Times are based on a 50% discharged battery and may change, depending on age and condition of battery.
ABORTED CHARGE
If charging cannot be completed normally, charging will abort. When charging aborts, the charger's output
is shut off and the Bad Battery (red) LED willl light. Do not continue attempting to charge this battery.
Have it checked or replaced.
DESULFATION MODE
While desulfation is in progress, the % and Bad Battery LEDs will be lit. Desulfation could take 8 to 10
hours. If desulfation fails, charging will abort and the Bad Battery (red) LED will remain lit.
COMPLETION OF CHARGE
Charge completion is indicated by the rightmost % LED (representing a 100% charged battery). When lit,
the charger has switched to the maintain mode of operation.
MAINTAIN MODE (FLOAT MODE MONITORING)
When the rightmost % 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.
MAINTAINING A BATTERY
This unit charges and maintains 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 ENGINE START FEATURE
Your battery charger can be used to jump start your car if the battery is low. Follow all safety instructions
and precautions for charging your battery. Wear complete eye protection and protective clothing.
WARNING: Using the Engine Start feature WITHOUT a battery installed in the vehicle could cause
damage to the vehicle's electrical system.
NOTE: If you have charged the battery and it still will not start your car, do not use the Engine Start
feature, or it could damage the vehicle's electrical system. Have the battery checked.
