My mistake - I misread that part of the code. In 2.6.0 and later, we
apply a scale factor of 0.1 to correct for that bug in the UPS firmware.

It's not supposed to, but I suspect another firmware bug.
"ups.alarm" is not meant to be parsed by any of the monitoring clients
such as upsmon, so if you know the battery is in fact installed (and
the voltage seems to confirm this), you can safely ignore that.
If it still bothers you, the proper thing for us to do is figure out
if your model truly can't tell if the battery is installed, or if it
is inverting the sense of that signal.
We would need two debug logs to compare - one with the battery
installed, and one without. Check your UPS documentation to be sure
that it is okay to pull the battery connector when things are powered
on. (This is pretty standard on high-end rack-mount UPSes, but might
not be the case for smaller ones.)
Stop the existing NUT setup, being sure that the usbhid-ups process
has died. Then run "/lib/nut/usbhid-ups -a ups -DD 2>&1 | tee /tmp/log-
battery-installed.txt". I think that's the path for your version of
Ubuntu, but in any case, no more than two -D flags should be
necessary. Let the driver run for a minute or two, then kill it via
Ctrl-C. Repeat with the battery removed.
Please gzip both logs before emailing them to the list. Thanks!
