Features: 1.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.Specification:Item Type: Battery Tester_x005F_x000D_Material: ABS_x005F_x000D_Application: For motor vehicles, cars, motorcycles, light trucks, ATVs, SUVs, boats, yachts, mowers, and even club cars and lawn tractors._x005F_x000D_How to extend your car's battery life?_x005F_x000D_Limiting short rides and taking longer rides that allow the battery to charge fully._x005F_x000D_checking your battery terminal often and ensuring that the battery is securely fastened._x005F_x000D_Not using your electric devices like the air conditioner or the radio when your car isn't running._x005F_x000D_And of course, regular battery testing._x005F_x000D_Variety of Rating Systems: _x005F_x000D_Test results based on JIS, EN, DIN, CCA, BCI, CA, and otheres Standards.
