Load Power = 150 watts
Rating of battery used in UPS = 12 Volts, 150 Ah
The energy supplied by battery = Voltage x Ah
Energy supplied by battery = 12 × 150 = 1800 watt-hour
∴ A battery can supply energy of 1800 watt-hour
Backup time = (Energy supplied by the battery)/(Load Power)
Backup time \(=\frac{1800}{150}=12~h\)
