The Battery pack contains protection circuitry, and a fuel gauge IC with internal memory to store pack
configuration information, measurement calibration, coefficients, manufacturer's information, and
chemistry data.

transport the system without having complete Power Off/On cycle.
In addition, the Battery enables fast return to scanning when AC power is resumed.
NOTE: The system cannot scan while AC power is not present.
