Understanding CR1212 before replacement
Identify the actual battery
CR1212 is a documented Lithium / manganese dioxide primary cell with a nominal voltage of 3 V. Its reference diameter is 12.5 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 CR1212. Do not assume that a similar-looking code is equivalent.
Similar dimensions in this catalogue
The following types share the same reference diameter as CR1212. Their height, chemistry or voltage may differ. They are comparisons, not approved substitutes:
What to check before replacing CR1212
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 CR1212. A missing compatibility relation means “not assessed,” not “compatible.”
How reliable are these specifications?
Core type characteristics were compared with primary material from at least two independent publishers. This does not verify all model-specific values or physical suitability.

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
CR1212: The cited figures and notes are product-specific. Do not treat them as universal parameters or verified replacement instructions. Published technical records: Kingway 20 mAh; Blue TaiYang 15 mAh (product-specific). Device-level compatibility must be verified separately.

Common questions
What size is CR1212?
Ø 12.5 × 1.2 mm
Can CR1212 be recharged?
No. Do not charge primary cells.
Can CR1212 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 CR1212.
How does CR1212 differ from CR1216?
CR1212 and CR1216 have reference heights of 1.2 mm and 1.6 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.
