Abstract
Various embodiments of systems, methods and apparatus are provided for indicating to a user a low battery condition of a remote control for a controlled device. More particularly, a remote control detects a low battery condition as well as the replacement of batteries in the remote control. The remote control transmits a low battery message to a controlled device responsive to detecting a low battery condition. Similarly, the remote control transmits a battery status message to the controlled device responsive to detecting the replacement of batteries in the remote control. The controlled device utilizes the low battery message and the battery status message to determine whether to present a low battery indicator to a user regarding a low battery condition of the remote control.
