18650 2200mAh 3.6V

Today the 18650 battery is used in various electronic devices such as DSL cameras. These devices are famous for three main characteristics: long lifespan, high energy density, and low cost. These devices provide the best performance in these three areas. Below is a description of the three advantages of these units. Read on to find out more.

Cost factor

You might have to spend more money to buy a lithium-ion battery in terms of cost. But if you compare the price of operating such units with the cost of analogs, you will be surprised to learn that the cost is three times less.

For example, gasoline-powered cars cost three times the price of electric vehicles. The high cost of capital is associated with cobalt and nickel in the metal oxide mixture. Therefore, such units are up to 6 times more expensive than conventional ones containing lead-acid.


Durability is another crucial advantage of these units. An old laptop battery won't last more than a year. However, modern laptop batteries can last up to three years or more. That is why these devices are so popular with many users and manufacturers.

Energy density

The energy density of the 18650 lithium-ion battery is much higher than other existing technologies. The carrier influences the energy density. Researchers are currently looking to turn data storage media into silicon.

In this case, the energy density will increase by about 4 times. The leading disadvantage of silicone is that it can cause significant contraction and expansion during each cycle. Therefore, only 5% silicon is used with graphite.

Why use a 18650 battery?

It is a very powerful lithium-ion battery. It is suitable for charging some larger items and keeps power, so you can enjoy this product. We mentioned several times above that you can use 18650 batteries. This battery provides hours of juice, so you don't have to worry about running out of products. It is rechargeable, which cuts down on the costs you have to spend.

Test Method

This phase of testing battery packs can help you determine the capacity of the cells so you can reassemble the battery. If you want to take the test, all you have to do is get a voltmeter, four trays, and an RC charger. You can measure the voltmeter to check the cells and eliminate those that read less than 2.5.

An Intel charger can be used to connect the cells. It is charged at the rate of 375 mAh. If you join two cells, each will get 750. Now you can specify the capacity in each unit. Then you can group them by capacity parameter for use in different batteries.

Almost all virtual devices these days use lithium-ion batteries as their primary power source. There is a minor alteration in the chemical composition. Depending on energy density and usage, the life cycle of these devices can vary.


In brief, these are some main advantages of this type of battery. We hope you find this prose helpful enough to understand this technology better.
