[LG Optimus 2x] Scougar:
Yes. I've now ordered a second "3500" mah battery so I have a spare cover and shell in case I **** anything up. I am just trying to gauge the capacity of the 3500 battery. On my first run it lastest almost 2 days on stock rom, with a fair amount of use. I would prob say only around 2000mah at a guess though.

I'm just trying to get it to run down again for a 2nd charge now.

Once all that's done, I'll open it up and start tinkering :-) I will have to get both the LG batteries to the same state of charge as well (same voltage level) before hooking them up.)

Bear in mind I've spent £22 on original batteries that I am about to hack open for the cells inside, so there is no going back lol. Pretty expensive mistake if I **** it up relatively speaking.
[LG Optimus 2x] shpapy:
no doubt it could be an expensive mistake, but if u succeed which i think you will the results will be probably a 4 day battery. so i think its worth it :-)

i got the 2450Mah battery and it holds about 2 days with medium usage, so im really thrilled about ure test as i dont care about the size of the phone,

if you can share pictures it will be great you can also p.m if u want!!

thanks.

Shpapy.
[LG Optimus 2x] Scougar:
No problem, will do :-)

I charged the battery again last night, and rapid drained it running bluetooth (nothing connected), some GPS usage and wifi with smartshare running a video across from my NAS drive. In the morning it was down to about 25 percent so tried GPS on cycle to work and then drained it with music and GPS until 1%. Charged it without using it, and it's reporting about 1900mah estimated for the battery. I don't rate the estimator as highly accurate btw, but it's a guide :-).

I will try to take the battery apart tonight if I can. Not sure on best way to open it though, as I will need to reuse the carcass.
[LG Optimus 2x] Scougar:
Damn.. was taking it apart and fried the circuit it came with. Unfortunately the metal legs that bring power from either side slipped off and touch the outer shell of the battery, was enough for a small yellow spark :-( oh well. (EDIT: Hmm.. circuit may still be alive actually...)

It's two batteries pressed together with several layers of thin plastic between them, either for insulation, spacing or both. I'm actually pretty surprised the cells weren't isolated better from each other.

Update 1: Well, for the first time.. I just managed to burn myself with electricity opps. These packs are really badly isolated. Shorted it on the tip of my finger... beginning to hurt lol. There are NO ratings on these batteries whatsoever. However, one thing they are is... amazingly well balanced. Just measured them and they are both exactly 3.78V's.

Update 2: The circuit and LG Battery will NOT fit directly into the old casing. There will need to either a mod to the extended casing, or we'll just have to 'go without', and make a casing up. It's looking like it's best to do without using the old battery at all actually, and just wire the two batteries together using the LG circuitry. (Well only one of the circuits).

Update 3: Will dig out the soldering iron tonight and get this double battery running :-)

Update 4: Have VERY BADLY soldered the batteries together and combined battery is now charging in the phone. Due to the excess solder on the sides the battery is not quite proper fit, so I will have to redo it at some point. Really very dissappointed with how awful the soldering is, I will simply HAVE to redo it once this experiment is tested. Any tips on a soldering iron chaps? On the plus side, the one thing I do get is a temperature reading :-D

Tip number 1: Quickly snip the circuit off first and DO NOT let it touch the side of the battery casing, it will short out.

TIp number 2: h t t p://www.technfun.com/pages/article.php?id=22 Excellent guide. Take note of the safety tip!!!!

Points of interest

A) The extended battery is EXACTLY double the width of an LG battery.

B) LG OEM Batteries are made by Sanyo

C) Don't use a conventional soldering iron... it is almost impossible to solder the negative side and you will end up overheating the battery if you are not careful. (Any tips here guys?)
[LG Optimus 2x] Scougar:
Charge battery up last night, and stayed up wayy too late trying to drain it.

