Maintenance Guide
Although uncommon, Lithium-Ion batteries can be com-
bustible, or will leak fluids when not properly maintained,
charged and/or stored. All Lithium-Ion Rechargeable
Batteries require routine maintenance and care in their use
and handling. Read and follow the guidelines to safely use
Lithium-Ion batteries and maximize your battery’s life span.
Overview
DO NOT leave batteries unused for extended periods of time,
either in the product or in storage. When a battery has been
unused for 6 months, check the charge status and charge or
dispose of the battery as appropriate.
The typical estimated life of a Lithium-Ion battery is about
two(2) to three(3) 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
LITHIUM-ION BATTERIES ARE COMBUS-
TIBLE. READ THIS MANUAL FOR PROPER
MAINTENANCE, CARE AND DISPOSAL.
