Features:
Standardized Size and Shape
The 18650 lithium - ion battery pack is based on a standardized cylindrical shape. The "18650" indicates that the battery is 18mm in diameter and 65mm in length. This standardization allows for easy integration into a wide range of devices. For example, in battery - powered flashlights, the cylindrical shape of 18650 batteries fits well into the flashlight's tube - like body, enabling a compact and efficient design.
The consistent size also makes it possible to use battery holders and charging devices that are specifically designed for 18650 batteries. Manufacturers can produce products with interchangeable battery compartments, which is convenient for users who may need to replace or upgrade their batteries.
High Energy Density
18650 Li - ion battery packs offer a relatively high energy density. They can store a significant amount of energy in a compact size. This means that for a given volume or weight, they can power a device for a longer period compared to some other battery types. For instance, in a portable power bank, using 18650 battery packs can increase the overall capacity and allow for more charges of a mobile phone or other small electronics.
The high energy density also enables the design of more powerful and longer - lasting devices. In electric vehicles, although multiple 18650 battery packs are usually needed, their energy - storing capabilities contribute to an extended driving range and better performance.
