Jul 13, 2020   Pageview:58

Let’s be honest here. Without batteries, many of our household appliances would be useless. Many consider battery as an outdated concept, but it is one of the things we cannot live without. That’s why it’s important for us to know and understand the batteries we use, or else we might create unnecessary problems. For this reason, this article decided to discuss all about battery type 18650. We will give an introduction to it, its application, and the performance of the battery.

Is 18650 battery the most popular battery type?

Battery type 18650 is not the most perfect battery in existence, but it sure is one of the most popular ones. After all, these batteries are the ones commonly used for household appliances.  Things such as remote TVs, flashlights, clocks, laptops, and computer mouse are few of the many objects that use battery 18650 as their source of energy.

However, some might actually wonder what battery type 18650 is. Basically, they are batteries that are made of lithium-ion. Hence, another name for battery type 18650 is a lithium-ion battery.

They are widely used not without reason. Battery type 18650 is known to be able to store a great amount of energy. In fact, it can store as much as 3000 mAh in one of the batteries. Their discharge rate is also pretty powerful, as they can give a consistent amount of energy for a certain period of time.

However, it does not mean that battery type 18650 does not have any setbacks. One of its main concerns is the fact that it’s a bit sensitive to heat. If it gets worse, there is a big chance that the battery suffers from overheating. For this reason, some batteries type 18650 have an outer layer or extra coating to protect the batteries from heat.

Another important matter that should be noticed is battery type 18650’s top. There are two kinds of tops, which are flat top and button top. Flat tops are literally flat ends, while button tops are the ones with “bumps” at the batteries’ end.


Most battery type 18650 use both types of ends for their batteries, but sometimes there are also batteries that use button top-only and flat top-only for their batteries. This can create a minor problem, as the batteries tend up to be too short or too long for the device. For this reason, it’s best to know which end your device will need.

Nevertheless, battery type 18650 remains popular until now. Although you might not see it, it’s everywhere. In fact, it might even be residing in your devices right now!

What can people use 18650 battery for?

As it has been stated before, battery type 18650 is commonly used for household appliances. However, you can use battery type 18650 for more than mere household appliances. Here are examples of some things  you can use with battery type 18650:

Portable device

When we talk about portable devices, they are literally things you can bring with you every day. Some of those things are smartphones, laptops, cameras, tablets, game consoles, flashlights, and many more.

It’s not surprising how portable devices rely on battery type 18650. After all, battery type 18650 is one of the few types of batteries that are small in size, making it available for most devices.

Electric vehicles

Believe it or not, but battery type 18650 can actually be used for vehicles too! Some of the vehicles that use battery type 18650 are electric cars, motorcycles, scooters, bicycles, wheelchairs, and many more.

It should be noted that these vehicles are actually electric vehicles, meaning that they do not run by using fuel. Instead, they use the power from battery type 18650 to run the electricity that ignites the vehicles.

It’s not illogical for electric vehicles to use battery type 18650. After all,  battery type 18650 can also be charged. Its chargeable nature is one of the reasons why battery type 18650 remains famous until today.

Of course, it doesn’t mean that all batteries type 18650 have the same life span. Everything depends on the amount of energy used by the electric vehicle every day.

Power tools

Last but not the least, we have power tools that use battery type 18650. They are things such as saws, whipper-snippers, hedge trimmers, and so on. Of course, they use battery type 18650 not without reason. After all,  battery type 18650 is the ones that do not require much space, so they can be slipped anywhere easily. Moreover, it gives lots of energy, the battery can give lots of power too. No wonder power tools use battery type 18650. Thanks to its rechargeable nature and nature of its power, you can use it many times for the power tools.

How is the performance of 18650 battery?

Battery type 18650 has great performance. The battery can last for a long time, depending on the device that you use. Moreover, the battery can also be recharged for at least 500 cycles, depending on the device too.

The reason for the battery’s strong lifespan is due to the amount of power it has. After all, it can hold around 3000 to 3500 mAh per battery. Since most devices use at least two battery type 18650, the resulting energy would be around 6000 to 7000 mAh for one device. Hence, the battery is able to power up many things for a long time.

However, it should be noted that not all battery type 18650 has the same life span. Again, everything depends on the device and the amount of time you use the device. The more you use the device, the more you will use the battery, hence the more energy you will use.

From here, we can assume that battery type 18650 can be used for a long time. If the battery dies quickly, it’s either the amount of time we use it and the energy the device uses. So If you need a long-lasting battery, you should definitely opt for battery type 18650.
