Under these conditions, it's important to do a full discharge of the cells once in a while, or you will run into memory effect.
Oh I do. Last one was just two days ago.

Are you up for an 'Experiment'?
- You'll need something to use AFTER the C9000 finishes it's 100mA DISCHARGE since that's really a pulsed 1000mA DISCHARGE. An incandescent flashlight or a resistor will do - just don't discharge below 0.8VDC under load.
Great! :twothumbsYes. I am up for an experiment. This is the kind of 'fun' I wanted to have with otherwise near useless batteries...
It's not an EXACT science - they're *CRAP* cells already!...Only part I need to figure out is what I quoted...
...I probably do have the parts in shoeboxes, battery holder, old 1.5V ,bulbs, resistors and a multimeter... ...how often do I need to check loaded voltage and below what voltage do I need to get?
I don't have that one but do have a MH C-204F, I know its not as good as the 401, but when I bought that, the 401 wasn't made yet. I have done 5 cycles with bulb and re-charge on 204. I have made 'some' difference but not enough to make them useful yet. Most of the 8 still register HIGH !I could use the 401fs to recharge (spec is 200mA for AAA in slow mode) after a deep discharge if the c9000 wont accept them.
1. Done. They are now labeled N1-N4What would be interesting is to:
Looking forward to reading your results!
- Purchase a new set of AAA Eneloops
- Run a DISCHARGE @ 200mA on the C9000 and record the Capacities.
- Run a C9000 BREAK-IN @ 800mAh and record the measured Capacities for each cell.
- Run through your existing usage routine.
- Instead of CHARGING the cells in the 401FS, run a DISCHARGE @ 200mA on the C9000 and record the remaining Capacities.
- CHARGE the cells in the C9000 @ 400mA (0.5C)
- If the 'Percent of Capacity Remaining' as measured in Step #5 is greater than 10%
- Extend your usage routine correspondingly and go back to Step #5.
- Else, use this usage routine as your new 'norm'.
- Every 10th cycle, add a Deep Discharge after Step #5.
- Every 30th cycle, after the Deep Discharge, run a BREAK-IN @ 800mAh
Who has experimented on "fixing" HIGH cells ?
...
Has anyone else been experimenting with "fixing" HIGH batteries. What did you try ? and was it successful or not ?:candle:
Then I must have some real crappy cells then, cause I have several that display "HIGH".Cells have to be in really bad shape before the C9000 will refuse to charge them. I've never seen it, and I have run some really crap cells through it.
The ones that I have that the C9000 initially refuses to charge are AA & AAA nicads that have been abused all spring/summer/fall in solar landscape lights.Cells have to be in really bad shape before the C9000 will refuse to charge them. I've never seen it, and I have run some really crap cells through it.
Geez, what are you - some kind of 'Rechargeable NiCD/NiMH Cell' Newbie? :nana:...I've never seen it, and I have run some really crap cells through it.

So water ingress seems to have wrecked the AAA putting paid to the suggestions that it's dryness is the cause
I tried to drill a small hole in cell and add few drops of distilled water and close the cell by soldering and it works now excellent. Previously I got 2.3V now it is around 1.6V
Of couse it is just "project" and I won't use these cells because there is big chance they will leak but just to let you know it is possible
