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 MT920 before replacement
Documented battery characteristics
MT920: Rechargeable lithium manganese titanium, 1.5 V, Ø 9.5 × 2 mm. These are reference battery dimensions, not a verified device fit. Cell and battery pack shapes, contact layout and charging requirements can differ.
Rechargeability and product-specific charging specifications do not establish suitability for a charging circuit. Do not replace primary cells with rechargeable cells based on size or voltage.

Replacement limits
Device compatibility has not been verified. Dimensions alone do not prove that a battery fits or works.
Rechargeable does not mean interchangeable. Charging circuitry, terminal shape and device compatibility have not been verified. Never charge a primary cell.
Replacement evidence by category
Other markings of this technical type
No additional documented designation.
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
MT920: The device charging circuit, terminal geometry and complete capacity-test conditions have not been verified for this exact product. Do not assume charger compatibility. Published technical records: MT920. Device-level compatibility must be verified separately.

Common questions
What size is MT920?
Ø 9.5 × 2 mm
Can MT920 be recharged?
This is a rechargeable cell, but charging is permitted only according to the manufacturer specification for the exact product and an approved device charging circuit. The database does not verify charger or device compatibility. Never charge a primary cell.
Can MT920 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 MT920.
