CR2032 vs DL2032: What's the Difference?
DL2032 is Duracell's brand name for a standard CR2032 lithium coin cell. Dimensions (20 × 3.2 mm), nominal voltage (3V), and typical capacity are the same class of product.

Are CR2032 and DL2032 interchangeable?
Fully interchangeable. Buy either CR2032 or DL2032 from a trusted retailer.
Shop by a fresh name-brand pack of the same outline. The retail prefix (DL, ECR, AG, A76) is usually a label, not a new size. Confirm voltage and chemistry before you treat any “almost the same” listing as a drop-in.
CR2032 vs DL2032 specs
They share 3 V and LiMnO2 and 20 mm diameter, which is why CR2032 vs DL2032 looks interchangeable on a store shelf. Highlighted rows, if any, are the shopping differences. Matching rows are why the two names get searched together.
Read physical fit before capacity. Extra milliamp-hours only help when the holder is built for that cell. A “better” spec in the wrong tray is a mechanical or voltage mismatch, not an upgrade.

Difference between CR2032 and DL2032 batteries
If you searched DL2032 vs CR2032, you are on the same comparison with the names reversed. The difference between CR2032 and DL2032 batteries is not the word “vs” — it is the specs that do not match after you ignore the similar photos.

How the size code works (CR2032 vs DL2032)
Coin and button codes are rulers, not brand slogans. The letters mark chemistry class. The digits encode size. CR2032 measures 20 × 3.2 mm; DL2032 measures 20 × 3.2 mm. Once you read the code that way, DL2032 vs CR2032 stops looking like a preference and starts looking like a fit check.
Can I use a CR2032 instead of a DL2032?
Usually yes. CR2032 and DL2032 belong in the same holder class when voltage, chemistry, and outline match. Use a fresh name-brand pack.
If the spent cell said DL2032, CR2032 is the correct replacement only when the spec table shows the same size and voltage. A similar prefix (LIR, ML, BR, 14500) is not this swap.
Can I use a DL2032 instead of a CR2032?
Usually yes — it is the same pair in the other order. DL2032 vs CR2032 does not change fit or voltage.
Buy the fresher authentic pack. Counterfeit retail wrappers are a bigger risk than the extra letter on the can.
Brand labels and aliases
Retail packs hide the IEC size behind house codes. CR2032 also appears as DL2032, ECR2032. DL2032. Those prefixes do not change the outline unless the chemistry letters change (BR, LIR, ML, PR).
How to identify CR2032 versus DL2032
You do not need a full datasheet to settle CR2032 vs DL2032. You need the stamp, the tray, or a cheap pair of calipers. A store bin labeled only “button cell” or “3V lithium” will not do that work for you.
- Read the code on the old cell: CR2032, DL2032, and the brand prefixes that map to each one.
- If the print is worn off, check the tray, battery door, or user manual before buying.
- Measure diameter if the codes are gone: CR2032 is 20 mm; DL2032 is 20 mm.
- Measure thickness: CR2032 is 3.2 mm; DL2032 is 3.2 mm.
- Buy the matching code. Extra capacity or a thicker can only helps when the holder is built for that cell.
Choose CR2032 when…
- You are shopping generically for CR2032 / ECR2032
- Your device manual lists CR2032 without a brand preference
Choose DL2032 when…
- You prefer Duracell packaging / retail availability
- A store shelf only stocks DL2032 and you need a same-size 3V cell
Compatibility and substitution
Do not confuse DL2032 with rechargeable LIR2032 (~3.6V). Brand swaps among primary CR2032 cells are fine; chemistry swaps are not.
Do not stack cells, grind a can, or use foil as a permanent spacer to fake DL2032 with CR2032. Read the stamp, then the spec table. If the door will not close without force, you have the wrong height or diameter.
CR2032 vs DL2032 FAQ
Is Duracell 2032 the same as CR2032?
Yes. Duracell labels the cell DL2032; it is fully equivalent to CR2032 in size and nominal voltage.
Can I use BR2032 instead?
Same size, different chemistry (Li-CFx). Often OK at room temperature; follow industrial datasheets when BR is specified for temperature range.
I searched DL2032 vs CR2032 — is this the right page?
Yes. CR2032 vs DL2032 and DL2032 vs CR2032 are the same pair. Fit, voltage, and chemistry do not change when you flip the order.
Should I always trust a cross-reference chart?
Use this guide as a starting point, then confirm voltage, chemistry, and physical size with your device manual or the marking on the old cell.
