Features: The latest battery tester, the latest classic backlight tester upgrade, is designed to quickly and accurately check the health of the battery and check the operating status of the alternator. It is a professional vehicle diagnostic tool that checks your battery system problems with a graphical voltage monitoring tool with colored screen and unique pattern design. Use STM32 chipset hardware for fast and smooth operation. Identify that the battery is in good condition or need to be replaced. Check battery capacity - Cold start current (CCA), DIN, EN and IEC related battery ratings. Check the internal resistance value (m)and show life in percentage (%). Battery start test, load test battery charge test, ripple test,graphic voltage real-time monitoring,test results are stored and reviewed. Print test results and battery reports on your PC.
