14.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.

14.1TESTING SEQUENCE

There are four basic steps required to use the SC-8020A as a battery tester:

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

2.Connect the charger power cord to a 120V AC wall outlet (see 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 digital DISPLAY button to set the tester to Battery % and read the battery percent. (See section 8.)

14.2TESTER AND CHARGER

When first turned on, the SC-8020A operates only as a tester, not as a char- ger. To continue to use it as only a tester, avoid pressing the BATTERY SIZE button. Selecting a charge rate activates the battery charger and deactivates 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.

14.3POWER-UP IDLE TIME LIMIT

If no button is pressed within 15 minutes after the SC-8020A 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.

14.4TESTER WITHOUT TIME LIMIT

If either the digital Display or Battery Type button is pressed within the first 15 minutes after the SC-8020A is powered up, it will remain a tester (not a charger) indefinitely, unless a charge rate is selected.

14.5TESTING AFTER CHARGING

After the SC-8020A has been changed from tester to charger (by selecting a charge rate), it remains a charger. To change the SC-8020A back to a tester, press the BATTERY SIZE button until all BATTERY SIZE LEDs are all off.

14.6TESTER STATUS LEDs

When the SC-8020A is operating as a battery tester, the status LEDs light under the following conditions:
