ABSTRACT:
A system and method for managing battery slump in a battery-powered communications device including: an input configured for receiving battery voltage level information; an output configured for sending a signal for terminating a transmission; and a controller connected to the input and the output and configured to receive the battery voltage level information from the input; monitor the battery voltage level information; and send a signal via the output to terminate a transmission if the battery voltage level information crosses a predetermined threshold during the transmission. In particular, the system and method may further include an input connected to the controller and configured for receiving a signal indicating when a transmission is beginning or occurring and the controller is further configured to receive and monitor the battery voltage level information only when the transmission is occurring.
