AnswerLR41, AG3, L736, 192 are the supported exact aliases for one 7.9 × 3.6 mm alkaline button cell. No other family is treated as an automatic replacement.

Supported application context
- Devices whose battery compartment or manual specifies LR41 or a listed alias
Application context is limited to the scope stated in Energizer 192 Product Datasheet; it is not a device compatibility claim.
This alkaline family is often sold beside a same-size silver-oxide option. The shared envelope explains the confusion, but the chemistry and voltage profile prevent an unqualified direct-replacement claim.
LR41/AG3 shares its 7.9 × 3.6 mm envelope with SR41SW/384, SR41W/392 and PR41/312. Those alternatives cross chemistry, voltage or drain gates, so the AG3 alias stays confined to the alkaline family.
Commonly confused
What the code means
LR41 is the IEC-style alkaline button-cell identity. The other codes listed here are evidence-backed commercial or manufacturer aliases, not separate battery sizes.
Discharge and drain behaviour
Alkaline button cells have a more sloping discharge curve than same-size silver-oxide cells. Runtime and delivered voltage therefore depend strongly on load and the device cut-off.
Capacity context: Manufacturer-, load- and cut-off-specific; use the linked datasheet for a qualified figure.
Substitution guidance
Treat only the listed aliases as exact. Same-size silver-oxide families differ in chemistry, nominal voltage and discharge behaviour; use one only when current device or manufacturer guidance permits it.
