I think the originals would have been a set of AAAs shrink-wrapped in a package, but like I said, drop TE an email - they might still have them, and they might not be all that expensive. Certainly, the bits they sent me were extremely reasonable.

I also have a 303 'scope calibrator here, and that has a similar deal, but the cells are larger than AAA - I think they're C types, but I haven't had a chance to properly investigate and restore it yet.
