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 chart below.

TESTER AND CHARGER
When first turned on, the unit operates only
as a tester, not as a charger. Selecting a
charge 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.
A minimal amount of care can keep your
battery charger working properly for years.
• Clean the clamps each time you are
finished charging. Wipe off any battery fluid
that may have come in contact with the
clamps to prevent corrosion.
• Occasionally cleaning the case of the
charger with a soft cloth will keep the finish
shiny and help prevent corrosion.

MAINTENANCE AND CARE

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 3A rate and gel cell battery type.
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 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 and turn on the vehicle's
headlights. 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.
• Coil the input and output cords neatly when
storing the charger. This will help prevent
accidental damage to the cords and charger.
• Store the charger unplugged from the AC
power outlet in an upright position.
• Store inside, in a cool, dry place. Do not
store the clamps clipped together, on or
around metal, or clipped to the cables.
