Reference dimensions are not universal manufacturing tolerances. Check the actual cell and holder.
Overall envelope is not a verified terminal layout or fit.
The type status describes documentary checks of core specifications, not every fact or suitability for a device.
Understanding BR425 before replacement
Documented battery characteristics
BR425: Lithium / polycarbon monofluoride, 3 V, Ø 4.2 × 25.9 mm. These are reference battery dimensions, not a verified device fit. Cell and battery pack shapes, contact layout and charging requirements can differ.
This is a primary battery; never attempt to recharge it.

Other markings of this technical type
BR-425
These markings resolve to this type in documented sources. The exact variant and device requirements still matter.
Conditional replacement: review requirements
No conditional cross-type relation is recorded.
Known obstacles to direct replacement
No explicit obstacle is recorded here; that is not evidence of compatibility.
Other type pairs without a recorded assessment
This pair has not been assessed. No compatibility conclusion is available.
No automatic replacement recommendation. Device compatibility has not been verified. Dimensions alone do not prove that a battery fits or works.
Documentary limits
BR425: The cited figures and notes are product-specific. Do not treat them as universal parameters or verified replacement instructions. Published technical records: Panasonic BR425; pin tip; manufacturer-specific capacity; maximum overall envelope. Device-level compatibility must be verified separately.
