- Enter the battery's Cold Cranking Amps (CCA) rating as prompted.
- Press 'OK' to start the test. The results (Voltage, SOC, SOH, Resistance, Temperature) will be displayed.
6.2. V/A Monitor (Voltage/Current Monitor)
This function allows real-time monitoring of voltage and current waveforms.
- From the main menu, select "V/A Monitor".
- Choose either "Voltage" or "Current" to view the respective waveform.
Refer to Video 5.1 (0:16 - 0:26) for a demonstration of the V/A Monitor function.
6.3. Cranking Test
The Cranking Test evaluates the battery's ability to start the engine.
- From the main menu, select "Cranking Test".
- Follow the on-screen instructions: "Turn off the engine, if necessary, turn on the lights for 2 minutes, discharge, and then test again. Press OK to next."
- When prompted, start the engine.
- The tester will display the cranking voltage and status (e.g., Normal).
Refer to Video 5.1 (0:27 - 0:33) for a demonstration of the Cranking Test procedure.
6.4. Charging Test
This test checks the vehicle's charging system (alternator).
- From the main menu, select "Charging Test".
- Follow the on-screen instructions: "Start the engine and keep idling, press OK to continue, ESC to exit."

- Follow the on-screen instructions: "Please turn on all electric devices. Start the engine, wait 15 seconds. Press OK to start testing."
- The tester will display the maximum load testing voltage, current voltage, and minimum voltage, indicating the battery's capacity under load.
Refer to Video 5.1 (0:40 - 0:48) for a demonstration of the Load Test procedure.
6.6. Data Review & Printing
The BT880 allows you to review previously recorded test data and print results.
- From the main menu, select "Review".
- You can choose to "Record data" or "Delete Record data". Select "Record data" to view a list of past tests.
- To print a selected test result, navigate to the desired record and press the dedicated print button on the device.
Refer to Video 5.1 (0:49 - 0:59) for a demonstration of data review and printing.
6.7. Language Settings
The device supports 18 languages.
