![]() ![]() Durationīecause of the difference in their size and capacity, there is also a difference in their functioning duration. The AA battery capacity measures up to 2000 – 3000 mAh. Because it is smaller, the AAA battery capacity is smaller than its counterpart.ĪAA batteries have a capacity of 350-1200 Milliamps per hour, while the much bigger AA batteries have more than three times the capacity of AAA batteries. Usually, a battery’s capacity is measured in Milliamps per hour (mAh), and the AA and AAA batteries are no different. They have a measurement of 10.5mm x 44.5mm. Meanwhile, the AAA batteries are smaller in length and diameter and more suitable for smaller, low-power devices. Although both batteries are cylindrical, their sizes are still different.ĪA batteries are larger, wider, and taller than their counterparts, measuring around 14.5mm x 50.55mm. Many things make these two batteries different, but the most obvious is their size. Below, you will find the list of how to differentiate between these two battery types. Since we know what these batteries are and their basic characteristics, we can now focus on what makes them different and similar. Comparison Between AA Batteries And AAA Batteries They are also used to power devices like small toys, kitchen timers, remote controllers, etc. Unlike AA batteries, though, they are used to power low-drain devices that require lesser capacity, such as portable equipment. Also known as the Triple A batteries, they are also standard-size single-cell and dry batteries. While the AA batteries were invented in 1907, the AAA batteries followed four years later in 1911. Of course, they are the 2nd most popular type of batteries after the AA batteries. Just like AA batteries, AAA in AAA batteries do not stand for any term instead are just an indication of what type of batteries they are. The AA batteries are considerably bigger than the AAA batteries. They are also very common they are the most common types of batteries being manufactured currently. The AA batteries are what one would call standard size, and they run on 1.5 voltage. Unlike some may think, the letters AA do not mean anything, nor are they abbreviations for any term. These batteries have existed for a while as they were invented more than 100 years ago. They are called dry cell batteries because they have balanced moisture that allows enough current to pass through. The Difference Between Rechargeable and Primary BatteriesĪA batteries are dry cell batteries that are used to power and help portable electronic devices run.Comparison Between AA Batteries And AAA Batteries.It is also similar to the A27 battery, which has the same 12 V nominal voltage and almost the same length but is smaller in diameter by about 20%. The A23 battery is close in size to the N battery, which has a voltage of 1.25 V to 1.5 V. ![]() Ī23 batteries are constructed of eight individual LR932 alkaline button cells enclosed in a wrapper. The higher voltage is necessary for the radio frequency- transmitting and receiving devices which A23 batteries often power. An A23 battery is an 8- cell device with a nominal voltage of 12 V. Design Īn A23 battery is cylindrical and approximately two-thirds the length of an AAA battery, measuring 28.2 mm long and 10.0 mm in diameter, with a typical weight of 8 grams. It is mainly used in small electronic keychain radio devices, such as keyless vehicle entry systems, home security systems, garage door openers, and Bluetooth headsets. ![]() The A23 battery (also referred to as 23AE, GP23A, V23GA, LRV08, 8LR932, 8LR23, MN21, L1028 or ANSI-1181A) is a dry battery consisting of eight LR932 cells, with a nominal voltage of 12 V. ![]() Battery format Left to right: AA, AAA, AAAA, E90 and A23 batteries An open A23 battery showing the LR932 cells with an intact battery ![]()
