I've a Belkin Regulator Pro (F6C1400-EUR) connected via serial to a
FreeBSD machine using NUT v.2.4.3
Sometimes I get a series of logged messages saying that the data is
switching between stale and valid, this in itself isn't an issue,
however occasionally when the communication is re-established, upsmon
gets a "On battery" message followed quickly by "Battery low" message,
and calls on the system to halt. I know for a fact that the battery
isn't low at any stage, as other UPSs have not reported a loss of power.
This behaviour has only started occurring since using NUT rather than
Belkin Bulldog (not supported on FreeBSD x64).

I can see no reason why the NUT is seeing a battery low message.
Unfortunately there is only a 5 minute resolution for the ups log:

Has anyone got any suggestions?
