I have a very nice cordless drill with a dead NiCAD Pack. The mfg
wants $50 for the 10 cell pack. Sub-Cs delivered mail order to
replace these would probaly run ~$30+. Based on what I see on the
capacity of the NiCad Sub Cs, the AA NiMH have surpassed them and are
about a buck a piece ). The only question is how much will the
(higher) battery ESR of the AAs work in a cordless drill. Any
thoughts on this?

You can find decent "new old stock" sub-C NiCds from time to time he
