Understanding LR44 before replacement

Identify the actual battery

LR44 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 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 1166A, A76, AG13 with LR44. 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 LR44. Their height, chemistry or voltage may differ. They are comparisons, not approved substitutes:

  • PR44 — PR44: 5.4 mm high, 1.4 V; Zinc–air.
  • SR44 — SR44: 5.4 mm high, 1.55 V; Silver oxide / zinc.
  • LR43 — LR43: 4.2 mm high, 1.5 V; Alkaline zinc / manganese dioxide.

Commonly confused markings and sizes

LR44 and SR44 share 11.6 × 5.4 mm reference dimensions, but LR44 is an alkaline 1.5 V type and SR44 is a silver-oxide 1.55 V type. The dataset records conditions for substitution in each direction rather than a universal equivalence.

What to check before replacing LR44

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 LR44. 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.

These markings resolve to this type in documented sources. The exact variant and device requirements still matter.

Conditional replacement: review requirements

Required LR44 → candidate SR44 — SR44

Conditional only: chemistry and voltage differ. Check the device instructions and every condition below.

SR44 has 1.55 V instead of 1.5 V. The device must accept the chemistry, voltage and load profile.

  • Use a holder for the correct bare-cell size.
  • Observe the correct polarity.
  • The device manufacturer must accept the candidate chemistry and voltage.
  • Match the required load profile, including W/SW.
  • Do not use these primary cells in a charging circuit.

Known obstacles to direct replacement

Required LR44 → candidate LR54 — LR54

Reference dimensions differ. A particular holder has not been evaluated; no direct replacement is established.

  • Check the holder dimensions.

Common questions

What size is LR44?

Ø 11.6 × 5.4 mm

Can LR44 be recharged?

No. Do not charge primary cells.

Can LR44 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 LR44.

How does LR44 differ from PR44?

LR44 and PR44 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.
