Not if they're hybrid NiMh's. That's the point, they won't be flat when you need them and you can use them as a spare set in your bag. Hybrios/Eneloops/Kodak pre-charged/etc hybrids are just better all round than any other NiMh especially in a K100D. The only time an ordinary high capacity NiMh will show any advantage is if you charge them up and use them the same day, you'll probably get 200 more shots under those circumstances. After a few days they will be on par and after a few weeks there's no contest.
