Overview: All Eneloop batteries 2005-2024

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.. ;)

The 1950 I got after break in is the highest I got, normal charges and discharges were around 1700 before break in.

Reading over at CPF it makes me wonder if those guys are talking out of their asses, nearly all of them claim they get around 2100 out of them.

I think typical is supposed to be 2000 and min 1900, I know its not a big deal though but its not what I expected.

Maybe Ill do another break in cycle on them sometime and see if it improves anything.

Kreisler, did you determine capacity in yours based on discharge numbers?

hi veer, i did some testing yes. charge rate is not a true factor in getting higher capacity reading from the C9000. you get (minimally!) higher capacity readings from the C9000 if the prior discharge was performed very slowly (either on the C9000 or with Moonlight mode of your light). that's also the reason why the break-in is the way it is: the break-in discharges at -0.1C afaik.

what are discharge numbers? you mean the number of cycles? i dont keep track of the latter anymore. years of use and abuse of Eneloops on cpf have shown that, as a rule of thumb, the cells are robust and "dont age", and that you can reset them to factory state with a break-in whenever you want to. in some cases, capacity can be increased. I, for example, did extensive overdischarging and overcharging of the cells, and capacity, according to C9000 readings, has increased since.

i check capacity mayber 1x per month. and it's not based on cycles. capacity remains constant. Eneloop wonder!!
