can overheat, catch fire, or explode.

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. 

• Keep batteries at room temperature. 

• Do not place batteries in direct sunlight or keep them in hot vehicles.

• Store batteries away from anything that can catch fire.

Signs of a Problem

Stop using the battery if you notice these problems: odor, change in color, 

too much heat, change in shape, leaking, odd noises. If it is safe to do so, move the device away from anything that can catch fire. Call 9-1-1.