Technique... used the 'flashlight' app to keep the LED on, turned on bluetooth, turned on wifi, and use smartshare to stream a movie (at full screen brightness) to the phone. Played Dungeon Defenders for a while as well at full brighness so hopefully the graphics core would take more power. Battery Temp got as high as 40C under 1400mah draw. Odd thing was that battery widget pro at times reported +25000 Mah(ish), yes PLUS '+', and 25000mah, that's just insane..not sure where it was getting the figures from :-(

7% battery left when I put it down, voltage was 3.550 or very close. This morning, voltage it still had 7% left and voltage had increased to 3.7 ish. Guessing it's because the battery was warm last night when under heavy strain, and now it's relaxed and cooled it's feeling better lol. (Or maybe something else?)

Running gps client down now in attempt to drain the rest before recharging. Ideally want to get it down to 1% before a full charge.
[LG Optimus 2x] shpapy:
cool progress , can we get some pictures of the new battery?

how were u able to fit it in? i get u got a bigger case but still....

share with us ure images / knowledge its sounds really cool doing.
[LG Optimus 2x] Scougar:
I basically copied what they had done on the 3500mah battery, and merely connected up the positive to positive and negative to negative terminals of the batteries using thin strips of metal, and only used one circuit from the LG battery. Basically I parallel the batteries to increase capacity.

I used a small spacer to keep the batteries seperated, but thinking about it, I could have use the bodies themselves as the 'negative' but it wouldn't have been a good connection). I then just taped the battery up and use the 3500mah battery sticker to hold it all together.

This really is just a 'prove it works' / prototype, and I will remake it neater, although I may have to buy a better soldering iron.

Pics later.

Note: After charging back up from 1% this morning to 100%, the 'estimated' mah by Battery Widget Pro is 1551mah. This would indicate to me that one battery is not connected properly unfortunately. I'm gonna run the battery and see how long it lasts under general usage. If it lasts only a day and a half, then I suspect I will have to resolder.
[LG Optimus 2x] nothingtotalk:
I bought a 3500mah half a year back and it wasn't any good. Twice the width but lasts the same as the original one. It'll be good if you could show us some pictures? I may consider making one too!
[LG Optimus 2x] Scougar:
To be fair the estimated capacity of the 3500mah was around 1800 to 2000 mah. Pretty good considering it came with an extended back cover for under £5. It does seem entirely random though, and I was never comfortable without a temperature sensor.

The work I have done so far is rubbish to be honest. I thought I'd make a better job of soldering. I will have to redo it, as the fit is terrible due to the solder being too big/messy, and the connections are not very or or not working/broken.
[LG Optimus 2x] tomislav177:
Can't wait to see the results. :-)
[LG Optimus 2x] Scougar:
For some reason, battery widget pro was recording very high mah draw/drain. I do not believe I soldered the negative terminals well enough. I took it apart and tried to prise a little flap of metal up for soldering, and managed to rip the terminal off the pack. I will do my best to remedy this of course and let you chaps know the result.
[LG Optimus 2x] Soulj4h:
I also have the 3500 mAH and I was wondering if it was really giving 3500 mAH. I'm getting about 1.5 days on this battery with moderate usage. Heavy usage I get about a day. I wonder what I'm doing wrong. I think it's supposed to last longer.
[LG Optimus 2x] Scougar:
3500mah battery is NOT 3500mah. It just a lie to get you to buy it. That is why I am trying to see if I can strap two matching LG (genuine OEM) batteries together to get a true 3000mah :-) (or close to it). Just doing other stuff at present. Will try tomorrow to resolder :-)
[LG Optimus 2x] Soulj4h:
Do you think the MUGEN ones actually advertise what they give then? Theirs is 4500.
[LG Optimus 2x] Scougar:
They are better than most, but they do NOT give the 4500mah they claim as shown many times by users (reporting it on web) and battery testing sites. It's a real shame given how much they charge, as they could easily make a decent battery for their prices (not to mention better looks extended cases).
[LG Optimus 2x] Soulj4h:
Right. How can you tell whether it's giving it's stipulated mah or not? Is there a software you can use to test it or does it have to be hardware testing?
[LG Optimus 2x] Scougar:
You would need to fully charge it, then do something like have a constant 1mA draw on the battery until it was discharged, and then see how long it took to discharge. That will give you your reading. If you don't have the tools to do that, then you need to figure out some other method of comparison, like how long a video will play for etc.

