According to my notes, it has been just over 4 years since I installed them. Looking at on-line sales, these seem to use batteries in a pre-packaged plastic shell. I don't recall if that's what's in my units or not.

I've replaced batteries in various APC battery trays without incident. 
It's not difficult to find the correct aftermarket batteries from 
sources such as Batteries Plus or Gruber Power.  The best of the lot was 
a 5U 3KVA unit that had fully-enclosed steel battery trays with their 
own wiring harness and hot-plug connector.  That UPS, sadly, was badly 
damaged in transport by a moving company who ignored specific instructions.

I moved away from the 3KVA APC rackmount units after the second 
SU3000RM3U in a row failed in the same dramatic way.  (The first just 
blew up an output transistor, the second did so so violently as to 
actually melt a hole in its mainboard.)

My current Cyberpower main UPS is another story.  Its battery "trays" 
are horrifying.  I have seen thicker, stronger plastic on blister packs 
at the supermarket.  I ended up resorting to strapping the battery packs 
together with duct tape.  The DSP-based HP unit between the APCs and the 
Cyberpower had a lot to like about it, but unfortunately it was deranged 
and would never come out of self-test until it was hard power-cycled.
