Zusammenfassung:	A surgical instrument includes a shaft assembly, a handle assembly including a battery dock, and a battery unit. The battery unit is configured to be received by the battery dock such that the battery unit is in electrical communication with at least one of the shaft assembly or the handle assembly. The battery unit includes a casing, an anode contact and a cathode contact within the casing, and a discharge drain. The discharge drain includes a controller, a switch element, and a resistor element operatively connected between the cathode contact and the anode contact. The controller is configured to selectively direct the switch element to close such that the resistor element is in electrical communication with the anode contact and the cathode contact. Thereby, the resistor element is configured to drain remaining electrical power from the at least one battery connected to the anode contact and the cathode contact.
