You can get AA Batteries as both Primary and Secondary types. Irrespective of the chemistry of the cell, all AA Batteries are “Dry Cells” as their electrolyte is not liquid (usually a semi-solid gel or paste). Coming to the flat negative terminal, its diameter must be at least 7 mm.ĪA Batteries have only one cell in them but they can have different anode, cathode or electrolyte chemistries and compositions. The height of the positive terminal must be at least 1 mm and its diameter can be up to 5.5 mm. They are the height and diameter of the positive terminal and the diameter of the negative terminal. The diameter of the AA Tube is 13.5 mm minimum and 14.5 mm maximumĪpart from these two, there are two other important dimensions associated with AA Batteries.The height or length of the AA Tube is 49.2 mm minimum and 50.5 mm maximum.The shape of an AA Battery is a small cylinder and hence when we talk about its dimensions, we usually mean its height and diameter.Īmerican National Standards Institute or ANSI formally standardized the size of AA Battery as follows: The term “AA” is only an indication of the size of the Battery i.e., its physical dimensions.

Have you ever changed the battery in a wall clock or TV Remote? What battery did you use? Chances of you shopped (either online or in a store) for a tiny cylindrical battery in the name of “AA Batteries”. There are several chemistries, electrode types, electrolytes, shapes, and sizes in both Primary and Secondary Batteries. Hence, we call Primary Batteries Non-Rechargeable Batteries or Disposable Batteries and Secondary Batteries as Rechargeable Batteries. While recharging, we apply electrical energy to rearrange the chemistry of the cells so that we can use them once again. While using Secondary Batteries, we use their chemical energy to provide electrical energy to a load.

In contrast to this, in a Secondary Battery, we can reverse the electrochemical process by “recharging” them. So, we have to discard these batteries and replace them with new batteries. In a Primary Battery, the electrochemical process is irreversible i.e., once we utilize all its chemical energy, there is no way to reverse it. The basic classification of batteries consists of only two types Primary and Secondary. Technically, a battery consists of one or more cells, the basic electrochemical unit that is made up of electrodes (anode and cathode) and an electrolyte. What is a Battery? A Battery is an electrochemical device that converts chemical energy to electrical energy.

Can We Use AAA Instead of AAA or Vice-Versa?īefore jumping into the AA vs AAA batteries comparison, let us take things slow and have a brief understanding of battery.

Here, we will understand the basics of both AA and AA Batteries, find out their differences, and many more things. To be specific, we are talking about AA and AAA Batteries.Įven today, we find ourselves constantly replacing (and sometimes recharging) these tiny batteries from our wireless mice or keyboards, wall clocks, remote controls, flashlights, test and measurement equipment, etc.Īs these batteries play an important part in our lives, we decided to make a simple guide comparing AA vs AAA Batteries.

We are not talking about fancy smartphones or tablets with Lithium-ion batteries but a much more “millennial”.

While electric cars and solar power systems are generally the “larger” applications of batteries, we have the small and portable set of applications as well. But the technological advancement in the last couple of decades has been tremendous. As we are searching for ways to reduce carbon emissions, the combination of renewable energy and batteries is the epicenter of all this.
