Same battery, different print
IEC codes (LR44, CR2032) dominate manuals and many EU/Asia packs.
US retail often leads with trade numbers (A76, 357, 377).
Online shops love AG13 / L1154 shorthand — still check the battery type.
Country ≠ battery type
A pack sold in the US is not a different voltage just because it says 357.
Use Check codes to map a printed label to the standard code.

Watch-trade numbers
Jewellers quote 377 / 364 — these map to silver-oxide families, not lithium CR batteries.
