संकल्पना:

भार शक्ति = 150 वॅट

UPS मध्ये वापरलेल्या बॅटरीचे निर्धारित मूल्य = 12 व्होल्ट, 150 ॲम्पिअर तास

बॅटरीद्वारे पुरविण्यात आलेली ऊर्जा = व्होल्टता x ॲम्पिअर तास​

बॅटरीद्वारे पुरविण्यात आलेली ऊर्जा = 12 × 150 = 1800 ॲम्पिअर तास

∴ एक बॅटरी 1800 वॅट-तास ऊर्जा पुरवू शकते

आधार वेळ = (बॅटरीद्वारे पुरविण्यात आलेली ऊर्जा) / (भार शक्ति)

आधार वेळ \(=\frac{1800}{150}=12~h\)
