Conventions

« Values: Each size is the envelope of the makers' datasheets, one lineage per maker. Disagreeing limits take the widest band the makers allow.

« Can and cap: A cylinder d x h on the positive face; the negative cap step d_cap x h_cap only where both reach L1.

« Negative edge radius (LO): The can's outer edge at the negative face is rounded to r_neg, Energizer's reference radius, where a sheet gives one: a single lineage, so labelled LO.

« Edges and marking: House style, illustrative: the can crimped over a black gasket around the negative cap, the CommunityCAD logo engraved in the positive face.
