Difference Between AA and AAA

AA vs. AAA

AA and AAA are battery designations that are used to indicate the size and potential charge capacity of certain batteries. The most significant difference between the two, is their size. AAA batteries are smaller compared to AA. This is important, as battery operated devices often use only one specific size. Although you cannot fit an AA battery on an AAA slot, you may be able to find adaptors that can make an AAA battery fit on an AA slot.

AA and AAA batteries carry the same amount of voltage, as do bigger batteries, like the D type. This is because they are basically just a single cell. 9 Volt batteries utilize six cells in a series to come up with the higher voltage. The smaller size of the AAA batteries means that there is a smaller amount of electrochemical material, which contains that electric charge. Although this directly translates to a smaller amount of charge in a AAA battery, this may not always be the case, as there are high capacity AAA batteries that might surpass the capacity of a standard AA battery.

The usage of AA and AAA batteries often varies, and there are no set standards for when to use one over the other, but you are more likely to find that devices which consume a lot of power, use AA batteries. Examples of high consumption devices, are battery operated toys and small electric torches. These devices also use more than one AA cell to raise the voltage, or to increase the operating time. AAA batteries are often found on low power, or portable devices, that don’t consume too much power. Clocks and remote controllers are good examples of devices that don’t need frequent battery changes.

For rechargeable batteries, you would need a charger that is suited for your batteries, but in case you have both AA and AAA batteries, you can find chargers that can charge both types. They have a movable part that uses a spring to push the battery tightly into place. AA and AAA batteries share the same electrical characteristics, and the charger would not need to treat them differently.

Summary:

1. AAA batteries are smaller compared to the AA.

2. AAA batteries carry a smaller amount of material compared to the AA.

3. AAA batteries may carry a smaller amount of charge compared to the AA.

4. AAA batteries are commonly found in small, and low power devices, while AA batteries are for devices that consume more power.
