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.
BOOST – For quickly adding energy to a severely discharged or large capacity battery prior to Engine Start.
ENGINE START – Provides additional amps for cranking an engine with a weak or run-down battery.
Always use in combination with a battery.
NOTE: Once the charger has started charging the battery; if you press the Rate Selection button once, the
output current is shut off and the display will show OFF and then the battery voltage. If you press the Rate
Selection button again, the current will go back on at the same setting it was when it was turned off.
LED INDICATORS
CLAMPS REVERSED (red) LED flashing: The connections are reversed.
CHARGING (yellow/orange) LED lit: The charger is charging/boosting the battery.
CHARGED/MAINTAINING (green) LED lit: The battery is fully charged and the charger is in maintain mode.
NOTE: See Operating Instructions for a complete description of the charger modes.
BATTERY TYPE BUTTON
Use this button to select the type of battery.
STD – 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. 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.
11. OPERATING INSTRUCTIONS
WARNING: A SPARK NEAR THE BATTERY MAY CAUSE AN EXPLOSION.
NOTE: This charger is equipped with an auto-start feature. Current will not be supplied to the battery
clamps until a battery is properly connected. The clamps will not spark if touched together (except in
Engine Start mode).
CHARGING A BATTERY IN THE VEHICLE
1. Turn off all the vehicle's accessories.
2. Keep the hood open.
3. Clean the battery terminals.
4. Place the charger on a dry, non-flammable surface.
5. Lay the AC/DC cables away from any fan blades, belts, pulleys and other moving parts.
6. Connect the battery, following the precautions listed in sections 6 and 7.
7. Connect the charger to an electrical outlet.
8. Select the battery type and desired rate.
9. When charging is complete, disconnect the charger from the AC power, remove the clamp from the
vehicle's chassis, and then remove the clamp from the battery terminal.
CHARGING A BATTERY OUTSIDE OF THE VEHICLE
1. Place battery in a well-ventilated area.
2. Clean the battery terminals.
3. Connect the battery, following the precautions listed in sections 6 and 7.
4. Connect the charger to the electrical outlet.
5. Select the battery type and desired rate.
6. When charging is complete, disconnect the charger from the AC power, disconnect the negative
clamp, and finally the positive clamp.
7. A marine (boat) battery must be removed and charged on shore.
