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
(APC).

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 have one just like that on my TV and sat box and you can replace
that "battery pack" with 2 batteries of equal AH that end up being
about $40 less if you shop around.

I don't care about the price. My point is that there are far
more variations in batteries -- battery sizes and numbers thereof.
I have a UPS that takes *one* battery. Some two. Others 4.
At one point, I had one that took *10* of the 12V 7.2AHr units
(it was the size of a dishwasher).
