Feature:1. Battery Tester: The battery tester allows you to easily test and check the 12V battery, provides SOH, SOC, voltage, current, rating and many other understandable analysis data. It is compatible with 202000CCA regular flooded, AGM flat plate spiral, EFB, and GEL.2. 3 Test Function: The battery load tester will determine whether the battery is in good working condition. The crank test will determine if the electrical system has enough power to start the engine. Check the charging current, rectifier diode and generator for normal operation.3. High Accuracy: The fast and accurate results of this battery load tester will enable you to decide whether the car battery needs to be replaced. Due to the safe passive test method, the 12V battery load tester can only be powered on after being properly attached.4. Wide Application: You can test the batteries of many vehicles, including cars, motorcycles, trucks, RVs, ATVs, SUVs, boats, yachts, lawn mowers, and even club car, without needing to charge the device first.5. Easy to Use: The battery tester is easy to use because it operates through the menu system. In addition, in order to achieve reliable and safe connection during the test, the copper clip has polarity reverse prevention and spark proof features.Specification:Item Type: Car Battery TesterMaterial: ABS + MetalWorking Voltage: 8-30V DCLeakage Current Detection Range: 15mA - 5ABattery CCA Standard Range: 20 - 2000 CCACircuit Breaker Limit: 5AApplicable Model: For cars, motorbikes, trucks, RVs, ATVs, SUVs, boats, yachts, lawn mowers, and even club car4 in 1 Function:1.
