UPS battery calculation with operating time

Calculation method for UPS backup time:

(Single battery capacity x number of batteries x 12V battery voltage)/device power x 0.7 loss=extendable time (hours)

Example: G1KL is equipped with 3 100AH batteries for 600W devices, with a capacity of (100AH × 3 × 12V)/600W × 0.7=4.2H (hours)
