AUTOMATIC CHARGING
When an Automatic Charge is performed,
the charger switches to the maintain mode
automatically after the battery is charged.
SERVICE MODE
Supplies 15A<>40A at 13.6V. The yellow/
orange CHARGING LED is lit. During
Service Mode, battery percentage is
invalid. If the display button is pressed,
the display will show battery voltage
and estimated current. Always use in
combination with a battery.
DESULFATION
If the battery is left discharged for an
extended period of time, 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,
and the display will show BAD BATTERY.
If successful, normal charging will resume

after the battery is desulfated. Desulfation
could take up to 10 hours. If desulfation
fails, charging will abort and the display
will show CHARGE ABORTED - BAD
BATTERY.
ABORTED CHARGE
If charging cannot be completed normally,
charging will abort. When charging aborts,
the charger's output is shut off, and the
display will show CHARGE ABORTED -
BAD BATTERY. Do not continue
attempting to charge this battery. Check
the battery and replace, if necessary.
CHARGE COMPLETION AND MAINTAIN
MODE (FLOAT MODE MONITORING)
Charge completion is indicated by the solid
green CHARGED/MAINTAINING LED
and the digital display showing FULLY
CHARGED - AUTO MAINTAINING.
This means that the charger has stopped
charging and has switched to the Maintain
Mode of operation. NOTE: 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
The MC118 maintains 6 and 12 volt
batteries, keeping them at full charge.
It is not recommended for industrial
applications.
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 required.
USING ENGINE START MODE
Your battery charger can be used to jump
start your car if the battery is low. Follow
all safety instructions and precautions for
charging your battery. Wear complete eye
protection and protective clothing.
WARNING: Using Engine Start mode
WITHOUT a battery installed in the
vehicle could cause damage to the
vehicle's electrical system.
NOTE: If you have charged the battery
and it still will not start your car, do
not use Engine Start mode, or it could
damage the vehicle's electrical system.
Have the battery checked.
