Why not use lithium AA? Duracell aklaleaks are the worse, in my experience. At least if the alkalines do leak, they're in a carrier away from the MB.

They’re using rechargeable NiMh, not alkalines. I would have used the older Eneloops or current Fujitsus, but maybe rechargeable Duracells have better quality than their alkalines.

The NiMH Duracells are very high quality (at least according to Project Farm).
