What is the voltage of an 18650 battery?

The numbers 18650 in the 18650 lithium battery represent the external dimensions: 18 refers to the battery diameter of 18.0mm, and 650 refers to the battery height of 65.0mm. The common 18650 batteries are divided into lithium-ion batteries, lithium iron phosphate batteries, and nickel hydrogen batteries. The voltage and capacity specifications are: nickel hydrogen battery voltage is 1.2V, common capacity is 2500MAH, lithium-ion battery voltage is 3.6V, common capacity is 1500MAH-3100MAH.

Because 18650 can only represent the shape of a battery, the same shape has different voltages. Lithium ion batteries 3.7, iron phosphate 3.2, nickel hydrogen batteries 1.2, nickel cadmium batteries 1.2, and so on.
