Frequently Asked Questions
Are CR2025 and CR2032 interchangeable?
Rarely. Same diameter, different thickness (2.5 vs 3.2 mm). Forcing a thicker CR2032 can crack a slim fob; a thinner CR2025 in a CR2032 tray often loses contact.
Is DL2025 the same as CR2025?
Yes. DL2025 is Duracell's brand label for a standard CR2025-size 3V lithium coin cell.
CR2025 vs CR2016 — which do I need?
Both are 20 mm wide. CR2025 is 2.5 mm thick; CR2016 is 1.6 mm. Match the code on the old cell — stacking or forcing the wrong height damages holders.
What devices use CR2025 batteries?
Thin car key fobs, some calculators, toys, and slim remotes. Always confirm the printed size rather than guessing from similar devices.
Should I always trust cross-reference charts?
Use this guide as a starting point, then confirm with your device manual or manufacturer. Voltage, chemistry, and physical fit must all match for safe operation.

Selection notes
If a CR2032 fits loosely or the door will not close, CR2025 may have been the intended size — measure height before buying. Prefer name-brand cells for key fobs.
