I could, but two reasons for not doing it:Couldn't you put in modern NiMH such as Eneloop? I have a 1970's TI56 which had two NiCd AA cells and has had Eneloops in it for a year or so.
- I don't trust the old NiCd charging mechanism to properly/safely charge NiMH batteries.
- To use a NiMH charger, I would have to remove the batteries from the pack to charge them. And I would rather not stress the case, and risk cracking it, since the pack was not designed to remove the batteries.
