1. A battery comprising:

  • a) a first rechargeable battery cell, the cell having a number of replaceable sub-cells;

    b) sensors for measuring certain conditions of the sub-cells, including voltages, currents and temperatures;

    c) an output switching device coupled to the sub-cells, wherein the output switching device is operable, responsive to a first control signal, to selectively switch on a conductive path to a load from selected ones of the sub-cells;

    d) an input switching device coupled to the sub-cells, wherein the input switching device is operable, responsive to a second control signal, to selectively switch on a conductive path to a source from selected ones of the sub-cells; and

    e) logic circuitry coupled to the sensors and the input and output switching devices operable to automatically assert the control signals responsive to the measured conditions for switching a selected at least one of the sub-cells to supply the load and at least one of the sub-cells to recharge from the source.
