Are they interchangeable?
No — not interchangeableNo. Despite sharing the same 20mm diameter, CR2025 is 0.9mm thicker than CR2016. A CR2016 will sit loose in a CR2025 slot, and a CR2025 may not fit in a device designed for the thinner CR2016.
The verdict
Use the exact type printed on your old battery or in your device manual. The thickness difference matters for proper contact.
