Understanding SR1130 before replacement
Identify the actual battery
SR1130 is a documented Silver oxide / zinc primary cell with a nominal voltage of 1.55 V. Its reference diameter is 11.6 mm and its reference height is 3.05 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 SR1130SW, SR1130W with SR1130. 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.
A suffix such as W or SW describes a discharge/load variant. Preserve this requirement when choosing a replacement.

The following types share the same reference diameter as SR1130. Their height, chemistry or voltage may differ. They are comparisons, not approved substitutes:
What to check before replacing SR1130
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 SR1130. 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.

Other designations
These codes identify the same type family. Match the load variant, terminals and device requirements separately.
W and SW are different load variants. The combined 357/303 product does not make every 357 and 303 product interchangeable.
Documented brands
Brand presence comes from product documents or documented code mappings; current availability is not checked.
Product-specific observations
Capacity belongs to an individual product and test regime. It is not a universal value for this battery type.

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
SR1130SW SW / low drain · SR1130W W / high drain
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.

Common questions
What size is SR1130?
Ø 11.6 × 3.05 mm
Can SR1130 be recharged?
No. Do not charge primary cells.
Can SR1130 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 SR1130.
How does SR1130 differ from LR54?
SR1130 and LR54 have reference heights of 3.05 mm and 3.05 mm respectively, and nominal voltages of 1.55 V and 1.5 V. Their chemical systems are Silver oxide / zinc and Alkaline zinc / manganese dioxide. These comparisons do not establish a permitted replacement.
