As I mentioned in the other post, perhaps peeling off one of the wrappings might reveal some etching in the casing.

Another possibility is you shine a light at an angle to the wrapping and see if there might be some etching in the wrapping. Some times the lettering isn't "printed" but is laser etched, so it would be like pick-n-poke stencil style.

Look very similar to Panasonic cells from Tesla batteries.
