It sounds as though the UPS will support the load for 60min without its being connected to the power supply. Does that make sense, given the context in which the statement is made?

PWSlack is correct (as usual).

That search took all of 30 seconds. You should try it sometime - before posting.

How difficult can it be to apply some simple logic here???

Or, as you say, discover the answer on one's own.

Maybe ask a teenager, he'll know.

Autonomy

Also known as back up or discharge time, battery autonomy is a measure of the time for which the battery will support the critical load during a mains failure. Autonomy is a function of battery charge state, capacity and load size.

That wasn't too tough, was it?
