I got a pack of AAA's and seem to be a nice battery, I am very new to the whole nimh battery/charger stuff, (but learning more thanks to the guru's here) and therefore only have a couple ROV IC3 charger's which I have been told are fine for use with any nimh IC3 or not.
What I noticed so far using these with the IC3 is the runtime is still a little short of my IC3's which according to most thoughts on CPF is they need some cycles on them before reaching there capacity, so not real worried there, but a couple other thing's that I do have concerns on vis vi
the batt charger setup.

They come off the charger at or near 1.5 unlike my old energizer's and IC3's,
and drop quickly to 1.440-1.454, and lose a bit more over 5-7days, about the same as a IC3.(should be said my nimh "N" cells from TnC come off at or near 1.5 too)

Does anyone find this odd or is that about S.O.P. for a nimh and/or eneloops? My main concern is to not damage the new sanyo's.
I am dead broke from some medical bill's so I can't just hop into a Maha 9000 or other high end charger right now. VDG

from my understanding, and this quote from a dealer
"The "In-Cell Charge Control" system controls internal cell pressure, putting the battery in control instead of the recharger."
the IC3 charger can use battery pressure as a termination, that should be a VERY good system for determining if the battery is charged.
If they are not "IC3" type cells, then they will not gain the advantage of the pressure sence, and it will probably revert to terminating using a different method.

your voltage specs shown for a AAA are relative, AAAs will get higher in voltage than an AA in a charger . the high voltage is exisitng just because it was "hot off the charger" the lower voltages after "resting" are common.

I would say that you findings are normal. As you stated, the more the new cells are used they will gain some runtime.

I also used to use my R-VAC 15 min charger for other than that cells and found that when I used my MAHA charger the cells actually performed better, this may be an issue. But until you can get a better charger for non IC-3 cells it will do, hb.

Back in my NiCd Days 1.5 off the charger was not uncommon. Same with two 17 year old NiCds I just put back into service, hot off the charger they run my mini-mag the same brightness as primaries.
