Nut upsuser - Dec 2009 - diff question, Belkin F6C100-4 this time

Greetings all;

I pulled a Belkin F6C100-4 into the shop this afternoon, deader than a door 
nail.  Out of service for about a year because (I'm assuming here) that the 
cooling fan stopped and cooked what little remaining life there may have been 
out of the batteries, which had swelled so badly I had to split its frame to 
get them out.  They are also in the under 1 volt per 12 volt pack charge 
state, which considering they are about 5 years old & it hasn't been
plugged
in for 18 months because it had failed & would not restart.

Looking over the circuitry, and playing Sherlock with the clues since I am a 
C.E.T., it appears that there is a relay in series with the line voltage 
input, which is driven by that section of the PCB that is connected only to 
the battery, and that without the batteries to supply 'starter' power,
it
will not enable the relay to power itself up.

Am I correct?

I took a chance and ordered some fresh batteries, but they probably will not 
arrive before 2010 now.  I'll also need to locate a new fan, as that one can
be turned by hand or air, but is certainly much too stiff to run under its 
assumed 12 volt dc supply.  No damaged parts can be seen on any of the
PCB's.

I am also disappointed to find the fan doesn't have a tach wire in its
hookup
that Belkin _could_ have used to trigger a power down when it failed, but 
obviously did not.  For a $375 (new in 2001 or 2) ) ups, I really expected 
more.  OTOH, those batteries I took out are the 3rd replacements (from Belkin 
at $225 a kit) I have put in it.  What I ordered were $87 with shipping.  I 
buy a lottery ticket about once a year too. ;-)

Can nut be trained to listen to this old boat (it weighs in at about 45 
pounds) anchor?  Serial only of course.

Referring to http://www.networkupstools.org/stable-hcl.html , there is  
a chance that one of these two drivers will talk to it:

  * http://new.networkupstools.org/man/belkinunv.html

I don't know enough about the model numbers to say whether yours might  
be an old -UNV series or not. (Some messages that I found with Google  
seem to indicate that -UNV models have a USB port as well as serial,  
so it might be completely different.)

The belkinunv man page talks about a related issue:

http://new.networkupstools.org/man/belkinunv.html#_soft_shutdown_workaround 
  (first paragraph)

It sounds like that model won't come back on if you tell it to shut  
down before the batteries are completely drained. I guess it depends  
whether your intended use case includes reliably starting back up  
after a power outage, or if you are more concerned with shutting down  
cleanly.
