1.2 Product Function

The KW600 battery tester offers several functions: battery test, cranking test, charging test, and other additional functions. The primary focus is the battery test, which analyzes the battery's healthy status to calculate its actual cold cranking capability and aging extent. This provides reliable analysis for battery testing and maintenance, potentially notifying the user to replace the battery in advance if it is aging.

The cranking test analyzes the starting motor by measuring the required cranking current and voltage to determine if the motor is functioning correctly. It helps identify issues like increased starting loaded torque or rotor friction. The charging test checks the charging system, including the generator, rectifier, and rectifier diode, to ensure the output voltage is normal. Abnormalities can lead to overcharging or incomplete charging, damaging the battery and affecting other electrical appliances.

3. Use the UP/DOWN keys to input the rated battery capacity (e.g., XX AH). For a 12V vehicle, the battery capacity is generally above 30AH.

4. Press ENTER. The testing result will be one of the following five types:

• 1 Good Battery: A gauge shows State of Health (SOH) at 70%, labeled 'GOOD BATTERY'. It also displays Resistance (R) as 14.90 mΩ, GB rating as 257A, Standard (STD) as 30A, and Voltage (VOL) as 12.88V. The battery is without any problem and can be used.
• 2 Good, Recharge: A gauge shows SOH 23%, labeled 'GOOD-RECHARGE'. It displays R: 25.97 mΩ, GB: 172A, STD: 30A, and VOL: 11.89V. The battery is good but has low current; it should be recharged before use.
• 3 Replace: A gauge shows SOH 2%, labeled 'REPLACE'. It displays R: 9.62 mΩ, CCA: 315A, STD: 2000A, and VOL: 13.47V. The battery is near or has reached the end of its lifespan and needs replacement to avoid potential danger.
• 4 Bad cell, Replace: A gauge shows SOH 0%, labeled 'BAD CELL'. It displays R: 99.99 mΩ, GB: 10A, STD: 30A, and VOL: 7.89V. The battery interior is damaged, has a bad cell, or is short-circuited and requires replacement.
• 5 Charge, Retest: A gauge shows SOH 17%, labeled 'CHARGE-RETEST'. It displays R: 30.30 mΩ, GB: 156A, and VOL: 10.90V. Unstable batteries should be recharged and retested to avoid errors. If the same test result persists after recharging and retesting, the battery is considered damaged and needs replacement.

Attention: If a "Replace" result occurs in IN-VEHICLE mode, it might be due to a poor connection between the vehicle cable and the battery. Ensure the cable is securely connected and retest the battery in OUT-OF-VEHICLE mode before making a replacement decision.

NOTE: After testing, press EXIT to directly return to the startup interface.

3.2 Battery Test in vehicle

3.3 Battery out of vehicle test

OUT-OF-VEHICLE means the battery is not connected to any vehicle load; its connection is cut off.

From the startup screen, or by pressing the EXIT button, enter the Main Menu. Press UP/DOWN keys to select the battery location (in vehicle or out of vehicle) and press ENTER to confirm.

Follow the same steps as for 'Battery Test in vehicle' for selecting Battery Type and Battery System Standard and Rating.

3.4 Waveform

From the startup screen, or by pressing the EXIT button, enter the Main Menu. Press UP/DOWN to select the [Waveform] function and press ENTER. The screen will display the waveform interface.

The waveform graph plots voltage (Unit V) against time. The Y-axis ranges from 3.0V to 18.0V. Key readings displayed are CUR (Current Voltage) 13.0, MAX (Maximum Voltage during Ignition) 13.0, and MIN (Minimum Voltage during Ignition) 8.5.

The waveform remains static until voltage changes are detected. It displays various vehicle voltage analyses.

Graph Description: The graph shows a 'Discharge Voltage' around 12V (Before Ignition), a 'Starting Voltage' drop to around 7.5-9.5V (Ignition voltage), and a 'Charging Voltage' around 14V (Alternator Charging Voltage).

Discharge Voltage: When the ignition is OFF and the engine is OFF (over 20 minutes), the discharge voltage should be around 12V. If it's lower than 11V, it will be difficult to start the ignition. If it stays under 11V, the battery is aging and needs replacement.

Starting Voltage: During ignition, the voltage drops to a minimum point (around 7.5-9.5V). If the starting voltage continuously stays under 7.5V, the battery capacity is low and needs replacement.

Charging Voltage: When the ignition and engine are ON, the alternator charges the battery, typically around 14V.

Battery Status corresponding with Battery Voltage (Before Ignition)

Battery Status corresponding with Battery Voltage (After Ignition)

Notice: If the detected battery voltage is 11.9V and remains low after a few hours, the cause could be battery damage (even with a normal alternator). Replace the battery ASAP.
