Abstract
A battery charger (102) includes an input terminal (124) for receiving control signals from radio (104). The control signals are received by a charge controller (112) which provides a charge rate to radio battery pack (106) which is a function of the control signal. Radio (104) includes a controller (126) which can sense the state of the radio battery pack (106), as well as changes in the state of radio (104). Controller (126) can then modify the control signal sent to charger (102) and therefor the battery charge rate proved by charger (102) based on certain changes in the state of battery pack (106) or radio (104).
