Battery Replacement with ECU Memory Saved

Replace your vehicle battery without losing ECU memory data. The process is straightforward:

1. Prepare an extra spare vehicle battery. Connect the device to the spare battery correctly with red clip to positive pole and black clip to negative pole.
2. Plug the OBD2 adapter to the Data Link Connector socket in the vehicle. Press OK to proceed.
3. The vehicle battery can now be safely replaced while ECU memory is preserved.

OBD Voltage Detection

Select the "OBD-PIN" function and press OK to view the voltage value of each pin of the OBD2 connector. Displays voltage readings for pins 2, 6, 7, 10, 14, 15, and 16, helping diagnose communication issues quickly.

Electric Leakage Detection

Select the "Current" function to detect electric current leakage. Features include current measurement display, waveform review, and result deletion. Records current data and waveform for up to 30 minutes. Detection range: 15mA to 5A.

Battery Analyzer

Select the "BAT Test" function to perform comprehensive battery analysis with multiple test standards. The battery test screen displays: battery status, voltage, CCA value, electricity percentage, Battery Life (SOH%), and resistance (mOhm). Supports CCA standards range: 20 to 2000 CCA.

Software Upgrade

Supports software updates via PC connection, ensuring the tool stays current with the latest features and improvements.

Multi-Language Support

Interface available in 10 languages: English, Spanish, German, French, Italian, Portuguese, Polish, Chinese, Japanese, Korean.
