Other than trying to start the engine to see if there’s charge, the best way to decipher a car battery’s status is to test it using a multimeter. Digital multimeters are the best option for this since they give a more accurate reading, although you could also use an analog one.
A measuring device which can only measure the state of charge of the battery is suitable to test a conventional car battery. In an ideal case, an open circuit voltage of about 12.8 V is measured with a Multimeter. If the voltage falls below 12.4 V, the battery should be recharged as soon as possible.
When testing a start-stop battery, not only the state of charge (also known as the “SOC”), but also the state of health (“SOH”) of the battery are important. While the SOC can be simply determined with a voltage measurement, a complex test procedure is required to test the SOH, in order to make a reliable statement about the state of the battery.
However, the charge can also be measured with a voltmeter or a Multimeter. A fully charged starter battery has a voltage of 12.8 Volt. If the open-circuit voltage drops below 12.4 Volt, the battery needs to be recharged.
Interpretation of the test results for a Start-Stop battery is more difficult than with conventional starter batteries. This applies in particular to test devices with which conductivity measurement is not possible, or battery testers in which no suitable test algorithm is implemented for new battery technologies such as AGM or EFB.
Perform the following steps sequentially to check the voltage across the car battery when the car is off: Turn on the headlights for 2-3 minutes to eliminate any surface charge on the battery. Turn off the lights. Set the multimeter dial to 15-20V (DC voltage).
