Conventions
« Values: Each size is the envelope of the makers' datasheets, one lineage per maker. Disagreeing limits take the widest band the makers allow; a limit only one maker states is left open and the other bound is modeled as a single limit.
« Body and positive contact: A cylinder d from the negative end to the shoulder at h - h_pos, then the positive contact d_pos x h_pos on the axis, its top at h.
« Negative end: Flush, except where the datasheets give both limits of the recess e_neg (A23, CR123A): then a pocket d_neg wide, e_neg deep at its midpoint, its floor the contact face.
« Edges and marking: House style, illustrative: steel can with a rolled shoulder and raised negative disc, label wrap with a seam and the CommunityCAD logo, black insulating ring. No vent; chemistry isn't part of the geometry. Drawings show the sourced envelope.
