It can’t… I meant that I discharged a cell that had been charged by the I4. I used my battery/led analyzer (Any interest in a LED/Battery analyzer device?) to discharge the cell.
The cells that I got were in the 1.9V range (BTW, Panasonic data sheet says that these cell can be discharged to 2.5V under load).
I put one fresh out of the pack into the I4, it was recognized as a NiMH cell, charged for a few seconds, then all three lights came on… charge done. Removed and checked the cell. It was at 2.6V. I put the cell back into the I4 and it was then seen as a LiIon cell and spent the next several hours being charged. The I4 uses the cell voltage when you insert it to determine the cell type. It looks like 1.9V is low enough to cause it to think that it is a NiMh cell.
