Second-source check pending Primary batteryReviewed:
Reference dimensions are not universal manufacturing tolerances. Check the actual cell and holder.
The type status describes documentary checks of core specifications, not every fact or suitability for a device.
Understanding AAAA before replacement
Identify the actual battery
AAAA is a documented Alkaline zinc / manganese dioxide primary cell with a nominal voltage of 1.5 V. Its reference diameter is 8.3 mm and its reference height is 42.5 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 LR8D425, LR61, E96, MN2500 with AAAA. 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
No other type with this reference diameter is currently included in the catalogue. This does not prove that other sizes or alternatives do not exist.
What to check before replacing AAAA
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 AAAA. A missing compatibility relation means “not assessed,” not “compatible.”
How reliable are these specifications?
The principal characteristics are currently supported by one primary source. A full independent second-source comparison is still pending.

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
LR8D425 · LR61 · E96 · MN2500
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
AAAA: Only one manufacturer or an insufficient independent source supports the cited measurements. Published technical records: Energizer E96 (dimensions); Duracell AAAA (designation only); AAA / LR03 excluded. Device-level compatibility must be verified separately.

Common questions
What size is AAAA?
Ø 8.3 × 42.5 mm
Can AAAA be recharged?
No. Do not charge primary cells.
Can AAAA 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 AAAA.
