The MT245 Automotive Battery Tester adopts currently the world’s most advanced conductance testing technology to easily, quickly and accurately measure status of a battery under test, with functions battery test, starting system test, charging system test and others. This Battery tester can calculate the actual cold cranking capability of the battery and the extent of aging, providing reliable analysis evidence for the test and maintenance of the battery. This Automotive Battery Tester has a starting system test that is mainly to test and analyze the starting motor. Through testing the actual required cranking current and cranking voltage of the starting motor, the user can determine whether the starting motor is in perfect working order. All readings are displayed on the clear coloured LCD display, and using the Bluetooth function the meter wirelessly transmits data to the Android or iOS mobile App allowing the user to view, save, organize and share recordings. Accessories: MT245 USB Cable Instruction Manual Features: Tests all automotive cranking lead acid batteries, including ordinary lead acid battery, AGM flat plate battery, AGM spiral battery, and Gel battery, EFB battery, etc. Directly detects bad battery cells Polarity reverse connection protection, reverse connection will not damage the tester of affect the vehicle and battery Directly tests the battery with loss of electricity, no need to full charge before testing Testing standards include currently the worlds majority of battery standards, CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE, GB 2.4” TFT 240*320 pixel colour LCD display Test battery testing ranges from 100 to 2000 CCA Detects bad cells Test deep discharge battery Mini USB port for connecting directly to computer
