This battery has a voltage of only 1.5 volts and an amp-hour rating of about 600 to 1600 mAh. These batteries are not as common as the Duracell or Energizer AA batteries, but they are still used in some devices. The Zinc Carbon AA battery is another type of AA battery. These batteries also have an alkaline cell. This is still a 1.5 volt battery, just like the Duracell AA, but the battery capacity for mAh is around 1100 mAh. There are also AA batteries with a smaller yet similar mAh, such as the Energizer Max AA battery. We also use these measurements when we are discussing how long a device will run on the battery before the battery needs to be recharged. These measurements are both used often when we describe the charge of energy that is held within a battery. In case that is a new term for you, a milliampere hour (mAh) is 1000th of an ampere hour (Ah). The Duracell AA battery has a voltage of 1.5 volts and an amp-hour rating of about 1800 to 2800 mAh (milliamps hours). Alkaline batteries are the kind that is known as primary batteries, and they cannot be recharged. This would be the Duracell Coppertop Alkaline AA battery. The most common AA battery is the Duracell AA battery. Let’s look at a few of the AA batteries available on the market today. The higher the amperage, the more current the battery can provide.Ī AA battery typically has an amperage of between 0.01 and 0.02 amps. The amperage of a AA battery is how much current it can provide. The voltage of a battery is how much potential energy it has, which means that the higher the voltage, the more potential energy the battery has. AA Battery Voltage and AmperagesĪA batteries are available in a variety of voltages and amperages. Kilowatt-hours (kWh) would be V x Ah / 1000. This means that the AA battery can provide 24 watts of power for one hour of use, or 12 watts of power for two hours of use. The formula for watt hours is:įor example, if you have a battery that is rated at 12 V and 2000 mAh, the watt hours would be: To calculate watt hours, you need to know the voltage and amperage of the battery. Watt hours (Wh) are a measure of how much energy is stored in a AA battery. The higher the amperage, the more power the battery can provide. It is measured in amperes (A), and it determines how much power the battery can provide. AmperageĪmperage is a measure of how much current can flow through a AA battery. The higher the cell voltage, the more current that can flow through the battery. It is measured in volts (V), and it determines how much current can flow through the battery. Voltage is a measure of how much potential energy there is in a AA battery. Here are a few additional terms to know: Voltage The chemical reaction produces electrons, which flow through the circuit and power your device. This process is known as electrochemical reaction, and it occurs when the positive and negative terminals of the battery are connected to a circuit. How Does a AA Battery Work and Additional Terms to Knowīefore you understand how many amps are in a AA battery, it is helpful to know how AA batteries work and the additional terms we will use in this article.Ī AA battery works by converting chemical energy into electrical energy. It is safe to say that batteries have been monumental in changing the world’s dynamic forever, and it’s hard to imagine what life would be like without them. AA batteries are also known as alkaline batteries, while AAA batteries are usually referred to as nickel-metal hydride batteries. It is different than AAA batteries in that it has a larger diameter and is taller. Today, AA batteries are still commonly used in a wide range of devices, from digital cameras to room temperature meters. By the early 20th century, AA batteries were being used in a variety of devices, including radios and flashlights. The AA battery was first invented in the late 19th century, and it was initially used in telegraphy.
