The Energy 18650 Lithium-Ion Batteries

Quite often, customers are unaware of what's powering their notebook computers. If their machine needs charging, then they plug it in, typically using the battery pack. Even though most users may not consider it important to know, that most battery packs really comprise several 18650 ion battery cells. In battery conditions, these are among the most effective cells out there. Many devices utilize lithium-ion (or Li-ion for short), to provide electricity. A number of electric shavers for instance contain a Li-ion battery. In terms of voltage, 3.7 is frequently typical. With a full charge, they'll pack up to 4.2 volts! And these cells can also be made very small, sometimes in button form, supplying power to very tiny devices!

It should be noted that not ALL Li-ion's are rechargeable. However, for the point of this conversation, we are focusing on those that are.

Specifically nevertheless, 18650 lithium ion batteries tend to be larger both in length and width than ordinary cells. The numbers, 18650, refer to length and general circumference. Like most rechargeable cells, their power is graded in milliamp ere-hours (mAh). All these mAh designations are frequently abbreviated for example 2200, 2400, 2600, 2900, and 3100, which all relate to quantity of electricity. The higher the number, the more power the battery possesses.

Briefly return to general size... many lithium ion 18650's will differ ever so slightly in length (measured in millimeters). This is principally because of an extra protection circuit. The circuit helps to prevent the battery out of over-discharging, since Li-ion cells can easily become damaged when their electricity is drained under a particular voltage. The protection circuit also prevents the cell from being over-CHARGED as well. These cells are very sensitive. They need to be dealt with carefully, softly, and as described above, should never run-down too much, or be charged over and over their threshold. They can actually explode if severely mistreated!

18650 ion batteries additionally pack a punch, power-wise, when used in today's high lumen LED flashlights. In applications like these, just 1 cell is required. The flashlights for which I refer to if using a 18650 cell, can create up to countless lumens of lighting! How many you ask? In some cases, as much as 800 lumens! This is close to the identical quantity of light as a 60w (equivalent) CFL bulb can produce. These tools can be small enough to fit in a pocket, rather comfortably. Flashlight makers have made many of the lights, to be just slightly larger than the 18650 batteries that power it. One word of warning however, flashlights of the sort, if turned on top, can get very hot to hold. This largely depends upon the units' ability to dissipate heat, but also depends on the overall size of the light. Many, even though only five inches long, may only get reasonably warm to the touch.

Concerning charging these powerful cells, even when specifically used in an LED flashlight, special chargers are available throughout the net. Most will deal with a 18650 battery as well as a wide variety of other Li-ion sizes.

So, it's easy to see how a lithium 18650 battery, and Li-ion cells in general, have found there way to the houses (and hands) of many contemporary customers.
