Run times in this table are approximate. Times are based on new, fully-charged, standard battery modules at a temperature of 77°F
(25°C) with 100% resistive UPS loading. Run times listed above can vary by ±5% due to manufacturing variances of the individual
batteries.
Table 9.5 Battery run times (continued)
9.1 Auto-Learning Battery Run Times
As batteries age, the estimated run times may become less accurate. The Liebert® GXT4 is programmed
to “learn” from a full battery discharge and modify the estimated run time for the measured battery
capacity. This can improve accuracy and compensate for aging batteries or batteries that operate at
different ambient temperatures.
The UPS will update the anticipated run time calculation only under certain conditions.
• The UPS must have a steady load that is greater than 20%.
• The UPS must be at 100% charge at the start of a battery discharge.
