If you can’t be bothered to read a document then I don’t think you can have any
valid opinion or comment on it.

There are quite a few. Mouser lists 278 that claim NiMh capability. All but 9

Probably because of the characteristic of their discharge in conjunction
with the heating coil.

I can't speak with any authority on the NiMH vs. NiCd substitution,
except that I've replaced them on low-draw devices and used the same
charger. After 20 years of doing this, I can't claim to have destroyed
any NiMH, though I can certainly appreciate the self-limiting of
overcharge on NiCd

Hi Jim, Maybe this is specific to europe but NiCds are hard to come by here,
they are prohibited since 2008 And even more prohibited since 2017 ( they also
exclude medical equipment ) I used to source them in ex-ussr countries but even
there they are hard to come by nowadays, quite expensive,
