a voltage-control circuit operable to;
communicatively couple with and provide power to the ultrasonic-signal-generation assembly;
detect which one of the ultrasonic waveguide types is coupled to the handle;
provide a first output in response to a detection of a first waveguide type; and
provide at least a second output in response to a detection of at least a second waveguide type;
as the cordless battery assembly is removably inserted into the handle, coupling at least one of the plurality of connectors of the battery/handle interface with at least one of the connectors within the battery chamber to;
communicatively couple the voltage-control circuit to the ultrasonic-signal-generation assembly; and
provide power to the ultrasonic-signal-generation assembly;
detecting the waveguide type of the ultrasonic waveguide coupled to the handle with the voltage-control circuit; and
dependent upon the detected waveguide type, providing at the battery/handle interface one of;
the first output; and
the second output.

Abstract
A method for powering electrically powered surgical instruments includes removably inserting a cordless battery assembly into a handle thereof, the instrument handles having a battery chamber and different types. The battery assembly comprises an energy cell powering a signal generation assembly of the instruments. A battery/handle interface has connectors mating with connectors within the chamber. A voltage-control circuit is operable to communicate with and power the signal generation assembly, detect which handle type is connected to the battery assembly, and provide different outputs in response to a detection of the handle types. As the battery assembly is inserted, connectors of the battery/handle interface are coupled with connectors within the battery chamber to communicatively couple the voltage-control circuit to the signal generation assembly and provide power thereto. The connected handle is detected and dependent upon the detected handle type a different one of the outputs are provided.
