Note that the capacity vs discharge curves don't go down that low for D
cells. You could try and extrapolate the curves, but that's only guessing.
When you get to figures this low you are talking 40000 hours+, the shelf
life of the battery.
If you want to use the full capacity of the battery then you need to have a
0.9V cutoff or slightly lower. 1.1V will be wasting a fair bit of the
capacity.
What is your application?

http://data.energizer.com/PDFs/E95.pdfCan't seem to locate any battery specs for Alkaline "D" cells. Tried
the Duracell and Raovac sites, but couldn't find much data for
standard cells. Read a few notes indicating the capacity of a standard
"D cell" is somewhere between 12 and 16 amp hours.
Anybody know what capacity to expect from a standard Alkaline "D cell"
at a continuous 0.5mA discharge rate until the voltage falls to 1.1
volts?
