UPS hold quick transfer
The UPS ought to be rated contained by KW/hrs. For one that's rated at 1K Watt/hr, that's 1000 Watts for an hour, or 100 Watts for 10 hours, or 500 Watts for 2 hours, you see the shape hopefully.
Rating of UPS in KW/hr x 1000 / watt usage = hours of operation
As an example, if my UPS is rate at 2Kwatt/hr and my TV uses 150Watts, then it's 2 x 1000 / 150 = 13.33 hours of operation
