Proven conductance technology and test algorithms required for warranty testing at automotive dealers around the world. Accurate battery test decision in seconds. No user interpretation required. Tests discharged batteries. Voltmeter mode for testing both the starter and the charging system. Shows available power in CCAs at the end of each test. Bad cell detection. High/low voltage capture for improved starter/charging system testing. Expanded measurement range from 100-1400 CCA. Green and red LEDs give fast decision on starter and electrical system testing.
