3 Advantages of a 18650 Battery

 Today, a 18650 battery is used in a variety of electronic devices, such as DSL cameras. What make these units so popular are three main characteristics: long service life, high energy density, and low cost. In these three areas, these units offer the best performance. Given below is the description of these three advantages of these units. Read on to find out more.

1) Cost Factor

As far as cost is concerned, you may have to spend a bit more money to buy a lithium-ion battery pack. But if you compare the operational cost of these units with that of the counterparts, you will be amazed to know that the cost is three times less.

For instance, gasoline cars cost three times more than electric cars. The high capital cost is due to the inclusion of cobalt and nickel in the metal oxide mixture. Therefore, these units cost up to 6 times more than your regular lead-acid ones.

2) Energy Density

The energy density of a 18650 lithium-ion battery pack is a lot higher than that of other technologies out there. The energy density is affected by the storage medium. Today, researchers are looking for a way to switch the storage medium to silicon.

In this case, the density of energy will go up by about 4 times. A major disadvantage of silicon is that it may trigger great contraction and expansion during every cycle. Therefore, only 5% silicon is used in combination with graphite.

3) Longevity

Longevity is another major advantage of these units. Your old laptop battery won't last more than a year. However, today's laptop batteries can be good for up to three years or longer. This is what these units are so popular among a lot of users and manufacturers.

Testing Method

The testing phase of these battery packs can help determine the capacity of the cells so you can form a pack. If you want to run a test, all you need to do is get a voltmeter, four trays, and an RC charger. You can use your voltmeter in order to test the cells and get rid of the ones that read below 2.5.

You can use the Intel charger to connect the cells. It will charge them at a rate of 375 milliamp/hour. In this case, if you connect two cells, each one will get 750. Now, you can mention the capacity on each unit. You can then group them based on the capacity parameter to use in different batteries.
