Can you substitute a CR 2025 battery for a CR 2032?

No, you cannot substitute a CR 2025 battery for a CR 2032. While both batteries have the same diameter of 20 mm, the CR 2025 is 2.5 mm thick, while the CR 2032 is 3.2 mm thick. This difference in thickness can prevent the CR 2025 from making proper contact in devices designed for the CR 2032, potentially leading to malfunction. Always use the specified battery type for your device to ensure optimal performance.
