What is the difference between these and 2032 batteries?

The first 2 digits represent the diameter of the battery in millimeters (mm). The second 2 digits represent the height (or thickness) of the battery in tenths of a mm. So a CR2016 is 20mm in diameter and 1.6mm high and the CR2032 is 20mm in diameter and 3.2mm high. They are both nominally 3 Volt batteries.

I have a welding mask that requires new batteries (cr2450)are their different sizes?

Hello, I believe that you will be alright as it is the same number (the number corresponds to different diameters of coin/flat batteries). The cr is the type of the battery itself - coin battery. Good luck

What diameter and length are these?

CR123A are 34.5mm long by 17mm diameter. CR2 are 27mm long by 16mm diameter.

Is the 3.6v the same as 3v

That is usually a significant difference. "Coin cell" batteries this size are usually 3v, 3.6v batteries are usually much larger.
