Many of the electronic devices we use every day – phones, laptops, power tools, electric bikes and toothbrushes – rely on lithium-ion batteries. If you use any of these battery-powered items, you will want to make sure you know the signs that the battery could be faulty or failing. Following are signs that the Electrical Safety Foundation says could mean there is something wrong with a lithium-ion battery: 

• The battery color changes. 

• A “sweet” electrical burning smell is emitted from the battery. 

• The battery is making noises or leaking fluid. 

• The shape of the battery device has changed. 

• There is smoke coming from the battery. 

If you detect a problem with a battery and it’s safe to do so, move it away from any buildings and, if possible, place it in a fireproof container.   

If a battery fire occurs, evacuate the area. Damaged batteries may explode. Also, alert others about any battery fires and call 911 for help.
