it's a SmartUPS 2200, s/h on eBay. That might not be a "big" UPS
by your standards, but it was by mine.

I've got a couple of those, both saved from being skipped and a 1400,
they're fairly "cold war" design, never see to go wrong. Last time I
replaced the batteries with 3rd party equivalents they seemed a
reasonable price, need doing again and the prices seem to have shot-up.
So for the past 3 months or so I've bypassed them - and noticed how much
power they consume just sitting there (cooking their batteries!).
