Icr18650 Batteries: All The Info

The lithium-ion batteries are very popular today and they can be found in many electronic devices, such as telephones, laptops, flashlights, etc. Their format can be different as well, so there are small cylindrical, large cylindrical, pouch or prismatic. When it comes to this specific category icr18650, these are not just the batteries, but the holders, charges, flashlights as well.  There are many types and brands you can choose from, but all depends on the performances you expect and the price you want to pay. Some of the most important brands of icr18650 batteries are Sanyo, Tenergy, LG, Samsung, Ultrafire with the wide range of products of this kind, but the bestselling are batteries with the power of 3.7V and 2600 mAh.

All of the icr18650 batteries, not just the batteries have a lot of benefits, that’s why they are so popular, and some of the things that people love about them, the most are:

  • The icr18650 batteries are mush efficient and last much longer than any other types,
  • There are so many shapes and sizes you can choose from, meaning that they can fit any electronic device,
  • They are not heavy like many secondary batteries,
  • On e thing that people love the most is that those batteries are rechargeable, so it is not necessary to buy another one when it’s empty,
  • Their self discharge rate is approximately 5-10% per month comparing to 30% of nickel metal hybrid batteries,
  • The components are environment friendly since there is no free lithium metal,
  • There is additional equipment such as holder or charger that provide a full performance of a battery.

Just like with any other product, it is important to know what exactly to look for in order to get the best product. When it comes to lithium-ion batteries, the most important is to know that they are safe for use, that they are simple enough for everyone, and that they can last longer than any other products of the kind. The expiration date is something that people usually connect with the food, but the batteries also have their durability and it not recommended to buy one if it’s expiration date is close. Those can be reasons enough to buy more expensive ones. The higher  price usually can guarantee the durability and safety, and when it’s about rechargeable batteries icr18650, it is possible to find all the features needed in just one product.

The three bestselling icr18650 products are actually batteries made by Tenergy, US company in the middle of the Silicon Valley. Buying not just one but 4 or 6 pieces can save the money and provide the quality at the same time. The Tenergy icr18650 batteries have those desirable features:

  • The nominal capacity is 2600 mAh, but the minimum needed 2450 mAh,
  • The nominal voltage is 3.7V but the cut-off voltage is 3.0V
  • Internal PCB protection with prevents the under- and over-voltage,
  • The energy density is much higher comparing to other batteries and they don’t weight too much,
  • Their dimensions are Diameter 18+/-0.2 mm, Height 66+/- 0.2mm,
  • The cycle life is 500 cycles,
  • The charge – Current = 0.5C mA Voltage = 4.2 V End Current = 0.01 mA, Discharge: Current = 0.5C mA End Voltage = 3.0V,
  • Must be taken care of very well since they can explode if mis-handled.

When it comes to bestselling brands of the icr18650 batteries, the top three companies are Tenergy, LG and Samsung. The features of their batteries are pretty similar, as well as the prices. The only thing different is that the Tenergy batteries have the PCB protection unlike the others two, and the LG and Samsung emphasize the safety of the batteries since they are Free from Leakage of Liquid Electrolyte.

The customers just love that batteries, and they usually use them for flashlights. They are highly recommended from most of the customers, especially because they have the PCB protection that seems to be needed all the time. The only disadvantage is that it takes about 12 hours to charge those batteries, but it’s not bad comparing to all the benefits.

How Does The Ion 18650 Lithium Battery Work?

Lithium is a metal that is highly reactive; therefore, it is also a metal with a very high potential for converting chemical energy into the needed electricity for digital equipment. In fact, in some lithium 18650 li battery cells, the electrochemical potential is five times greater than it is in battery cells that are made of lead and three times greater than the amount for alkaline cells. Lithium, too, is very flexible. As a result, it’s also a feasible metal to use in the designs of small cells, or the type of cells used in such electronic items as laptops, digital cameras and palmtop computers or PDAs.

Battery Specifications

A typical 18650 3.7v battery cell then is a cylindrical Li-ion cell which is lightweight. Most cells are around an ounce and a half in weight. General capacity is measured at 2,200 milliamps or 2.2 amps. Usually, any amount higher than this number causes one to question stability. The maximum charge is 2.4 amps while the maximum discharge current is 4.6 amps.

The Process of Ionization – How a Lithium Battery Works

As stated, in the case of a lithium battery, as with all batteries in general, chemical energy is transformed into electrical energy. This process begins when electricity is supplied to the battery by way of a battery charger, which subsequently becomes a conduit for the electrons. The negative charges combine with the molecules in the lithium and are forced between spaces in the metal’s crystal planes. The electrons then ionize the lithium. Ionization, as a result, causes the metal’s planes to become loaded to the extent that they maintain a constant flow of energy. It also breaks down the reactive properties of the lithium in the battery.

The Case for Lithium

Needless to say, to keep your laptops, notebooks, iPods, PDAs or digital cameras working without interruption, it’s important to charge your Li-ion batteries. Plus, lithium, as stated, is a highly reactive type metal. Therefore, you will always receive an adequate power supply if you use such a battery as a power source.

Keeping your Electronic Devices in Working Order

There are a number of 18650 battery cells and battery chargers on the Internet. Some of the best known brand names for lithium batteries and chargers include Sanyo, Panasonic, Samsung, Ultrafire and Tenergy. Tenergy offers consumers Li-ion battery cells as well as chargers. The universal plug-in charger made by the company is designed specifically for 18650 Li-ion batteries. Especially adaptable for traveling, you can carry the lightweight device with your other digital equipment and never have to worry about your batteries losing their ability to keep items running, such as your cell phone or laptop.  Therefore, you can plug in the charger anywhere in the world and have access to your notebook, laptop, or PDA without the worry that you will be without a personal means in which to communicate.

It’s helpful to understand how a lithium battery works and how the metal impacts our daily lives. Look on the Internet for all your lithium battery and charger needs.
