Simple test - while watching the reported status from the UPS, pull the plug :)

I had an UPS display similar issues, turned out the batteries were
pretty close to the end of their lives and the once 20 minute runtime
was down to a few minutes - just enough time to flag LB and for (most)
of the systems to shut down cleanly.

Certainly if the UPS itself is providing an audible LB signal then
it's unlikely that NUT caused an un-needed shutdown.

                 Please keep list traffic on the list.
