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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable Coin Batteries with Long-Lasting Performance *by S***M on 20 May 2026* These Energizer CR2430 batteries have provided reliable and consistent performance across several small electronic devices.
