Introduction of Cylindrical Lithium Battery 18650

18650 means 18 mm in diameter and 65 mm in length. Generally, 18650 batteries are used more in industry, but few in civilian use. The common ones are also used in notebook batteries and high-end flashlights.

The 18650 is just the size of the battery. According to the battery type, it can be divided into 18650 for lithium ion, 18650 for lithium iron phosphate, 18650 for nickel metal hydride (rarely), and the common 18650 is for lithium ion.

1. The capacity of a large-capacity 18650 lithium battery is generally between 1200mah and 3400mah.

2. Long life The 18650 lithium battery has a long service life. The cycle life can reach more than 500 times in normal use, which is more than twice that of ordinary batteries.

3. High safety performance The 18650 lithium battery has high safety performance. The 18650 was born in 1996. After decades of development, the 18650 lithium battery has achieved fully automated production. The battery voltage, internal resistance, capacity, and self-discharge are very consistent. Well, it is currently the preferred model in various industries; it has good high temperature resistance, and the discharge efficiency is 100% under the condition of 65 degrees. In order to prevent the battery from short-circuiting, the positive and negative electrodes of the 18650 lithium battery are separated. Therefore, the short-circuit phenomenon may have been reduced to the extreme. A protection board can be installed to avoid overcharge and overdischarge of the battery, which can also extend the service life of the battery.

4. High voltage 18650 lithium battery voltage is generally 3.6V, 3.8V and 4.2V, much higher than the 1.2V voltage of nickel-cadmium and nickel-hydrogen batteries.

5. There is no memory effect. It is not necessary to empty the remaining power before charging, which is convenient to use.

6. It can be combined in series or parallel to form a 18650 lithium battery pack

7. Wide range of use: notebook computers, walkie-talkies, portable DVDs, instrumentation, audio equipment, model airplanes, toys, camcorders, digital cameras, new energy vehicles, medical industry and other electronic equipment.

8. In the case of the same brand, the price of the battery is more advantageous. The various parts of the battery have been manufactured in mature and large quantities. In the production cost, the production cost is greatly reduced, so the cost performance is the best choice.
