1. A battery-powered, modular surgical device, comprising:

  • an electrically powered surgical instrument interfacing with bodily tissue during surgery and requiring a pre-determined minimum amount of electrical energy to power the surgical instrument completely through a surgical procedure; and

    a power module assembly having;

    at least one modular battery supplying power for the surgical instrument during use and having a current state of electrical charge; and

    a control circuit electrically coupled to the at least one modular battery and to the surgical instrument and comprising a memory and at least one microprocessor;

    the memory storing data regarding the pre-determined minimum amount of electrical energy; and

    the microprocessor being programmed;

    to monitor and determine the current state of electrical charge of the at least one modular battery;

    to compare the current state of electrical charge of the at least one modular battery to the pre-determined minimum amount of electrical energy;

    to permit the battery to discharge if the current state of electrical charge of the battery is above the pre-determined minimum amount of electrical energy; and

    to maintain the battery in a non-discharge state if the current state of electrical charge of the battery is below the pre-determined minimum amount of electrical energy.
