Often, consumers don’t know what the power of their laptops is. When your device needs charging, you usually plug it into the available battery. While it may not be important for most consumers to know that most batteries actually contain some 18,650 lithium-ion battery cells.
The 18650 lithium-ion battery is larger in length and width than a standard cell. The number 18650 refers to the total length and thickness. You can also buy 18650 lithium-ion batteries online with absolute ease.

Many 18650 lithium-ion batteries will differ in length very slightly. This is mainly due to the additional protective circuit. The circuit helps prevent the battery from being over-discharged, as lithium-ion cells can easily be damaged if they run out of power below a certain voltage.
The protection circuit also prevents the cell from being recharged. These cells are very delicate. They must be handled with care, and as described above, never to be exceeded or charged beyond their threshold. They really can explode if treated badly!
In terms of performance, 18,650 lithium-ion batteries are also used in today’s long-range LED flashlights. In an application like this, only one cell is needed.
Flashlight manufacturers have designed many of their lights to be just slightly larger than the 18,650 batteries that power them. There are specialized chargers on the Internet to charge these powerful cells, especially when used in LED flashlights.
Most run on 18650 batteries, as well as a variety of other lithium-ion sizes. So it’s easy to see how 18650 lithium batteries are finding their way into the hands of many modern consumers.
