Overview: All Eneloop batteries 2005-2024

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.

Also I guess they could be fake, I'm not sure. Ill post results after this discharge and possibly after a break in.

Shadowww: "Both NiMH and Li-Ion are safe to leave unattended if a) batteries are of good quality b) charger is of good quality."

Thanks

After discharge: 1761mAh and 1759mAh

I'll start the break in mode now, hopefully that will fix them.

BTW, when was the date when gen III Eneloops should be on the markets?

They already are.

But only in Japan. :(

Aaahhh, right.

Might just get then some of those 2nd gen ones. Gifted away 4pcs of 1st gen with a digital camera so need to stock-up.

After the first 16 hour charge and discharge: 1973mAh and 1976mAh

Its on the rest cycle now.

Good results.

@ Cheap Thrills

I found some third gen ones on eBay but its not cheap, its about the same as you would pay in the shops here for second gens.

@ kreisler

Should I discharge again after the final 16 hour charge to see what capacity I will get?

And if I charge it normally after that it should be around the same from now?

I don't know that they will get much better. About the highest I've ever read is 2050. But none of them were below 1900. Your latest readings are right around the average for mine.

the highest i got was 2063mAh at my very first break-in (and i havent done any other break-in since!) and when you do refresh&analyze the number will stay about the same; typically it's a little less because you discharge with higher rates but sometimes it's higher lol.

what's the manufacture date of yours? (it's printed *on* the cell wrapper!!)

i would give them some good use from now on (flashlights!!), e.g. in the high-amperage draining cletus P1A or P2A. Eneloops seem to like it when they get some good use (high discharge rates, high recharge rates, frequent use), i think it's called conditioning. And then after 10 cycles do a refresh&analyze again.

take the following table as reference:

In other words ezarc, YES, please do a refresh&analyze right after you're done with the break-in :)

1949mAh and 1950mAh

I just got 4 more in the mail too.

Not to mean to hijack this thread, but are these genuine Eneloops?

Its affil link. I have 10$ gift card from DD and this would seem like a tempting deal on getting 4 Eneloops for less than 6$. Even if thy are only 1st gen one.
What do you think?

EDIT: Judging by product pictures its 2nd gen. I guess Ill have to ask them to be sure.

Looking just at the pics, they are 2nd gen.

Real? I think nobody knows. Unless someone actually bought them, who can say more. You might have to wait 6 weeks, and receive a gift card when they are fake.

Yeah, so far it has been flawless with DD for me, so Im not affraid of receiving fake ones and then losing my money, BUT still, they should be genuine if sold as such.

Will see what they answer and then order some.

Thanks.

I can get 2nd gen eneloops locally for about $10 per set of four. Seeing prices in this thread now I wonder if they are fakes.

Very nice topic :) great job ChibiM.

I read somewhere that new Disney-white (so-called: LoveLove) edition are made only in the AAA format, is that true?

(black&red = Mickey&Minnie) are available in AA and also AAA format!

*Oooo, if I only live in Japan


Here is a nice page with 3D overview of disney series

After running my eneloops flat in my PA40, I did a slow charge at 600mA and discharge at 500mA

Not so good results this time:

1896, 1890, 1896, 1902

ezarc, not the charge speed (transfer rate) is important ---it doesnt matter very much if you charge fast or very slow; the transferred charge will be the same!--- but the discharge speed (transfer rate). one gets more (continuous) charge out of a cell if the cell is discharged very slowly. (this can also be seen from doing maths on the parametric discharge graphs of Liion cells).

your numbers sound sound .. because -0.5A is 0.25C, which is ..etc.. ;)
