Step-by-Step Guide: Testing Your Car Battery with a Voltmeter

Testing a car battery with a voltmeter is a simple but effective way to ensure that your battery is functioning properly. A voltmeter measures the electrical potential difference between two points in a circuit, and in the case of a car battery, it can be used to measure the voltage of the battery terminals.

A healthy car battery should have a voltage of around 12.6 volts when it is fully charged. When the engine is running, the voltage should be between 13.5 and 14.5 volts. If the voltage is below 12.6 volts, it means that the battery is not fully charged and may need to be replaced. If the voltage is above 14.5 volts, it means that the battery is overcharging and may be damaged.
