One way to buy cheap eneloops that you know aren't fake is to buy duraloops .

probably one of the best things the flea markets sell is cheap batteries

got great deals on lithium as well..To some people a battery is just a battery .

last deal I bought awas all packages were a buck .the obvious deals are on the 12 packs of AA or AAA's but cr123's or 4 packs of nimh  or lithium can sneak past people who don't know or care .

I love the Akihabara.

Here are some shots of the ones I got, I don't know if they are fake or not. 

I tried to get pics of the stamp on the side but it was impossible with my phone, they say "1  1  06IP"

On the bottom they say www.ebattery.co.kr, it shows a lot of Sanyo products and it says they are a Sanyo partner.

Sorry about the crap photos, the auto focus keeps zooming in and out and making it really hard to take clear pictures. 

 

Do you think they are real?

They look identical to the ones I got from a reputable German seller. 

The space in "... FIRE,NOR ..." is missing on mine as well.

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.

Just did a discharge, 1523 and 1532 out of the packets.

Doing refresh analyse now, charging at 1000mAh and discharging at 500mAh. 

I think that's safe/ok/good from what I read but people argue over Sanyo's and Powerex's recomended rates.

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)

Thanks Shadowww, it just finished doing a refresh while I was asleep. It only put around 1600-1700mAh in to them as far as I could tell. 

Doing another discharge now, hoping for around 2000mah but I don't know if I'll get it.

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 :\

Thanks but I don't understand it all, its still the first time I used it. 

So at the end of the refresh my batteries were showing the discharge capacity? 

That does seem pretty low, on the packet it said "Typical 2000mAh" and "Min 1900mAh" 

Maybe if they don't show a improvement after this discharge I should try and use the break in function?

Yep, break-in is always good. Make sure you fully discharge them before doing break-in, though.

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

yes. that's what i claimed. and i am telling the truth, always Smile

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.

After discharge: 1761mAh and 1759mAh

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

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.

@ 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.

http://www.ebay.com.au/itm/290699229222

 

@ 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 Smile

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

http://www.dinodirect.com/4-x-SANYO-AA-2000mAh-Ni-MH-Rechargeable-Battery.html?d=23068523

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.

ChibiM, how much did you get them for?

I got the AAA`s for 1480 yen.. which is cheaper than any online store in Japan. Converted, that will be about $18..
(In the US they tend to have much better deals, like the deals at Costo.)

The AA`s I got for 1750 yen.. that would be around $21..

Thats the cheapest I could find in store. For many online stores they charge shipping, so that would only add up.

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.

I like: walks on the beach, sushi and things that are paisley.

Very nice topic Smilegreat 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 Frown

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
