The Power of 18650 Lithium-Ion Batteries

  • October 16, 2020

Often times, consumers don't know what drives their laptop. When the device needs to be charged, turn it on, usually with the battery provided. Although most consumers may not find it important to know that most batteries actually contain some 18,650 lithium-ion battery cells.

When it comes to batteries, they are some of the most powerful cells available. Many devices use lithium-ion (or Li-ion for short) for power supply. For example, some electric shavers contain lithium-ion batteries. You can purchase 18650 li ion battery via

In terms of tension, it is usually 3.7. When fully charged, they collect up to 4.2 volts! And yes, these cells are really tiny too, sometimes in the form of a button that powers a very small device!

It should be noted that not ALL Li-Ions are rechargeable. For the purposes of this discussion, however, we will focus on those that exist. In particular, however, the 18650 lithium-ion battery is larger than a standard cell in length and width. The number from 18650 refers to the total length and thickness.

Like most battery cells, the charge is calculated before the milliampere hour (mAh). These mAh designations are often numbered 2200, 2400, 2600, 2900, and 3100, all of which refer to the amount of energy. The higher the number, the more energy the battery has.

The 18,650 lithium-ion batteries are also powerful when used in today's high-lumen LED flashlights. Only one cell is needed in such applications. The flashlight I mean when using a 18650 cell can produce light up to hundreds of lumens!
