18650 lithium battery parameters

18 is a diameter of 18mm, 65 is a height of 65mm, and 0 is a cylindrical battery.

The nominal voltage of a single cell is generally: 3.6V or 3.7V

Charging voltage is generally: 4.20V (4.2V-4.3V for lithium cobaltate)

The minimum end-of-discharge voltage is generally: 2.75V, lower than this voltage will easily lead to a serious drop in battery capacity or even scrapping.

The maximum charge termination voltage: 4.20V

Diameter: 18±0.2mm

Height: 65±2.0mm

Capacity: more than 1000mAh, the conventional capacity is 2200mAh-3200mAh. At present, LG has the highest battery capacity of 18650, which can reach 3600mAh, but the price is not low.

18650 lithium battery application:

The theory of 18650 battery life is 1000 cycles of charging. Due to the large capacity per unit density, most of them are used for laptop batteries. In addition, because 18650 has very good stability at work, it is widely used in various electronic fields: often used in high-end glare flashlights, portable Power supplies, wireless data transmitters, electric thermal clothing, shoes, portable instruments, portable lighting equipment, portable printers, industrial instruments, medical instruments, etc.
