CHARGE RATE

The charger will automatically adjust the

charging current, based on battery size,

in order to charge the battery completely,

efciently and safely.

BATTERY CHARGING TIMES

Times are based on a 50% discharged

battery and may change, depending on age

and condition of battery.

AUTOMATIC CHARGING MODE

When the Automatic Charge is performed,

the charger switches to the maintain

mode automatically after the battery is

charged.

ABORTED CHARGE

If charging cannot be completed normally,

charging will abort. When charging aborts,

the charger’s output is shut off and the

CHARGING

(yellow/orange) LED will

ash. To reset after an aborted charge,

unplug the charger from the AC outlet,

wait a few moments and plug it back in.

DESULFATION MODE

Desulfation could take 8 to 10 hours.

If desulfation fails, charging will abort and

the CHARGING

(yellow/orange) LED

will ash.

COMPLETION OF CHARGE

Charge completion is indicated by the

CHARGED (green) LED. When

pulsing, the charger has switched to the

maintain mode of operation.

MAINTAIN MODE

(FLOAT-MODE MONITORING)

When the CHARGED (green) LED is

pulsing, 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

The SC-1200A-CA and SSC-1500A-CA

maintain both 6 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.

USING THE BATTERY VOLTAGE

TESTER

1. With the charger unplugged from the

AC outlet, connect the charger to the

battery following the instructions given

in previous sections.

2. Plug the charger AC power cord into

the AC outlet.

3. If necessary, press the BATTERY

TYPE button until the correct type is

indicated.

4. Read the voltage on the digital display.

Keep in mind that this reading is only a

battery voltage reading; a false surface

charge may mislead you. Compare the

reading to the chart below.

POWER-UP IDLE TIME LIMIT

If no button is pressed within 10 minutes

after the battery charger is rst 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 charge at the 3A rate and AGM

battery type (SC-1200A-CA) or gel cell

battery type (SSC-1500-CA).

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

CHARGING RATE button until all charge

rate LEDs are off.
