The nominal voltage for a single section is generally 3.6V or 3.7V

　　The charging voltage is generally 4.20V (lithium cobalt oxide is 4.2V-4.3V)

　　The minimum discharge termination voltage is generally 2.75V, which can lead to a serious decrease in battery capacity or even scrapping if it is lower than this voltage

　　Maximum charging termination voltage: 4.20V

　　Diameter: 18 ± 0.2mm

　　Height: 65 ± 2.0mm

　　Capacity: Above 1000mAh, the conventional capacity is 2200mAh to 3200mAh. Currently, LG has the highest capacity for 18650 batteries, which can achieve 3600mAh, but the price is not low.
