They already did. :)
From ChibiM's website:
Depends on the charging rate. Good NiMH chargers do not terminate based on voltage level, but rather via the DeltaV or DeltaT methods, which look for a voltage drop or temperature rise, respectively, to determine when the fully charged state is reached.

When do you take your voltage readings? You need to give the batteries a few hours or a day to reach their resting voltage level, check the voltages again then.
I have three of the BQ-CC17 chargers. They normally terminate at voltage levels between 1.50v and 1.55v. It does depend on when the charger sees the delta-V drop, but it’s usually in that range. Very quickly, however, the cells will fall to about 1.45v, then about 1.40v by the next day.
So, I suspect that he’s measuring the voltage a few minutes after termination in the BQ-CC17 case. But even if not, 1.465v is almost full.
I think the SkyRC may be over-charging those Eneloops, if it’s not terminating until 1.65v. That sounds too high, from what I’ve experienced with a variety of smart chargers.
Maybe ask the Eneloop tech what is the max voltage cells should be charged to, if delta-V isn’t used or is missed.
Pablo, Walkintothelight, if I remember well, I took the voltage readings the next day. Thanks for clearing that up for me!
thats nice. Hope they are not available only in Japan…
Thanks for doing this.
I’m interested in how the sales of NiMH cells have changed the past few years.
Most electronics have moved towards li-ion, so I’d assume they would have gone down, but that’d just be my guess.
@sirius, yes, there are already some new eneloop editions :) and Japan didnt have any special editions since 2015......
@klrman: the SKY rc 3000 has that only as Max. So they will probably stop way below that Voltage, because the detection of -dv cut off will be the reason to stop the charge. Probably you measure the 1.46V directly after taking them off the charger? Check out HKJ review about the details.
@Pablo, yes, thanks!
@Pabo, yep, depends on when you do the voltage reading.
@Walkintothelight: yep, depends on when you check the voltage.
@Ryansoh3: good point.. noted that down.
Thanks for all the interesting questions!
best

Never charged the eneloops with the SkyRC MC3000 as of yet, just went through the menu until I got to Eneloop and scrolled down, but I didn't know how it works and just thought it was going to terminate at 1.65V without knowing about the the dv cut off, thanks for explaining that. Next time I charge the batteries with the BQ-CC17, I'll Iook at the voltage right after I pull them then a day later to make sure I am posting the correct voltage.
Sure! The voltage under load is different from the voltage taken directly off the charger. So the 1.65 is Voltage under load. Even if you'd take them off the charger and measure the Voltage within 10 seconds after taken them off, you wouldnt see 1.65, but less. They quickly drop in Voltage when they are taken off the charge :)
Get your last questions in today!
What is the most unusual/crazy test that he has seen performed with eneloops?
Why does BLF like Japanese robot girls so much?
Can ChibiM have free samples to share with BLF members who have asked questions? That’s eneloop samples, not robot girls, although… if robot girls are primarily designed for cooking and cleaning I am sure my wife would let me have one :innocent:
one more question: how do eneloop ages when they are not in use?? Are they good for 10-20 years or even more?
When is going to be the meet up with that eneloop guy??
Following
They’re good for at least 12 years. I have some Eneloops from 2006, and I’m going to run a capacity test on 8 of them this weekend. (I’ll post when I get the results.) Based on how they still perform, they’re still very good cells. Internal resistance is definitely higher than new Eneloops (based on the IR measurement from chargers), but it’s still low enough to use them in high-power lights. But I mainly just use them for radios and stuff like that, now.
Oh, and Japanese robot girls rule!
That is official claim from sanyo/panasonic or it is the conclusion you have found taking into account your eneloops??
@mapache: Good question, will ask him about the robot girls! You never know, but you can join the eneloop101 facebook group where I will be doing a giveaway soon. (when we reach 100 likes).. Have done enough of them here :D
@fran82: that question I already have on the list! great question.. definitely interested to know. I will meet him/them tomorrow afternoon.
Have fun ChibiM. I hope its what you expect and more. 
I am looking forward to it! Just have no idea how much time I have with him/them. I literally have about 60 question.. LOL...
He might think to himself....oh boy oh boy, what did I get myself into?... that Dutchmen is crazier than I expected! (I will just pretend to not understand him)
I think you are lucky to have the chance to interview that person…
Good luck enjoy and let us know the answers!
Thanks! I will!
