Times are based on a 50% discharged
battery and may change, depending on age
and condition of battery.
AUTOMATIC CHARGING MODE
When an Automatic Charge is performed,
the charger switches to the maintain
mode automatically after the battery is
charged.
ABORTED CHARGE
If charging cannot be completed normally,
charging will abort. When charging aborts,
the charger’s output is shut off. The
Bad Battery (red) LED will light and the
yellow/orange Charging LED will ash.
Do not continue attempting to charge this
battery. Check the battery and replace, if
necessary.
DESULFATION MODE
Desulfation could take 8 to 10 hours. If
desulfation fails, charging will abort. The
Bad Battery (red) LED will light and the
yellow/orange Charging LED will ash.
COMPLETION OF CHARGE
Charge completion is indicated by the
green Charged LED. When pulsing,
the charger has switched to the maintain
mode of operation.
MAINTAIN MODE
(FLOAT MODE MONITORING)
When the green Charged LED is
pulsing, the charger has started maintain
mode. In this mode, the charger keeps the
battery fully charged by delivering a small
current when necessary. If the charger
has to provide its maximum maintain
current for a continuous 12 hour period,
it will go into abort mode (see Aborted
Charge section). This is usually caused by
a drain on the battery or the battery could
be bad. Make sure there are no loads on
the battery. If there are, remove them. If
there are none, have the battery checked
or replaced.
MAINTAINING A BATTERY
This unit maintains both 6 and 12 volt
batteries, keeping them at full charge.
NOTE: The maintain mode technology
allows you to safely charge and maintain
a healthy battery for extended periods of
time. However, problems with the battery,
electrical problems in the vehicle, improper
connections or other unanticipated
conditions could cause excessive current
draws. As such, occasionally monitoring
your battery and the charging process is
recommended.
13. MAINTENANCE AND CARE
A minimal amount of care can keep your
battery charger working properly for years.
Clean the clamps each time you are
nished charging. Wipe off any battery
uid that may have come in contact with
the clamps, to prevent corrosion.
Occasionally cleaning the case of the
charger with a soft cloth will keep the
nish shiny and help prevent corrosion.
Coil the input and output cords neatly
when storing the charger. This will help
prevent accidental damage to the cords
and charger.
Store the charger unplugged from the AC
power outlet, in an upright position.
Store inside, in a cool, dry place. Do not
store the clamps on the handle, clipped
together, on or around metal, or clipped
to the cables.
14. TROUBLESHOOTING
PROBLEM POSSIBLE CAUSE SOLUTION
All three LEDs come on for 2
seconds, then turn off.
The charger is plugged into
an AC outlet.
No problem; this is normal.
I cannot select a 6V or 12V
setting.
The charger is equipped
with Auto Voltage Detection,
which automatically detects
the voltage and charges the
battery.
No problem; this is normal.
