Now that more devices are getting integrated rechargeable batteries, in the past 2 or 3 decades, the AA batteries have been the most used. These batteries were the best because of their ample capacity, size, and voltage. Their specifications enabled them to be one of the most used batteries. From toys, wall clocks, remote controls for different devices to other small electronics, all of them used the AA batteries as their primary power source. With the advancement of battery technology, rechargeable batteries were also made in the AA size. This leads to the further popularity of these batteries. Here we will elaborate on some interesting facts about the AA battery.

Are AA Batteries Different Sizes?

Here we will discuss some of the most common ones. Features of the different AA battery sizes. These are some of the features of all the different sizes of the AA battery.


The main difference between the different AA size batteries is their capacity. Here are some of the most common compositions of the AA batteries.

Alkaline batteries

These batteries have a capacity of 2700mAh. Being high capacity batteries, these are the best option for the power-thirsty things like children's toys.


These batteries have a relatively low capacity of only 1100mAh. These batteries have a low capacity that makes them a perfect option for things like remotes or clocks.


These batteries have a high 3000mAh capacity. The high capacity makes them good for the things that need power delivery for a long time. These can be the best for big toy cars because these batteries can last up to 3 times more than a normal alkaline battery.


This type of rechargeable AA batteries can provide about 2500mAh. The specialty of these batteries is that they are the best option for the devices where high current drainage is required by the battery.
