How old are these UPS devices? How old are the batteries?
Are these "smart UPS"? Are they connected to a host computer via a communications cable? If so, how is the associated software configured to shut down the computers?
Did these UPS ever work correctly, or as expected?
Can you give us a couple examples of specific UPS and the hardware connected to them?
With a decent load on the UPS (a 150W light bulb, for example), what happens when you pull the plug?
