The AA and AAA battery types are commonly used in portable devices such as toy controllers, computer mice, and cameras. However, many people confuse the two. This article aims to clear up any confusion and provide insightful information about these battery types.
1 Size Difference
The first notable difference between AA (2A) and AAA (3A) batteries is their size.
AA batteries (2A) typically measure between 49.2 and 50.5mm in length, weigh around 23 grams, and have a diameter ranging from 13.5 to 14.5mm.
On the other hand, AAA batteries (3A) are smaller, with a length of 44.5mm and a diameter of 10.5mm.
This noticeable size difference makes it easy to distinguish between the two types just by looking at them.

2 Capacity Difference
Both battery types produce 1.5V of electricity from their chemical reserves. However, due to their size difference, AA batteries generally have a higher capacity and longer lifespan than AAA batteries.
AA batteries will last longer, which is why they are often preferred for devices with continuous or long-term use, such as wall clocks or remote controls.
The capacity difference between 2A and 3A batteries
There are approximately 300 different battery sizes on the market today, which is 12 times more than the number of available letters in the alphabet. This has led to some batteries being named “sub-C” and “A23”.
In many places, AA batteries are also known as E91, MN1500, 815, KAA, AM3, 15A, LR6, or SUM1.
With this new knowledge, you should now be able to easily differentiate between 2A and 3A batteries and choose the right type for your devices.
