Hey all,

I want to compare the Eneloops that I got from Dealextreme with the ones I
got from Dell to see if the DX ones are genuine Eneloops (there are very
slight physical differences, but the performance never led me to doubt thei=
r
authenticity).

I figured a simple way to profile them was to measure under-load voltages
while draining the cells with some resistors at around 500 mA. But this
would mean current drain would decrease as the battery voltage decreases.

1. Would this still be a reasonable way to profile the batteries? Can I
still mathematically compute the battery capacity using the graph?

Another option would be to make a simple constant current source circuit
that would ensure a constant current drain on the batteries.

2. Can anyone recommend circuits for making one of these?
