Understanding LR54 before replacement
Identify the actual battery
LR54 is a documented Alkaline zinc / manganese dioxide primary cell with a nominal voltage of 1.5 V. Its reference diameter is 11.6 mm and its reference height is 3.05 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 189, LR1130, AG10 with LR54. 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
The following types share the same reference diameter as LR54. Their height, chemistry or voltage may differ. They are comparisons, not approved substitutes:
What to check before replacing LR54
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 LR54. 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 LR54?
Ø 11.6 × 3.05 mm
Can LR54 be recharged?
No. Do not charge primary cells.
Can LR54 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 LR54.
How does LR54 differ from SR1130?
LR54 and SR1130 have reference heights of 3.05 mm and 3.05 mm respectively, and nominal voltages of 1.5 V and 1.55 V. Their chemical systems are Alkaline zinc / manganese dioxide and Silver oxide / zinc. These comparisons do not establish a permitted replacement.
