1. A battery pack configured for receiving inductive energy for charging a battery, comprising:

  • a processor unit for processing computer readable data relevant to receiving the inductive energy and for processing data communications with a computer system, wherein the processor unit is programmed to operate in a polling listening mode;

    a pickup coil controlled by the processor unit to receive an inductive data communication by listening for an inductive source to alternate between an energized state and a de-energized stage at regular intervals while in the polling listening mode and configured for receiving the inductive energy;

    a charger operatively coupled to the processor unit and the pick-up coil, the charger configured to output a direct current powered by the inductive energy and relevant to the inductive data communication; and

    a battery configured for receiving the direct current.
