Question: I tried charging NiMH batteries in my scanner & the batteries appear to be getting very hot/expanding/etc.
Answer: NiMH batteries require a different charging circuit from NiCd. You should never charge NiMH batteries in any device or charger unless
it clearly specifies that it will charge NiMH batteries.
