What Voltage Should A Car Battery Read. It should be sitting between 12.6 and 12.8, though it. 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.

Web the voltage of a car battery should be between 12.2 to 12.6 volts when the engine is turned off. Web if the car is running, the battery may display a voltage of 13.9 to 14.8 volts, because of the energy being contributed by the alternator. At 25% charge, the voltage will measure around 12 volts. Then, it’s a matter of attaching or touching the black lead to a ground source and probing your circuit with the red lead. With the engine off, you should get a reading of 12.6 volts. Web the ideal car battery voltage with the engine running is between 13.7 and 14.7v. However, you should keep in mind that a battery that reads low isn’t necessarily dying. With the battery charge at 75%, the voltage can drop to 12.4 volts. 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.
Watch the display for your voltage reading. Web this will tell you the car’s voltage. Web if the car is running, the battery may display a voltage of 13.9 to 14.8 volts, because of the energy being contributed by the alternator. 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 battery charge at 75%, the voltage can drop to 12.4 volts. Web the voltage of a car battery should be between 12.2 to 12.6 volts when the engine is turned off. Web the ideal car battery voltage with the engine running is between 13.7 and 14.7v. 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. At 25% charge, the voltage will measure around 12 volts. Then, it’s a matter of attaching or touching the black lead to a ground source and probing your circuit with the red lead.
