Battery Discharge Test, continued
Overview,

The intelligent controller provides an enhanced battery discharge test
that makes even greater accuracy possible. Enabling the
“ENHANCED” software switch utilizes the Universal Reserve Time
Prediction algorithm, which takes into account the particular discharge
characteristics of the battery subsystem. The URPT feature requires that
battery temperature be monitored and several related battery parameters
be configured. Ensure that the correct battery model is chosen for the
plant.
Note: The Battery Discharge Test feature is available with controller
software Version 6.1 for the Millennium controller.
