Since AT&T's model has the thicker NCF 1650mah battery by default I'm thinking that the Korean NFC 2000mah package may fit since that is probably what the AT&T GSII build may likely be based on since the AT&T version has NFC and is a mm or so different in size vs the international version, similar to the Korean SGSII version and how the international version can't handle the Korean kit (the 2000mah NFC battery fits, the back doesn't).
What would be interesting to know is if the international battery kit back fits the Korean GSII's since we know the Korean battery kit back does not fit the international GSII, and from what I've seen on the internet the AT&T version can not use the international kit (probably due to the back but the battery may still fit).
If anything I hope its just the back of the AT&T GSII that is incompatible with the international GSII cause if the battery and the back is different in size then I'll be really pissed cause that would mean that AT&T has a totally different size from all the rest of the GSII's which could make buying accessories really slim picking, one of the main reasons why I held out over the AT&T variant over the Sprint version was the similarities with the international version which means more accessories to choose from. So HOPEFULLY the Korean kit works.
Another option is to look at the batteries for the Indian version of the GSII since it supposedly has NFC as well but I have not seen anything on it. And of course we could just wait for AT&T and Samsung bring out the 2000mah battery kit for the AT&T GSII but I'd be surprised if they have any plans on doing that anytime soon if at all since Samsung will be busy with the Nexus and AT&T will be busy with their upcoming QHD and HD phones.
It's just a hunch but I went and ordered the Korean NFC 2000mah battery kit from exportprive for $35 USD (plus $20 USD "express" shipping) over the weekend along with a couple of those charger stands ($13 USD each) and I guess they will ship it soon so I'll be the guinea pig for testing the Korean battery kit and the AT&T GSII, wish me luck !
That is a lot of typing for a battery ha ha..jk
Look forward to seeing if this works if so I'll follow suit.
From reading the general SGSII 2000 mAh thread, I believe as long as it's "NFC" it will fit our phone.
After all that hassle, it will suck if the 2000mAh batteries have less capacity than the 1650mAh batteries due to Samsung's standards over cheap battery mfrs...

Reports so far from people using the 2000mah batteries on the international GSII are calling it a 20%+ gain in battery life along with better cooling due to different back and overall good looks without much of an addition in thickness with the phone being around the thickness of the Captivate after the battery and back are installed. If it works I think it will be a great addition to an already great phone.
Ah, just got a response from exportprive that explains the situation:
Hi,
The EB-K1A2EBSG is the Korean version of the EB-K1A2EBEGSTD, and was supposed to be compatible with all Galaxy S 2 versions. However, it turns out that only the back plate is incompatible, and only fits the Korean Galaxy S 2. In fact, the 3 top left grooves (with the outside of the back plate facing you) are aligned differently by just a few millimeters, which bends the case when trying to insert it in your device. We apologize for any inconvenience, and offer you the following alternatives to solve this problem:
1. A refund for this item (or a credit of the same amount).
2. A partial refund of $6 USD per item if you wish to keep it as an extended battery (which is an NFC version).
We are open to any other suggestions. Please let us know what you wish to do.

I wonder how much trouble it would be to get an extended back for the AT&T version to fit this back? Seeing how the 2000mah NFC batteries aren't as easy to come by as the even more hard to come by regular international 2000mah batteries.
I would hate for someone to be a guinea pig but I'm going to wait till someone tries it on the US version.
I await to see how this plays out. I would love to have the larger battery

I cancelled my order, the battery does fit but then the replacement back to go with the battery doesn't. Hopefully Samsung will put this kit out for the AT&T version .

I wonder if there's a non-Samsung door that will work.
I got this battery with a dock charger and it works fine but when I plug it in to anything (computer/usb or power/usb) it freezes the phone and makes it cycle the battery charging/phone off symbol while the battery(?) makes a very quiet clicky sound. Not good. So I started charging it on the dock (came with a spare battery charging slot) and carrying it as an extra. It works fine, just don't charge your precious AT&T Galaxy S2 with it.
I did the shot at this angle so you could see the contacts, I saw some mention of it. My bad on the upside-down hah.
All questions concerning an AT&T version seem to be ignored in the international version thread...has anyone found one that fits our version??
The 2000 mAh battery for the international Galaxy S 2 should work on the AT&T version since the back appears identical.
the backs appear identical, however the international version is not NFC capable and therefore that battery will not be the same. but i agree that the I9100 thread seems to ignore any comments about the I777. wth.
I just bought the 2000 mah batter from Ebay and it has the NFC label on it. Of course, I have the international version and it doesn't fit. For those that have the US version, PM me if you'd like to buy it. I'm in the SF Bay Area, CA.

