APC batteries look easy to replace, but I couldn't comment on their availability.
MDS Batteries has a range.
I've been using two APC SmartUPS 700 (SU700INET), with a serial cable. Gentoo, and FreeBSD before it could see it fine.
I initially had a problem running them against diesel generator power, but it turns out there is a switch at the back to make it less picky about its input supply.
