Has anyone tried one of these cheapo ebay extended batteries?

Found this extended battery on ebay, was wondering if anyone on here has tried it, i know it looks hideous, but if you know your making a trip somewhere it could come in handy if it works the way its supposed to. Its cheap as hell too.

9 bucks... can't be too great,
but what can you lose? lol

Seems to me that if the larger aftermarket brands have trouble meeting the stated mAh rating on their batteries, what more of unbranded ones that goes for an even lower value?
I also still have very clear memory on exploding phones from third party batteries years ago

I bought a cheapo 3800mah and it lasts barely longer than my stock extended battery. I wish samsung made an official 3800mah version

Buy 2 stock batteries and solder them together. Works great.
3500 real mah. I didn't think the 2000 extended batteries would fit under the cover from the Hyperion I had here. I agree though, if I can solder it up in an evening, Samsung certainly could work up something.

hopefully more phones in the future will be like the razr and give us a factory extended battery closer to 3000mah.

Razr maxx when I had it for a week was sick! Hard use all day, charged every other day, seriously insane battery life. If that phone ever gets bootloader unlocked, I would be all over it again.

Have you done this solder thing? Any tips?

if you look at the battery in the phone you can see that there is some space at the top of each terminal, use this space to solder a fine piece of copper wire to a second battery. make sure to solder the batteries in parallel, positive to positive and negative to negative, to retain the same voltage.
i remember taking apart a so called 3500mah battery from ebay and they were just two cheap 1500mah batteries tapped together. Apparently in china 1500X2 is 3500.

Why does everyone want extended batteries? 99% of people have access to a power cord most of the day and just don't need it. Granted, I'm new to the phone, but I really hope I don't need to carry around a huge battery or two. Personally I'd rather charge it more often. Just my own opinion.

I bought a 3600 mAh extended battery for a few dollars on ebay. Despite the fact that it makes my phone look like a beached whale, it totally got rid of my power shortage anxiety. My most useful ebay purchase so far..

Even If it's 1500 that's still 3000mah for less than $10. Pretty good deal.

As long as you know that I don't see a problem. Spend $10, use it for 6 months, buy another one. Much better than spending $100 for a mugen.
Even the Samsung batteries lose their capacity over time.

Samsung 2000mAh VS. Anker 1900mA

So I was thinking of buying an extended battery,
since i can barely last a day with the original one.
So what are thoughts?
Samsung 2000mAh OR Anker 1900mAh?
Or maybe another battery?*
Thank you
*Please no 100,000mAh chinese batteries..

It is more expensive than Anker battery but it gives more juice (20-25% more than stock) and many people say that the phone feels better in hand with some extra weight and thickness.

I also say go for the 2000mah by Samsung. There's a significant improvement in battery life. The larger battery also doesn't get as hot. and the phone's back is now flat.

Seriously, don't fall for that super mega over xxxmAh class A or whatever made from wherever. I'm having a great experience with the Samsung one, gives me additional 3 hours (at least) with heavy usage. I'm quoting one website that describes it "the S2 that should have been" which is true enough, at least from my experience.
I promise you, you won't regret adding some more off your pocket to get one... heck I even ordered it online and shipped it from abroad!

I am ordering it from abroad as well..
Know of any website that sells it for cheap?
Best I found is 40$+- with shipping*.
Thank you all

P.S
Is there any case that supports the.new ''fat'' cover?

Was it from an online shop or real one,because here in Bulgaria its 35 euro at least?

Most Romanian online shops have it at less than 20 euros, with a back cover included.

I got a pack of 2 ankers and a charger for 12 quid. Amazing.
Spent 3 days getting drunk on a scottish beach and still had battery , you can charge a battery and the phone at the same time and the batteries are small so carrying a spare is no big deal in my opinion. That way you're looking at 2 additional days charge.

Here is a link to ebay to a extended battery for galaxy s2.
Its 3500mAh and also comes with the battery cover.

I've had good luck with Anker batteries. No, I don't work for Anker or anything like that at all, just a satisfied customer. They make good quality batteries. I don't have any experience with Samsung batteries, so I can't comment on them.

Galaxy Nexus After Market / Third Party Batteries with NFC

Has anyone found any on Ebay or else where that have maintained true NFC functionality?
I've seen a few on Ebay but the labeling is so "China town," I don't know if I trust them.
(no offense to any Chinese )

Did you try Amazon? I think Seidio makes some.

If you want extended look for Hyperion brand. Got it on eBay for $20 and the nfc works great. Battery life more than doubled too. Well worth it.

The most reliable battery makers are
Seidio
Mugen
Both have 3800 - 4000mAH batteries available with NFC support. Will cost ~$90 though.
Do NOT get the cheap-o batteries selling on ebay.

Seidio or Mugen don't use any better of a battery than most of the cheap ones. You are just paying for a name and false security.

