13. How to Determine On-battery Run Time
Knowing the on-battery run time of the unit is an important part of use, especially in situations
where the protected device uses an operating system that requires some time to gracefully shut
down.
1.
To calculate the on-battery run time first determine the total load protected by the unit in
Volt-Amps. Obtain load figures from either the labelling on the protected equipment or the
accompanying literature. For loads specified in watts, multiply the specified figure by 1.4. For
loads specified in Amps, multiply the specified figure by 120.
2.
Add the individual loads to determine the total load.
3.
Compare the total load of your system to the run time table below.
