put finger to keyboard and composed:

I have a Conext (by APC) model CNB-325 battery backup power supply (not
a real UPS) that shows funny voltages when the power cord is
disconnected.

Backup supply unplugged from AC outlet, computer used as load:

hot-neutral: 115 VAC
hot-ground: 58 VAC
neutral-ground: 58 VAC

The PC PSU has RF suppression (?) capacitors between A-E and N-E. If
the earth pin is disconnected, then its potential floats to a point
midway between A and N.
