Various types of cylindrical lithium battery classification

1. Cylindrical primary battery, mainly No.5, No.7 battery, other models are not introduced, specific lithium battery manufacturers;

No. 5 battery, the general size is: diameter 14mm, height 49mm;

The general size of No.7 battery is 11mm in diameter and 44mm in height.

Two, cylindrical lithium battery, the main models are 18650,16650,14500, etc

18650 means 18 millimeters in diameter and 65 millimeters in length. The number 5 battery model is 14500, 14 mm in diameter and 50 mm in length. Generally, 18650 batteries are used more in industry and less in civil use. It is common to use more batteries in notebooks and flashlights.

18650 is only the size of the battery model, according to the battery type can also be divided into lithium ion 18650, lithium iron phosphate 18650, nickel metal hydride 18650 (very rare), the common 18650 is lithium ion.

1, large capacity 18650 lithium battery capacity is generally between 1200mah~3400mah.

2, long life 18650 lithium battery service life is very long, normal use cycle life can reach more than 500 times, is more than twice the ordinary battery.

3, 18650 lithium battery performance is high, 18650 was born in 1996, after decades of development, 18650 lithium battery has realized fully automated production, battery voltage, internal resistance, capacity, self-discharge consistency is very good, is currently preferred by various industries; High temperature resistance performance, 65 degrees under the condition of power down efficiency of 99.99%. In order to prevent short circuit of the battery, the positive and negative electrodes of the 18650 lithium battery are separated. So the likelihood of it short-circuiting has been reduced to the extreme. You can add a protective plate to avoid overcharging the battery, which can also extend the life of the battery.

4, high voltage 18650 lithium battery voltage is generally 3.6V, 3.8V and 4.2V, far higher than nickel cadmium and nickel metal hydride battery voltage of 1.2V.

5, no memory effect in charge before the remaining power will not have to empty, easy to use.

6. 18650 lithium battery pack can be synthesized in series or combined

7, use a wide range of laptop computers, walkie-talkies, portable DVD, instruments, audio equipment, model aircraft, toys, cameras, digital cameras, new energy vehicles, medical industry and other electronic equipment.

8. Under the condition of the same brand, the price of Hongli battery is more advantageous. The various parts of battery have realized mature mass manufacturing, which greatly reduces the production cost, so the cost performance is a good choice.
