Ampere Hour
(Amphour, AH)
Ampere hour is a rating for batteries that specifies duration of a
discharge for a given load. It is a convention for expressing
“drain (or load) current” multiplied by time.
Battery on
Discharge (BD)
Battery on discharge occurs when the rectifier plant voltage is
below a preset threshold. Typically, the ac service voltage to the
plant is low or missing and the batteries are providing power to
the load. This condition results in a BD alarm.
Busy-Hour
Current
The average busy-hour current drain during the busy season with
the plant operating at the normal voltage

Disconnect/Recon
nect (LVD/R)
Preset voltage threshold at which the load is disconnected from
the battery
