## Questions & Answers

**Q: What is the difference between these and 2032 batteries?**
A: 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.

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

**Q: What diameter and length are these?**
A: CR123A are 34.5mm long by 17mm diameter.  CR2 are 27mm long by 16mm diameter.

**Q: Is the 3.6v the same as 3v**
A: That is usually a significant difference. "Coin cell" batteries this size are usually 3v, 3.6v batteries are usually much larger.
