12.0.1Auto-Learning Battery Run Times

As batteries age, the estimated runtimes may become less accurate. The GXT2 is programmed to “learn” from a full battery discharge and modify the estimated runtime 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.

The battery discharge must continue uninterrupted until the batteries reach their end-of-dis- charge voltage.

If all conditions are not met, the run time calculation will not be modified.

If the configuration program is used to change the number of battery cabinets, then the values in the battery above table will be restored. This will override any value that is Auto-Learned.
