That's helpful, thanks.  tl;dr version:  An internal relay-controlled
array of transformers dials up the voltage, after an 8-33 ms lag, when
input feed drops -- making it up by drawing higher current.  Protracted
use in that mode generates a lot of excess heat, which will reduce
service life of the battery and associated parts, or UPS failure.
