Replace the battery, I'd say.
Probably so, but it's less than a year old so I'm ignoring it as a form
of subtle punishment.
While UPS batteries don't last forever, I think with one that's
unable to hold a charge after less than a year you have a good case
for a warranty claim.
You may have a claim for replacement even if the warranty has
expired, on the grounds that the battery was not "merchantable". But >following up on that claim could be difficult and frustrating.

The CyberPower monitoring software says everything is fine.

The Cyberpower could record the discharge behavior on the last
protection run. Using that info, it could give a much better
estimate of how much capacity the unit has, when it is "charged".
To be feeding out the "optimistic value" all the time, that's
more than disingenuous.
UPSes have a self test they do on the battery once a day. When
you fail that, the UPS may "beep once", indicating the battery is
knackered. But the battery impedance test, the "fail" on that test,
is well past the "my battery isn't lasting even 2 minutes" mark. As
a user, simply observing how the battery handles a load on a
recent test, you can tell the battery is cooked and needs replacing.
It will be a while before yours fails the self-test, but by the
time that happens, you'll be sick of your "useless" UPS by then :-)
At this point, it's easiest to just do nothing but be annoyed.
I read somewhere that these things work great for propping up a router, modem, access point, etc. Not all of those things at once, though, and definitely not a desktop PC, which was my reason for buying it in the
first place.

When I first saw the claim of extended runtime, I was pretty happy with
my purchase, but when the power went out and the system shut down my happiness changed to disappointment and then annoyance.

Maybe some day they'll design the UPS properly.
The UPS just don't seem to take good care of the battery.
It's either that, or the battery is really really shitty
(thin plates). You would want the old battery and the
new battery to have the same weight, as a measure of quality.
Bad batteries last two years. Good ones claim to last four.
But many UPS overcharge the batteries so that they dry out. They have a constant trickle current maybe too high.

My brother-in-law kept an old motorcycle until he got dementia and
had to reduce his circumstances. He kept it in a garage for many months
at a time, connected to a tricle charger. Do the trickle chargers have
smats, like periodically letting the charge down to 90% before topping
up?
For my suggestion of wiring together
- a 12 V deep-cycle marine battery
- a trickle charger
- a 300W 12V->110V inverter
... should we put a timer clock in front so that the whole assembly only connects to the power outlet for 15 minutes per day? (I think the
mechanical timer clocks only can set a 24-hour schedule.)
It is not impossible, but the critical specification is never given: >Watt-hours. To do what you want, you need about 1000 Wh. That is about
what a good-sized car battery holds, i.e. buy a deep-cycle marine grade
12 V battery, a trickle charger and a 300W inverter. It is ugly, but
it should work to keep a laptop going for a day. If you need more, add
more batteries.
