The Christie continuous duty battery load tester, No. CT3, from Clore Automotive, uses a 250 amp fixed load to simulate actual vehicle cranking loads for accurate, reliable battery testing in a wide variety of shop and fleet maintenance environments. The tool enables assessment of 6 and 12 Volt battery state of charge, battery capacity and charging system output. The operator does not have to interpret test result numbers to determine battery condition. Instead, a large, color-coded display gives test results in simple pass/fail zones. Made in USA.
