Completion Of Charge
Charge completion is indicated by the CHARGED (green) LED. When lit, the charger
has stopped charging and 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. The voltage is maintained at a level determined by the BATTERY TYPE selected.
NOTE: The maintain mode technology utilized in Schumacher’s chargers allows you
to safely charge and maintain a healthy battery for extended periods of time. However,
problems with your battery, electrical problems in your vehicle, improper connections
or other unanticipated conditions could cause excessive current draws, as such,
occasionally monitoring your battery and the charging process is recommended.
Using the Battery Voltage Tester
(Models SC-1200A, SSC-1000A and SSC-1500A only)
1. With the charger unplugged from the AC outlet, connect the charger to the battery
following the instructions given in Sections 6 and 7.
2. Plug the charger AC power cord into the AC outlet, following the instructions given in
Section 8.
3. If necessary, press the BATTERY TYPE button until the correct type is indicated.
4. Read the voltage on the digital display or press the Display Mode button to set the
tester to BATTERY % to read the voltage as a percent of charge.
Tester and Charger: When first turned on, the unit operates only as a tester, not as
a charger. To continue to use it only as a tester, avoid pressing the CHARGE RATE
button. Selecting a charge rate activates the battery charger and deactivates the tester.
Power-Up Idle Time Limit: If no button is pressed within 15 minutes after the battery
charger is first powered up, the charger will automatically switch from tester to charger if a
battery is connected. In that case, the charger will be set to the start up default settings.
Tester without Time Limit: If either the DISPLAY MODE or BATTERY TYPE button is
pressed within the first 10 minutes after the battery charger is powered up, the unit will
remain a tester (not a charger) indefinitely, unless a charge rate is selected.
Testing After Charging: After the unit has been changed from tester to charger (by
selecting a charge rate), it remains a charger. To change the battery charger back to a
tester, press the CHARGE RATE switch until all charge rate LEDs are off.
12. MAINTENANCE INSTRUCTIONS
12.1 After use and before performing maintenance, unplug and disconnect the battery
charger (see sections 6, 7 and 8).
12.2 Use a dry cloth to wipe all battery corrosion and other dirt or oil from the battery clips,
cords, and the charger case.
12.3 Ensure that all of the charger components are in place and in good working condition,
including the plastic boots on the battery clips.
12.4 Servicing does not require opening the unit, as there are no user-serviceable parts.
12.5 All other servicing should be performed by qualified service personnel.
13. MOVING AND STORAGE INSTRUCTIONS
13.1 Store the charger unplugged, in an upright position. The cord will still conduct electricity
until it is unplugged from the outlet.
13.2 Store inside, in a cool, dry place (unless you’re using an on-board Marine Charger).
13.3 Do not store the clips on the handle, clipped together, on or around metal, or clipped
to cables.
13.4 If the charger is moved around the shop or transported to another location, take care to
avoid/prevent damage to the cords, clips and charger. Failure to do so could result in
personal injury or property damage.
