DIGITAL DISPLAY
The Digital Display gives a
digital indication of voltage, % of
charge, time or alternator status.
The display will show the battery
Voltage when the charger is not
charging a battery. When it goes
into charging mode, the display
will automatically change to ON
(to show charging has started) and
either 6 or 12 (the voltage of the
battery, determined by the charger).
DISPLAY BUTTON
Use this button to set the function
of the digital display to one of the
following:
• Battery % – The digital display
shows an estimated charge
percentage of the battery
connected to the charger's battery
clamps, when charging.
• Alternator % (12V only) – The
digital display shows an estimated
output percentage of the vehicle's
charging system connected to the
charger's battery clamps, compared
to a properly functioning system.
The alternator percent range is
from 0% to 100%.Readings below
0% (13.2 volts) will read LO and
readings above 100% (14.6 volts)
will read HI . If you get a HI or LO
reading, have the electrical system
checked by a qualified technician.
• Voltage – The Digital Display
shows the voltage at the charger
battery clamps, in DC volts.
START/STOP BUTTON
Press to immediately begin
charging your properly connected
battery. If the button is not
pressed, charging should begin
automatically in 30 seconds.
RATE SELECTION BUTTON
Use this button to select one of the
following:
• 6<>2A CHARGE/MAINTAIN – For
charging small and large batteries.
Not recommended for industrial
applications.
• 50A BOOST – For quickly adding
energy to a severely discharged
or large capacity battery prior to
Engine Start.
• 250A ENGINE START – Provides
250 amps for cranking an engine
with a weak or run-down battery.
Always use in combination with a
battery.
LED INDICATORS
• CHARGING (yellow/orange)
LED lit: The charger is charging
the battery.
• CHARGED/MAINTAINING
(green) LED lit: The battery is
fully charged and the charger is in
maintain mode.
• CLAMPS REVERSED (red)
LED flashing: The connections
are reversed.
• CLAMPS REVERSED (red)
LED lit: The charger has detected
a problem with the battery.
See Troubleshooting for more
information.
NOTE: See Operating Instructions
section for a complete description
of the charger modes.
BATTERY TYPE BUTTON
Use this button to select the type
of battery.
• STANDARD – Used in cars, trucks
and motorcycles, these batteries
have vent caps and are often
marked "low maintenance" or
"maintenance-free". This type of
battery is designed to deliver quick
bursts of energy (such as starting
engines) and has a greater plate
count. The plates are thinner and
have somewhat different material
composition. Standard batteries
should not be used for deep-cycle
applications.
• AGM – The Absorbed Glass Mat
construction allows the electrolyte
to be suspended in close proximity
with the plate's active material.
In theory, this enhances both the
discharge and recharge efficiency.
