Thickness — 5.4 mm vs 3 mm
CR2354 is 5.4 mm thick; CR2330 is 3 mm. Holders are built for one stack height. The thinner cell loses spring pressure (“works only when I press the cover”). The thicker cell jams the door or bends the clip.

CR2354 vs CR2330: Same Diameter, Different Thickness
Same 23 mm diameter family. CR2354 is 5.4 mm thick; CR2330 is 3.0 mm thick. Capacity and door clearance both change with height.

Are CR2354 and CR2330 interchangeable?
Not interchangeable — match the height printed on your old cell.
A CR2330 vs CR2354 swap fails on thickness, capacity. If the door only closes when you force it, or the device works only while you press the cover, you have the wrong cell — not a weak spring you should ignore.
CR2354 vs CR2330 specs: thickness, capacity
They share 3 V and LiMnO2 and 23 mm diameter, which is why CR2354 vs CR2330 looks interchangeable on a store shelf. Highlighted rows are the ones that change the purchase: thickness, capacity.
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 CR2354 and CR2330 batteries
If you searched CR2330 vs CR2354, you are on the same comparison with the names reversed. The difference between CR2354 and CR2330 batteries is not the word “vs” — it is the specs that do not match after you ignore the similar photos.
Capacity — 520–560 mAh vs 255–280 mAh
Typical CR2354 capacity is 520–560 mAh. CR2330 is 255–280 mAh. Runtime only follows that gap inside the correct holder. Extra capacity in the wrong tray does not last longer — it often does not run at all.

How the size code works (CR2354 vs CR2330)
Coin and button codes are rulers, not brand slogans. The letters mark chemistry class. The digits encode size. CR2354 measures 23 × 5.4 mm; CR2330 measures 23 × 3 mm. Once you read the code that way, CR2330 vs CR2354 stops looking like a preference and starts looking like a fit check.
Can I use a CR2354 instead of a CR2330?
Usually no. CR2354 is 23 × 5.4 mm at 3 V (LiMnO2). CR2330 is 23 × 3 mm at 3 V (LiMnO2). Those are not the same part.
If the spent cell or tray said CR2330, specify that code. Forcing CR2354 can crack a cover, lose contact, or apply the wrong voltage.
Can I use a CR2330 instead of a CR2354?
Usually no. Going the other way does not fix a diameter, thickness, or voltage miss. CR2330 in a CR2354 holder has the same problem with the names flipped.

Brand labels and aliases
Retail packs hide the IEC size behind house codes. CR2354 also appears as DL2354, ECR2354. CR2330 also appears as DL2330. Those prefixes do not change the outline unless the chemistry letters change (BR, LIR, ML, PR).
How to identify CR2354 versus CR2330
You do not need a full datasheet to settle CR2354 vs CR2330. 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: CR2354, CR2330, 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: CR2354 is 23 mm; CR2330 is 23 mm.
- Measure thickness: CR2354 is 5.4 mm; CR2330 is 3 mm.
- Buy the matching code. Extra capacity or a thicker can only helps when the holder is built for that cell.
Choose CR2354 when…
- Label says CR2354
Choose CR2330 when…
- Label says CR2330
Compatibility and substitution
Same rule as CR2430/CR2450: diameter match is not enough.
Do not stack cells, grind a can, or use foil as a permanent spacer to fake CR2330 with CR2354. Read the stamp, then the spec table. If the door will not close without force, you have the wrong height or diameter.
CR2354 vs CR2330 FAQ
Why do the names look so similar?
IEC coin codes encode size. The last digits track height; the first digits track diameter.
I searched CR2330 vs CR2354 — is this the right page?
Yes. CR2354 vs CR2330 and CR2330 vs CR2354 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.
