Optimizing Battery Life
by Matching the Utility Voltage
Optimize UPS battery life by using the configuration parameters to select the
best nominal voltage range for the UPS installation.
When utility voltage is outside the selected operating range, the UPS supplies
battery power to the load segments. Maximize the UPS battery life by
configuring the UPS so that the utility voltage is normally within the selected
operating range.
