The lithium-ion cylindrical battery comes in a wide range of sizes. The diameter of the cell is stated first, followed by its height. For example, the 14500 battery is (14 mm by 40 mm).

The 18650 battery is the most common however the 10440 battery, 14430 battery, 14500 battery, 14650 battery,16650 battery, 18500 battery, 22650 battery, 26650 battery, 32600 battery, and the 42110 battery are also frequently used for various applications.

Smaller cells may be used in a device like a toothbrush or a shaver, while larger sizes may be built into lithium-ion battery packs. The 20650 battery, 20700 battery, and 21700 battery are more recent developments, boasting a better volumetric energy density than predecessors.
