CR2 Vs 123 Battery: What’s The Difference?
CR2 and CR123A batteries are both 3V lithium manganese dioxide (Li-MnO₂) single-cell batteries, but they differ significantly in physical dimensions and application compatibility. CR2 (15.6mm diameter × 27mm height) is smaller than CR123A (17mm × 34.5mm), making them incompatible in devices requiring specific battery compartment sizes. Both are non-rechargeable and optimized for high-drain devices like … Read more
