Understanding LR41 before replacement
Identify the actual battery
LR41 is a documented Alkaline zinc / manganese dioxide primary cell with a nominal voltage of 1.5 V. Its reference diameter is 7.9 mm and its reference height is 3.6 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 192, G3A with LR41. 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 LR41. Their height, chemistry or voltage may differ. They are comparisons, not approved substitutes:
What to check before replacing LR41
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 LR41. 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.

Other markings of this technical type
192 · G3A
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
Energizer 192 is documented as obsolete. Its observations are historical; Maxell independently supports the LR41 core specifications.

Common questions
What size is LR41?
Ø 7.9 × 3.6 mm
Can LR41 be recharged?
No. Do not charge primary cells.
Can LR41 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 LR41.
How does LR41 differ from PR41?
LR41 and PR41 have reference heights of 3.6 mm and 3.6 mm respectively, and nominal voltages of 1.5 V and 1.4 V. Their chemical systems are Alkaline zinc / manganese dioxide and Zinc–air. These comparisons do not establish a permitted replacement.
