OPERATING INSTRUCTIONS

The charger does not have an ON/OFF switch. The On and Off commands are
controlled by plugging the SC-8020A into a 120V AC electrical wall outlet only
after the battery connections have been made.
Charging
1. Ensure that all of the charger components are in place and in good working
condition, including the plastic boots on the battery clips.
2. Connect the battery following the precautions listed in Sections 6 and 7.
3. Connect the AC power following the precautions listed in Section 8.
4. Select the appropriate settings for your battery.
NOTE: This charger is equipped with an auto-start feature. It will not supply
current to the battery clips until a battery is properly connected. Unlike
traditional chargers, the clips will not spark if touched together.
Battery Connection Indicator
If the charger does not detect a properly connected battery, the CONNECTED
(red) LED will not light. Charging will not begin if the CONNECTED (red) LED
is not on.
Automatic Charging Mode
When the SMALL BATTERY or LARGE BATTERY size is selected, the
charger is set to perform an automatic charge. When an Automatic Charge
is performed, the charger switches to the Maintain Mode (see below)
automatically after the battery is charged.
Aborted Charge
If charging can not be completed normally, charging will abort. When charging
aborts, the charger's output is shut off and the CONNECTED (red) LED will
light. In that state, the charger ignores all buttons. To reset after an aborted
charge, either disconnect the battery or unplug the charger.
Desulfation Mode
If a 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. Activation of the special desulfation mode is indicated by the
CHARGING (yellow) LED blinking. If successful, normal charging will resume
after the battery is desulfated. The CHARGING (yellow) LED will then stop
blinking and light continuously. Desulfation could take up to 10 hours. If
desulfation fails, charging will abort and the digital display will blink.
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 battery voltage drops below a preset
level, the charger will go back into Charge Mode until the battery voltage
returns to the full charge level, at which point the charger will return to Maintain
Mode. The voltage is maintained at a level determined by the BATTERY TYPE
selected.
NOTE: For 12V AGM and 12V GEL CELL battery types, the CHARGED
(green) LED might be lit before the Maintain Mode starts.
