1. A method of managing the supply of power to an output circuit of an implantable hearing prosthesis comprising a voltage converter circuit and a plurality of rechargeable batteries, the method comprising the steps of:

  • converting, with the voltage converter circuit, a supply voltage to a battery voltage;

    selectively connecting, using a switch matrix, a desired one of the batteries to the voltage converter circuit;

    charging the desired one of the batteries based on information on each of the batteries stored in a register;

    selectively connecting, based on the information on each of the batteries stored in the register and using the switch matrix, a selected one of the batteries to the voltage converter circuit to enable the selected one of the batteries to be discharged through the output circuit; and

    converting, with the voltage converter circuit, the voltage output from the selected one of the batteries to a voltage for use by the output circuit.
