Thanks for that information.
<br>
Just a side question:
<br>
Will the ups.mfr.date value be updated automatically by the APC
ups firmware when I change the battery or will I need to set it
manually? I'm asking because I'm not sure if the current battery
was really installed at the time indicated by this field.

<br>
Where APC has provided a value for battery mfg date, it has always
been the same as the UPS mfg date. The value isn't automatically
updated and NUT doesn't (from what I've seen) provide a way to
update it manually.

I had to use apctest from the apcupsd suite to do that<br>

Before getting new batteries, you might want to check the float
voltage with a good multimeter. 55.65 is rather high (~2.32/cell),
but I wouldn't trust what the UPS says. Smart-UPS's can be bad
about overcharging their batteries. It can be adjusted by software
in some cases.

<blockquote type="cite">I also have another (maybe related)
problem. I have another 2 APC devices I'd like to monitor
(apparently same model and serial numbers). However, whenever I
connect a serial cable to the port on the UPS, the whole device
shuts down immediately. This happens only if I connect the other
end of the serial cable to either a ttyS0 port on a running
motherboard or a port on a rs232-to-usb adapter (even if the usb
end ISN'T connected to a NUT monitoring server). </blockquote>

my APC SmartUPS 1000 -<span class="st"><em>SU1000I</em> shuts down
the very instant I </span>connect it to my workstation using a
serial cable that I had handy ( received together with a switch ). I
guess that the incorrect wiring makes the UPS go nuts.<br>

<br>
This is obviously slightly off-topic because it doesn't seem to
be related to the nut ups drivers.
<br>
I'm just wondering what could be happening and if old batteries
on relatively high load (approx. 75%) could be a reason the UPS
shuts down abruptly on connecting a serial cable on both ends.
IT sounds really strange though.
<br>
Also, the UPS won't switch on while the serial cable is
connected even if I press the UPS power-on button several times.
<br>
I have to disconnect it (or at least the far end of it) in order
to "boot" the ups.

<br>
Are you using APC's supplied serial cable? They have special
wiring and it varies depending on UPS model.
