The Power of 18650 Lithium-Ion Batteries

Quite often, consumers are not aware of what is powering their laptop computers. When the machine they need to be filled, those pairs, usually with the supplied battery. Although most users may not consider it important to know that most of the battery packs actually contains some 18,650 lithium-ion battery cells.

In terms of battery life, this is one of the most powerful cells available. Many devices use lithium-ion (Li-ion or for short), to the power supply. You can purchase 18650 lithium ion rechargeable battery via

Some electric shavers, for example, contains a Li-ion battery. In terms of voltage, 3.7 is often typical. With a full charge, they will pack up to 4.2 volts! And yes, these cells are also made very small, sometimes in the form of a button; supplying power to the device is very small!

It should be noted that not all Li-ion battery is rechargeable. But for purposes of this discussion, we focus on people. In particular, however, 18650 lithium-ion battery is larger both in length and width of standard cells. The numbers, 18650, refers to the overall length and circumference. Like most rechargeable cells, their power is rated in milliampere-hour (mAh).

18650 lithium-ion batteries also pack a punch, flashlight power-wise, when used in high lumen LED current. In applications such as this, only one cell is required. The flashlight I see when using 18650 cells, can generate up to hundreds of lumens of light! How much you ask? In some cases, as many as 800 lumens!