I just posted about the extended battery I recieved yesterday. It is a 2600MAH battery from a company called TruCell. I took a risk because they were the only company I found on the web selling a battery specifically for the AT&T model. Funny on Ebay it said for the AT&T Samsung Galaxy S2 but whe I look at the battery it says for the I9100. In any case the battery and the case fits perfectly. Phone is heavy as all get out but If It gives me an extra 4 to 5 hours of heavy use then I am perfectly fine with it.
what did that monster cost you???

Amazon Link: http://www.amazon.com/Hyperion-Sams...JE8K/ref=sr_1_1?ie=UTF8&qid=1319900790&sr=8-1
Includes: 2 x 1800mAh Battery and 1 x Universal Wall Dock Charger
I was tired of having to charge my battery, and wanted a backup battery to carry around with my phone in case of an emergency (or I want to game...a lot). Therefore, I purchased Hyperion's Samsung Galaxy S II extended battery w/ a travel charger.
So far, I've been very happy with my purchase. I have yet to ever have any battery problems of any sort. When my battery finally runs dead - I just take it out, and put the new one. BAM! 100% battery again! The dead battery then goes on the charger, and the battery that was on the charger before (but is now done charging), goes in my pocket!
PROS: Two 1800mAh batteries provide a bit more capacity than stock. Great to have another battery with you - while your 3rd battery is charging (One battery in device, one in your pocket, and one charging on the wall charger!).
CONS: Cannot charge device with one of the batteries. You will go into a boot loop (AT&T only). This isn't a problem for me, though. I've only used the wall charger to charge my device since I got it. Oh, and I use Kies Air to transfer pictures, music, etc.
Q&A:
Question: Is there a "boot loop" with these batteries?
Answer: Yes, on AT&T variants at least. I do not find this a problem - I use the wall charger for charging.
Question: Are these batteries as good as the stock battery?
Answer: They do have a bit more capacity, but seem to be about the same. Maybe a bit better than stock - but not by much! Still, stock has a great battery life, and so do these!
Question: How does the Wall charger work?
Answer: You plug it into your wall, and place the dead battery which you'd like to charge into it. A RED light means charging, and BLUE means finished.
Question: Is there an extra USB port for charging on the wall charger?
Answer: Yes. This means you can charge your device (stock battery) and another battery at the same time.
Thank you for reading my review on this great product!

Sean,
I noticed your feedback and thought I would let you know that the reason you are having the issues you are having is as I can tell by what you stated in your feedback you have the wrong phone for these batteries you bought. You purchased batteries listed/advertised for the i9100 ( galaxy SII, the international version ) and have attempted to use them in the ATT SII i777. I am willing to help if you would like with either a refund or a replacement ( we have about 6-7 days until the i777 2x battery and charger set launches ). Please let me know which you would prefer, and I am sorry you have had to deal with choosing the wrong batteries and hope we are able to help you in this matter!

Yes please let us know how to get in contact with them as I too have bought this version for my att sgs2 and they dont seem to last as long as my regular battery...would like to get them replaced.
Oooh I hope the i777 version don't have boot loop. I'll be all over that.
I'm assuming that the stock battery charges just fine in this wall charger as well?
2nd day of owning the hyperion battery... it appeared to drain fast in the first cycle (i lost 7% at 80 minutes idle... on stock, i would lose 1%-2%). im draining the battery again for the 2nd cycle... i hope it improves, because it's certainly not as good as the OEM battery for me. i guess 6ish percent per hour for idle isn't too bad... should last me a whole day, but barely.
did you guys who reviewed it well have to go through multiple cycles?

For $45 they better plan on coming by 2x a week to clean the lime-stain ring from the toilet bowl. For a "china-model" battery that's absurdly high.
But I am interested to see when this one goes to market if they've figured out how to produce a battery that'll charge inside the phone.
Not sure why ATT pisses off their customers by having Samsung spec a phone which requires customers to purchase batteries and phone parts direct from ATT. So annoying.
Anyone get it yet? I might order one on payday and report back unless someone beats me to it.

