This video explains how to calculate your approximate battery backup time for certain Battery Backup Power, Inc. UPS systems in 2 easy steps. 

Step 1: Enter your electrical load in watts.

Step 2: Use the drop down menu to browse the estimated backup time for the watt load you entered on Step 1 on different UPS models.

The calculator (see below) used in the video takes into account factors such as battery voltage, amp hour rating of batteries, DC BUS voltage, inverter efficiency, power factor, number of batteries, power consumed by the Battery Backup UPS while operating, and many other variables so you don't have to.
