4. Setup and Connection
Follow these steps to connect the ANCEL BT410 to a battery for testing:
- Prepare the Vehicle: Ensure the vehicle's engine is turned off and all electrical loads (lights, radio, etc.) are switched off.
- Connect Clamps: Attach the red clamp to the positive (+) terminal of the battery and the black clamp to the negative (-) terminal. Ensure a secure connection. The tester will power on automatically once connected.
- Select Battery Type: On the tester's screen, navigate to the 'Battery Test' menu. Select the correct battery type (e.g., AGM, Flooded, Lithium) and the Cold Cranking Amps (CCA) rating of your battery. This information is usually found on the battery label.

5. Operating Instructions
The BT410 offers several testing modes to diagnose your battery and vehicle's electrical system.
5.1. Battery Test
This test assesses the overall health of the battery.
- From the main menu, select Battery Test.
- Follow the on-screen prompts to input battery type and CCA rating.
- The tester will display results including Health (%), Charge (%), Internal Resistance (mΩ), and Rated CCA.
- Interpretation: The screen will indicate if the battery is 'Good', 'Good - Recharge', 'Charge & Retest', 'Replace', or 'Bad Cell'.

5.2. Cranking Test
This test evaluates the vehicle's starting system by monitoring voltage during engine cranking.
- From the main menu, select Cranking Test.
- The tester will instruct you to start the engine.
- It will monitor voltage fluctuations and cranking time.
- Interpretation: The results will indicate if the cranking system is 'Normal' or 'Abnormal', helping identify issues like a weak starter or low battery voltage during start-up.

5.3. Charging Test
This test assesses the vehicle's charging system, including the alternator.
- From the main menu, select Charging Test.
- The test involves three stages: Unloaded Test, Loaded Test (with accessories on), and Ripple Test. Follow the on-screen instructions for each stage.
- Interpretation: The tester will display voltage readings for each stage and provide a conclusion (e.g., 'Voltage Normal', 'Voltage Low', 'Voltage High') to identify potential alternator or wiring faults.
