A communication device comprises a processing circuit having at least two modes, a sleep mode and an awake mode, a wireless communications circuit that can wirelessly send a message as to whether an alarm has been triggered, and a passive sensor, powered by audio signals impinging on the passive sensor, that provides at least an approximation of an audio signal to the processing circuit so as to cause the processing circuit to switch between the at least two modes. The communication device can be housed in a housing sized to fit into a battery compartment.

A controlled battery includes a housing shaped in order to fit inside a battery compartment of an electrical device. The housing includes mechanical connectors on an exterior surface of the housing, adapted to couple to conventional battery electrical terminals of the electrical device. The controlled battery further includes an energy storage, such as a battery, inside the housing which stores energy and a voltage regulator which delivers a voltage to the mechanical connectors of the controlled battery from the energy storage, the voltage configured to be a consistent output voltage that does not deviate from a characteristic output voltage of the controlled battery until the energy storage is substantially depleted of energy.
