6V/12V/24V Car Battery Tester KW710

User’s Manual

KW710 Battery Tester can test all 6V, 12V, 24V automotive cranking lead acid battery, including ordinary lead acid battery, AGM flat plate battery, AGM spiral battery, and Gel battery, etc. it adopts the state-of-the -art conductance testing technology in the word to easily, quickly and accurately measure the actual cold cranking amps capability of the vehicle starting battery, healthy state of the battery itself, and common fault of the vehicle starting system and charging system, which can help maintenance personnel to find the find the problem quickly and accurately, thus to achieve quick vehicle repair.

Other Feature include:

• The battery detection range is from 100 to 2000 CCA;
• Bad cell detection function;
• Polarity misconnection protection;
• Measure deeply discharged batteries;
• Various battery specifications testing (CCA, JIS, EN, DIN, SAE, IEC);
• Provide multiple language interfaces for selection: Chinese, English, German, French ,Japanese,Korean, Dutch, Russian, Spanish,Italian, Portuguese, Polish, Persian.

Noted : If test on the vehicle, please make sure to disconnect all loads, and don’t out the key in the ignition position and must close the door . Connect the red clip to the positive (+) terminal of the battery and the black clip to the negative (-) terminal. After connecting, shake the clip back and forth to make the connection firm. Before testing the battery, two clips are required to connect the terminals firmly. The best test location is the connection port of the battery. If the battery cannot be connected from the wiring port, you can try to test on the jumper port, but the measured data may be lower than the actual value.

Battery Test

1. Battery location: select inside or outside the car. During the in- vehicle test, the tester will further test the starting and charging system.

2. Important note: The performance of the starting and charging system depends on the health of the battery. It is necessary to check the starting and charging system after confirming that the battery is in good performance and fully charged.

3. Menu: select Car, Motorcycle, Truck

4. Battery type: select ordinary lead-acid battery, ordinary AGM battery, winding type AGM battery or gel battery.

5. Battery standard: Please check your own battery standard. The battery

usually uses one or more standard systems.
KW710 battery tester each battery according to the selected system and rating.
Use UP/DOWN key to select according to the actual system standard and rating marked on the battery.

1. Battery rating: up/down button to select rating, press and hold the up/down button to speed up the scrolling speed.

2. Press the Enter key to start the test. After a few seconds, the tester
   displays the result of the battery test and the measured voltage.

3. The tester can also display the type and specifications of the battery tested.

Attention: If “Replace” resulted from IN-VEHICLE mode, it might be the reason that vehicle cable is not well connected with the battery, Ensure to cut off the cable and retest the battery under OUT-OF-VEHICLE before making a decision to replace battery.

Cranking Test
Important note: Before starting the test, check the drive belt of the generator.
If the belt is shiny or worn, or lacks proper tightness, the machine will not reach the speed level required for detection.

1. When the battery test in the car is completed, the battery test results and prompts will be displayed alternately. Press Enter to test and start the system.
2. Press the enter key to do cranking system test.
3.  The tester will prompt to start the engine.
4. The KW710 tester will displays the test results : the max cranking voltage, the min the cranking voltage, and the cranking time in milliseconds, cranking lower / higher etc.

Cranking Test
TIME: 7554ms
MAX:9.84V
MIN:8.47V
CRANKING LOW

Charging Test
Once the cranking system test is completed, the screen will alternately display the cranking system test results and prompts. Press the Enter key to test the charging system. Press the Enter key to perform charging test.
Follow the instructions on the screen: Increase RPM to 2500 r/min and keep it 5 seconds, Press ENTER to continue

1. Increase the throttle when closing the load
2. The engine speed is detected and the engine is idling
3. Test the generator when the load is off and idling
4. Turn on the headlights and blower when the engine is idling
5. Test the generator when the load is clocked in and idling
6. Increase the throttle when opening the load After the process is over, the tester displays the test results of the charging system.

• Discharge Voltage: When the ignition OFF, engine OFF (Over 20 Minutes), the Discharge Voltage should be around 12V. If the discharge voltage is lower than 11V, it will be hard to turn the ignition ON. If the discharge voltage continuously stay under 11V, ii means the battery is aging and replacement is needed.
• Starting Voltage: During ignition, the voltage will drop to a certain point, at this minimum point is Starting Voltage (Around 7.5- 9.5V). If the Starting Voltage continuously stay under 7.5, it means battery capacity is low and needs to be replaced
• Charging Voltage: When the ignition ON, engine ON. The alternator will continuously charge the car battery, normally is around 14V
