Although there are no exact equivalent batteries to the CR2025, there are multiple batteries that may act as suitable substitutions. The CR2016 and CR2032 are exchangeable with the CR2025, but users must consider space limitations.
The CR2016, CR2025, and CR2032 cell batteries all have the same voltage. The diameter of each battery is the same, at 20 millimeters. However, the CR2016 is 1.6 millimeters thick, while the CR2032 is twice as thick, at 3.2 millimeters. The CR2025 measures 2.5 millimeters in thickness. The size differences allow the CR2032 to hold more lithium-based chemicals and provide 240 milliamps. The CR2016 can hold up to 90 milliamps, while the CR2025 can hold up to 160 milliamps.
