The type status describes documentary checks of core specifications, not every fact or suitability for a device.
Understanding CR123A before replacement
Identify the actual battery
CR123A is a documented Lithium / manganese dioxide primary cell with a nominal voltage of 3 V. Its reference diameter is 17 mm and its reference height is 34.5 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?
The dataset associates CR17345, 123, EL123AP with CR123A. The manufacturer may use a different label on the package. These references help identify the type; they do not certify the battery for a particular device.
Similar dimensions in this catalogue
No other type with this reference diameter is currently included in the catalogue. This does not prove that other sizes or alternatives do not exist.
What to check before replacing CR123A
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 CR123A. 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.

Common questions
What size is CR123A?
Ø 17 × 34.5 mm
Can CR123A be recharged?
No. Do not charge primary cells.
Can CR123A 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 CR123A.
