Using Your Battery Charger - Schumacher SC-6000A SpeedCharge Owner's Manual

while waiting and will reset if the
engine is not cranked within 10
minutes. (If the charger resets, it sets
itself for a 2A charge and REGULAR
battery.) While waiting for cranking,
the digital display shows the battery
voltage (it can't be set to percent).
2. Cranking - When cranking is
detected, the SpeedCharge will
automatically deliver up to its
maximum output (at least 60A) as
required by the starting system for up
to 8 seconds or until the engine
cranking stops. The digital display
shows a countdown of the remaining
crank time in seconds. It starts at 8
and counts down to 0.
3. Cool Down - After cranking, the unit
enters a mandatory 2-minute (120
second) cool down state. During this
period, no settings can be changed.
The buttons are ignored. The digital
OVERVIEW
Using the SpeedCharge battery charger
is very simple. First, connect the battery
and AC power following the precautions
listed under "OPERATING INSTRUC-
TIONS". Then select the appropriate
BATTERY TYPE and CHARGE RATE
for your battery. The SpeedCharge will
then do everything automatically. This
section explains a few details.
CHARGING: If the charger does not
detect a properly connected battery, the
CHECK (red) LED will light continuously
until such a battery is detected. Charg-
ing will not begin while the CHECK light
is on. When charging begins, the
CHARGING LED will be lit.
AUTOMATIC SHUT OFF: When the 2A
or 30A 10A charge rate is selected,
the charger is set to perform an auto-
matic charge. When an automatic
charge is performed, the charger stops
charging automatically after the battery
is charged.

display indicates the remaining cool
down time in seconds. It starts at 120
and counts down to 0. The 60A
START LED blinks once every
second. During the cool down period,
the charger delivers charge at a rate
of 10A and the CHARGING LED is
lit. After 2 minutes, the 60A START
LED will stop blinking and will light
continuously, indicating that another
crank cycle can be started. The
digital LED will change from display-
ing the countdown back to displaying
the battery voltage.
ENGINE STARTING NOTES:
• When the 60A START rate has been
selected, the battery type selected
does not matter and no battery type
LED will be lit.
• If the battery is disconnected during
the cool down period, the charger will
reset.
ABORTED CHARGE: If charging can't
be completed normally, charging will be
aborted. When charging is aborted, the
charger's output is shut off and the red
CHECK LED and digital LED blink on
and off (at opposite times). In that state,
the SpeedCharge ignores all buttons. To
reset from after an aborted charge,
either disconnect the battery or unplug
the charger.
DESULFATION MODE: If a battery is
left discharged for an extended period, 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 spe-
cial desulfation mode is indicated by
blinking the CHARGING LED. If suc-
cessful, normal charging will resume af-
ter the battery is desulfated. The
CHARGING LED will then stop blinking
and light continuously. Desulfation could
take up to 10 hours. If desulfation fails,
charging will be aborted and the CHECK
(red) LED will blink.
