Probably a good idea to contact Sanyp, and ask them about this. But I read at the other forum about the same question, and he contacted Sanyo, and got aresponse that it's a known "error". But they are genuine.
We could just trust those words or double check with Sanyo.
Would be nice if there are some people who could make pictures of them as well, so we can compare.
Here in Japanwall batterieah have a Japanese text, so that makes it impossible to compare.
Discharge could be a little higher (at 500mA it’ll add 4 hours to each refresh cycle), but charge rate of 1A is OK (as long as your charger doesn’t overheats at those charge rates by itself, also warming cells up - like earlier BC-900’s did)
the C9000 displays the DISCHARGED capacity after the refresh&analyze operation rtfm ;). the charged capacity is always (much) less and does not depend (much) on the charge rate. For example, Eneloop AAA rated 800mAh nominal capacity, refresh&analyze:
C9000 discharge at -200mA, "capacity" shown as 834mAh (after the discharge process), then automatic rest, then
C9000 charge at +400mA, "capacity" shown as 834mAh (=value taken from above!). however, when you observe the capacity (during the charge process) it only goes up to 768mAh (at 1.47V, then displays "DONE"), before it jumps to the screening of the "834" value.
If your Eneloop AA (rated 2000mAh) is new and the C9000 refresh&analyze ends with 1637mAh, then it's the discharge capacity at -500mA. The C9000 puts in maybe 1496mAh during the +1000mA charge process, observe it!
btw imho 1600-1700mAh are a little on the low side. you should get at least 1900mAh (=worst Eneloop production batch); it's guaranteed by original Eneloops. i got way over 2000mAh for my AA's, and way over 800mAh for my AAA's. Eneloop rocks! (the original ones, at least.)
Sorry if I've missed the answer to this somewhere, but is it *safe* to leave NiMh batteries charging unattended, as opposed to li-ions? My i4 V2 and first set of eneloops have just arrived, and I don't have eleven hours to babysit them, which is what I believe they require :\
yes. that's what i claimed. and i am telling the truth, always :)
the values dont improve with refresh&analyze (if your Eneloop cells are of normal quality). with normal old NiMH’s maybe they could get better but with Eneloops they dont. The Eneloop values stay the same. they may get better though after repeated extensive cycling with infradeep underdischarge and ultrahigh overcharge. this way i was able to expand the capacity of my Eneloop AAA’s and the enhanced capacity (up to 884mAh) might explain why i get such record-breaking runtimes. this is again no ***t telling by me, trust me.
i would do the break in (~2.0 days duration!!!) right away, no more fooling around at this point thanks.
