Battery Pack
The computer uses a single high-capacity Lithium-
Ion smart battery pack that gives you longer use
between charges. The battery pack includes the
following features:
q Lithium-Ion Technology. Lithium-ion
technology does not have the memory-effect
problem of nickel–cadmium (NiCd) batteries,
nor the temperature problem of nickel–metal–
hydride (NiMH) batteries. Lithium ion
batteries consistently provide the longest
battery life and the best solution for road
warriors.
q Battery Gauge. The battery pack contains a
built-in gauge that allows you to check the
battery charge level even when the battery is
not installed inside the computer.
q Battery-Low Warning. When the battery
charge level becomes low, the battery
indicator flashes at regular intervals, warning
you that the battery pack’s power is low and
needs to be recharged.
