Found my source. Duracell Alkaline-Manganese Dioxide tech bulletin. http://www1.duracell.com/oem/Pdf/others/ATB-full.pdf Rated (maybe over-rated?) capacity of the Duracell MN1500 (AA) cell is 2.850 AH. >Alkaline batteries don't like high current draws.

Useful information. From Energizer's Application manual, the lithium cells would seem to be better suited to this application. The shelf life, temperature characteristics, and high discharge capability look good, too. I'll have to check local stores for availability. Just need to find an 8-cell flat-pack battery holder.
