The shutdown test as you suggested. Except for a little modification:
I pulled the RS-232 cable from the original UPS to keep everything
running and connected it to a spare one - same model though.

The lamp connected to the UPS was lit all the time.

First I ran with something that consumed too little power for about five
minutes. Then I added load up to 80 VA and ran with that load for
another five and a half minutes. The spare UPS was stored disconnected
for at least half a year, it was cold and it said 90% battery when I
connected the RS-232 cable.

The issue is that I had to switch from Solaris to FreeBSD because of
increased license costs; I don't think I can fix that. ;-)

I'll try to do that in about 2 weeks.
