Well, I went and did it--or so I thought: I bought 10 NiMH cells (4/5 A), I opened up my Type III (non-Apple) battery, looked at everything carefully, soldered the new cells together the same way the old ones were (including what are, apparently, thermal fuses), then soldered them to the wires (there was a small circuit board in the corner, rather than what others described as a thin circuit "sheet" across one end of the battery). After I rubber- banded it together, I put it into my external charger, and was thrilled to see it glow yellow. After a couple of hours, the light turned green. I measured the voltage, and it was about 14.5 (I don't remember precisely). So, I glued the case back together, put it into the Duo, and found--you guessed it--nothing! In other words, the Duo won't boot with the battery, and it won't keep running on it, either (if I boot on AC and then unplug it).
Can anyone give me a pointer as to what to try? The Duo doesn't quite act as if there's no battery--the "strip" that shows battery charge indicates between 2 and 3 bars--but it "flashes" to hide and then show the battery charge bars, which is just what it did with my old battery. (By the way: of the 10 cells in my old battery, 3 are at 1.2 V, and the other 7 show 0 V!) I am baffled: the battery clearly charges full, but the Duo doesn't see what it would like to see (presumably, on the other three contacts that I am not measuring). I don't think the case will tolerate another opening-closing cycle, but I'd like to know what to check for *before* I glue together the next one (I'm not about to waste 10 2150mAh NiMH cells, if I can help it).
