Abstract: A method and apparatus for determining whether to enable a functionality of a battery powered device upon connection to a battery is embodied by providing at least one voltage threshold in a memory of the battery that corresponds to a usable operating range limit of the battery and that is accessible by the battery powered device. Upon connection to the battery, the battery powered device acquires the voltage threshold or thresholds from the battery and programs itself with the threshold or thresholds. The battery powered device then compares a voltage of the battery to the threshold or threshold to determine whether the enable the functionality.

Abstract: A method and apparatus for adjusting transmission power in a portable two-way radio device allows the device to determine an expected battery voltage drop for a subsequent transmit event, based on present transmit power settings and battery impedance, and change the power setting for the subsequent transmit event if the battery voltage is likely to drop below a shutdown threshold at the present power setting or if the expected battery voltage drop will cause the battery voltage to be substantially above the shutdown voltage level and the present power setting is below an optimal level.
