I have lots of LED portable lights here and we have the standard
"emergency light" you see in commercial installations in the hall. I
swapped out the sealed beams for smaller LED lights and I imagine they
will run for days on those gel batteries. I do have a switch on them
so they can be turned off. That is handy if the power drops at night
and you are suddenly in the dark.

I have an old UPS that won't put out enough current for a PC, but works
OK with a string of LED holiday lights I have in the hall.

I call these "Lilly's lights" after a cat I used to have who slept in
the hall and didn't want to be stepped on. That cat is gone now, but
they make good emergency lights. There was a short (44 min.) power
outage this morning and they worked.

A battery will usually fix those "Bad" UPSs. They are not horribly
expensive online. That is why I have so many units around here. They
all came with bad batteries for free. I still have a few dead soldiers
back in my shop but I am UPSed out here. ;-)
There only seems to be 2 basic sizes with either 1 or 2 in each UPS

That's only for the smaller, consumer-ish units -- 12V 7.2AHr batteries.

I have a couple of these:
Which take the battery pack:

I took a pass on a pair of these:
because they require *two* of the above battery packs (the bottom
compartment is all battery)

The unit I've set aside for my network switch uses this:

I'm not keen on throwing lots of money into batteries in the hope that
they'll NOT be needed!

(APC is also notorious for floating the batteries at too high of a cell
voltage and prematurely cooking them! But, that appears to be their
business model -- sort of like toilet paper salesmen giving out
free prune juice samples...)
