We have a BackUPS Pro 1000, rated at 1000VA, maximum load 670W. The literature claims typical on battery runtime would be 9 min for a 700VA load, (500W x 1.4 = 700VA). We've never run it down, however, so I don't know what it really does. The power's only been off long enough to matter once, and after five minutes we manually shut everything down. We use it primarily for bridging short glitches, obviously. -- Gary Aitken garya@ics.com (business) garya@dreamchaser.org (personal)
