CR2425 battery: the name confusion, explained

CR2425 appears both as a standards designation on CR2430 datasheets and as a retail label for a thinner 24 mm cell. Understand the difference before buying.

The short answer

CR2425 is not a separate format in the manufacturer lineups cited by this catalog. The name appears in two different places, and neither makes it a drop-in replacement for a CR2430 device.

Where the name comes from

Manufacturer datasheets for the 24.5 mm × 3.0 mm lithium cell sold as CR2430 list the standards designation as ANSI/NEDA-5011LC, IEC-CR2425. The string refers to that cell; the product itself is engraved and sold as CR2430.

Some retailers list a physically thinner 24 mm cell under the CR2425 name. A thinner cell can sit loose in a holder designed for a 3.0 mm cell and fail to make contact, even though the diameter matches.

Practical reference

Start with the original marking and your device manufacturer's requirements. Similar appearance alone is not sufficient evidence of interchangeability.

What this catalog documents at 24 mm

Four 24.5 mm lithium formats carry manufacturer-linked records here: CR2412 at 1.2 mm, CR2430 at 3.0 mm, CR2450 at 5.0 mm and CR2477 at 7.7 mm.

None of them is labelled CR2425, and none is an approved substitute for another. Open the specific record and check its thickness against the device holder.

The safe check

Read the marking on the original cell or in the device manual. If it reads CR2430, use a CR2430. If a listing says CR2425, treat the designation line and the physical thickness as two separate questions, and measure before you buy.

How to check the holder before ordering

Measure the internal depth of the battery holder with a caliper and compare it with the documented thickness, not with the diameter alone. A visible gap, a loose cell or an unusually tight cover are all reasons to stop.

If the old cell cannot be identified and the manual is unavailable, contact the device maker with the device model. Guessing from a retailer label is how a 3.0 mm device ends up with a thinner cell that powers nothing.

Decoding CR2425 as a code

Coin-cell codes are positional: the letters indicate the chemistry family and the digits split into diameter and thickness. Read that way, CR2425 describes a 24 mm diameter cell with a 2.5 mm thickness, which is why some listings use it for a thinner 24 mm product.

On manufacturer datasheets the same string can instead appear as the IEC designation line for a 3.0 mm CR2430. The code alone does not settle which physical cell you are looking at; the printed product and its measured thickness do.

Where 24 mm lithium cells are used

Catalog records for this diameter list typical applications such as remote controls, small electronics and memory backup. Application lists are illustrative, not a fit approval.

A holder built for a 3.0 mm cell will not close on a 5.0 mm one, and a thinner 2.5 mm cell can fail to make contact. The device manual remains the governing source for both chemistry and thickness.

Sources & limitations

The linked manufacturer documents support the stated model-specific values; other advice is an editorial interpretation of safe identification and selection practices. Rated capacities belong to the cited manufacturer and test setup, not every brand sold under the same code. Manufacturer cross-reference lists do not grant device-specific compatibility approval.
