![]() If you set this correctly, the display of the multimeter will show the voltage in a positive number (e.g. Then connect the black probe of the multimeter to the negative terminal of the battery and the red probe to the positive terminal of the battery.If the range is less than the voltage of the battery, the meter will display ‘1’. This is an optimum range for measuring batteries within 20V. First, the range of the multimeter should be set at 20V on the DC side.Follow these steps below to test a battery with a multimeter: But you must use precaution in case of using AC, it is not an easy mechanism to measure that. Measuring DC with a digital voltmeter is safe. Usually, all portable devices supply DC (Direct current). With a multimeter, you can check the potential difference of a battery which will tell you whether the battery is good or not. Because Analog multimeters are not suitable for measuring the voltage of batteries. Among the two, digital multimeters are the best to measure values such as battery load tests. The multimeter battery test function allows you to measure a battery’s potential. The digital one comes with a digital display and precision knob to control the type of electricity you want to measure under the range (of any of the values a multimeter can measure). Multimeters can be two types: 1) Digital, 2) Analog.Īnalog is the one that comes with a scale with a needle pointer. Which Type of Multimeter Do You Need To Test A Battery? And with a multimeter, you can easily measure the electricity flow or the battery charge in other words. This is why, when attached to a circuit with an electronic device, electricity flows. In simpler terms, it is the pressure that causes electricity to flow from one direction to the other.Ī battery, no matter how small or how large, has this potential difference. Voltage is the electric potential difference, in scientific terms. Whether you did or did not pay attention in your physics classes back in high school, you most definitely know what voltage is. A multimeter is a device that can measure the voltage of any battery along with electricity flow (current), resistance, and others.
