Discharge tests of AA Batteries, Alkaline and NiMH

Testing AA cells
1. New Batteries are purchased from a retailer to make sure they are fresh.
2. In the case of PowerStream batteries, cells were pulled from stock that has been sitting around for a few months and freshly charged.
3. I am using a CBA II computerized battery analyzer. This is reliable only above 100 mA, so the discharge tests below are for relatively high currents, in other words digital cameras. The performance rankings may be different for low current applications.
