This product is designed for use in monitoring car battery voltage, leakage current, and serving as a backup power supply when replacing the battery. The product is connected to the car's OBDII interface via an OBDII connection cable to supply 12V power to the car and monitor the car system's leakage current for diagnosing various faults. It can also serve as a backup power supply for the car during battery replacement, preventing the car's mainboard from losing power and data. Draw Monitor can also monitor battery voltage through the OBDII port. Please read the instruction manual carefully before using the product.
