USING THE BUILT-IN BATTERY TESTER

15.

OVERVIEW: This battery charger has a built-in battery tester that displays

either an accurate battery voltage or an estimate of the battery’s relative

charge based on the battery voltage and the Battery Council International

scale.
TESTING

15.1

SEqUENCE

There are four basic steps required to use the SC-10030A as a battery

tester:

Connect the battery clamps (see sections 6 and 7).

Connect the charger power cord to a 120V AC wall outlet.

If necessary, press the Battery Type button until the correct type is

indicated.

Read the voltage on the digital display or press the digital DISPLAY

button to set the tester to Battery % and read the battery percent.

TESTER AND CHARGER

15.2

When first turned on, the SC-10030A operates only as a tester, not as a

charger. To continue to use it as only a tester, avoid pressing the BATTERY

SIZE button. Selecting a charge rate activates the battery charger and de-

activates the tester. Pressing the BATTERY SIZE button when the ENGINE

START LED is lit (except during the 180 second cool down) will shut off the

charger and activate the tester.
POWER-UP IDLE TIME LIMIT

15.3

If no button is pressed within 15 minutes after the SC-10030A is first pow-

ered up, it will automatically switch from tester to charger, if a battery is

connected. In that case, the charger will be set for the SMALL BATTERY

SIZE and 12V AGM BATTERY TYPE.
TESTER WITHOUT TIME LIMIT

15.4

If either the DIGITAL DISPLAY or BATTERY TYPE button is pressed with-

in the first 15 minutes after the SC-10030A is powered up, it will remain a

tester (not a charger) indefinitely, unless a charge rate is selected.
TESTING AFTER CHARGING

15.5

After the SC-10030A has been changed from tester to charger (by select-

ing a charge rate), it remains a charger. To change the SC-10030A back

to a tester, press the BATTERY SIZE button until all BATTERY SIZE LEDs

are all off.
TESTER STATUS LEDs

15.6

When the SC-10030A is operating as a battery tester, the status LEDs

light under the following conditions:

The CHARGED (green) LED will light if a charged battery is tested.
