On the left, the box that came with my original 41C (early 1980) and on the right, the box that came with my 41CX (Aug '83), straddling my latest '41, a V5 41CL, sporting a CCD ROM keyboard overlay (for Angel's OSX3 ROM, a permanent part of both of my 41CLs)

I did not recall the "Energizer" brand name went back that far; it appears it was coined between 80-83.

Seems I was both right and wrong about my box differing from Massimo's.

I also did a little bit of digging in that closet of mine and sadly I could not find the battery box for my 1981 41CV. So it appears it is gone!? I am pretty sure it was a Duracell one, but it could be that the shop put it together as they kind of put things back into the box when I bought it.

I did find the battery box for my 1986 41CX Halfnut though, it looks the same as your second one.