Bump.
Anyone using it? I'm considering getting it if anyone else has had a positive experience.
That seems kind of expensive. See the other thread where Hyperion is selling 2x1800 batteries and charger for $25 on Amazon.
http://www.amazon.com/Hyperion-Samsung-Galaxy-Battery-Charger/dp/tech-data/B005XOHQ6Y/ref=de_a_smtd
No idea which is better but if Hyperion can provide this I would think Mugen could as well at the same price point. I would wait till it's cheaper or get the Hyperion. Hyperion model already has some good reviews on Amazon.

Hyperion has released a new one, specifically for the AT&T, that doesn't cause the boot loop. The reviews on the Amazon page so far has confirmed this.

Also the Amazon description says to use their charger? Any dangers with using the Samsung charger?
Just ordered one to try. Delivery is in about two weeks. I'll report back then.

I dunno about hyperion but Mugen does give a chart that there is about 9% more juice in the 1800mAh battery...I think if you need a real increase it's better to check a solution with a backcover. 3200mah could do. I used 3300mah on my Nexus S and it was great.
So these extended batteries don't have nfc and they won't charge inside the phone correct?
Mugen Battery will last 1.09 times as long!

Lol, exactly what I've been thinking. Until lithium ion is replaced, the physical size of a battery is a strong indicator of how long it will last. If it's 'barely' bigger. It will last 'barely' longer.

Alright results are in and I'm sorry to say. The mugen battery did not outperform the stock samsung battery. Although it was close. When I got the battery I fully charged and discharged it 5 times as the manufacturer recommended. I did a simple test
1: brightness 100%
2: screen on 100%
3: Pandora streaming 100%
mugen=
Start: 4.190v
End: 3.16v
Total: 5.34hrs
Samsung=
Start: 4.190v
End: 3.025v
Total: 5.49hrs
I know we were all hopefulyhat this would be a better battery. Maybe my testing wasnt the best method, if you guys have a better way let me know so I can retest.

I bought the official Samsung extended battery and am happy with it - at least I'm confident the battery will survive the whole day, whereas the original battery was dead before I finished work...! :-(
Whatever you do, don't buy those chinese 3500mah batteries. They are worse than SGS2's stock battery

Have heard this too - that's why I went for original Samsung... Possibly more expensive but genuine!
I would go with the samsung official extended battery, as the non official ones are not very trust worthy.
I have a friend that works at AT&T and he just sent me a pic of this product they just got in. It is a spare battery charging system with the spare battery included and it is listed at $49. It is on the AT&T website just Google "spare battery charging system galaxy note at&t" and it is about the 6th one down.
(Sorry I'm a noob and can't post links.)
Does anyone have this? Is it worth the buy?
Here's the link for the assist....

personally I'd buy something similar from amazon or ebay before I blow $50 on a charging solution...
OEM original is a huge ripoff!
I bought this, 2 battery with battery charger for only 14.99$ !
I used this battery for 3 days now (I charge it nightly when I go sleep),
and I can't tell the different between this cheap battery and OEM original!
this cheap battery lasts just as long as original OEM!
the battery also weight the same as original, it's possible the battery made by the same company, just a different label.
battery charger works on AC and on car with microusb charging!
I highly recommend it!

The product has been in stores at launch date of the g-note, don't know why your friend's store just now receiving it. As for the item, it does what its design to do. Just make sure to connect it to a charger with more than 500mA or else it will be an all day process. I wouldn't and didn't pay $50 for this product.

If you want the OEM one order it from amazon instead. I bought mine for $30. Better off saving the $20 + tax vs buying it in store, you can pretty much buy 2 for the price of one.

not all non-aftermarket are junk.
I used to have aftermarket battery for Sony x1,
that battery rated the same mAh as OEM
but battery is much lighter and doesn't hold that much charge.
this aftermarket battery for note is heavy, weights the same as OEM.
I have been using this aftermarket battery for 4 days now, it lasts the whole day
I have no need to swap to the other battery. (I charge phone nightly when I go sleep)
I wish someone would make a charging solution that would work with most cases...
