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 following chart.
6V Battery
Voltage
Reading
6.4 or more 12.8 or more
6.1 to 6.3
Less than
6.1
TESTER AND CHARGER
When first turned on, the unit operates
only as a tester, not as a charger. Selecting
a rate activates the battery charger and
deactivates the tester. Pressing the RATE
SELECTION 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 10 minutes
after the battery charger is first 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 6<>2A rate and Gel battery type.

TESTING AFTER CHARGING
After the unit has been changed from tester
to charger (by selecting a rate), it remains a
charger. To change the battery charger back
to a tester, press the RATE SELECTION
button until all charge rate LEDs are off.
NOTE: The battery tester is only designed
to test batteries. Testing a device with
a rapidly changing voltage could yield
unexpected or inaccurate results.
USING THE ALTERNATOR
PERFORMANCE 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. Start the vehicle, rev the engine at
2000 rpm for 30 seconds and turn
on the vehicle's headlights or other
accessories.
4. Read the voltage on the digital display.
If you get a reading between 13.4
volts and 14.6 volts, the alternator
is working properly. If the reading
is less than 13.4 volts or more than
14.6 volts, have the charging system
checked by a qualified technician.
NOTE: Refer to your vehicle owner's
manual for appropriate voltage numbers
for your alternator.
FAN OPERATION
It is normal for the fan to start and stop
when maintaining a fully charged battery.
The fan does not run in Tester Mode.
Keep the area near the charger clear of
obstructions, to allow the fan to operate
efficiently.
RESTART
If the Charge Mode is changed after
charging has started (by pressing the
RATE SELECTION or BATTERY TYPE
button), the charging process will restart.
CHARGING 6V – XX% (Yellow/orange
CHARGING LED lit) – Plugged into the
AC outlet and correctly connected to a
discharged 6V battery.
CHARGING 12V – XX% (Yellow/orange
CHARGING LED lit) – Plugged into the
AC outlet and correctly connected to a
discharged 12V battery.
FULLY CHARGED AUTO MAINTAINING
(Green CHARGED/MAINTAINING LED
solid) – Plugged into the AC outlet and
correctly connected to a fully charged 6 or
