Of course not; I walk a lot and use it all the time. When the cells in the camera go dead, I replace them with the charged spares I always carry. With "standard" cells, the spares were often near end-of-life when I installed them. With the Eneloops (even with their lower mA-Hr rating), I get several months of use even after carrying them around for some months.

Which is completely consistent with the fact the Eneloops gain that lower leakage by using a thicker membrane between the electrodes -- which naturally reduces the mA-Hr capacity.
All I wanted was to not run out of battery while on a several-hour walk, and then find that the "spares" were empty too. The Eneloops solved that problem completely.
