Introduction
The KAIWEETS KVB01 Car Battery Tester is a versatile diagnostic tool designed to assess the health and performance of 12V and 24V lead-acid batteries. It provides comprehensive analysis including State of Charge (SOC), State of Health (SOH), voltage, internal resistance, and performs loading, cranking, and charging tests.
This tester is compatible with various battery types, including ordinary flooded, VRLA, GEL, AGM, SLA, and SLI batteries. It is suitable for use with almost all automotive batteries found in SUVs, motorcycles, trucks, boats, golf carts, and lawnmowers.

Operating Instructions
The KVB01 features a clear and concise navigation interface, making it user-friendly even for first-time users. Use the arrow buttons to navigate and the 'M ENTER' button to select options.
1. Battery Test
This test measures the voltage, internal resistance, State of Charge (SOC), and State of Health (SOH) of the car battery. It helps you know the status of your battery in advance before it dies.
- Connect the tester to the battery terminals.
- From the Main Menu, select "BATTERY TEST".
- Choose the appropriate battery type (e.g., Flooded, VRLA, GEL, AGM, SLA, SLI) and standard (e.g., CCA, IEC, EN).
- The tester will display the battery's condition, including SOC, SOH, VOLTS, CCA, and RES (internal resistance).
- The tester will provide suggestions based on the measurement results (e.g., "GOOD", "ATTENTION", "REPLACE", "PLEASE CHARGE").
2. Cranking Test
This test analyzes the battery discharge performance by measuring the actual cranking voltage. It helps determine if the battery can provide sufficient power to start the engine.
- Connect the tester to the battery.
- From the Main Menu, select "CRANKING TEST".
- Follow the on-screen prompts to start the vehicle's engine.
- The tester will display the dynamic voltage, cranking voltage, and compare it to the standard.

3. Loading Test
This test analyzes the generator performance under load. It helps ensure your vehicle's charging system can maintain proper voltage when accessories are active.
- Connect the tester to the battery.
- From the Main Menu, select "LOADING TEST".
- Turn on vehicle loads (e.g., headlights, AC, radio) and increase engine speed to 2000-2500 RPM as prompted.
- The tester will display dynamic voltage, minimum voltage, and compare it to the standard.
4. Charging Test
This test analyzes the running status of the automobile charging system, including the alternator and voltage regulator.
- Connect the tester to the battery.
- From the Main Menu, select "CHARGING TEST".
- Follow the on-screen prompts to start the engine and maintain specific RPMs.
- The tester will display dynamic voltage, maximum voltage, and minimum voltage, providing an assessment of the charging system's health.
Maintenance
- Keep the tester clean and dry. Wipe with a soft, damp cloth if necessary.
- Store the tester in its provided carrying case when not in use to protect it from dust and damage.
- Ensure the copper clips are clean and free of corrosion for accurate readings.
- Avoid exposing the tester to extreme temperatures or direct sunlight for prolonged periods.
Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| "ATTENTION" or "REPLACE" message during Battery Test | Low State of Charge (SOC) or poor State of Health (SOH). | Charge the battery fully and retest. If the issue persists, the battery may need replacement. |
| No display or power | Incorrect connection to battery terminals or battery is completely dead. | Ensure correct polarity (+ to + and - to -). Try connecting to a known good battery. |
| Inaccurate readings | Corroded battery terminals or loose connections. | Clean battery terminals and ensure a firm connection of the copper clips. |
| Tester not responding | Temporary software glitch. | Disconnect from the battery, wait a few seconds, and reconnect. |
