NOTE: If you have charged the battery and it still will not start your car, do not use the Engine Start
feature, or it could damage the vehicle’s electrical system. Have the battery checked.
1. With the charger unplugged from the AC outlet, connect the charger to the battery following the
instructions given in Follow These Steps When Battery is Installed in Vehicle.
2. Connect the charger to a live grounded 120V AC outlet.
3. With the charger plugged in and connected to the battery and chassis, press the Rate Selection button
until the Engine Start LED is lit, and then press the START button.
4. Crank the engine until it starts or 7 seconds pass. If the engine does not start, repeat. Do not crank
during the cool down period (see below). This allows the charger and battery to cool down. 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 clamps 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 four states:
• Wait for ready – The charger charges the battery for 2 minutes before the Wait for Cranking state. While
waiting for ready, the digital display shows
On
and the engine can be cranked. For severely discharged
batteries, it is not recommended to crank during this time.
• Wait for cranking – The charger waits until the engine is actually being cranked before delivering the amps
for engine start. While waiting for cranking, the digital display shows
rdy
.
• Cranking – When cranking is detected, the charger will automatically deliver up to its maximum output as
required by the starting system for up to 7 seconds.
• Cool Down – After repeated cranking during a 3-minute ready period, the charger enters a mandatory
3 minute (180 second) cool down state. The digital display indicates the remaining cool down time in
seconds. It starts at 180 and counts down to 0. After 3 minutes, the digital display will change from
displaying the countdown to displaying
rdy
. After 2 hours of Engine Starting, the unit will automatically
reset to Tester mode, just as if the STOP button had been pressed.
TESTER AND CHARGER MODES
When first powered up, the unit operates only as a TESTER, not as a charger. Pressing the START/STOP
button deactivates the tester mode and activates the CHARGER mode. Pressing the START/STOP button
again will shut off the charger mode and activate the TESTER mode.
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 sections 6 and 7.
2. Connect the charger to a live grounded 120V AC outlet.
3. If necessary, press the Battery Type button until the correct battery 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.

NOTE: The battery tester is only designed to test batteries. Testing a device with a rapidly changing
voltage could yield unexpected or inaccurate results.
