7. After the engine starts, press the STOP button, set the ON/OFF switch to the OFF (center) position,
unplug the AC power cord and finally disconnect the battery clamps from the vehicle, as explained in
sections 6 and 7.
8. Clean and store the charger in a dry location.
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 and the
display will show "bAd / bAt / F02".
COMPLETION OF CHARGE
Charge completion is indicated by the Charged/Maintaining (green) LED. When lit, the charger has
switched to the maintain mode of operation.
MAINTAIN MODE (FLOAT MODE MONITORING)
When the Charged/Maintaining (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 charges and maintains 6V 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.
FAN OPERATION
It is normal for the fan to be on all of the time. Keep the area near the charger clear of obstructions to
allow the fan to operate efficiently.

12. MAINTENANCE AND CARE

A minimal amount of care can keep your battery charger working properly for years.
• Clean the clamps each time you are finished charging. Wipe off any battery fluid that may have come
in contact with the clamps to prevent corrosion.
• Occasionally cleaning the case of the charger with a soft cloth will keep the finish shiny and help
prevent corrosion.
• Coil the input and output cords neatly when storing the charger. This will help prevent accidental damage
to the cords and charger.
• Store the charger unplugged from the AC power outlet in an upright position.
• Store inside, in a cool, dry place. Do not store the clamps on the handle, clipped together, on or around
metal, or clipped to the cables.
