Understanding CR2412 before replacement
Identify the actual battery
CR2412 is a documented Lithium / manganese dioxide primary cell with a nominal voltage of 3 V. Its reference diameter is 24.5 mm and its reference height is 1.2 mm. These are nominal reference dimensions, not a promise that every manufacturer has identical tolerances.
This dataset describes a non-rechargeable bare cell, without solder tabs or wires. A tabbed or wired assembly requires a separate fit check.
What markings identify this type?
No other designation has yet been independently recorded for CR2412. Do not assume that a similar-looking code is equivalent.
Similar dimensions in this catalogue
The following types share the same reference diameter as CR2412. Their height, chemistry or voltage may differ. They are comparisons, not approved substitutes:
What to check before replacing CR2412
Read the original device marking, verify nominal voltage and chemistry, compare diameter and height, and check the contacts and load requirements. Same diameter, identical voltage, or a familiar brand prefix alone is not enough to establish interchangeability.
The available data contains no affirmative device-specific fit test for CR2412. A missing compatibility relation means “not assessed,” not “compatible.”
How reliable are these specifications?
The principal characteristics are currently supported by one primary source. A full independent second-source comparison is still pending.

Other designations
These codes identify the same type family. Match the load variant, terminals and device requirements separately.
No additional documented designation.
Documented brands
Brand presence comes from product documents or documented code mappings; current availability is not checked.
Product-specific observations
Capacity belongs to an individual product and test regime. It is not a universal value for this battery type.

Replacement limits
Device compatibility has not been verified. Dimensions alone do not prove that a battery fits or works.
Replacement evidence by category
Other markings of this technical type
No additional documented designation.
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
CR2412: Only one manufacturer or an insufficient independent source supports the cited measurements. Published technical records: Panasonic CR2412. Device-level compatibility must be verified separately.

Common questions
What size is CR2412?
Ø 24.5 × 1.2 mm
Can CR2412 be recharged?
No. Do not charge primary cells.
Can CR2412 replace another battery?
Not on the basis of size or matching names alone. Check the exact device requirements and the directed compatibility notes. This catalogue does not contain a guaranteed device-fit recommendation for CR2412.
How does CR2412 differ from CR2430?
CR2412 and CR2430 have reference heights of 1.2 mm and 3 mm respectively, and nominal voltages of 3 V and 3 V. Their chemical systems are Lithium / manganese dioxide and Lithium / manganese dioxide. These comparisons do not establish a permitted replacement.
