Checking the voltage on a car battery is a simple but important task that can help you avoid getting stranded with a dead battery. A car battery’s voltage should be between 12.6 and 13.2 volts when the engine is off. If the voltage is below 12.6 volts, the battery may need to be recharged or replaced. If the voltage is above 13.2 volts, there may be a problem with the charging system.
There are a few different ways to check the voltage on a car battery. The most common method is to use a voltmeter. A voltmeter is a simple tool that can be purchased at any auto parts store. To use a voltmeter, simply connect the positive lead to the positive terminal on the battery and the negative lead to the negative terminal on the battery. The voltmeter will then display the voltage of the battery.
