18650 battery lithium ion 2200mah

How is the capacity AH of the 18650 battery of the battery calculated? What about the capacity of 10AH?

18650 is the originator of lithium-ion batteries - a standard lithium-ion battery model set by Japan's SONY company in order to save costs. 18 indicates a diameter of 18mm, 65 indicates a length of 65mm, and 0 indicates a cylindrical battery.

The 18650 batteries used in general notebook computers usually have a capacity of 2200mAh (milliamp hours), which can be interpreted as: powered by 3.7V voltage and 2200mA (milliampere) current, it can be used for 1 hour (hour) capacity, which is the current multiplied by the number of hours. The result (mAh)

  in addition:

Anyone who has studied physics knows that W (watt, power unit) = V (volt, voltage unit) × A (amp, current unit), so you can calculate that the capacity of the 18650 battery is 3.7V × 2200mAh = 8.14Wh, So we know that the three-cell battery capacity is 8.14×3=24.42Wh, the four-cell battery capacity is 8.14×4=32.56Wh, and the six-cell battery capacity is 8.14×6=48.84Wh.
