1. Introduction
The KINGBOLEN BM580 is a state-of-the-art 6V/12V automotive battery tester designed to easily, quickly, and accurately measure the actual cold cranking amps (CCA) capability of the vehicle starting battery, the healthy state of the battery itself, and common faults of the vehicle starting and charging systems. This device provides reliable analysis evidence for battery testing and maintenance, helping users identify problems quickly and accurately. It also notifies users to replace aging batteries in advance.

2. Setup and Connection
Before operating the BM580, ensure proper connection to the vehicle battery.
- Prepare the Battery: Ensure the battery terminals are clean and free from corrosion for optimal contact.
- Connect the Clamps: Connect the red alligator clamp to the positive (+) terminal of the battery and the black alligator clamp to the negative (-) terminal. The BM580 features intelligent identification of positive and negative poles and reversible access, meaning the device will function normally even if connected incorrectly, without damage to the tester or battery.


The device will power on automatically once connected. If a 'Poor Contact Prompt' appears, re-check the clamp connections to the battery terminals.
3. Operating Instructions
The KINGBOLEN BM580 offers multiple testing functions accessible via its intuitive menu. Use the navigation buttons (Up, Down, Left, Right, OK, Back) to navigate the interface.
3.1. Battery Test
This function provides an overall analysis of battery health by checking its voltage charge, internal resistance, and state of health (SOH) and state of charge (SOC).
- From the main menu, select "Check".
- Choose "In Vehicle" or "Out of Vehicle" depending on your testing scenario.
- Select "Battery Test".
- Select the appropriate battery type (e.g., Regular Flooded, AGM Flat Plate, AGM Spiral, GEL, EFB).
- Input the battery's AH (Ampere-hour) or CCA (Cold Cranking Amps) value as prompted.
- The device will display the battery's health status, including SOH, SOC, internal resistance (R), and voltage (VOL).

3.2. Cranking System Test (Startup Test)
This test analyzes the starting motor's performance by measuring the actual required cranking current and cranking voltage.
- From the main menu, select "Check".
- Choose "In Vehicle".
- Select "Startup Test".
- Follow the on-screen instructions to start the engine.
- The device will display the test result, including starting ability and voltage. If the starting voltage reading is less than 9.6V (for 12V systems) or 13.5V (for 6V systems), it indicates a potential problem with the starting system.
3.3. Charging System Test
This function checks and analyzes the vehicle's battery charging system, including the generator, rectifier, and rectifier diode.
- From the main menu, select "Check".
- Choose "In Vehicle".
- Select "Charging Test".
- Start the engine and maintain an RPM between 2500 to 3500 as instructed.
- Press the "OK" button to obtain the charging test result. The device will display loaded voltage, unloaded voltage, and ripple status.
3.4. Load Test
The load test evaluates the battery's performance under electrical load.
- From the main menu, select "Check".
- Choose "In Vehicle".
- Select "Load Test".
- Turn on various electronic devices in the car, such as car air conditioning and car audio, to create a load.
- Maintain an engine RPM between 2000 to 2500.
- The device will display the load test result, including current load, minimum voltage, and load capacity.
3.5. Voltage Waveform Monitoring
This feature allows real-time monitoring of battery voltage fluctuations.
- From the main menu, select "Waveform".
- The screen will display a live graph of voltage over time. You can monitor voltage fluctuations in real-time.

3.6. Multimeter Function
The multimeter function provides a quick overview of battery voltage and charging system status.
- From the main menu, select "Multimeter".
- The display will show battery voltage tests on the left and battery charging system tests on the right.
- A green area indicates good status, while a red area indicates a problem with the charging system.

3.7. Screenshot Function
Capture and save important test data for later review.
- During any test, long-press the "Up" and "Down" buttons simultaneously.
- The device will capture the current screen and save it. The device can store up to 10 pictures.
- To export screenshots, connect the BM580 to a computer via the Mini USB interface. The screenshots will appear as image files on the device's storage.

3.8. Record Management
The device stores test records for review.
- From the main menu, select "Records".
- You can view the last test record or delete records.
4. Maintenance
4.1. Software Updates
The BM580 supports lifetime free software updates to ensure optimal performance and compatibility with new battery technologies.
- Connect the BM580 to a computer using the Mini USB cable.
- Visit the official KINGBOLEN website to download the latest update software.
- Follow the instructions provided with the update software to complete the upgrade. No driver installation is required.

4.2. Cleaning
To maintain the device, wipe it with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
5. Troubleshooting
- Poor Contact Prompt: If this message appears, ensure the alligator clips are securely clamped to the battery's positive and negative terminals. Clean any corrosion from the terminals if necessary.
- Built-in Buzzer Reminder: If the device emits an audible reminder during a test, it indicates the battery is in poor condition and may require attention or replacement.
- Ripple Test Results: If the voltage reading is greater than 15.0V, check the voltage regulator. If the voltage reading is less than 13.3V, inspect the connection points, wires, and engine for issues.
- Startup Test Results: If the starting voltage reading is less than 9.6V (for 12V systems) or 13.5V (for 6V systems), there is a problem with the starting system.
- Device Not Powering On: Ensure the battery is not completely dead and the clamps are correctly connected.
