Operation

Caution!! This Battery Tester becomes very hot during use. Touching it will

result in serious burns.

TESTING THE BATTERY

Note: The temperature of the battery will affect the testing data. It will test lower when

cold than when warm. Never test or charge a frozen battery.

Caution! Wear rubber gloves (not included) whenever working with the Battery

Tester or batteries.

Note: Before any testing, make sure to clean the battery contacts.

1. Make sure the vehicle is not running. Connect the Red Clamp (+) to the positive (+)

terminal post on the battery. Connect the Black Clamp (-) to the negative (-) terminal

post on the battery. Adjust the Set CCA button to correspond with the CCA of the bat-

tery. Push the CCA button (in increments of 100) until the CCA that matches your

battery appears. See FIGURE 1. Round your Battery CCA number DOWN.

2. Check the Battery Tester LED Window (See FIGURE 1) to determine effectiveness of

charge. If the Battery Tester does not register and no display is seen, double check that

the Clamps are connected to the proper terminal posts. Make certain a clean connec-

tion has been made between the Clamps and terminal posts.

3. Hold the Test Start button until a solid and consistent measurement is indicated by the

Battery Tester. A tone should sound once an acceptable reading is attained. Within ten

seconds, while continuing to hold the button, read the meter. Do not test more than

three times in a five minute period. Allow one minute for cool down between tests.

Note: Do not activate the Test Start button for more than ten seconds.

Note: If a battery does not have the charge expected, have a qualified technician check

the specific gravity. There may be an electrical drain or charging system trouble. If

charging does not raise the specific gravity, you may have a defective battery.

Operation (continued)

Analyzing test results by color display: The Battery Tester will measure battery out-

put/charge in two ways. The three lights above the LED Window (See FIGURE 1) will

indicate a color telling you the general condition of the battery.

Red = Bad, No Charge, or Completely Discharged

Yellow = Weak, Needs Recharging

Green = Good or Normal - Has Existing Charge

Analyzing test results by Voltage Reading: The LED Window will display a number

along with the color.

Green = Greater than 10.7 V - Battery is fully charged

Yellow = Between 9.0 and 10.7 V - Battery is undercharged

Red = Less Than 9.0 V - Battery is uncharged and possibly damaged

4. If the battery is without significant charge, charge it and check it again under load. The

battery should measure 75% of Open-Circuit Voltage. 75% can be considered fully

charged. If the charging rate reaches at least 75%, but fails to reach 75% during the

load test, it needs replacing. Refer to the table below for 12 Volt battery percentages:

Open Circuit Voltage (V): Less than 11.7V 12V 12.2V 12.4V 12.4V+

0% 20% 50% 75% 100%

TESTING THE CHARGING SYSTEM - Alternator / Regulator Output:

Warning: When testing a system in a car/truck, the vehicle must be on a flat, dry surface.

The transmission must be in park and the emergency brake engaged.

1. Connect the Red Clamp (+) to the positive (+) terminal post on the battery. Connect the

Black Clamp (-) to the negative (-) terminal post on the battery.

2. With the engine off, check the Battery Tester LED Window (See FIGURE 1) to deter-

mine effectiveness of charge. Without using the Test Start Button, If the Battery Tester

does not register and no display is seen, double check that the Clamps are connected

to the proper terminal posts. Make certain a clean connection has been made between

the Clamps and terminal posts.

3. Start the engine and let it run. Without using the Test Start Button, observe the volt-

age readout when the engine speed reaches between 1200 to 1500 RPM (normal idle

speed).

4. Determine battery charge based on color indicators and voltage as described above. If

the battery registers below 75 percent or the readout is not constant, you may have an

alternator/regulator problem. See a qualified service technician.

5. When charging system test is complete, remove Black Clamp (-) from battery first; then

remove Red Clamp (+).

Maintenance

1. Keep the Clamps clean and clear of dirt, grease, or debris.

2. Store and use in a dry environment away from any heat sources.

STARTER MOTOR TEST

If starting your vehicle is difficult, you may have unnecessary starter motor draw, which

dramatically shortens battery life. This test identifies starter motor performance.

1. Make sure your engine is running at normal operating temperature.

2. Connect the Red Clamp (+) to the positive (+) terminal post on the battery. Connect the

Black Clamp (-) to the negative (-) terminal post on the battery.

3. Disable the engine to make sure the car will not start. Refer to your vehicle’s service /

technical manual.

4. While watching the LED window, crank the engine briefly to determine the voltage

reading during cranking.

A display reading of 9 volts or less indicates excessive current draw. This may be

caused by a bad connection of a failing starter motor, or, the battery is too small for the

vehicle’s requirements. Consult an authorized service technician.

5. When starter motor test is complete, remove Black Clamp (-) from battery first; then

remove Red (+) clamp.
