Frequently Asked Questions
Can I replace CR2016 with CR2032?
No in most devices. CR2032 is 3.2 mm thick versus 1.6 mm for CR2016 — nearly twice the height and likely to jam the compartment.
Is DL2016 the same as CR2016?
Yes. DL2016 is Duracell's equivalent label for the CR2016 size and 3V lithium chemistry class.
Why does my thin remote need CR2016 instead of CR2025?
The battery door and spring stack are designed for 1.6 mm. A 2.5 mm CR2025 may prevent the cover from closing or stress the plastic.
How long does a CR2016 last?
Capacity is modest (~90–100 mAh), so high-use remotes need more frequent swaps than CR2032 devices. Shelf life unused is still multi-year with quality brands.
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
Never force a thicker cell into a CR2016 slot — it can crack the case or damage contacts. Buy a spare pack; capacity is lower than thicker 20 mm cells.