Those battery are also made in China. You just pay more for their brand.
And those two brand don't even have their own factory.
I just got my 4000 mah battery with NFC for 10USD. It also works well.
And of course, they're made in China.

Hyperion review
Just got this that arrived yesterday morning:
http://www.amazon.com/Hyperion-Exte...APABILITIES/dp/B007C8XRJY/ref=pd_rhf_gw_p_t_1
I guess I'm one of the lucky ones, after reading reviews, because the cover that came with my snapped right on, with no problem whatsoever. I started fitting it at the bottom and worked my way around snapping the clips in and wala - perfect fit.
I also bought this cover:
http://www.amazon.com/Hyperion-Exte...ompatible/dp/B0083HHU5A/ref=pd_rhf_gw_p_img_2
It's black/honeycombed and fits perfectly over the new back, giving the whole phone a factory made look. The only "negative" to it, is the volume buttons and the on/off buttons are now alot more sensitive - the cover goes over them and it doesn't take much now to depress one of the buttons - I'm actually liking it more, as I get used to it, but I imagine you could carve the rubber off at the buttons with a knife if it bothered anyone.
Anyway, after reading the little card that comes with it and the "charge it for 12 hours, kill it 4 or 5 times cycling" - I plugged it in and after about 2 hrs, it was saying fully charged. I needed to use my phone, so I turned it on - made a couple phone calls with it and decided just to use it. I read cycling doesn't matter with a Li battery anyway, and I was just excited to see if this thing was for real.
It's 10:43 the next morning - my battery has 19% left on it and it has been on the battery for 18hrs, 8mins when I unplugged it yesterday!!! I am a heavy user too - all throughout yesterday, played a few games, many visits to facebook, web surfing texting, 10 or so short phone calls - then again this morning, surfing the web for a good 1.5-2hrs gathering news.
All I can say, is this is unheard of - I've NEVER been able to do this on the stock battery. I'm going to run this all the way down today, so I'll post back when it actually shuts down, but it's for real folks - order it! I'm thinking about ordering another one for backup - I'll only have to charge once a week!

In this case, quality matters. I've already researched the differences. You won't be getting as good battery life as the one's from Seidio or Mugen. Please do the research before saying such things, as you're misleading others.
It's already been confirmed that the cheap Ebay batteries are of low quality.
Just because it's Made in China, doesn't reflect the quality of the build. Seriously? Everything is made in China...
Look through the posts on this forum about the ebay batteries. Almost everyone says they found barely a difference with extended battery.

Your statement doesn't stand. You're insinuating that the cheap-o Ebay batteries are just as good as the Branded Seidio / Mugen batteries, when that is clearly not the case.
Shifting the goal posts aren't ya. Seriously, stop spreading misinformation. I gave you at least 3 sources from various forum members that concurred the battery life discrepancy is vastly different between the generic and branded ones. (Mugen/Seidio)
Did you provide a source showing that the generic ones off of eBay have as good or better quality than the branded ones? Looks like no.
I have sources to back my claim up, you have, well, none.
example of a bad battery (trexcell)

and FYI, Seidio uses battery cells made from Japan.

I have both the seidio and the hyperion NFC batteries and they both work well for me. Can't complain about either of them. 5 hours plus screen on time usually. Yeah yeah, mod this kernel and underclock/volt that kernal and "I can get that on stock"...well I can't. I like the bigger battery as well.

Went 24.5 hrs before it gave up and shut down - recharged to 100% in about 2 hrs and I'm at 14 hrs running with 66% left - I'm loving this! And as mentioned, I'm preferring the bigger battery/weight feel in my hand, then before. Maybe Samsung should make their phones with bigger batteries and heavier!..lol.

Wondering about this as well

So, is there any NFC-battery somewhere around 2-3k mAh? I'd love to get some more hours in between every recharge (i can barely get home from work before the phone wants to die), but the ~3,8k batteries just makes the phone too bulky for my taste..

I have always heard these will actually output less than that as it takes its charge and moves it to another battery. -Cannot transfer from 1 battery to another 100%

FYI, most of these external battery setups do not recommend charging the external battery while it's on the phone.

Wouldn't touch this with a 10 foot pole. This is similar with a crappy cover put on it.

Yes, after testing was done, it was found that not only is the 4200 hyperion battery (and case) smaller than these, and cheaper, but they have 4200 MAH while these equate to considerably less... depending on when you switch on the external batt case. There is a point that battery can't drop any lower when charging another battery, and you loose some just in the transfer anyway.
the only advantage of this is that you can easily take the phone out and go caseless, for less bulk. but now you are caseless, unless you always carry an extra case around with you.
For me, the hyperion (being smaller than this, cheaper, and more power) was the way to go. and if I wanted to keep slim, but was going camping or something, I would bring an external USB pack (heck i even made a couple: google minyboost).
but hey, if you like it, OP, each to their own.

