Lithium Ion batteries can be potentially dangerous if they are not handled properly.

Venting is rare but can occur with ANY lithium ion battery regardless of safe chemistry or protection circuitry. Cell phones, laptops, PV’s and several other daily used items all use LIon batteries and have all been known to vent. Don’t believe us ? You Tube it.

Be sure to inspect your batteries regularly for tears in label or any abnormal appearance/ activity.

If your LIon battery gets excessively hot remove it from the device if it is quickly accessible and place the battery outside. If the batteries cannot be accessed easily, Power down your device and place it outside until it cools completely.

NEVER leave batteries unattended while charging!

Safe Battery Usage Tips->

Always insert your batteries properly into the device or charger. Typically the flat side of the battery faces the spring in your device.

Double check and clearly mark the positive side on your charger. Inserting batteries into the charger the wrong way can result in venting.

Always carry your batteries in a case or bag. NEVER carry loose batteries in your pockets or purse.
