AA batteries are larger in size as compared to AAA. The letter AA and AAAA do not stand any meaning, it is basically a way of expressing the dimension and nominal voltage. The main difference between AA and AAA batteries is the difference in size or dimensions and charge storage capacity. AA and AAA batteries are widely used in small electronic equipment. Be sure to go for a well-known brand when buying batteries, such as Duracell, Panasonic, or AmazonBasics, to ensure high quality and device safety.In this article, we will discuss the difference between AA & AAA battery. If you need batteries for a DIY project, then it is a good idea to go for double-As instead of triple-As solely because of their longer usage life. Slimmer and smaller slots mean the device uses triple-As, whereas a larger slot means it uses double-As. You can usually tell the compatible battery type of a device by taking a look at its battery slots. The battery type you should opt for more or less depends on which device you intend to use it with. Final Thoughts: Which Battery Type Should You Buy? You can also find budget options that cost much less, such as the AmazonBasics AA Batteries. AA batteries, on the other hand, can cost you around $20 to $40. So, a pack of triple As will cost you between $10 to $25, with a high-end option costing more. AAA batteries tend to be cheaper compared to double-As. The price of a battery pack is determined by its material, type, the number of batteries included, and brand. A double-A battery, on the other hand, will take much longer to lose its voltage capacity making it more long-lasting. Triple-A batteries, however, tend to lose some of their voltage capacity after a while. You will not notice much difference in power between double-As and triple-As initially. The output voltage of both these battery types is usually between 1.2 to 1.5 Volts depending on the building material and brand. The voltage of AA and AAA batteries is usually the same. Is the Voltage Of AA and AAA Batteries Different? In contrast, AAA batteries are used in devices that consume less energy or have a compact profile, such as clocks or TV remotes. AA batteries are heavy-duty, so they are used in devices that consume more energy, such as large radios and toys. Useĭouble-A and triple-A batteries also vary in terms of which devices they are used with. You can easily find the capacity of a battery on its packaging or on its label. For instance, a lithium battery can usually store much more electricity than an alkaline one. The capacity of a battery is affected a lot by what material it is made with. On the other hand, the capacity of a triple-A battery can be between 350 to 1200 milliampere-hour. A double-A battery typically has a capacity of 2000 to 3000 milliampere-hour. The capacity of a battery is measured in milliampere-hour. CapacityĪA batteries also have a larger capacity compared to AAA ones. A AAA battery also tends to be more slender, which makes it ideal for smaller devices since it won’t take up too much space. AA batteries tend to be larger than AAA ones both in height and length. The most obvious difference between a AA battery and a AAA battery is the size. Differences Between AA and AAA Batteries Size We’ll discuss these differences in detail to help you better understand both these battery types. These distinctions include capacity, cost, size, and uses. But have you ever wondered why some batteries are called AA and others are called AAA? Although both of these battery types look very similar, they have many differences. From futuristic clocks to vintage radios, we use batteries to power a myriad of our personal devices.
