AUTOMATIC CHARGE MODE
The automatic charger uses a three-step charging process. During the BULK charge phase, the charger attempts to deliver 15 amps of
current to the battery(ies) until the battery voltage levels off. At this point, the charger enters the ABSORPTION charge phase. In this
phase, the charger will hold the battery voltage constant and let the battery determine the charging current. When the charging current
stabilizes, the charger will continue to charge for three hours to bring the battery up to full charge. The charger will then automatically
enter the MAINTAIN MODE. During this phase, the charger will hold the battery voltage constant at the appropriate level based on bat-
tery type to guard against self-discharge of the battery. The charge current will typically be a few tenths of an amp.
N.
EXTENDED BATTERY STORAGE
The charger will draw a small amount of current from the battery(ies), a few milliamps, when not charging or maintaining. If the battery(ies)
are going to be stored for an extended period of time (several months) without being charged, it is best to disconnect the leads or remove
the fuse to keep the charger from discharging the battery(ies) over time.
O.