Trust me, Hyperion Battery isn't more powerful than this. The real 4300 mah battery is Mugen Power batteries. And The Mugen Power Batteries is $99. So Hyperion isn't a good battery. If you think 4300mah battery better than this, you should buy Mugen Power batteries.

No need to hate, just because you got less, and paid more.
Well, then the samsung OEM battery must suck too... because i am getting over twice the on time with my hyperion battery. Over 1 1/2 days, with HEAVY use (over 8 hours of screen time, plus 3 hours of bluetooth, and GPS). Hyperion have been making GOOD quality batteries for years (they used to make them for RC cars, now they do Cell phones too) just because Mugen overcharges, does not make others of lesser quality. Also, hyperion has some of the best customer service i have ever dealt with.
perhaps you should research before you make unfounded claims.

I didn't say bad things to your battery. I'm sure Hyperion batteries good too. But my case isn't bad.

your case may work, he was just saying that you will not get the full charge to convert over as i had said, plus you now have no case for your phone unless you leave it in that 24/7 or carry one around. MUCH simpler (and bigger ACTUAL AVAILABLE battery life) for cheaper with the extended battery. -plus they have 2 different types of cases for the extended battery!
I got wife and I each a 4200mah NFC capable battery and TWO backs for each of us (QCell comes with 1 blue and 1 white back per battery) and TPU cases for them for $5 more each! -and QCell offers a discount for 2+ items!

[Q] Mugen Power 4600mAh battery for S3? Review?

I found this thread where G1_enthusiast reviewed Anker and Seidio batteries for S3, but I also found the 4600mAh battery from Mugen Power earlier than these, and ordered it.
All I head is that cheap batteries are made out of almost expired materials and work for like 200 charge cycles, which explains their price. The expensive ones like Mugen or Seidio work for 400-500 charges, which is better, but would be awesome if some one could review the 4600mAh one. I will post my results later when I receive it, but I don't have experience in doing such tests.

reason why they are not popular is the price tag, i used to think their company is out of japan but in fact they are base out of hong kong (people tend to think china stufff are ****ty). so what make their battery better than anker or hyperion? having say that, i have own their battery before (G2 and SGS2) and they do make battery longer than stock. however i was not into crazy testing at the time. i will not pay 100 bucks for battery again, as long as anker is in bussiness.
seido is the only battery company that is base in texas...thats not to say their factory isnt in china either. they also make quality battery in the past

Well, as I head many times and experienced myself on older phones (I have a 3900mAh from Mugen for Nexus S that works for 1.5 years already) - industry standards cannot produce a good quality battery and sell it for 10$. Those batteries are usually made out of expired materials. The issue here is not just the capacity but the battery life cycle. Cheap batteries have confirmed to last for 100-200 charges, however batteries from Seidio or Mugen last for 400-600 charges, not to say about warranty and safety + NFC support.
Also, for me personally customer support and brand presence is more important than being cheap. If I can afford a phone that costs 800$, I surely can get a good quality battery for a 100$. I will get the battery soon, btw, and will let you know.

I wonder if the Mugen battery will work with the extended cases that are being offered. I got one from Hyperion that I like. Judging by pictures it looks like the Mugen extended door may be a little bigger or designed different.
If the Mugen would fit with the other extended doors and TPU cases I would buy it. I've had great luck with them,

If a cheap extended battery lasts for 200 charges and I charge it every 2 days, it's still going to last over a year. I expect to have a new phone by this time next year if not sooner. So what's the big deal?

Good point, I always try to get the best deal, but for some reason I stopped using ebay batteries long time ago after a couple of duds.

That is why you go for tested name brand but not super expensive. a mugen costs more than 5 times what a hyperion, qcell, etc. costs. but it is very unlikely they will last 5 times as many charges. there is nothing like a fresh battery!

Well, they're always out of stock...I guess they never back back-logs. Anyways, I've received my S3 battery and now I need to calibrate the phone according to their instruction. They say that it's necessary to charge 4-5 times for 8-12 hours before the phone recognizes the new capacity. Does anyone know why?

$100 for a battery! That's more than half what I payed for the phone itself

Why didn't you buy a stand with extra battery that recharges both at the same time and just carry the extra one with you? I did, 18 pounds in amazon.uk. That way there is no extra bulk, and it's much cheaper!

I tend to carry my phone around, that's why. I think that's the sole purpose of having an extended battery in the first place.

Who said anything about not carring it around? I also carry it around, along with the extra battery. At the end of the day i put them both charging.

Yup, when the other extended battery costs less than $30 bucks, why pay much more?

Thanks. Is this the official Samsung extended battery kit? Also, does the S3 fit in this dock when used with either an Incipio or SGP Neo Hybrid case?

This is not the official one, it's Chinese. But in a emergency the extra battery does the trick. The phone won't fit with the case, you have to take it off.
