jospehcreveling, I was wondering about this for a while myself since I have "tons" of those as well. Of course we already know that there is more involved than just the output voltage. I always thought there has to be a bit more that we could test on those batteries. The only thing that I have come across in my studies about that so far is on here http://www.instructables.com/id/Li-Ion-Battery-capacity-tester-Lithium-power-test/ and yes it's an odd looking thing but the instructions are good and I think it may just be something worthwhile. Best of luck...
