You can use the digital voltmeter to test the battery.

Can you explain in detail how?

Sure. Connect the voltmeter to the battery. Make sure that you connect the positive terminal of the voltmeter to the positive terminal of the battery. And do the same with the negative terminal of the voltmeter. Then note the reading on the voltmeter. And this is how you take the reading of the battery. And you can do that on your own as well, but make sure that the engine and all the lights in the car are off when you do the test.
