15. USING BUILT-IN BATTERY TESTER
5.

OVERVIEW

The 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 a scale set by the Battery Council International.

5.2

TESTING SEqUENCE

There are four basic steps required to use the charger as a battery tester.

. Connect the charger battery clamps to the battery.

2. Connect the charger power cord to a 20V AC outlet.

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.

5.3

TESTER AND CHARGER

When first turned on, the charger operates only as a tester, not as

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

CHARGING/STARTING button. Selecting a charge rate activates the

battery charger and deactivates the tester. Pressing the CHARGING/

STARTING button when the ENGINE START LED is lit (except during the

80 second cool down) will shut off the charger and activate the tester.

5.4

POWER-UP IDLE TIME LIMIT

If no button is pressed within 15 minutes after the unit is first powered up,

it will automatically switch from tester to charger, if a battery is connected.

In that case, the charger will be set for the 2A SMALL BATTERY charge

rate and 2V STANDARD battery type.

5.5

TESTER WITHOUT TIME LIMIT

If either the DIGITAL DISPLAY or BATTERY TYPE button is pressed

within the first 15 minutes after the unit is powered up, it will remain a

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

5.6

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 unit back to a tester, press

the CHARGING/STARTING button until all charge rate LEDs are off.
