I also posted basically this in another thread - but thought it may be of interest here -
I just got a Maha C9000 (code: 0H0FA) - so this is "novice" usage -
I ran a discharge test on 3 different sets of my LSDs to compare.
These were perhaps my least used sets -
which have had what I would term my "ignorant" usage -
ie: I just charge them in a cheapo smart charger (Soshine SC-C3 Intelligent Rapid Charger) and use -
recharge when necessary - usually after they get depleted (shutdown) in equipment.
But like I said these were my least used - 1 to 3 cycles may be....
I topped up charged each set then left on charger for 1 hour (trickle charged? I know, maybe I should have left them on for 2 hours but I was impatient - and those batteries were all relatively recently fully charged on my cheapo charger or the Maha C9000 anyway) -
turned charger off then started discharge at 0.2C (for all these = 400mA)
... Kodak Pre-Charged ...... eneloop ................... DuraLoop ................. Kodak P-C (1-4)
1) 1951 mAh (322min) .... 1878 mAh (311min) .... 1867 mAh (308min) .... 1966 mAh (325min)
2) 1961 mAh (326min) .... 1867 mAh (311min) .... 1858 mAh (308min) .... 1942 mAh (324min)
3) 1994 mAh (329min) .... 1900 mAh (315min) .... 1872 mAh (309min) .... 1993 mAh (330min)
4) 1944 mAh (323min) .... 1861 mAh (310min) .... 1868 mAh (310min) .... 1907 mAh (318min)
EDIT to ADD - I just finished another discharge of another set of Kodak Pre-Charged - these have had more "abusive" usage - as this is the set that I use for my flashlight reviews - so they often get top-up charges and rarey get fully discharged in normal usage - I bought these back on June/21/2007 so were first charged on my cheapo jWin charger - relatively "smart" using -dV detection, claimed output current - 900mA, but only charged in pairs - then after mid-Feb/2008 I used the Soshine SC-C3 Intelligent Rapid Charger and only charged 1 to 2 of these at a time taking advantage of the higher 1050mA charge current.
This time I did a top-up charge on the Maha C9000 and left the batteries on the charger (trickle charged?) for over 2 hours - then turned the charger off and back on for the discharge at ~ 0.2C (=400mA)
Once again, but basing on only 4 samplings - it would appear that my charger's slot #3 seemed to show the highest capacity.
The DuraLoops (Duracell Pre-Charged made in Japan with white tops) may have had a slight "advantage" I actually ran a refresh & analyze on those - but forgot to look in the 2 hour window and missed what capacity they read
It would appear on this sampling of only 3 sets, that slot (3) on my Maha C9000 may read higher than the other slots?
Also please see summary post #57 from eneloop vs. Kodak Pre-Charged Voltage Maintenance.
