![]() ![]() In general, high-drain devices, such as digital cameras, require AA batteries, while low-drain devices, such as TV remote controls, are better suited for AAA batteries. Nonetheless, confusion can arise regarding the appropriate battery size for each device. They recognize that AA and AAA batteries are commonly used and can power various devices, ranging from remote controls to smoke detectors. Many individuals possess a basic understanding of how batteries operate. AA batteries will run more than two times the duration of AAA. You cannot compare 3000 mAh with 13000 mAh the difference is clear. AA batteries run longer than AAA because they contain more energy. Just as their sizes and capacities are different, the batteries have different function durations. The AA battery, being larger, packs more electrochemical material, delivering up to 2000 – 3000 mAh, which is three times more than the capacity of AAA. ![]() It delivers a capacity of 350-1200 Milliamps per hour. The AAA packs smaller electrochemical material, and therefore the capacity is limited. The two batteries have different capacities mainly because of their size difference. It is measured in ampere-hours or Milliamps per hour (mAh). The capacity of a battery refers to the amount of charge generated by the electrochemical reactions in the battery. AA batteries are 14.5 mm in diameter while AAA are 10.5 mm in diameter. They measure 44.5 mm (height) x 10.5 mm (diameter). AAA has a smaller diameter and length to fit in the smallest toys. Their standard size is 50.5 mm (height) x 14.5 mm (diameter). The AA is taller, wider, and generally larger than their AAA counterparts. They both have the same cylindrical shape but different dimensions. Size is the most noticeable difference between the two batteries. Here are the key differences between AA and AAA. Although both batteries perform similar functions, certain things set them apart. If you are looking for alkaline batteries, it’s easy to confuse AA with AAA batteries. Unlike AA batteries, they have a lower power capacity and are more effective for devices like remote controllers, smaller toys, and kitchen timers. They have also existed for over 100 years but came in four years after AA. They rank second in the popularity of dry cells after AA. On the other hand, AAA batteries, also known as Triple A, are smaller than AA, and the name doesn’t represent anything besides the type of battery sizes they are. These batteries are bigger than AAA and are mainly used for devices such as TV remotes, wall clocks, handheld kitchen gadgets, and flashlights. ![]() Instead, it’s a name for a standard battery size with nominal voltage. It is important to note that the name AA does not have a particular meaning. Although technology has significantly evolved and many devices use rechargeable batteries, dry cell batteries remain significant in powering most handheld devices. AA batteries have existed for over 100 years and have continued to be effective in modern-day devices. They contain a moist medium or paste charged with electrolytes, allowing electric current to pass through. AAA Batteries: OverviewĪA batteries use dry cell technology to power small electronic devices that do not require a lot of power. TV remote controls, wireless computer mice, small toys, handheld games, portable radios Remote controls, digital cameras, flashlights, toys, portable speakers In this article, we will compare the two batteries side by side, examine their key differences and discover how they are used in different devices. The amount of electrochemical materials in both batteries also varies, meaning they also deliver different power capacities. However, the two batteries differ in various aspects, such as size, use cases, and price. The two types of batteries provide a wide range of uses in our daily devices, like toys, TV remotes, wall clocks, and digital cameras. There are many types of alkaline batteries, but the most popular ones are AA and AAA. ![]()
