Some UPSes provide a charge threshold so that the output of the UPS
does not turn on until after the batteries have charged to beyond,
say, 30%. If that threshold is adjustable (as I believe it is on
several MGE models), you can be reasonably sure that the UPS will have
enough runtime to allow the machine to boot to the point where NUT can
detect a future power failure.
Your scenario is definitely something to consider if the hardware does
not provide this option, however.
