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.
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.
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.
40A BOOST – For quickly adding
energy to a severely discharged or large
capacity battery prior to Engine Start.
The unit will automatically switch to
6A<>2A Charge/Maintain after the 40A
Boost operation has completed.
200A ENGINE START – Provides
200 amps for cranking an engine with a
weak or run-down battery. Always use in
combination with a battery.

BATTERY TYPE BUTTON
Use this button to select the type of battery.
– 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.
– 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. The AGM batteries
are a variant of Sealed VRLA (valve
regulated lead-acid) batteries. Popular
uses include high-performance engine
starting, power sports, deep-cycle, solar
and storage batteries.
9. Select the desired rate and battery type.
10. When disconnecting the charger,
set the switch to the OFF position,
disconnect the charger from the AC
power, remove the clamp from the
vehicle chassis, and then remove the
clamp from the battery terminal.
