Being unable to find any good battery life data on the Web, I decided to take the matter into my own hands and test various batteries myself.
I constructed a battery tester using an AA battery holder and a 5 ohm 1/2 watt resistor. This arrangement draws 300 ma @ 1.5V. I then ran each battery until its voltage dropped to 1V. This is a very conservative range. The included chart illustrates the results.
The 3 batteries I have tested so far are all non-rechargeable:
Radio Shack Alkaline 1629 maH
Duracell Alkaline 1858 maH
Energizer e2 Lithium 3100 maH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1
Note: maH is calculated from the area under the curve.
I am now going to test a few Metals and see how they do.
