First and Second Digits: These digits represent the diameter of the cell in millimeters. For example, “18” indicates an 18mm diameter.
Why do some lithium battery sizes end in ''0''? In the five-digit code (like 18650), the ''0'' at the end simply tells the manufacturer that the cell is cylindrical.
These numbers are more than just labels; they provide specific details about the physical dimensions of the cells, which in turn influence the battery''s performance, energy
Cylindrical lithium-ion batteries are typically represented by five digits; the first two digits refer to cell diameter, the third and fourth digits indicate physical length, and the fifth digit
The numbers on a lithium battery provide important information about the battery''s dimensions or capacity. For Cylindrical Batteries (e.g., 18650): The numbers refer to the battery''s physical size.
