Lithium-Ion Battery Safety
Lithium-ion batteries are used in lots of products, such as mobile phones, laptops, electric vehicles, and generators. The use of these batteries is generally safe, and most have built-in safety features. Unfortunately, in rare cases, these batteries can overheat, catch fire, or explode.
Here is some basic safety information about lithium-ion batteries:
Reasons a Battery May Fail
Overcharging – If a lithium-ion battery becomes overcharged, the battery can rupture, overheat, catch fire, or explode.
Hot and Cold Temperatures – Extreme cold and heat can affect a battery’s ability to charge properly. The battery should be in moderate temperature conditions before charging.
Impacts – Impacts that could cause dents or punctures in the battery may result in dangerous charging situations, including overheating, fire, or explosion.
Tips for Safe Battery Charging and Use
- Carefully read and follow all manufacturer instructions and warnings.
- If at any time you witness a battery starting to balloon, swell up, smoke, or overheat, discontinue use and charging immediately.
- Avoid leaving a charging battery unattended.
- Use the power adapter meant for use with your specific product.