Don't get me wrong, I think my '3500' battery was a tiny bit better than the original, but an extra 500mah was not worth it for me over the stock battery, hence my experiment.
[LG Optimus 2x] Scougar:
Sorry for massive delay. I have now got a newer soldering iron with a pointed tip rather than a wedge, and a solder sucker. Hopefully it will be enough (along with sanding the contract area down).

Will either do it tonight, or tomorrow :-)
[LG Optimus 2x] Scougar:
Right, I have resoldered (VERY BADLY) the terminals on this, and gonna do another test tomorrow with it.

Frankly, I have screwed these batteries up so I will have to order another two to play with. I know where I went wrong and will do a clean and properly fitting job next time :-)

The reason I haven't put any pics up is because frankly... I'm embarassed by the really bad soldering. A half blind monkey could have done better lol.
[LG Optimus 2x] Mungulz:
My electronics teacher said my soldering was the worst he had ever seen :)
[LG Optimus 2x] Scougar:
lol.

Well.. I'll try get some pics up then. One side is acceptable, the otherside is a total mess. I will next time cut the connector strips, and solder to those directly rather than trying to get caught up in the battery acting as a heatsink whilst I solder.

Right, here are the pics. Let me first say that I think I damaged the battery as a result of soldering badly (excessive heat). The battery does not perform as expected.

This is the battery without it being wrapped up, but just being soldered.

Here is the unwrapping of an LG OEM battery. The manufacturer is Sanyo.

And here is the unwrapping of the ebay 3500mah battery. (Not the padding between the two batteries.. they are much thinner than the LG OEM batteries, there is no way they are 1750mah per battery)

Here is a size comparison between the batteries in the ebay 3500mah and an LG battery. Notice the foam spacer in the ebay item.

Next move. Deciding whether to attempt this again, but not mess up and ruin the batteries this time.
[LG Optimus 2x] keith1011:
too big and heavy for me :eek:
[LG Optimus 2x] Scougar:
Realised I never actually put a picture up of the 'completed' battery.

Notice that the top doesn't fit quite right due to the bad soldering forcing the sides out making it a bit too tight.
[LG Optimus 2x] JohnnieDarko:
I've read your whole thread and I've got soldering tips for you in case you want to redo this project with less risk of overheating the battery.

1. You need 4 pieces of electrical wire, one for the + and - of each battery. Solder the wires to the battery, while holding the wire with

pliers

, as close as possible to the soldering point. The pliers will work as a heat sink, and will take up some of the heat. Use big pliers with a large contactarea with the wire, so you get the most heat into the pliers instead of the battery.

2. After soldering, you can just connect the respective wires with clip on connectors or screw connectors like http://en.wikipedia.org/wiki/Screw_terminal​

And as for soldering tips, there are many online, but in short:

1. Make sure your tip is small and

clean

. (well you bought a new one so that should be good).

2. First heat up both the cable and a piece of the connector, (this may take a bit longer now that you have a heat sink, like 5 seconds), then add the solder while holding the iron against the hot part. Remove the solder when there's enough (you don't need much if both surfaces are well heated), and after a second also gently remove the tip. There are many good tutorials on youtube on electronics solderings worth checking out, it's also how I learnt it, and I also went from worst ever, to good soldering. :)​

Good luck! I might also try doing this as soon as my P990 arrives. My Galaxy S got stolen last week, so from now on I'll be on these forums lurking. :D
[LG Optimus 2x] Scougar:
What I will probably end up doing is soldering too the thin metal strips that come from the battery terminals. I will snip one side, and the fold it over, so I only have to solder once per side (A total of two solder points for the entire battery). I don't know if soldering that far away from the terminals will have any bizarre effect however.
[LG Optimus 2x] JohnnieDarko:
That would definitely be cleaner solution than what I proposed, just make sure to clip something of metal (pliers) onto those terminals as a heat sink.
[LG Optimus 2x] Scougar:
I will probably not reorder the batteries until next month, so update won't be for a while.
[LG Optimus 2x] world_of_ursus:
I'm using a 2400mAh extend battery with new back-cover for 1/2 year. The phone is now about 15mm thick :( but batt-life is more than just noticeable increased. not Problems so far noticed. if sensors are working correctly, lg-battery worked at cabout 30°C in my device, die larger bat is running at about 22-24°C.

Bat health-stat is ok, so no nead for me to change to a 3000+mAh one.

Right now, beside of size of the phone, i only can recommend using a larger bat, caus the orign one is really underdimensionated for medium use.
[LG Optimus 2x] Scougar:
There are currently no aftermarket batteries (like you have) that have a working temperature sensor, that I am aware of at this moment in time. Basically, that thick battery is NOT reporting the correct temperature.

If you want the temp sensor you will have to do something like swap the circuit board over from an original battery or do what I am trying to do lol.
[LG Optimus 2x] world_of_ursus:
Thats not my Problem. I dont care about that info. As long as i dont geht a branding ;)
[LG Optimus 2x] Scougar:
OK, I was only letting you know that the temp reading is bogus, and it doesn't actually run any cooler than the stock battery. I have two extended £4.50 batteries.. I am NOT gonna spend mega money on a branded battery because they are normally not much better than the really cheap ones.
[LG Optimus 2x] R0B3RTF1SH3R:
mate that was the best read in a long time, esp when lookin @ the days pass in posting, what now? i wish you could find a way to fill the bulk of that huge extended cover full of "battery juice". lol. make a prototype. you know you want to.. "+thanks many"

---------- Post added at 11:33 AM ---------- Previous post was at 11:30 AM ----------

SOLD!
[LG Optimus 2x] Scougar:
lol. I tend to waffle a bit though!

I have now sold my LG Optimus 2X unfortunately, so I won't be able to attempt it again as I don't have a test phone. My biggest mistake was not soldering to the metal strips, and trying to solder to the casing. If you attempt it.. solder to the strips :-)

I might be able to attempt it again on my Evo 3D (to 'prove' it).. but the oem batteries are much more expensive than the LG's :-(

[LG Optimus 2x] SuperSkill:
Crap.....I've bought and tried 3 batteries for o2x, cheap from dealextreme, whether they claim 2400ma or else they last the same as original. On my defy the 5$ battery are even better than original. Even for my camera I bought 3 batteries, first one didn't work, 2nd almost as original. My conclusion are simple, I buy the Crappy batteries as I need to have a charger with me anyway :) as for camera I use Crap to, original battery are half the price of the camera(phone too).

I got that same 3500mah battery and it turns your phone into a brick. A bigger problem do is that I havent seen any difference betwen it and original, and I marked it as a waste of money.
[LG Optimus 2x] Scougar:
That's a shame.. the 3500mah one's I got worked out to be around 2400mah in reality. Not too bad for the money, and it DID extend the life without a doubt. My real concern though was the lack of a temp sensor on them :(
[LG Optimus 2x] ahnuc:
+1 :good:
[LG Optimus 2x] Scougar:
No I'm not. The battery you linked to isn't genuine as such (By that I mean it isn't 'LG'). It's an after market battery that STILL doesn't have a temperature sensor as far as I'm aware. That isn't to say the Seido one's are not any good, they are good - but - they cost a lot of money for what you get.

I would build another one, but better this time if I had another O2X, sadly I don't.
