    aa Battery's Race To 0.8v How Much Interest Is There?

    Here is the deal. The other day I started what I would call a real world aa Alkaline Only battery drain test. The goal was to use a FIXED known load wired into a 1 slot aa battery holder with leads. I used a 10watt 4.7ohm resistor for the load for each. I checked the voltages out of the pack...
