Identify the poles of your battery: there is a plus and a minus. Then, turn on your voltmeter. If it is a multimeter, switch it to voltmeter. You should choose the appropriate scale: chose a range that is above the expected voltage value. If you don't have any idea, choose the biggest range and then go down while you are measuring to get a better accuracy. Now, connect the voltmeter to the battery: you must have two wires coming out of the meter. If one is red and the other black, touch the plus pole with the red and the minus pole with the black: while you do that, the number of volts should be shown on th screen. If you invert the poles, no problem: you will get a negative value. Don't forget to change the sensibility of your meter if you chose a range of values too big for you meter (when choosing the scale). If the wires are not connected to the voltmeter, you have to do it yourself: just remember that one is minus, the other plus, and that you are using your meter as a voltmeter.

always connect voltmeter across any potential and ammeter in series of the load or supply,
