That's unfortunate, but we can probably work around that.

No, but what you could do, is pull the input plug and run 'upsc' again.
Normally, one would expect that the output on battery would be equal to
the nominal voltage the UPS was made for ('input.voltage.nominal'). I know
this is a string value read from the UPS, so there is no conversion
involved. So we can expect the output voltage on battery to be 230V and
see what 'output.voltage' is. This should give an idea how much off it is.
