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. Use a
two to three year life expectancy for batteries that do not run through complete
charge cycles.
Rechargeable Lithium-Ion batteries have a limited life and will gradually lose
their capacity to hold a charge. This loss of capacity (aging) is irreversible. As
the battery loses capacity, the length of time it will power the product (run time)
decreases.
Lithium-Ion batteries continue to slowly discharge (self-discharge) when not in
use or while in storage. Routinely check the battery’s charge status. The product
user manual typically includes information on how to check battery status, as
well as battery charging instructions.
