The nominal voltage of a single section is generally 3.6V or 3.7V..
The charging voltage is generally 4.20V (4.2V-4.3V for lithium cobaltate).
The minimum discharge termination voltage is generally 2.75V V V. Below this voltage, the battery capacity will be seriously reduced or even scrapped.
Maximum charging terminal voltage: 4.20V V v.
Diameter: 18 0.2 mm
Height: 65 2.0mm.
Capacity: above 1000mAh, and the conventional capacity is 2200mAh-3200mAh. At present, LG has the highest battery capacity of 18650, which can achieve 3600mAh, but the price is not low.
18650 lithium battery uses:
The theory of 18650 battery life is that it can be charged 1000 times. Because of the large capacity per unit density, most of them are used for laptop batteries. In addition, 18650 is widely used in various electronic fields due to its excellent working stability, such as high-grade high-intensity flashlight, portable power supply, wireless data transmitter, electric heating clothes, shoes, portable instruments, portable lighting equipment, portable printers, industrial instruments, medical instruments and so on.
