Calculation Formula

Backup Time (Hours) = Battery Capacity (VAh) / Total Power Consumption (Watts)

Where:
Backup Time is the duration in hours that the UPS will be able to supply power.
Battery Capacity is the total energy storage capacity of the battery in Volt-Ampere hours (VAh).
Total Power Consumption is the total power draw in watts that the connected devices consume.
