Generally, a fresh AA/AAA lithium or alkaline battery should read 1.5 volts or higher, while a used battery will likely read lower than this threshold. When testing the voltage on a AA battery, there are several factors to keep in mind. What Should the Voltage Read On a AA Battery? This simple test can help ensure that your AA batteries are functioning properly and providing reliable power to your devices.
If you do not see any indication of power being generated by the battery, it may be time to replace it. If there is an indication that power is flowing through the battery, it will likely be in millivolts (mV). Next, attach the black probe to the negative terminal of the battery. To test the functionality of a AA battery using a multimeter, you will need to set the DC setting on your meter and attach the red probe to the positive terminal of the battery. Testing the battery voltage on a multimeter is similar to testing it on a voltmeter.

How To Test a AA Battery With a Multimeter? Regardless of which type of AA battery you are testing, however, following these steps should give you an accurate indication of its level of charge and help you determine whether replacement is necessary. If you are testing an alkaline-type battery, you may need to perform this test multiple times before obtaining an accurate reading. If the voltage reading is low or zero, it may mean that your battery is no longer functional and needs to be replaced. Make sure to write down this reading, as it will indicate how much charge is left in your battery. To test a AA battery with a voltmeter, first, make sure that the voltmeter is on DCV and set it to 20.Īttach the red probe to the positive terminal of the battery, then attach the black probe to the negative terminal of the battery and wait for a reading. How To Test a AA Battery With a Voltmeter? Ultimately, whether you need to measure DC or AC voltage or perform other circuit testing functions, a good multimeter will serve you well. While they are both battery testers and measure electrical current, there are some key differences between the two.Ī voltmeter is designed to measure DC voltage, while a multimeter can measure both types of current and also has the ability to test other aspects of circuits, such as resistance and continuity.Īdditionally, while most voltmeters have only a few basic functions, multi-meters tend to be more versatile, providing users with many useful measurement options in one convenient device. What’s The Difference Between a Voltmeter And a Multimeter?Ī voltmeter and a multimeter are two common tools used by electricians and engineers to test the voltage output of different devices. So it’s important to carefully consider which test is most convenient for you and will provide you with the most relevant and reliable data. Ultimately, the method that is best depends on what specific information you are looking for about your AA battery. Alternatively, you can use a couple of other methods that don’t require a special meter. To do this, a voltmeter or multimeter is connected between the battery terminals. One of the most used methods is to measure the electrical resistance that the battery offers in its unloaded state.
