Battery family hub

Watch battery cross-reference

Resolve maker numbers to canonical watch-cell families, then compare size, chemistry and W/SW drain designation.

Why cross-references need rules

A retailer list may place alkaline and silver-oxide options together because they fit the same space. This reference keeps exact aliases separate from conditional chemistry substitutions.

Start with the movement requirement

Use the exact code named by the watch or movement maker. If only an old cell is available, preserve every letter and suffix while searching.
