18650 lithium ion battery -凯发官方网站

18650, the earliest ancestor of lithium-ion battery, is a standard lithium-ion battery model set by japansony company to save cost. 18 represents 18mm in diameter, 65 represents 65mm in length, and 0 represents cylindricalbattery.

the common 18650 batteries are divided into lithium ion batteries and lithium iron phosphate batteries. the nominal voltage of lithium ion battery is 3.7v, the charging cut-off voltage is 4.2v, the nominal voltage of lithium iron phosphate battery is 3.2v, the charging cut-off voltage is 3.6v, the capacity is usually 1200mah-3350mah, and the common capacity is 2200mah-2600mah.

18650 battery life theory is 1000 cycles of charging. due to the large capacity of unit density, most of them are used for computer batteries. in addition to 18650 lithium battery, 18650 is widely used in various electronic fields because of its great stability in operation: it is commonly used in high-end strong light flashlight, portable battery, wireless data transmitter, electric heating warm clothes, shoes, portable instruments and meters, portable lighting equipment and portable printer, industrial instruments, medical instruments, etc.

wide application range:computers, walkie-talkie, portable dvds, instruments and meters, audio equipment, aircraft models, toys, video cameras, digital cameras and other electronic equipment.
