Understanding PR44 before replacement
Identify the actual battery
PR44 is a documented Zinc–air primary cell with a nominal voltage of 1.4 V. Its reference diameter is 11.6 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 675, PR675, P675, 7003ZD with PR44. 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 PR44. Their height, chemistry or voltage may differ. They are comparisons, not approved substitutes:
What to check before replacing PR44
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 PR44. 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
675 · PR675 · P675 · 7003ZD
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
PR44: Published nominal voltages differ among manufacturers; this is not proof of device incompatibility. Published technical records: Panasonic / Energizer 1.4 V; power one p675 1.45 V (size 675). Device-level compatibility must be verified separately.

Common questions
What size is PR44?
Ø 11.6 × 5.4 mm
Can PR44 be recharged?
No. Do not charge primary cells.
Can PR44 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 PR44.
How does PR44 differ from LR44?
PR44 and LR44 have reference heights of 5.4 mm and 5.4 mm respectively, and nominal voltages of 1.4 V and 1.5 V. Their chemical systems are Zinc–air and Alkaline zinc / manganese dioxide. These comparisons do not establish a permitted replacement.
