PLEASE NOTE : Lithium-Ion batteries continue to slowly discharge (self-discharge) when not in use or while in storage. You need to routinely check the charge status of the battery.

The typical estimated life of a Lithium-Ion battery is about two to three years, or 300 to 500 charge cycles, whichever occurs first. One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again.
