Part 2 of the question is that the original power packs are NiCd. The OEM

that mean I can buy NiMH cells and simply swap those out for the existing
duff NiCd items? Or will there be electronickery inside the power packs
that I would need to contend with, and should therefore stick with NiCd?

IF the charger can cope with either, then yes you can swap one for the
other.

But consider the cost. Re celling may be as expensive as a new drill and
battery with LI ION ...

In general a sub C Nixx is between £2 and £5. 8 of then is already
£16-£40....

I have recently re-celled an ancient B & D electric screwdriver using
cells from batteriesplus and everything seems ok so far..
