1. Connect the battery following the precautions listed in Sections 6 and 7.
2. Connect the AC power following the precautions listed in Section 8.
3. Select the appropriate settings for your battery.
NOTE: Pressing any button while charging will stop the charging process and the Digital
Display will read Off.
Battery Connection Indicator
If the charger does not detect a properly connected battery, the CONNECTED (yellow)
LED will not light until such a battery is detected. Charging will not begin while the
CONNECTED (yellow) LED is not on. When charging begins, the CHARGING (yellow)
LED will illuminate.
Automatic Charging Mode
When an Automatic Charge is performed, the charger switches to the Maintain Mode (see
below) automatically after the battery is charged. NOTE: The battery must have at least a
0.1 volt charge in order for the microprocessor to analyze and begin the charging process.
Aborted Charge
If charging can not be completed normally, charging will abort. When charging aborts, the
charger’s output is shut off. The CONNECTED (yellow) LED will remain lit, and the Digital
Display will read bad bat. In that state, the charger ignores all buttons. To reset after an
aborted charge, either disconnect the battery or unplug the charger.
Desulfation Mode
If the battery is left discharged for an extended period of time, it could become sulfated
and not accept a normal charge. If the charger detects a sulfated battery, the charger will
switch to a special mode of operation designed for such batteries. Activation of the special
Desulfation Mode is indicated by the CHARGING (yellow) LED blinking. If successful,
normal charging will resume after the battery is desulfated. The CHARGING (yellow) LED
will then stop blinking and stay lit. Desulfation could take up to 10 hours. If desulfation
fails, charging will abort. The CONNECTED (yellow) LED will remain lit, and the Digital
Display will read bad bat.
Completion of Charge
Charge completion is indicated by the CHARGED (green) LED. When lit, the charger has
stopped charging and switched to the Maintain Mode of operation.
Maintain Mode
When the CHARGED (green) LED is lit, the charger has started Maintain Mode. In this
mode, the charger keeps the battery fully charged by delivering a small current when
necessary. If the battery voltage drops below a preset level the charger will go back into
Charge Mode until the battery voltage returns to the full charge level, at which point the
charger will return to Maintain Mode. The voltage is maintained at a level determined by
the BATTERY TYPE selected.
NOTE: The charger automatically switches between Charge Mode and Maintain Mode as
necessary. The CHARGED (green) LED will cycle on when the battery is at full charge and
off when the voltage drops below a preset level and the charger goes into Charge Mode.
This cycle will continue, and the CHARGED (green) LED will stay on for longer periods of
time as the battery becomes more fully charged.

Using the Engine Start feature
Your battery charger can be used to jumpstart your car if the battery is low. Follow these
instructions on how to use the ENGINE START feature.
IMPORTANT: Follow all safety instructions and precautions for charging your battery.
Wear complete eye protection and clothing protection. Charge your battery in a wellventilated area.
IMPORTANT: Using the ENGINE START feature WITHOUT a battery installed in the
vehicle could cause damage to the vehicle’s electrical system.
1. With the charger unplugged from the AC outlet, connect the charger to the battery
following the instructions given in Section 6.
2. Plug the charger AC power cord into the AC outlet.
3. With the charger plugged in and connected to the battery of the vehicle, set the Battery
Size Button to the engine start position.
4. Crank the engine until it starts or 5 seconds pass. If the engine does not start, wait 3
minutes before cranking again.
NOTE: During extremely cold weather, or if the battery is under 2 volts, charge the battery
for 5 minutes before cranking the engine.
5. If the engine fails to start, charge the battery for 5 more minutes before attempting to
crank the engine again.
6. After the engine starts, unplug the AC power cord before disconnecting the battery
clips from the vehicle.
7. Clean and store the charger in a dry location.
NOTE: If the engine does turn over, but never starts, there is not a problem with the
starting system; there is a problem somewhere else with the vehicle. STOP cranking the
engine until the other problem has been diagnosed and corrected.
Engine Starting Notes
During the starting sequence listed above, the charger is set to one of three states:
Wait for cranking – The charger waits until the engine is actually being cranked before
delivering the required amps for engine start. The charger delivers charge at a preset rate
while waiting and will reset if the engine is not cranked within 15 minutes. (If the charger
resets, it sets itself to the default start up settings). While waiting for cranking, the digital
display shows the battery voltage (it cannot be set to percent).
Cranking – When cranking is detected, the charger will automatically deliver up to its
maximum output as required by the starting system for up to 5 seconds or until the engine
cranking stops. The digital display shows a countdown of the remaining crank time in
seconds. It starts at 5 and counts down to 0.
Cool Down – After cranking, the charger enters a mandatory 3 minute (180 second) cool
down state. During this period, no settings can be changed. The buttons are ignored.
The digital display indicates the remaining cool down time in seconds. It starts at 180 and
counts down to 0. The ENGINE START LED blinks once every second. During the cool
down period, no current is delivered to the battery. After 3 minutes, the ENGINE START
LED will stop blinking and will light continuously, indicating that another crank cycle can be
started. The digital display will change from displaying the countdown back to displaying
the battery voltage. The CHARGING (yellow) LED will then be lit.
