5. Operating Instructions
The BD10 tester features an easy-to-use interface. Use the Up/Down arrow buttons to navigate through menu options, the 'MEAS ENTER' button to select or confirm, and the 'BACK' button to return to the previous screen.
5.1. Battery Test (Measurement of Battery Life)
This test measures the battery's State of Health (SOH), State of Charge (SOC), Voltage, Internal Resistance, and Cold Cranking Amperes (CCA).
| Test Result | Condition |
|---|---|
| Replace | SOH < 45% |
| Attention | SOH ≥ 45% |
| Normal | SOH ≥ 60% |
| Good | SOH ≥ 80% |
| Please Charge | 12V Battery: Voltage < 12.3V 24V Battery: Voltage < 25.6V |
Note: UPS batteries and motorcycle batteries can only measure internal resistance, power, and voltage, not battery life. If the voltage is less than 12.0V (for a 12V battery) or 24.0V (for a 24V system), the measurement result is invalid, and retesting after charging is required.
5.2. Cranking Test (Measurement of Battery Discharge Performance)
This test evaluates the battery's ability to deliver current during engine cranking.
| Test Result | Cranking Voltage Value |
|---|---|
| Good | Above 10.2V |
| Normal | 9.6V - 10.2V |
| Attention | Less than 9.6V |
5.3. Charging Test (Generator Charging System Test)
This test assesses the performance of the vehicle's charging system.
| Test Result | Voltage Value |
|---|---|
| Good | 12V Battery: Min voltage > 13.3V & Max voltage < 15.0V 24V Battery: Min voltage > 26.6V & Max voltage < 30.0V |
| Attention | 12V Battery: Min voltage < 13.3V & Max voltage > 15.0V 24V Battery: Min voltage < 26.6V & Max voltage > 30.0V |
5.4. Loading Test (Measurement of Generator Performance)
This test measures the performance of the vehicle's generator under load.
| Test Result | Voltage Value |
|---|---|
| Good | 12V Battery: Min voltage > 13.4V 24V Battery: Min voltage > 26.8V |
| Normal | 12V Battery: Min voltage > 12.8V 24V Battery: Min voltage > 25.6V |
| Attention | 12V Battery: Min voltage < 12.8V 24V Battery: Min voltage < 25.6V If any of these measurements occur, check whether the generator belt is worn out, and whether the wire is short-circuited. |
6. User Tips
- Always ensure battery terminals are clean and free of corrosion for the most accurate readings.
- For optimal results, especially when checking State of Health (SOH), perform tests on a fully charged battery.
- If the battery voltage is too low for a valid test (e.g., below 12.0V for a 12V battery), charge the battery before retesting.
- The BD10 uses a non-damaging Kelvin test method, making it safe for repeated use on your battery.
7. Troubleshooting
- No Display/Device Not Powering On:
- Check that the test clamps are securely connected to the correct battery terminals (red to positive, black to negative).
- Ensure the battery has sufficient charge to power the device. If the battery is completely dead, the tester may not turn on.
- 'Bad Contact Reminder' Message:
- The clamps are not making good electrical contact with the battery terminals. Re-attach the clamps firmly, ensuring they grip the metal terminals directly, not just corrosion or plastic.
- Clean any corrosion from the battery terminals.
- Invalid Test Result (Low Voltage):
- If the battery voltage is below 12.0V for a 12V battery or 24.0V for a 24V system, the test results for battery life may be invalid. Charge the battery fully and retest.
- 'Attention' Result in Charging Test or Loading Test:
- This indicates a potential issue with the vehicle's generator or charging system. Check the generator belt for wear and tear, and inspect wiring for any short circuits. Professional inspection may be required.
8. Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the BD10 tester in its protective carrying case when not in use. Keep it in a cool, dry place, away from direct sunlight and extreme temperatures.
- Test Leads: Regularly inspect the test leads and clamps for any signs of damage, fraying, or corrosion. Replace if necessary to ensure safe and accurate operation.
- Battery (Internal): The device is powered by the vehicle battery being tested and does not contain an internal rechargeable battery requiring maintenance.
9. Warranty and Support
The Hanmatek BD10 Battery Tester is covered by the manufacturer's standard warranty. For warranty claims, technical support, or service inquiries, please refer to the contact information provided with your purchase or visit the official HANMATEK website.
