AA and AAA batteries are one of the most common battery options for flashlights in 2022.
If you are curious what’s the difference between a AA battery and a AAA battery, then you have landed on the right blog post.
In this article, we will show you all the differences between an AA and an AAA battery.
That being said, let’s check out the matter in detail.
Difference Between AA & AAA Batteries
Although there are no upside differences between the AA, & AAA batteries, still, there are numerous things that you should have in your mind before you choose your next flashlight.
Below, we have mentioned all the differences in great detail. In this way, you can make a more mindful decision.
The main difference between a AA battery, and an AAA battery lies in the size. Both of these batteries have varying sizes, thus the AAA battery due to its smaller size is used in compact devices like modern TV remotes, EDC flashlights, etc.
On the other hand, AA batteries are used where you require more power.
The voltage of both of these batteries is exactly the same, which means that the power provided by these batteries is the same.
For High Capacity
For Low Capacity
The major difference between a AA, and AAA battery lies in their size. AA battery is larger in size as compared to a AAA battery.
Despite the fact, that there is not very much difference in the size, still, the difference is very much noticeable in both of the batteries.
AA batteries have a trivial dimension of 51mm in length and come with a diameter of about 0.55-inches. On the other hand, the AAA batteries have a length of 44mm, and a diameter of 0.41-inches.
The difference in the size of the batteries also affects the weight of the batteries. Typically, a AA battery weighs 23g, while a AAA battery weighs 11.5g.
Both the AA and AAA batteries produce exactly the same amount of voltage. To be more precise, a AA, as well as a AAA battery, produces 1.5V of current.
It’s the same amount of current produced by a D-sized cell. Hence, there is no difference in the voltage of all of these battery types.
Size matters, especially, when it comes to the backup time of a battery. AA batteries have a marginally better battery backup as compared to the AAA batteries, all thanks to the higher weight, and greater length of the AA batteries.
AA alkaline batteries do come with a 3000mAh battery, on the other hand, the AAA alkaline batteries come with 600mAh.
That means a AA battery in a normal case scenario would provide you with five times better battery backup, as compared to the AAA battery.
The battery backup of a AA battery is much better than a AAA battery, but on the other side of the story, a AAA battery is much more compact, and the usage of both of these batteries depends upon the outcome.
AA batteries are used in heavy-duty tools like wall clocks, powerful remotes, blood pressure monitors, etc, where you do not intend to save space.
While the AAA batteries are a good fit for compact devices like TV remotes, penlights, etc, where you do not need to have immense amount of power.
Frequently Asked Questions (FAQs)
AA Vs AAA Battery, Which One is Better?
Well, there is nothing better than the other in this regard, and depends upon the usage. If you are looking for higher power backup then you should get a AA battery, otherwise, AAA batteries are good enough for everyday usage.
How Much Voltage Does AAA Battery Produce?
AAA batteries produce 1.5 V. It’s the same voltage produced by AA batteries. The only difference is in the power backup of these batteries.
How Many Volts Does a AA Battery Produce?
A AA battery produces 1.5 voltages. It’s the same amount of voltage produced by AAA batteries, and D-sized batteries.
What’s the Difference Between a AAA Battery & AA Battery?
The main difference between a AAA battery, and a AA battery is in the size of the battery. So, the size of the battery affects the weight, and battery backup. On the other hand, the voltage of both of these battery types is exactly the same.
Can I Use AAA Batteries Instead of AA?
No, you cannot use AAA batteries instead of AA batteries, although the voltage of both of these batteries is the same, the difference between the size is very noticeable.
People get confused about the differences between a AAA battery, and a AAA battery, and have no clue which one is better.
The main difference between both of these batteries lies in the size, which ultimately affects the weight, and battery backup as well.
While both of the batteries share the same voltage and are used according to the size, and other requirements of the device.
