Need to determine which controllers have not had their battery tabs removed without going to each individual controller and removing its cover to perform a visual check.
During commissioning, battery tabs were not removed or batteries were not plugged into the PCB.
There is no way to see the status of the backup battery by looking at the controller object in Continuum.
One method is to create a new object in the controller (numeric), do not save to Flash, then power cycle the controller.
If the object is still in the controller after powering up (able to be opened without showing an error), then you can deduce that the battery tab has been removed and the battery is operational…if the point is not able to be viewed then the tab is still present or the battery is not holding a charge.
