Recently purchased the MH-C9000 and have been using it successfully in break-in mode and refresh-analyze on new 2100 mAh Immedions and older, low use 2700 mAh PowerEx Cells (Camera flash).
I have also "successfully" gotten the "HIGH" reading from some old Lenmar cells.
I have some well used 2100 mAh PowerEx cells that have been charged in the Maha MH-C401FS (individual cell charging) for a couple years. They still seem to take a charge in that charger. In the MH-C9000, 3 out of 4 of them behave oddly.
When I insert one cell at a time in any slot of the C9000 it resets shortly after getting a cell reading. It does not matter whether I've selected a mode or just leave it sitting on the mode selection - as soon as it reads 0 mAh, it resets (entire display goes blank, backlight goes off and then starts up again).
Sometimes if I leave the cell in for over 20 or so resets, the display finally reads "HIGH"
If a cell in the charger is successfully charging, then when one of these cells cycles around, it acts like I haven't set the charge mode yet.
I searched the manual and online to try to understand if this is a known or expected behavior - but can't find anything.
My questions are:
*) Has anyone else seen this behavior?
*) If so, is it a designed-in behavior since the "HIGH" eventually registers?
*) Or is my unit defective?
*) Why do these batteries appear to take a charge on the C401FS? Maybe because I don't get cell stats back from that charger, I don't notice because good and bad batteries get mixed?
Thanks much,
D.
