The handful that I've had (all APC, so ... "meh") are all 5-10 years old
at this point, and on their second or third set of batteries (3 year replacements, on average; so the 5YO one is nearing the "replace the
battery" threshold). One is probably closer to 15, come to think
of it ... but lightly loaded, so has only needed two replacements (~6
years on the replacements)
I don't particularly baby them (though do try to keep them down to about
75% of their rated capacity), but the power coming in isn't all that "bad(tm)" either; which probably helps.

APCs tend to be pretty ubiquitous, but they don't seem to be particularly high quality (even the larger, more upscale units).
OTOH, given our relatively infrequent outages, perhaps its time to
just switch to "switched outlet strips", instead? And, grumble about
the occasional "flicker"? (most of my machines can bridge brief outages
on their internal power supplies)
Or, deploy the even larger units to handle multiple loads?
(sigh) More frigging work...

An n=1 anecdote :-). I bought a 550 VA APC UPS in 2015, in 2022 it started beeping that the battery was low so I replaced it but the unit still beeped. Wouldn't charge the new battery, tried various things including charging the battery separately and reinstalling it but no joy. The manual said there was no reset function, it should just come back to life when the new battery was plugged in The old battery still tested ok, down some capacity but not dead, so I gave up and bought a 600 VA APC and it's still going after 2 years.
Room lights flicker maybe 2-3 times a year and go completely off long enough to annoy the microwave clock every couple of years so pretty clean power here. The battery spends it's entire life just floating fully charged. Don't know how long it would last if it was being cycled frequently.

The APC's I've had never died. Only the triplites 500va unit seems to grenade.
Now the replacement batteries are another story.
