You would never actually get all of the MAh out of the Ds and into the AAs. Large amounts would be dissipated by heat. Also, rechargable batteries need more wattage than that to charge efficiently. Ultimately, I suspect 4 D cells would be able to charge 2 AA cells about 1/2 times, but it could be used as a pocket warmer in the mean time.

um... 10 sets of AA's actually - it would take up less space and would weigh less. That said, I agree Naivetek is probably a big hint.

Guess what? You can actually do this by taping D batteries together with any lower size.
