What Voltage Should A Car Battery Read. Web the voltage of a car battery should be between 12.2 to 12.6 volts when the engine is turned off. Web for example, if your digital multimeter has settings for 2, 20, 200, and 2,000 volts, choose 20 since it’s the next highest number to the expected 12+ volts in a car battery.

At 25% charge, the voltage will measure around 12 volts. Web this will tell you the car’s voltage. Then, it’s a matter of attaching or touching the black lead to a ground source and probing your circuit with the red lead. Web for example, if your digital multimeter has settings for 2, 20, 200, and 2,000 volts, choose 20 since it’s the next highest number to the expected 12+ volts in a car battery. A fully charged car battery voltage falls between 13.7 and 14.7 volts with the engine running. With the engine off, you should get a reading of 12.6 volts. If the battery isn’t fully charged, it will diminish to 12.4v at 75%, 12v when it’s only operating at 25%, and down to 11.9v when it’s completely discharged. The chart above states the voltage of a car battery may be as much as 12.7 v. The best way to find out if your battery is dying is to read the voltage on your battery several times over an extended period. Watch the display for your voltage reading.
If the battery isn’t fully charged, it will diminish to 12.4v at 75%, 12v when it’s only operating at 25%, and down to 11.9v when it’s completely discharged.

Web the voltage of a car battery should be between 12.2 to 12.6 volts when the engine is turned off. However, you should keep in mind that a battery that reads low isn’t necessarily dying. It should be sitting between 12.6 and 12.8, though it. If the battery isn’t fully charged, it will diminish to 12.4v at 75%, 12v when it’s only operating at 25%, and down to 11.9v when it’s completely discharged.
