There are different types of batteries that help us power our devices without hooking them up with wires all the time. AAA batteries are one of the most common types of batteries when it comes to consumer electronics’ remotes as well as toys. Apart from these applications, these batteries have a wide range of applications when it comes to DIY projects.
The best thing about these AAA batteries is that they come in both rechargeable and non-rechargeable options. So, if you are looking to know about these batteries you are at the right place as here, we will be elaborating on all the important factors about these batteries.
AAA Battery Dimensions
AAA batteries are the most common type of cylindrical batteries. They are mostly used in remotes for televisions as well as multimedia devices. Apart from that, these are used in desk clocks as well as wall clocks. When it comes to the dimensions of these batteries, they provide an amazing power to size ratio. Here are all the dimensions of these batteries that you must know.
The Height of AAA Batteries
These batteries have their positive terminal which is a little bit raised while the negative terminal is flat. So, including the terminals’ height the total height of this battery can be measured as:
45 millimeters
4.5 centimeters
1.77 inches
It is important to consider that this height is not the whole height as when you put them in their holder the height further increases.
The Diameter of AAA Batteries
When it comes to the diameter of these batteries they are measured as:
10.5 millimeters
1.05 centimeters
0.41 inches
The same is the case with the diameter of the battery that when you put them in their holder the dimensions increase a bit. However, the difference is not as much as that of height.
What to consider when using these batteries?
When you are using these batteries especially for some of your DIY projects it is important to consider that the dimensions of the battery pack will exceed the real size of the batteries. So, you must make all the calculations according to the overall size of the holder with the batteries installed. More about the holder dimensions in the next section.
AAA Battery Holder Dimensions
When it comes to buying the holder for an AAA battery you get a lot of options ranging from one battery to 4 batteries. The dimension of the holder will be different according to the number of batteries.
Factors That Will be Affecting the Dimensions of the Holder
There are not a lot of things, but the few things can make a huge difference if you are looking to stay tight on size. So, the following are some important factors that will be increasing the size of the holder in comparison with the battery size:
The spring is there to keep a hold of the battery, so it does not fall out on its own.
The spacers between batteries so that battery surfaces do not touch one another.
The Dimensions of the AAA Battery Holder
As there are different types of battery holders when it comes to selecting the AAA battery holder. Here we will be considering the example of a holder that comes with a capacity of 3 batteries.
Height of the holder
The following are the measurements for the height of the holder:
57 millimeters
5.7 centimeters
2.24 inches
Width of the Holder
The following are the dimensions of the width of the holder
37 millimeters
3.7 centimeters
1.45 inches
Depth of the Holder
The following are the dimensions of the depth of the holder
13 millimeters
1.3 centimeters
0.51 inches
Whenever you are looking to work with these batteries having a holder will be necessary, so it is important to consider the dimensions. If you are working with 3 batteries, then you can go with these measurements. Otherwise, the measurements will be different. Another thing to consider is that there can be slight changes depending on the manufacturer of the holder.
What is The Circumference of a AAA Battery?
Calculating the circumference of the AAA battery needs you to know the diameter. Well, the following are the diameter measurements of the AAA battery:
10.5 millimeters
1.05 centimeters
0.41 inches
Now that you have the diameter, multiplying it with Pi will give you the exact circumference of the battery. In this case, the circumference of the AAA battery will be:
32.9 millimeters
3.3 centimeters
1.29 inches
One very important thing to consider is that the battery dimensions can differ depending on the manufacturers. Some of them use a plastic sheet to cover the battery while some use a metallic sheet. So, if you are looking to calculate the exact measurements of the battery you can get its diameter measurements and then multiply it with Pi.
Why is it important to see the circumference of the AAA battery?
Checking the measurements like the circumference of the AAA battery is not that important if you are looking to use them with some production quality thing. The reason is that those devices are mostly made with a generic size so all brands can fit inside that battery.
However, if you are looking to insert these batteries in one of your projects that can be a battery charger or some other product then you need to be precise. Moreover, additional precision about size is needed when you are 3D printing the battery holder and you are trying to be as tight on space as possible.
So, make sure to get all the measurements right and you will never face any issues regarding the battery holder size ever again.
Conclusion
Although the AAA batteries are pretty simple when it comes to using them in consumer products, when you go a little on the DIY side the dimensions can be very important for you. So, now we hope that you know all about the dimensions of the AAA battery as well as the holder made for it. In any case, you can check the measurements of what you have for additional precision.
