My experience with NiMH, also relates to the total time since the batteries were charged. During my last trip to Denali, I would get around 1000 shots on a battery charge. Those shots were taken in a 2 to 3 day span of time. I can put the same batteries, freshly charged, in my D, let it sit for several weeks & only get a few hundred shots til they need recharge. This experience seems pretty logical to me but I don't see anyone taking this into account when they relate battery life experiences.
