USING THE BUILT-IN BATTERY TESTER

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.
15.1 TESTING
1. There are four basic steps required to use the SC-10030A as a battery
tester:
2. Connect the battery clamps (see sections 6 and 7).
3. Connect the charger power cord to a 120V AC wall outlet.
4. If necessary, press the Battery Type button until the correct type is
indicated.
5. Read the voltage on the digital display or press the digital DISPLAY
button to set the tester to Battery % and read the battery percent.
15.2 TESTER AND CHARGER
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

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.
15.4 TESTER WITHOUT TIME LIMIT
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.
15.5

TESTING AFTER CHARGING

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.
15.6 TESTER STATUS LEDs
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.
