I have similar issue with APC smart-UPS X1500.
I used a workaround to fix this issue. You can look into this.
A detail of the workaround is available at:

Just to throw in a couple of comments but no direct knowledge:
As for restoring immediately I believe the battery level has some effect
Determining the command is a little more tricky. The best way to do this
to sniff the connection since the manufacture does not make the commands
available. And to do this you need the UPS. So, since you have the UPS,
you can hook the UPS back up to the Windows box. Run it with a sniffer
the USB connection. Then see what commands are being sent, so that can
compared to what NUT is actually sending.
Haven't actually done this on USB myself but there appears to be a
of free sniffers out there. There is one that has a fully functional 33
trial that work on any 32 bit Windows, usblyzer. Search Google for:
