I am initiating my third project this winter season.
Purpose of this project:
The project is to successfully make a 9600mAh battery @ 3.7VDC.
Objective:
Use least amount of resources. Battery should be created easily by anyone. Budget is less than $100 USD.
Materials:
3x 3200mAh Li-Ion batteries
4x Copper conduit cables with plastic wrapping
- 2x Copper cables 5mm Width, 4-5cm Lenght.
- 2x Copper cables 1-2mm Width, 4-5cm Lenght.
1x Tin (Sn) Soldering Unit.
1x 2-3cm battery door.
Procedure:
1. As you see there are 4 compartments of power conductor on the battery (metal copper) where the battery touches the Universal pins.
2. Stack up all the batteries so that they are one over the other in same position parallely.
3. Take the copper cable and connect it to each batteries metal spot. Ofcourse the bigger compartment is going to require the 5mm wire and the other small ones will require 2mm.
4. Solder the wires tightly and they must touch all the compartments.
5. There should be a little bit of wire left in the end and that wire must touch the first battery a bit.
6. Make sure you do not use excess wire otherwise all the batteries wont fit in the battery door.
7. The first battery will clip into the Universal but now here is the modification you have to make to the other batteries.
Break off the clips on the other batteries. Front and back slip in clips. This will enable the batteries to fit in the case and probably make room for the copper wires too.
8. Now here is the problem. If you are making a 4800mAh battery stack (3200mAh + 1600mAh) then you are lucky and can custom order a battery door. For the other people making 9600mAh or 6400mAh you will have to make your own battery door probably by using molding plastic tools.
Now please keep note not to ever ever ever solder anything to the pins on the Universal power recieving wires. Otherwise you are in big trouble and probaly damaged the power supply but you can cut the solder off.
Results:
So this is the array of batteries you have just built. I will built a 5000mAh battery so this is how it will work for me. i have a 1800mAh battery that is of normal flat size and a 3200mAh battery. Both of same 3.7V ~ VDC. Therefore, we can conclude that both stacked. The wires were connected parallely and i preffered to break the clips on the 3200mAh battery since my 1800mAh is metallic. I asked Lion Battery to send me a battery door for their 4800mAh batteries and they arranged it for $10 or something and it fit my battery stack because it was approximately 1cm extended.
So first the wires were soldered on the 3200mAh and then they reached down to the 1800mAh. The 1800mAh connected independently to the pins on the Universal. The Universal is now drawing power out of both 3200mAh and 1800mAh batteries!!!!
Conclusion:
I saved $200 on a 5000mAh battery.
Good luck on making your battery stack. Try to post pictures and information if you to undertake this project and are successful.
Regards.
I will buy only if the size remains the same size as 1620mA original battery.
Anything beyond the size is bulky, considering Universal itself is already bulky.

I agree. The maximum available at flat size is 1800mAh. Single Battery. But the point of having the universal is functionality. I dont use it to talk. I use the BT headset.
nuclear
Use car battery and you solve all their own problems
.Will much long work!
Show us photo your super batteries!
If will be a photo we all shall believe that you technical genius!
It would be a Nuclear device...beware
You should realy start to think about your 4th project:
Making BAG for project N3
Guys be nice...
Nuclear any chance of some photos? Put them on Flickr etc.
What kind of usage time do you get?
V
YES, be nice... because in theory as long as you connect the batteries in PARALLEL you are not increasing the voltage, but you are increasing the capacity, thus longer battery life. As a matter of fact, you can stack as many as you want.
Now if you are connecting the batteries in SERIES, then you are going to fry (TOAST, if you prefer) your precious Universal.

Offcourse I'm joking - but actualy it will be powerfull Universal without chance to put him in .... pocket
i was just thinking of this last night, and there a thread.
anyone have any idea how to make a battery door, or what i call it a battery cover with ease? i do not own any plastic moulding tools

I find making a battery cover/door very easy personally. I did not post upon how to make a battery cover/door but after a lot of thinking i have come up with the procedure to do that too.
1. Order 2x 3200mAh batteries from ebay or anywhere you like. The batteries will include their individual covers. Note that you must order the battery with the square black door and not the aerodynamic silver door. You can also order individual battery doors from ebay by requesting the seller
2. Therefore you will be making a 6400mAh stack of battery.
3. This is where you have get to make a choice. Either to keep the batteries in one compartement or to keep the batteries in separate compartements (recommended).
4. Keeping the batteries in separate compartements helps in cooling effect and prolongs the life of the batteries because batteries emit EMF waves that could damage each other. When the batteries are kept separately they have no chance of effecting each other.
5. Also note that the batteries charge and discharge simultaneously due to charge distrubution factor of 1/2 .
6. Ok now to make the cover. First we will look at the single compartment where both batteries sit together.
- We have two covers and classify them as Cover A and B.
- Cover A will clip into the Universal directly.
- Cut out cover A's roof using a hot cutting knife (recommended to keep soft edges). Let the Cover A cool down and you may now throw away the roof of cover A.
- Cut out the base or rim of Cover B. You know the rim that sits on the Universal. The flat rim part on Cover B must not exist.
- Cover B must now look like a perfect rectangle without any edges because it will sit on Cover A and you will attach them by heating up Cover A and Cover B edges so that they both bond up. You can make this bond either by using permanent glue or moulding using a chisel heat knife.
- So now you have successfully made a 6400mAh battery door. Make sure there is enough room for the wires to pass. Good luck.
7. Now to make the separtate compartement battery holder.
- Cut out the rim of Cover B using the hot knife method.
- Make Cover B sit on Cover A exactly in the same co-ordinates.
- Mold them back and make the bond between Cover A and B so now they are Cover A-B.
- Make a hole in Cover A's roof so you can pull out the wires that are going to Battery B in cover B. Make sure that the battery is first in cover B and you solder the Cover A and B with the battery sitting in Cover B. You wont be able to take out the Battery from Cover B because now it is sitting permanently in Cover B fully SEALED! . Make sure you don't solder the Wires to Battery B before this step.
If additional space is needed or the batteries are heating up, just use a metallic 2-5mm stick to make a gap between Compartement A and B.
When i start doing this i will post pictures of the battery stack and my new battery door.
Good luck in making your battery door.
By parallel battery stacking i mean that 1 wire goes through all the batteries touching each batteries metal compartment, since Universal batteries have 4 of these compartements we going to have 4 wires touching each of those metal parts. All the 4 wires must run parallely without touching each other. And that is why we cover them with plastic.
Now if I am correct a series connection is where all batteries connect directly to the Universal, which will fry the universal due to excessive voltage input around 10-12Volts. When the batteries connect all in line then its a parallel and voltage input does not change. Its only the capacity that changes. But you must make sure a wire is running directly to the universal and all the other batteries are connected to that wire. Its like a branching except the main branch connects to the Universal and all the sub branches are the batteries.
I will post pictures when i get home of what i am looking for. It seems words arent enough. Pictures Pictures Pictures!! and Diagrams. I know you all want to see the blueprints. Thats why when i go home today i will make the blueprints in autocad or by hand and upload pictures here. I will also show you what series connections are and how you can fry the battery/Universal if a wrong connection is made.
I personally wont be attempting this project until i make a good cover for the battery. I will ask those 4800mAh battery sellers to give me a cover without the battery for $5-$20. Dont want the 4800mAh battery from those sellers $200 .
Actually now that i think about it i would like to stick with 1800mAh only because its so flat with the universal and not at all bulky. But i dont care about the bulk because i never use the phone to call. Like i never hold it to my ear. Always use a BT headset. This bulk battery is seriously going to be heavy.
Truly I would advice you all to stay with the 1600-1800mAh battery until a new battery is released of the same size with higher capacity.
Okay if you guys really want me to attempt this project I will. But I wont be using that huge stack. Also if someone could help me I would really appreciate it. Afterall I am trying to help you guys too. I dont want you guys spending so much money on something thats so cheap. You guys already spent a lot of money on the Universal and I suggest you dont get cheated by this battery thing. Thats why I didnt have any pictures. But i can atleast provide blueprints. I am doing all this for you guys and not personally for myself. I could have done this project at home and never let any of you know. But there are some days when I am struck and I come looking for help on the internet and i get that help. Thats why I would also be a part of that help and help other people with all I have to offer. So please dont get mad if i dont have pictures or my setup does not work. I am trying my best.
Parallel Battery Stacking
My first picture of how parallel stacking should look like. This is one of the blueprints i post. Make sure your wires are minimal. Very small wires otherwise the batteries wont fit in there. Even the cover must be able to support the wires. If you are making a twin compartment battery case, then better make holes in the partition for the passage of the wires. I will post a blueprint for that too, the cover that is. The key to success in this project is to minimize wires as much as possible.
Also good news! A recent technology has been invented that lets you charge your electronics on wireless!. Plug in the adapter into the wall and there you go. You have wireless charging. I saw this news somewhere I dont remember exactly but I know it was a valid news source.

As you make the wires thinner, they will get hotter/the resistance of them will go up, causing more power consumption

As has been asked before for your claims, links, sources... come on man, we can't take your word for everything.
Another alternative ... although not as much fun as making one
I had the same problem of not having enough battery capacity, especially since the original battery starting going bad (it would shut down at about 50% charge, lasting only 30-60 minutes). So I had the choice of getting the original battery for about $25 with shipping or getting the 3150mAh Li-ion Battery for $35 with shipping. I got the 3150mAh about a month ago and have been very pleased with it. It easily lasts 4 hours under full load and I could go a whole working day under normal use ... amazing !!! Also, it actually feels better holding onto the device, since it's easier to grab onto with the indents on either end of the cover. It's wonderful, not having to worry about carrying around my charger everywhere. I ended up getting it from www.Gizmos2Go.com (http://www.gizmos2go.com/xcart/search.php?mode=search). They were out of stock when I ordered it, but were very nice about keeping me up to date on the progress. Although, it's available elsewhere, so shop for the best price ... http://www.google.com/search?hl=en&lr=&q=Li-Ion+battery+High+Capacity+3150+jasjar.
Another alternative I use is to use a mini-USB "batter extender" that works with 4AA batteries. It's worked well with the Universal with Li-Ion batteries. Here's a link to one of these types of chargers ... http://www.pocketpctechs.com/main~u...ries-power+accessories~item~USB-BATADPT01.htm.
I know these aren't nearly as much fun as making one yourself, but they both have worked well for me. Anyways, I hope this helps someone make a decision.

Hey thanks ollie, this helps a lot. I really like external power, 4AA batteries are nice. I can use my AA 2700mAh battery and 4 of them will make the Universal last a long time. I really like my 1800mAh battery and with this external power idea i can use my universal for a long time. I use my universal in my car, office and work. I am mostly using my headset so make/answer calls. So I could stick to the 1800mAh and put my universal in a leather case and belt clip and carry it around. While i want to play games or chat on msn i can hook up the external AA batteries and the batteries will be in my pocket while i am using the universal.
Yes thats the one and last thing i want to know. If the cable is long enough to hide the AA external batteries... atleast 60-100cm
Pics
Nuclear,
Your project really intrigued me. Do you have any pictures of your work in progress or finished product? Thanks.
I have a Sino battery from eBay, insanely cheap (something like £16 shipped) with the bulgy cover. Works brilliantly.
I'm amazed by some of the claims of poor battery life. I make very little use of my device, but I also seem to get 4 days+ of standby/occasional use with this battery installed! As in, take it on holiday, show it to people, make a couple of calls, play a couple of games, bit of WiFi in the pub - that sort of thing - and it had 39% charge after four days.

I think nuclear means shorter, not thinner - reducing any resistance
"Borrowing" some info from here, I successfully implemented kind of the same technique on my Ringke SLIM case.
The benefit of this is that you don't have to dismantle the phone at all ...
I'm really pleased with the result.
I have here some pictures. I was too excited so I did not took photos of the entire process but the ones who might try this can combine the original tutorial linked above and these photos to understand the process.
The case was modified on the inside but you can not tell this from the outside .
The connectors are made of metallic copper/steel springs shaped as the case. The tip of the connectors have small soldering lead balls trimmed to fit the pogo holes. In this way there is always a little pressure on the connectors and the contacts are perfect.
And here is a short video with the final result/functionality:
that is fantastic. nice work.
"you are my heroooo"
How long does the nexus have to sit on the touchstone before it registers that it's charging?
are there any concerns of overcharging?
(like if it were left on overnight)
Does it charge as quickly as a usb plug?
I only can answer the following in this moment:
-The "charging" message is popping up in about ~10 seconds after placing the phone on the dock. This delay is normal for the docks with pogopins (this case) because the phone needs to know it is placed securely in the "dock" before it will start charging itself. Otherwise, if the charging will begin instantaneously, there is always the danger to play around with the phone (like putting in and taking it put quickly) and the battery will have to suffer.
- The voltage output of the induction circuit is 5V, exactly as the regular charger and the voltage is being applied on the pogo pins, exactly like the original dock => no concerns of overcharging.
As for the charging current and how long it will take to implement a full charge ... it seems that is charging 20% per hour (compared with 30% per hour if I'm plugging in the wall charger directly).

In the thread linked-to in the OP, it's been reported that there's a correlation the charging delay and custom ROMs.
At least one person whose handset is running stock ICS is able to charge with no delay whereas everyone who has reported a delay is running some sort of custom ROM.
Not sure if that's just a coincidence borne of a statistically-insignificant sample size but it certainly seems like there's more to the delay than meets the eye.
This is seriously cool, and very non-invasive to the actual phone! I might try this myself
Excellent work,
and...it is not easy for me
Very cool, I wonder if you could use an extended battery cover with a stock battery and just build the inductive charger into the cover. Not sure if you'd be able to run leads straight to the battery, though, might still have to go to the pogo pins so it might be a bit invasive still.
what material did you use to make contact with the pogo pins?
I'm wondering what you used to carve out the inner part of the case?
What does it say under settings -> battery? Is it USB or AC?
And what steps are the same compared to the linked method in your first post?
Fresh from my GNex
Good job ro, as usually.

All these questions have answers in the attached photos .
For the contacts to the pogo connectors I initially used some aluminum foil but I saw (in few hours) that the contact was intermittent so I looked for another solution. Currently I've implemented two metallic connectors with a little soldering lead on the connector side so it will have a 3d shape that will fit the pogo counterparts (I've updated also the OP with the new connections).
The common part between my mod and the original one is the usage of the same touchstone parts, the "dismantle" of the palm battery cover, the voltage tests and the general way the connections are done. Basically is ~80% the same stuff only that is not being applied to an extended battery cover.

You want want to read this thread then, as well as the one the OP linked-to, both of which are dedicated to that very idea - fitting the charging coil and connection to the pogo pins inside the handset.
I took a short video with the final result: http://www.youtube.com/watch?v=QOgMZt2xk_0
In the second part I've activated "Desk Home" (an app that will trick the phone into thinking it is docked when you plug in a charger) and I've triggered "Night Clock" with it
Excellent! Great use for parts I have left over after the old palm pre died last week.
Can it charge faster than GPS usage + Pandora can drain it? Thats something that would interest me. If i could use it in the car, pandora + navigation running, and actually have it charge. Would ya mind doing a quick test for me ?
This is exactly what i was looking for. Did a search on here, other forums, and even threw a few keys words googles way and didn't come up with anything until tonight when i saw this. I'm going to have to get something like this setup as i already have a wireless charger (same standard as the palm puck) so it's only natural to want to use it. Would you have any recommendations on what case to use with the LTE version sporting the extended battery?
@machiz7888: The inductive coil is transferring about ~400-450mA (equivalent to about 1.6-1.7W of power).
our device is draining about 1.2W just using the screen at maximum brightness (the standard car situation). If you are using navigation with the screen on and pandora at the same time, there is no way the coil will ensure the necessary power to sustain the full phone activity => the battery will drain a little.
Just turning off the screen should help the power balance and the phone should charge even under heavy load.
@stearic: The only case that can be used similar with what I did but for the LTE version would be the Case Mate barely there. I have no idea for extended battery what you could use. I'm also searching for a solution because I already ordered an extended battery and I don;t want to be force to choose between the two things (inductive charging or ext. batt.)

I Googled it for you, second link down, give it a go, it's really easy.
The first thing you’ll want to note is the dock will not work with the LTE version of the Galaxy Nexus, however, it will work with either the stock or the official extended battery for the GSM version of the phone, though the fit is noticeably more snug.
Thanks - I did look round before i posted the question
Verizon Pogo Pin Dock works with extended battery
I can affirm that the extended battery works with the pogo pin dock that is available on samsung's website. It's a bit of a hefty drop for $95 with tax and whatnot but it's well worth the money. also, it may be interesting to note that there is a bit of a 2-4 second delay sometimes for the phone to register that it has been placed in a dock. it goes straight to the clock when it has been docked.
Samsung website: (I would post the link but I can't because I haven't posted 10 times yet) -__-
NOTE: The model number of the dock that is compatible with the CDMA version is: EDD-D1F8BEBSTD
hope that helps!

$95 is a tough pill to swallow, but I'm thinking about it, because I will probably end up keeping this phone for the full two years of the contract I'm on.
Does the i515 dock work OK with the OEM extended battery?
And a couple questions I have about the phone's behavior in the dock that I haven't seen answered in any threads about the dock:
When docked, the phone is supposed to go into the landscape clock mode. Cool.
1. Does the normal screen timeout setting work? (does the screen turn off after x minutes?)
2. How do you turn the screen on and off manually? The volume buttons?

* Yes, clock mode or another app can take that over if you desire if the app supports it.
* Screen respects the normal timeout settings EXCEPT if the screen saver clock is on, then the screen never times out. To prevent the screen saver you need to use an alternative dock app as per my point above.
* Reactivate the screen by either modding for volume button wake or removing it from the dock and pressing the power button.
Samsung/Google didn't anticipate needing to use the power button (it's inaccessible) I suppose because the screen is never off with their default config... they just didn't consider alternative configs.
They should have included a 'wake/sleep' button on the actual dock.
DJ, Thanks for the reply.
Yeah, it seems that the dock was not very well thought out, and that its interaction with the phone was also not well thought out. It really disappoints me, as when I bought the GN back in December, the (potential) availability of a desk dock was one of the features I really wanted. I had a DX prior to the GN, and used the desk dock every night. My phone is my alarm clock. However, in that function, I need to be able to turn off the display and turn it back on easily.
It also seems the CDMA GN is kinda the 'bastard stepchild' of the family. The GSM version can get the dock on Play for $55. Us CDMA owners are stuck with getting it from Sammy directly for $90.
I've got a Nexus 7 on the way, and noticed that it also has pogo pins. Hopefully ASUS won't screw the pooch or fiddle around for more than 7 months on getting accessories out.
It just really seems to me that Sammy doesn't give a **** about the GN. They were like "here, Google, have fun, see ya later!"

The CDMA phone and the GSM phone are slightly different thickness wise.
I think the GSM dock can be 'massaged' (read: use a dremel on it!) to fit a CDMA phone.
The situation is still rather laughable, IMHO.
hi guys , I have a galaxy nexus desk dock ,but a question annoy me that the first option of dock setting(audio) is always grey and never active it when I put my phone on dock. In my nexus one dock you can active the first option of dock setting(audio) and then you can answer incoming calls and listen music transfering by buletooth t. In galaxy nexus dock what i have mentioned is impossible thing because you only listen music by line out . and why ?who know it please tell me ,thx.
Has there been any word on that rumored wireless charger for the GSIII from Samsung?
Are there any worthy 3rd party wireless chargers?
No. Samsung pretty much keeps pushing it off from what I heard. Buttttttt, I think some Chinese or Japanese group made a modified back cover for the S3 so it's compatible with a wireless charge station. The group sells them on ebay I believe. You'd have to go find it and what not I don't know price or anything like that
Edit: there seems to be a bunch on ebay that are receivers which you take off the back, and attach it in, put the cover back on, and then apparently your good to go. I don't see any specific group who made them but there's several all around $20-30. There was a post around here on the same thing.

Bought one for the verizon variant and modded his phone slightly to make it work, didnt sound like it was a full teardown process or very difficult either
There's a lot more simple ones than that.. they attach inside the battery cover (the back of the phone you pop off to access the sd card, and battery).
Pretty much if you take off the back and look on the left side by the battery is 2 little copper looking squares or w/e, thats for a wireless charging receiver.

All you gotta do with that, is take off your stock battery cover, and put that one on, and then set it on a dock. Due to it somewhat covering part of the back of the phone, (not visually from the outside), it may interfere with NFC/S beam. Im not sure about that though.

Here you go. Great option for me cuz the wife used to have a Palm Pre.
Without some way to suppress alert tone, wireless charging is a bust

The NFC antenna is in the battery, so the wireless charging solutions that involve covering the battery (like the one you linked to on eBay) definitely will prevent you from using NFC.
I took the Verizon OEM wireless back (available on eBay) which has the second NFC antenna below the battery (i.e. NFC still works) and did a 10 minute mod so that my Sprint phone would accept it. I'm still a noob, so I can post links, but Google for "How to EASILY Add Inductive/Wireless Charging to your Sprint Phone Using Verizon Cover & Keeping NFC" and is the first link
Been reading some of the other topics here trying to learn which is the best choice for an extended battery for the T989. I've seen praise going out to Anker and EC Technologies, an extended battery for the Galaxy Nexus, someone having decent luck with a battery with Chinese printing on it, etc.
So let's make this simple...
1. Is there a definitive list of which batteries have consistently shown better performance over others and have shown to do at or above the expected return compared to the stock battery?
2. Are there any particular companies/brands/etc to avoid at all costs? As in, so bad that even manufacturers of other below-par extended batteries can honestly brag about not being THAT bad.
3. From what I've read and learned, most non stock batteries don't support NFC. Are there any reliable extended batteries that do? Are there alternatives to keep NFC available even if the battery doesn't support it? I have a feeling the answer is no to the last one, but I could be wrong.
Not really battery related, but charging related...
1. I've come across a dual purpose charger with the Sprint name on it (via ebay). It plugs into a car but you can unfold prongs on it so it can be plugged into the wall. On the end (away from car adapter), there are two USB ports (one open, the other you can uncover when needed). Are those any good? Main interest here is the dual USB option as well as being able to use in a car or in a house.
2. I guess more importantly would be, are the accessories seen on ebay generally reliable (Buy It Now auctions, reputable sellers of course)? A lot of the car plugs I've seen look like I wouldn't have much to grab to pull on when needing to unplug it and that worries me. Also concerned about the quality/safety/reliability of the products and thus the question. If they are all pretty much "all the same" just different looks and such, but otherwise all safe, then that's great.
3. From #1.. Are there any reliable/reputable car/wall chargers that provide more than two USB ports? Like the idea of it being a single car/wall charging unit, but if it's two pieces (with more than two USB ports each), that works too.
Ever since getting and starting to use the T989... Wow, I wonder what I'm doing to cause it to need to be charged 20 times/day. (Not literally.)
For the record, I had made the slight boo-boo of getting a pair of the cheapo 'extended' batteries before reading up on them. Not too bad though, doesn't hurt to have spares. I saw a reference to recalibrating a battery, but when going into recovery mode, didn't see an option referred to for resetting the stats. Are there any decent guides for proper care of a battery? Best practices when first getting it, when to charge it, not charge it, etc.
Thanks for any help provided. Now off to enjoy my phone some more. Haven't talked much on it yet but hey, only had it about three weeks.
for your answer for number 3 there is an app called super beam if my memory serves me right and has a blue kind of wifi signal and should serve as a good NFC "alternative"

By alternative, do you mean it's not NFC but serves the same purpose? I'll definitely check it out, as I can see the usefulness of NFC. Still would like to know if NFC itself can be accomplished when using a battery that doesn't support it. Actually, more of, wanting to understand it just enough to know if it's possible and how (if so) or why (if not). I hope that makes sense.
I had tried bump but that was a bit of a disappointment. Will try looking for 'super beam' and see if I can find it. Thanks.
Edit: Found it.
SuperBeam (com.majedev.superbeam), without a space in the name. Looks promising, will try it out.

Basically if its not a well known, reputable brand name (samsung) they have no reason to be truthful about mah
Most of the no brand batteries are equal or lower mah than stock.
If samsung could fit more mah in a battery of that size, why would they not?
For charger testing use this
http://forum.xda-developers.com/showthread.php?t=1801608
Higher numbers = faster charging
The max the phone will pull from a good charger is around 800ma, usb ports on pc's are limited to 500, which equals slow charging
:edit: not sure if this deal is still going, but alot of people (myself included) got free galaxy nexus extended batteries here

It is a little fat for closing the back fully

Profits come to mind. Could be that they intended to sell an extended battery but in the end never did (did they?) or wanted to leave room for improvements as a selling point in the future. I'm sure you know companies will do that sort of thing to stay in business.
When I asked about ones to avoid, I meant if there are any particular ones that are the bottom of the barrel, even among 'generic' batteries. Perhaps identified by the label itself even if it doesn't have an actual name on it. Would still love to hear feedback in regards to the more popular batteries, as I don't want to order a pair from Anker and then come across a group praising some other brand (for example) and of course, vice versa.

So aside from the back not closing 100% (or can it with some effort?) it works in the S2?
Edit: Found answer in Galaxy nexus battery, apparently it does. Ordering one as I update this post (shipping is $6.50, not a bad deal for battery and cover).
I modified my battery, with a file. The result is a less buldging door
http://forum.xda-developers.com/showpost.php?p=40550113&postcount=180
Oh and the cover is only for the Gnex, you have to use your stock t989 battery cover
In terms of 3rd party batteries, anker is supposed to be one of the better ones.
Search the forum for anker broke to get an idea if the "best" third party is any good

Yeah I figured as much, still not a bad deal. I could probably sell the back on eBay, so that someone else ends up with it. Might not matter too much with the bulging door, as I'm using one of those 'Heavy Duty Rugged' cases. The one I got on eBay is item # 620107891193. Not really into the idea of doing anything to a battery, for fear of causing it to leak or something else which causes problems.

Will do. Still need to check out that app you mentioned in the previous post.
When I first looked at the deal link you provided, the date alone had me thinking, "Oh yeah, this is likely long gone..." but decided that I had nothing to lose by checking it out. As you probably guessed by my last post, it's still good. Many thanks for that.
