12. OPERATING INSTRUCTIONS
Charging the battery
An important fact to keep in mind when charging a battery
is that, the more a battery is discharged, the faster it
absorbs charge from the charger. In other words, it takes
longer for the battery to absorb the last few percents of
charge than the rst several percents.
WARNING: When the START button is pressed in either
Boost mode, Maintain/Charge mode or Engine Start mode,
the clamps are energized and will spark if touched together.
A spark near the battery may cause an explosion.
NOTE: A marine (boat) battery must be removed and
charged on shore.
Boost or Maintain/Charge Mode
1. Set the ON/OFF switch to the OFF center position.
2. Connect the charger to the battery and AC power as
explained in sections 6 and 7.
3. With the charger plugged in and connected to the
battery of the vehicle, set the ON/OFF switch UP to the
Boost or Maintain/Charge position. The display will
show the current voltage of battery.
4. BOOST mode will be selected by default. In case the
yellow/orange 40A LED does not light, press the RATE
SELECTION button until the 40A LED lights solid. To start
boosting the battery in this mode, just press the START
button. The yellow/orange Boost/Charge LED will light
solid if battery is properly connected, and the boosting
process will start. The display will show the Voltage of the
battery. To change the mode of display to Amperes, press
the Display switch. If a bad battery is detected, the yellow/
orange Boost/Charge LED will ash.
NOTE: Boost mode will remain energized until the STOP
button is pressed or the main ON/OFF switch is set to
OFF position.
5. MAINTAIN/CHARGE mode: to select this mode, press
the RATE SELECTION button until the yellow/orange
2A-6A LED lights and then press the START button.
The yellow/orange Boost/Charge LED will light solid if
battery is properly connected and the charging process
will start. The display will show the Voltage of the battery.
To change the mode of display to Amperes, press the
Display switch. When the battery is fully charged, the
green Maintaining/Charged LED will pulse. If charging
cannot be completed, the yellow/orange Boost/Charge
LED will ash. The battery may be bad; have it checked.
NOTE: If voltage of battery is under 12.7V, charger will
automatically go into BOOST mode to quickly add energy
to the battery. To abort/skip the temporary Boost, and
force the charger into the Maintain/Charge mode, press
the RATE SELECTION button again (while still boosting).
NOTE: When the charger is in Maintain/Charge mode, the
display will automatically go into sleep mode (auto shut
off) after 2 minutes. To turn the display back on, press any
of the push-buttons. The display won’t auto shut off again.
To manually turn off the display on this mode, press the
display button until the display turns off.
6. To stop the charging process, press the STOP button,
set the ON/OFF switch to the (OFF) center position
and disconnect the charger from the AC outlet and
battery as explained in sections 6 and 7.
Using the Engine Start Feature
Your battery charger can be used to jumpstart your car if
the battery is low.
IMPORTANT: Follow the same safety instructions and
precautions as when charging the battery. Wear complete
eye protection and clothing protection. Charge your
battery in a well-ventilated area.
WARNING: Using the ENGINE START feature
WITHOUT a battery installed in the vehicle could cause
damage to the vehicle’s electrical system.
NOTE: If the engine turns over, but never starts, there
is not a problem with the battery or the starting system;
there is a problem somewhere else in your vehicle. STOP
cranking the engine until the other problem has been
diagnosed and resolved.
NOTE: During extremely cold weather, or if the battery is un-
der two volts, rst boost the battery in 40A Boost mode for at
least several minutes before using the Engine Start feature.
NOTE: If you have already charged the battery and
it still does not start your car, do not use the ENGINE
START feature, as it could cause damage to the vehicle’s
electrical system. Have the battery checked.
1. Set the ON/OFF switch to the OFF center position.
2. Connect the charger to the battery and AC power, as
explained in sections 6 and 7.
3. With the charger plugged in and connected to the
battery of the vehicle, set the ON/OFF switch DOWN
to the Engine Start position. If the battery is properly
