1. A method comprising:

  • processing instructions stored in a computer readable memory that are executable for comparing charging records of each of a plurality of batteries that are individually useable to provide power toan electronic component further processing the instructions to select one of the batteries based on the comparing;

    further processing the instructions to electrically isolate the selected battery from all of the other batteries in the plurality and from the electronic component while still providing power to the electronic component from a source other than the selected battery; and

    further processing the instructions to instigate a battery power calibration procedure in relation to a hierarchy of calibration statuses ranging from a done status at the top of the hierarchy to a failed status at the bottom of the hierarchy and one or more other statuses in the hierarchy, the calibration procedure characterizing the selected battery as being calibrated or not calibrated by determining a time required to discharge the selected battery to a system load from a fully charged voltage to a preselected end-of-discharge voltage and comparing the determined discharge time to a predetermined fixed time range.
