There are many models of cylindrical lithium-ion batteries, such as 10440, 14500, 16340, 18650, 21700, etc. Cylindrical lithium-ion battery cells: Usually represented by five digits, the first two digits refer to the cell diameter, and the last three digits refer to the cell height. For example, 14500 refers to AA batteries, which are approximately 14mm in diameter and 50mm in height.

10440 battery

The 10440 battery is a lithium-ion battery with a diameter of 10mm and a height of 44mm. It is the same size as the commonly referred to as the No. 7 battery, and its capacity is generally very small, only a few hundred mAh. It is important for applications in mini electronic products. For example, flashlights, mini speakers, amplifiers, etc.

14500 battery

The 14500 battery is a lithium-ion battery with a diameter of 14mm and a height of 50mm, which has always been referred to as the size of the 5th battery. This type of battery is generally 3.7V or 3.2V, with a nominal capacity of slightly smaller than the 10440 battery, usually 1600mAh. It has excellent discharge performance and is most important in consumer electronics applications, such as wireless audio, electric toys, digital cameras, etc.

16340 battery

16340 battery is a type of lithium-ion battery with a diameter of 16mm and a height of 34mm. Due to its lower height and relatively small capacity, it is often used in high-light flashlights, LED flashlights, headlights, laser lamps, lighting fixtures, etc
