Description
This is 3.7V, Lithium Ion Battery. This is a standard naming convention for cylindrical lithium-ion battery cells. The “18” indicates the diameter of the cell in millimeters, and the “650” indicates the length of the cell in tenths of millimeters. So, an 18650 cell is approximately 18 mm in diameter and 65.0 mm in length.
Lithium-ion batteries like the CGR18650 are commonly used in various applications, including portable electronics, laptops, power tools, electric vehicles, and more. They offer a high energy density and rechargeability, making them suitable for devices that require lightweight and long-lasting power sources.
