Attach the accessory harness to the battery noting the correct polarity. In some
applications, this will be a short cable with ring terminals and an insulated polarized
connector and may be permanently mounted to the battery. Connect the output cable to
the battery harness. Hooking up the cables in this order will contain any possible spark
within the insulated connector – not at the battery terminals. The output connector must
be attached to the battery for 1 second, continuously, before the battery is detected and
the charger turns on the output, lights the charge indicator, and begins charging the
battery. If the battery voltage is too high or too low, the charger will assume that an
incorrect voltage battery was installed and will display a fault. If the battery is attached in
a reverse condition, the charger will not be damaged but it will not detect the battery and
will not turn on.
Condition Charge Stage
Charging begins with a light conditioning charge, about 10% of the maximum charge
current, until the battery reaches 10.5 volts. This qualifies the battery by ensuring that it is
in proper condition to accept the full rated charge current before entering bulk charge.
Bulk Charge Stage
During bulk charge, the full rated current is delivered to the battery until the voltage rises
above 12 volts, at which point the current will drop slightly to maintain a constant 150
watts of charging power. Approximately 80% of the battery capacity is returned during
the bulk charge. The bulk charge ends when the charge voltage climbs to the absorption
voltage and the battery begins to draw less current.
Absorption Charge Stage
During the absorption charge, the charge voltage is regulated at a constant high rate and
the current drawn by the battery decreases as the battery becomes more charged. The
charge indicator will begin to flash upon entering the absorption charge mode. The time
spent during the absorption charge is proportional to the time spent during the bulk mode,
based on 3 times the time spent in bulk (1.5 times in heavy-cycle mode), and has a
minimum timer of 1 hour and a maximum timer of 8 hours (6 hours in heavy-cyclic
mode). After 1 hour, the absorption charge will also end when a minimum charge current
is detected. When the absorption charge ends the battery should be over 100% recharged.
A small overcharge is required to prevent chronic undercharging – a leading cause of
battery failure. At this point the charger will enter the float charge mode and the charge
indicator will darken and the ready indicator will light.
Equalize Charge Stage (heavy-cyclic mode only)
If the heavy-cyclic charge program is selected, the absorption charge will be shortened by
half and it will be supplemented with a constant current equalize charge lasting for 0.5 of
the time spent in bulk, or 1 hour max. The charge current is limited to 10% of the
maximum charge current. This charge program may not be appropriate for all battery
types and capacities. Consult your battery documentation.
