Thanks for the clarification.

And, of course, as digital cameras are much heavier current comsumers, it
explains why alkalines can be so poor. I have seen earlier reports of
just 10 shots! The first NiMH I bought were 1300mAh, so the 2700 mAh now
available coupled with the reduction in camera consumption is a tremendous
