11. OPERATING INSTRUCTIONS

WARNING: A SPARK NEAR THE BATTERY MAY CAUSE AN EXPLOSION.
IMPORTANT: Do not start the vehicle with the charger connected to the AC outlet, or it could result in damage to the charger.
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.
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 charging 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 charging 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.
CHARGE RATE
The charger will automatically adjust the charging current, based on battery size, in order to charge the battery completely, efficiently and safely.
BATTERY CHARGING TIMES
Times are based on a 50% discharged battery and may change, depending on age and condition of battery.
AUTOMATIC CHARGING MODE
When the Automatic Charge is performed, the charger switches to the maintain mode automatically after the battery is charged.
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 "bad / bat" and an error code.
Do not continue attempting to charge this battery. Have it checked or replaced.
DESULFATION MODE
The display will show "SUL" when a sulfated battery is detected, and the charger will go into desulfation mode. If the desulfation is not successful after 10 hours, the charger will
go into abort mode. The display will show "bAd / bAt / F02".
COMPLETION OF CHARGE
Charge completion is indicated by the Charged (green) LED. When lit, the charger has switched to the maintain mode of operation.
MAINTAIN MODE (FLOAT-MODE MONITORING)
When the Charged (green) LED is lit, the charger has started maintain mode. In this mode, the charger keeps the battery fully charged by delivering a small current when necessary.
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
This unit maintains both 6 and 12 volt batteries, keeping them at full charge.
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 THE BATTERY VOLTAGE TESTER
1. With the charger unplugged from the AC outlet, connect the charger to the battery following the instructions given in previous sections.
2. Plug the charger AC power cord into the AC outlet.
3. If necessary, press the BATTERY TYPE button until the correct type is indicated.
4. Read the voltage on the digital display. Keep in mind that this reading is only a battery voltage reading; a false surface charge may mislead you. Compare the reading
to the chart below.
6V Battery Voltage Reading 12V Battery Voltage Reading Battery Condition
6.4 or more 12.8 or more Charged
6.1 to 6.3 12.2 to 12.7 Needs charging
Less than 6.1 Less than 12.2 Discharged
