Understanding Battery Test Results: What CCA, Internal Resistance, SOC, and SOH Mean Quick Summary When I test a car battery with a digital tester, I’m looking at three core things: state of charge, cranking ability (CCA), and internal resistance/conductance. A healthy battery will show strong Cold Cranking Amps (CCA), low internal resistance, and stable voltage under load. As a rule of thumb, internal resistance below 5 milliohms is excellent, 5–10 mΩ is acceptable, and anything higher usually means the battery is on borrowed time. For CCA, I expect the battery … Read More
Complete Guide to Car Battery Testing and Diagnosis
Understanding Car Battery Voltage Readings Quick Summary A proper car battery health check includes: • Measuring battery voltage • Performing a cranking test • Checking for voltage drop at the terminals, and, ideally, • Conducting a car battery CCA test with a digital battery analyzer. A battery can show 12.6 volts and still fail to start your vehicle if it can’t deliver enough current. Learning how to perform a car battery voltage test and check a car battery with a multimeter can help you avoid unexpected breakdowns and determine when … Read More
