I have this old Dell Dimension 2400 desktop with a printer. The cable

Anyway, it continues to work great. It forms the base of a network (I
have 2 laptops). I have had the desktop system for probably 10 years and
an APC UPS connected to it for maybe 8 years.

Finally, I am getting a message that the APC is about to give up the
ghost (fully charged, the battery has only 5 minutes of backup time).

Now, I guess I could just get a battery replacement, but I am thinking
I'd rather just get a new UPS.

So, any recommendations?

If you have the room you could do what I did. I had a good UPS that the
battery went on. It used a single AGM 12 volt unit and gave you around
20 minutes to shut down. Instead of buying the same battery I decided to
add some extra capacity. Removed the old battery routed the battery
connections to terminals on the outside of the box and connected up a
marine battery. It sets in a battery box with a vent to the outside and
is also connected to an external charger that has a solar back-up. With
the big battery I can count on a LOT more time (the same make/model runs
the trolling motor on my boat for 12-18 hours and that takes far more
power to run)

There's a big fire hazard with low voltage batteries in case of a short
circuit. Fuse the circuit at the battery (it's likely to have to be
a pretty big amperage fuse), and use only wires capable of carrying
that amperage.

The wires carry ten times more current than what you're used to with
household stuff at 110v, for the same wattage. You need much thicker
wires. The fuse has to blow before the wires heat up.

In case of need for emergency long term power, I'd put the battery and
inverter outdoors and run only 110v indoors with an extension
cord.
