Battery health test: Applied with the latest testing algorithm, the tester scan the battery and get the results in seconds, including the State of Health, the State of Charge, the Internal Resistance and the Testing Conclusion (Poor, Good, Great) Fast and accurate detection: Thanks to the high-quality integrated chip, the test result accuracy rate of the battery health tester reaches 99.5%. At the same time, it adopts advanced conductivity test technology, which can be displayed on the LCD screen in only 3 seconds to view accurate battery health data Simple operation: Just connect the smart clip of the on-board digital battery tester to the car battery correctly, you can check the , SOC, power, internal resistance, and discharge capacity of the battery at the same time. Overvoltage/Reverse Polarity Protection: Through the low frequency signal test, the vehicle battery tester protects the battery during the test. Premium copper clips are reverse polarity protected and spark for a stable and secure connection during testing Must-Have Battery Assistant: As a car battery analyzer with a dot matrix LCD display, diagnose battery health issues anytime, anywhere.
