How to Identify the Capacity of the Battery

Battery Capacity Definitions
Identifying Capacity or Battery Run Time Using the Monitor
Revision A
Maintenance: Lithium-Ion Battery
Store the battery outside of the monitor at a temperature between 20°C
to 25°C (68°F to 77°F).
When the battery is stored inside a monitor that is powered by an AC
power source, the battery cell temperature increases by 10°C to 15°C
(50°F to 59°F) above the room's ambient temperature. This reduces
the life of the battery.
When the battery is stored inside a monitor that is continuously
powered by an AC power source and is not powered by battery on a
regular basis, the life of the battery may be less than 12 months. GE
recommends that you remove the battery and store it near the
monitor until it is needed for transport.
The following terms are used to define the capacity of the battery:
Design Capacity — The theoretical capacity of the battery cells when
the battery is new.
Full Charge Capacity — The actual amount of charge the battery can
store and deliver to the monitor.
Remaining Charge Capacity — The amount of Full Charge Capacity
currently remaining in the battery. This is a percent of Full Charge
Capacity.
One new, fully charged battery lasts about 2 hours. Two new, fully
charged batteries last about 4 hours. The battery capacity gauge icon
located in the lower right-hand corner of the display is the battery's "fuel
gauge." This gauge identifies the battery's current state of health and
charge status.

A battery that has 100% Design Capacity and is charged to 100% of this
capacity, lasts approximately 2 hours. However, as the Full Charge
Capacity declines, the approximate run time of a fully charged battery
will decrease.
