ANCEL BA201 car battery tester adopts the state-of-the-art conductance testing technology to measure the actual cold cranking amps capability of starting battery, battery healthy state, and common fault of starting system and charging system quickly and accurately. It works on 12V lead-acid batteries, such as regular flooded, AGM flat plate, AGM spiral, GEL, and EFB battery for vehicles, SUV, motorcycle, light truck, boat, and more. Based on the majority of battery standards, such as CCA, BCI, CA, MCA, JIS, DIN, SAE, etc., you get the accurate test results in merely seconds, including battery state, state of health(SOH), state of charge(SOC), internal resistance(mΩ), standard CCA, rating CCA, and voltage value.
