I found a schematic this morning at:

and then later found step-by-step instructions for doing a full-up conversion:

I should have thought of that conversion myself, which is simply adding a
germanium diode (1N34, 1N60) or a Schottky barrier diode (1N5711) in series
with the batteries to drop the voltage by 0.3V. That's a terribly simple
change and essentially requires no calibration.
