Are all 18650 batteries the same dimensions?
The 18650 cell is 18 mm in diameter and 65 mm tall; hence, its name 18650. Other cell form factors have standard sizes, too, but even though they’re standardized, many alternate cell designs haven’t achieved the same popularity. If the cell size never becomes popular, it can hardly be called a standard.

What is cell matching?
Matching of cells refers to the degree to which absorption cells give similar absorbance or transmission reading when empty or filled with water. A poor cell can appear matched because measuring a cell with no sample does not test the accuracy of the pathlength nor the dimensional quality of the windows.
