Multiple batteries may serve as viable replacements for the CR2025, despite the absence of a precise substitute. The CR2016 and CR2032 are interchangeable with the CR2025, however space limits must be considered.
The voltage of CR2016, CR2025, and CR2032 batteries is identical. Each battery has the same dimension of 20 millimetres. However, the CR2016 is only 1.6 millimetres thick, whereas the CR2032 is 3.2 millimetres thick. The CR2025 has a thickness of 2.5 millimetres. The CR2032 can retain more lithium-based compounds and provide 240 milliamps because to its larger size. The CR2016 has a maximum capacity of 90 milliamps, whereas the CR2025 has a capacity of 160 milliamps.
