Boost Mode
For quickly adding energy to a severely discharged or large capacity battery.
NOTE: Do not leave in Boost mode for extended periods of time. When connected for long
periods of time, Service Mode is recommended.
1. Connect the battery and AC power, following the precautions listed in sections 5, 6 and 7.
2. Set the MODE to BOOST.
3. The VOLTS LED will light, and the display will show battery voltage.
4. Press the START/STOP button. The yellow/orange
LED will light.
5. The green
LED will light and the yellow/orange
LED will turn off when the
maximum voltage is reached.
NOTE: Maximum voltage for Boost Mode is 14.4V. Disconnect the unit when maximum
voltage has been reached, to avoid overheating of the battery.
100A Flash Reprogram
NOTE: Do not attempt to Flash Reprogram a vehicle that has a discharged or defective
battery. Make sure that the vehicle battery is in good condition and fully charged before
proceeding. In Flash Reprogram Mode, the unit is able to deliver 70A charging current
continuously, and to deliver up to 100A for three minutes.
1. Press the FLASH button.
2. The VOLTS LED will light, and the display will show the default setting 14.2V.
3. Press the and buttons to adjust to the voltage needed for the vehicle being
programmed (refer to OEM specications). Selected voltage is shown on the digital
display. The unit has a voltage range of 13 to 14.8, with a default of 14.2.
4. Press the START/STOP button.
5. When nished, press the START/STOP button to exit this mode.
Using the Battery Voltage Tester
Overview
This unit has a built-in voltmeter to measure your battery’s voltage. The unit 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 seven basic steps required to test the battery state of charge:
NOTE: You cannot test the battery voltage while Flash Reprogram, Boost or Service
modes are active.
1. With the unit unplugged from the AC outlet, connect the unit to the battery, following the
instructions given in Sections 6 and 7.
2. Plug the unit's AC power cord into the AC outlet.
3. The yellow/orange
LED will light if a properly connected battery is detected.
4. Conrm the yellow/orange LED is off.
5. Set the DISPLAY to VOLTS.
6. If the output is on, press the START/STOP button. If the output is already off, do not
press the START/STOP button.
7. Read the voltage on the digital display.
General Usage Notes
Fans – The unit is designed to control its cooling fans for efcient operation. It is normal for
the fans to start and stop as needed. Keep the area near the unit clear of obstructions to allow
the fans to operate efciently. NOTE: The unit has thermal protection, and it will shut down if it
gets too hot.
Voltage – The voltage displayed during output is the loading voltage and is usually higher
than the battery’s resting voltage.
