As the 18650 batteries are a very practical form of lithium batteries, this is the reason that they are used in many things. Their major applications are in the portable devices that consume or supply power. Other applications include the vehicles, and some do it yourself projects.
Their wide range of applications makes them famous in all kinds of people who are interested in the products that use them. But their best part is that if you have a little technical and electrical knowledge about circuits, you can upgrade your product by yourself.
For upgrading your product from using the non-rechargeable batteries to using these rechargeable batteries, you need to do some modifications. But there is one problem that now you will have to add something to hold the batteries. For making the batteries stay in their place there are 18650 battery holders.
Do every 18650 battery need a holder?
So, the name 18650 battery is for a specific type of rechargeable battery. It means that any company or brand that names its battery with this name must follow the standards of 18650 battery in terms of size and electric power.
As every company follows the standards, here will be no difference in the size and power in the battery. The only difference will be in the quality of the battery.
People usually ask the is there a need to buy 18650 battery holder with the batteries. The answer to this is that if your device already has these batteries installed, then you will not need to have any holders attached to the device. But if your device does not have any place to fit the batteries, then you will have to buy these holders.
When you are working on your device, you can check if there is any place where you can put those batteries, but if you are working on a do it yourself project, then you will most probably need this holder to keep the batteries organized in your project.
Otherwise, most of the devices that you are upgrading will require you to have something to hold the batteries. For this, the 18650-battery holder is the best thing to attach to them, this is because these holders provide a very professional and elegant appearance. At the same time, some of them allow for the easy removal of the batteries.
We will discuss those types of the battery holders latter in the article.
What are the dimensions of the 18650-battery holder?
The dimension of holders depends on the dimension of batteries. Dimension of 1 18650 battery is 18 mm of length and width and 65 mm height. So, you can say that the holder that holds one battery will have dimensions 2 mm or 3 mm extended from each side. But this is not how it works with all the types of these battery holders.
The dimensions of the holder you are getting will also be depending on the type of the battery holder. If you are using the non-removable battery holder, then the dimensions can be according to your needs. Here you can easily add or remove batteries in each direction of utilizing space in the best way.
On the other hand, the removable battery holder has fixed dimensions for the number of batteries. This holder comes for one battery, 2 batteries, 3 batteries, and 4 batteries. The height, in this case, is extended by 10 for each battery while the sides remain 2 mm thicker than the original battery.
For an instance, the holder with 1 battery capacity will have approximate dimensions of 76 mm 20 mm and 20 mm. Here same methodology is followed by the holders for more batteries so you can multiply these dimensions with the number of batteries to get the approximation about the dimensions of these battery holders.
Some approximate dimensions are:
1.For 1 battery: 76 mm 20 mm and 20 mm.
2.For 2 batteries: 152 mm 40 mm and 40 mm.
3.For 3 batteries: 228 mm 60 mm and 60 mm.
4.For 4 batteries: 304 mm 80 mm and 80 mm.
These dimensions are approximate values because they can vary from manufacturer to manufacturer.
How do you use the 18650-battery holder?
Using the 18560-battery holder is very simple. You can attach them to your product with some adhesive tape or glue. For the connection, the holders with springs, you can easily insert the batteries. For the other type, you will need some soldering or spot welding to secure the connections.
Types of 18650 battery Holders and Their Usage:
There are 2 basic types of these battery holders. One allows easy removal of the batteries while the other doesn’t. Their distinct features are discussed below.
Non-Removable Battery Holder.
This type of 18650 battery holder comes one for each battery and it has clips on all four sides. With the help of these clips, you can attach one holder with others. By attaching batteries, you can create any shape or size of the batteries according to your needs. Here are some features of these batteries:
Different voltage configuration:
These holders allow you to use your batteries in any configuration according to your needs. If you have enough knowledge about using them to create high voltage, you can configure them in that way to get lower or higher voltage.
Different current configuration:
The same is the case with the configuration for different current ranges. If you want your batteries to output different amounts of current, you can connect them differently for different amounts of current.
Series or parallel circuits:
While some other holders do not give you the option to connect your batteries in the configuration according to your requirements, you can do this here to get different amounts of power from your batteries.
Any shape or size:
This type of battery holder has clips for attaching them with other batteries, you can attach them in almost any shape or size. This is very practical when you have limited shape.
Cons of this battery holder.
There are not many cons of this battery holder type. Although, there is one major negative thing that once you have connected the batteries, you cannot disconnect them easily. You have to de-solder them or pry them with pliers or cutters if you gave used the method of spot welding.
Removable Battery Holder
This battery holder has springs to hold the battery. This is good for the devices in which you have to keep removing batteries constantly for charging or other purposes.
Pros of this type:
The removal of the battery is very easy because of the usage of springs in this type.
Cons of this type:
You don’t have any options for custom voltage, current, size, or shape configurations.
In this article, we discussed the usage of the 18650-battery holder. The need of the holder was also well elaborated here. The dimensions of different types of holders were also discussed with the ways of using them. It will serve you as a guide for 18650 battery holder.
