The following illustration graphically shows the battery discharge process at full load
conditions.

6.3 

Battery Low Voltage Tolerances 

Excessive discharge will cause the UPS system's battery voltage to drop bellow tolerable
levels. The chart shown below lists the voltage level at which each UPS unit's low-voltage
alarm will sound, and also at what level the low-voltage condition will cause the unit to
automatically shut down.
