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. Set Battery Voltage to 6V or 12V.
NOTE: 24V is available only on certain models, for Boost and Engine Start.
CAUTION: Always visually confirm the voltage of the battery being charged. Not doing so can cause
damage to the battery and vehicle's electrical system. Other property damage or personal injury may occur.
6. Set Battery Type to STANDARD, AGM, or GEL. (If unsure, consult the label on the battery or the
battery manufacturer.)
7. Set Output Rate to Maintain (4A), Fast Charge (15A) or Boost.
8. Charging will start when the START/STOP button is pressed and finish automatically.
9. Charged/Maintaining (green) LED will light when finished and charger will maintain battery.
10. To stop the battery maintaining process, press the START/STOP button.
11. When charging is complete, disconnect the charger from the AC power, disconnect the negative
clamp, and finally the positive clamp.
12. A marine (boat) battery must be removed and charged on shore.

Times are based on a 50% discharged battery and may change,
depending on age and condition of battery.
DESULFATION
If the battery is left discharged for an extended period of time, it could become sulfated and not accept
a normal charge. If the charger detects a sulfated battery, the charger will switch to a special mode of
operation designed for such batteries (6V/12V only). If successful, normal charging will resume after the
battery is desulfated. Desulfation could take up to 10 hours. If desulfation fails, charging will abort and the
display will show the error message F02.
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 an error code. Do not continue attempting to charge this battery. Check
the battery and replace, if necessary.
CHARGE COMPLETION AND MAINTAIN MODE (FLOAT MODE MONITORING)
Charge completion is indicated by the green Charged/Maintaining LED. This means that the charger has
stopped charging and has switched to the Maintain Mode of operation. NOTE: 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
The charger maintains 6V and 12V 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.
