This setting will provide an accurate reading of the AA battery voltage. The AA battery voltage should be measured in the DC range, and the multimeter should be set to “2V”. Now that we know the basics of how to measure voltage with a multimeter, let’s talk about the correct multimeter setting to measure the voltage of a AA battery. What Is The Correct Multimeter Setting To Measure The Voltage Of A Aa Battery? If the multimeter reads somewhere around the value given on the battery’s label, the battery works fine. Once the probes are connected, take the reading on the multimeter. The red probe goes to the battery’s positive terminal and the black probe goes to the battery’s negative terminal. First, you need to connect the multimeter leads to the battery’s terminals. If the multimeter reads somewhere around the value given on the battery’s label, the battery works fine.īesides this, If you want to test if a battery works, you can use a multimeter. To test a battery with a multimeter, connect the multimeter leads to the battery’s terminals (red probe to the battery’s positive terminal and black probe to the battery’s negative terminal). Can You Test Batteries With A Multimeter?Ī multimeter is a device that measures electric current, voltage and resistance. OR the battery will “bounce” and fall over. One of two things will happen: The battery will “thud” on the surface and might even stay standing up. Take a AA battery, hold it over a hard surface (one that you won’t worry about scratching) about 2″ up, and drop the negative flat side unto the surface. But if the battery thuds onto the surface and stays standing, it’s probably still good.Īdditionally, The Drop Test. If the battery bounces or falls over, it’s likely no good. To do the drop test, simply hold a AA battery over a hard surface (like a table) about 2 inches off the ground, and then drop the negative (flat) side of the battery onto the surface. When it comes to testing AA batteries, the drop test is a quick and easy way to see if a battery is still good or not. To test an AA battery with a multimeter, you will need to set the multimeter to the correct setting and then touch the probes to the correct points on the battery. If you wanted to watch a youtube video that shows you how to test aa batteries with a digital multimeter? I have included a video below:Ĭan You Use A Multimeter To Test Aa Batteries?Ī multimeter is a versatile tool that can be used to test a variety of electrical components, including AA batteries. So we know that this battery has run out of charge. But when we connect the resistor, we can see that the voltage has dropped to 0.863 volts. When we take a measurement with no load, it oddly has a reading of exactly 1.5 volts. However, this battery is also rated at 1.5 volts. With the resistor connected, we take a reading of 1.547 volts, so this battery is still good. For example, this battery has a rated voltage of 1.5 volts. If the battery is still good, then the voltage level will only drop slightly. This way, current will flow through the resistor, and you can take a voltage reading as this occurs. In this case, I’ve just used some crocodile clips to connect the resistor between the probes like this. Then you connect the resistor between your two probes. So you take a resistor of around 100 ohms, but it doesn’t have to be exactly this value. To fully test the battery, you need to test it under a load condition to check whether it’s still useful. However, sometimes you could still get a voltage of around 1.5 volts even if the battery is of no use. When the battery is dead or dying, you get a lower voltage.įor example, this battery reads 1.07 volts, so it’s completely dead. The two values are close but usually not the same. You can see that the battery is rated at 1.5 volts, but when you test it, you get 1.593 volts. After that, you need to connect the red lead to the positive terminal and the black lead to the negative. Here I will explain you step by step process of how to test aa batteries with a digital multimeter? let’s see how to test aa batteries with a digital multimeter.įirst, you need to select the DC function on your multimeter.
