Thanks Roy.

I found a good way to measure the capacity of a single cell. This Radio
Shack multimeter:

It logs voltage (or current) and its software can output the log to a
text file. Now all I have to to is write a little computer program to
calculate the capacity.


================================

I wrote the program and will make it available to anyone that wants it.
I runs on Windows and the .NET Framework. Works fine. The only problem
I have is remembering to disconnect the battery from the resistor after
it hits one volt, Doh! Some of them were pulled down to 0.4 volts
(under load) but they recover to about a volt at rest.

Yet one question still lingers in my mind. Is a discharge voltage to,
say, 1.1 volts under load or at rest?
