Understanding LR48 before replacement
Identify the actual battery
LR48 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 5.4 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 AG5, LR754 with LR48. 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 LR48. Their height, chemistry or voltage may differ. They are comparisons, not approved substitutes:
What to check before replacing LR48
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 LR48. 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.

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.

Common questions
What size is LR48?
Ø 7.9 × 5.4 mm
Can LR48 be recharged?
No. Do not charge primary cells.
Can LR48 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 LR48.
How does LR48 differ from PR48?
LR48 and PR48 have reference heights of 5.4 mm and 5.4 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.
