USING YOUR BATTERY CHARGER
OVERVIEW
Using this battery charger is very
simple. First, connect the battery and AC
power following the precautions listed
under “OPERATING INSTRUCTIONS”.
Then select the appropriate BATTERY
TYPE and CHARGE RATE for your
battery. The charger will then do
everything automatically. This section
explains a few details.
CHARGING:
If the charger does not
detect a properly connected battery, the
CHECK (red) LED will light continuously
until such a battery is detected. Charg-
ing will not begin while the CHECK light
is on. When charging begins, the
CHARGING LED will be lit.
AUTOMATIC SHUT OFF:
When the 2A,
15A or 40A charge rate is selected, the
charger is set to perform an automatic
charge. When an automatic charge is
performed, the charger stops charging
automatically after the battery is
charged.
ABORTED CHARGE:
If charging can’t
be completed normally, charging will be
aborted. When charging is aborted, the
charger’s output is shut off and the red
CHECK LED and digital LED blink on
and off (at opposite times). In that state,
the charger ignores all buttons. To reset
from after an aborted charge, either
disconnect the battery or unplug the
charger.
DESULFATION MODE:
If a battery is left
discharged for an extended period, it
could become sulfated and not accept a
normal charge. If the charger detects a
sulfated battery, the charger will switch
to a special mode of operation designed
for such batteries. Activation of the spe-
cial desulfation mode is indicated by
blinking the CHARGING LED. If suc-
cessful, normal charging will resume
after the battery is desulfated. The
CHARGING LED will then stop blinking
and light continuously. Desulfation
could take up to 10 hours. If desulfation
fails, charging will be aborted and the
CHECK (red) LED will blink.
COMPLETION OF CHARGING:
Charge
completion is indicated by the
CHARGED (green) LED; when lit, the
charger has stopped charging and
switched to the Maintain Mode of
operation.
MAINTAIN MODE
: When the
CHARGED (green) LED is lit, the
charger has started Maintain Mode. This
mode of operation is also known as
Float-Mode Monitoring. In this mode,
the charger keeps the battery fully
charged by delivering a small current,
when necessary. The voltage is main-
tained at a level determined by the
BATTERY TYPE selected.
GENERAL CHARGING NOTES:
The unit is designed to control its
cooling fan for efficient operation.
Consequently, it is normal for the fan to
start and stop when maintaining a fully
charged battery. The fan does not run in
Tester Mode.
If the charge mode is changed after
charging has started (by pressing the
CHARGE RATE or BATTERY TYPE
button), the charging process will be
restarted.
The voltage displayed during charging is
the charging voltage and usually will be
higher than the battery’s resting voltage.
If the 6V REGULAR battery type has
been selected, and the battery voltage
exceeds 8.5 VDC, the charging process
will be aborted (see ABORTED
CHARGE above). The charger will not
charge a 12V battery if “6V REGULAR
has been selected.
