but didn't see where D's had that much functionality for the tools I have. I appreciate knowing they are the most scarce, but any ideas why?


I think zillions of people have flashlights that use D cells. The bummer about this is that the discharge curve of D cells doesn't lend itself well to flashlights since it drops off so fast. As a result, the light goes dim and yellow fast and people switch to a new set, even though they only used the batteries for a short time.