Using the Battery Voltage Tester
Overview
This battery charger has a built-in voltmeter to test your battery’s state of charge. The
charger does not have a built in load tester. As such, a recently charged battery could have
a temporarily high voltage due to what is known as “surface charge”. The voltage of such
a battery will gradually drop during the period immediately after the charging system is
disengaged. Consequently, the tester could display inconsistent values for such a battery. For
a more accurate reading, the surface charge should be removed by temporarily creating a
load on the battery, such as by turning on lights or other accessories for a couple of minutes
before you read the display. Read it a couple of minutes after you have shut the headlights off.
Testing Sequence: There are four basic steps required to test the battery state of charge:
1. With the charger unplugged from the AC outlet, connect the charger to the battery
following the instructions given in Sections 6 and 7.
2. Plug the charger AC power cord into the AC outlet, following the instructions given in
Section 8.
• 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 Display Mode button to set the
tester to BATTERY % to read the voltage as a percent of charge.
Tester and Charger: When rst turned on, the unit operates only as a tester, not as a
charger. To continue to use it only as 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.
Power-Up Idle Time Limit: If no button is pressed within 15 minutes after the battery
charger is rst 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 the start up default settings.
Tester without Time Limit: If either the DISPLAY MODE or BATTERY TYPE button is
pressed within the rst 10 minutes after the battery charger is powered up, the unit will
remain a tester (not a charger) indenitely, unless a charge rate is selected.
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 BATTERY SIZE button until all charge rate LEDs are off.
Tester Status LEDs: When the unit 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.
• The CHARGING (yellow) LED does not light in the Battery Test Mode.
• The CONNECTED (yellow) LED will light if a properly connected battery is detected.
Initial Percent Calculation: When a battery % is calculated for the rst time after
connecting a battery, the digital display will show three dashes (“---”) for a period as long
as several seconds while the tester analyzes the battery.
Using the Alternator Performance Tester
Overview
This battery charger has a built-in alternator tester that displays an estimate of the alternator’s
relative output compared to normal alternators. The alternator % values displayed should be
taken as a general reference, not a precise diagnosis. The alternator tester functions the same
as the built-in battery voltage tester (see previous section for details) with a few differences.
Testing Sequence: There are three basic steps required to operate this unit as an
alternator tester:
1. With the charger unplugged from the AC outlet, connect the charger to the battery
following the instructions given in Sections 6 and 7.
2. Plug the charger AC power cord into the AC outlet, following the instructions given in
Section 8.
3. Start the vehicle, and turn on the vehicle’s headlights. Read the voltage on the digital
display or press the DISPLAY MODE button to set the tester to ALTERNATOR % to
read the voltage as a percent of charge.
Alternator Testing Note: The DISPLAY MODE cannot be set to ALTERNATOR %
during charging.
General Charging Notes
Fan: The charger is designed to control its cooling fan for efcient 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 efciently.
Restart: If the Charge Mode is changed after charging has started (by pressing the
BATTERY SIZE or BATTERY TYPE button), the charging process will restart.
Voltage: The voltage displayed during charging is the charging voltage and is usually
higher than the battery’s resting voltage.
Charging Tips
Read this entire manual before using your battery charger. The following tips serve only as
a guide for specic situations.
• If your vehicle won’t start – It is not necessary to fully charge your battery to start
a vehicle. When the battery’s charge is 77% or more, the battery has usually been
charged enough for the vehicle to start and operate normally. If operating the vehicle
continuously for an extended period (such as a long drive), the vehicle’s charging
• 9 •
system should charge the battery back to normal during that period. If the vehicle will
only be operated for a short period (short drive), the battery might need to be charged
again before it could start the vehicle again.
• Completing an interrupted charge – Once the battery has reached 85% charge, if the
charging process is interrupted and restarted, the charger could go straight into Maintain
Mode. However, if the original charge was started using the 15◄►40A rate, the charge
can often be completed using the 2A rate.

the charger and plug it in again.
15. BEFORE RETURNING FOR REPAIRS
15.1 When a charging problem arises, make certain that the battery is capable of accepting
a normal charge. Use a good battery to double check all connections, AC outlet for a full
120-volts, charger clips for correct polarity and the quality of the connections from the
cables to the clips and from the clips to the battery system. The clips must be clean.
15.2 When a battery is very cold, partially charged or sulfated, it will not draw the full rated
amperes from the charger. It is both dangerous and damaging to a battery to force higher
amperage into it than it can effectively use in recharging.
15.3 When an UNKNOWN OPERATING PROBLEM arises, please read the complete manual
and call the customer service number for information. This will usually eliminate the need
for return.
If the above solutions do not eliminate the problem,
or for information about troubleshooting or replacement parts,
call toll-free from anywhere in the U.S.A.
