Probably a 1st year apprentice question, but can you substitute a NiCd battery of the same voltage/capacity in place of a NiMh without creating charging problems?
Sub C cell size varies a bit between makes, especially with welded tags, but 40-42mm end to end and 20-25mm dia is typical, so a 145 length stick of 3 is nothing magical.
I'd be surprised if you could not get cells in the right chemistry and size, and the same or higher capacity, welded up into a suitable stick, even if it is actually not a stock object.
Folk like Strikalite make a living out of putting together battery packs in obsolete sizes, (they have the spot welder and the heatshrink as well as a shed full of cells ) so if you do not fancy a misfit or rolling your own, they may be worth a call. (I have no connection, other than using them to make some rather special ones up for me at short notice a few years ago. They seem to be a modest outfit, and very helpful on the phone )
