12V Battery Load Tester for Trucks - Digital Analyzer1、Adopt advanced conductance testing technology, easier and quicker to analyze the actual cold cranking amps capability of the vehicle starting battery, health state, starting system, and charging system common faults in milliseconds. 2、Accurately test 12 volt batteries from 100 to 1700 CCA with a wider range, including regular Flood, Gel, and Deep Cycle. Also compatible with cars, motorcycles, trucks, ATVs, SUVs, boats, yachts, mowers, and even club cars and lawn tractors. 3、Used to make sure the system works well such as the output voltage of the generator, rectifier, and rectifier diode. The starting/cranking system test enables it to display the decision of the starter system and cranking voltage to check if the starter motor works correctly. 4、Tactile “Clicky” buttons give good physical feedback of a positive push even with gloves. Automatically identify the battery types and comes straight out with test results. Designed with polarity reverse connection protection, more safer to use. 5、Simple to use and will offer you accurate readings, a handy tool to ensure your batteries are always working at an optimum level, to help you to fix the potential problems before they arise, and to replace the bad cell in time.
