How to measure battery capacity with a multimeter?

Set the dial to measure voltage. Choose a voltage range higher than the voltage you are expecting to measure. If you are unsure about this, it is a first class idea to start at the highest voltage setting [1] and later step down until you get a first class resolution nnect the black probe to the COM terminal and connect the red probe to the red terminal with a "V" in its

Testing Batteries With a Multimeter

To measure the voltage, we simply need to select the DC function on our multimeter, and then we connect the red lead to the positive terminal and the black lead to the negative. This will give us a voltage reading. You can see that this battery is rated at 1.5 volts, but when we test it, we get 1.593 volts. The two values are close, but usually

4 Ways to Test Your Batteries

Take an exact voltage reading with a multimeter, voltmeter, or battery tester to get an exact charge reading. You can also use a multimeter or voltmeter to test your car battery. Finally, test your cell phone battery by using
