Alas, our experience differs by a wide margin too. You seem to be a
bit of a hobbyist. When you've serviced thousands of 'modern'
machines, get back to me.

Even though my own machines are ancient, the ones I work on for friends
are typically new.
Some of the people I deal with are gamers and have to have the latest
and greatest.

I've looked at some of those games, and other than visual effects,
graphics and sound, seem to be little different from those old DOS
games. LOL


Until Win10 came out, most of my more recent jobs were on Win8 machines
and confused owners. Once I put on Classic Shell, the folks stopped
crying. (One woman literally came over in tears because she could not
use her new computer.)

I have probably repaired more machines that you have...I don't know...
but I literally have repaired or built thousands of machines.
I've been doing this for about 17 years and at one time had two or three
machines on the the bench at a time.

FWIW: Thanks to getting surplus equipment from work, I have all on one
of several UPS...industrial grade.

Here are the batteries from my main UPS

Now for a UPS battery bank that is JUST PLAIN SCARY. Get some proper
connection cables on that thing!!! And ballance you banks, for crying
out loud!! Your series-parallel connections with an odd number of
mismatched batteries is ridiculous.



That's and old photo , so that particular setup was retired


however...it was a 12v system and all those batteries were in parallel.


In parallel the battery ampere-hours do not have to match but in this
case they did. That said, all the amp. hours of the batteries were the
same...just different manufacturers.

I probably had seven days of backup power there and if I ever would have
discharged them I would have had to use an auxiliary charger.


In my workshop I now have one, 48V UPS and a 24V UPS

The batteries even match. All in all I have a total of five UPS systems
installed.


Since I have some lights on the UPS too, most of the time we have a
power failure I never even notice .

It is very rare to have a power failure more than a few hours, but we
once had one 24 hours, I operated my computer as much as I wanted, but
did have to go out for coffee.



What are you charging it with? and what kind of UPS is it? How long
does it take to recover after a power outage? It appears to be a 24
volt system - my small one is 48 volts and the big one is 60 volts.
(Powerware Prestige EXT) Both are dual conversion.


The one in the photo was manufactured by Best, now out of business.

It used a ferroresonant transformer so even though it was a single
conversion there was not one instant of drop out.


The only dual conversion UPS Ihad bit the dust about a year ago....it
was quite ancient.

The little one on my wife's system is a 24, and the one backing up my
internet modem and VOIP is a 12. Each of my TV cable boxes/pvrs are on
their own UPS as well.

They are all good for about half an hour, but for long-term outages
the natural gas option on my generator provides for virtually
unlimited run-time.



No generator here, the one 24 hour failure we had was an very odd situation
