BST-41 battery on Ebay

I noticed recently that there are some Ebay sellers selling BST-41 batteries at very low prices. All of them seem to be from Hong Kong or China.
I got this feeling that they are all fakes. This is too good to be true right?
Anyone who got one care to share your experience?

Personally I'd avoid batteries from third parties that are "incredibly" cheap.
Make sure the quality of these batteries are well known. (comments, forums, other users, etc.)
I'm not telling you to stay away from them, but to keep an extra eye open and make a bit of research on the manufacturer before you jump on.
These types of batteries should be rigorously controlled during manufacture, and I bet these cheap batteries aren't so well controlled during the manufacturing process.
Sometimes even some chemical components or processes are skipped to keep the manufacturing costs down.
Risk of third party batteries to catch fire or even explode, due to the lack of quality, are bigger.
I've seen a few battery fires myself, and every time it was due to a "low quality third party battery".
Search the net on "lithium-ion fire" and you might get a glimpse

Just bought a pair, and they don't work.
When you get them, they are charged to around 45-50% and when you put them in your phone, they don't charge at all...
Don't waste your money, even if they are cheap.
I gave around 15$ for the batteries...

Thanks for the replies. Amazon.com it is, then.

I got a what was advertised as a genuine battery off ebay from a uk supplier
and while it works fine in my old x1 it's a tiny bit too short to push itself up enough to reach the battery contacts. Easily remedied though by gluing sone thin plastic packaging to the base.
Still not sure if this is a fake or a factory second as it holds charge fine and has the correct markings. It cost around 10 gbp

I got a cheap pair from ebay that were labeled as Sony SBT-41 batteries, but of coarse the labels were fake. Do a google search on fake Sony SBT- 41 labels.
Also, apparently, cheap batteries can be dangerous

Will these make me go faster?

I have read that before..are really that good ?

Whats the different between a 1550 mAh Mugen Power battery for 30$ and a random 1550 mAh battery from eBay for 10$?

some ebay sellers sells unbranded or fake batteries (would say 1800mah but is actually 1300 etc..), usually with no return/exchange policies specially the cheap ones like 3 pcs for 10$.
mugen pretty much you get what you pay for.

Man that's nice

I don't have issues with the stuff I got from them. I saw on their facebook page that they change the batteries if they're working...which is good and they have 1 year warranty on stuff. So far I'm going with them. Got 2 days on average usage on my Nexus

looks like I found the answer to my question. will check them out, thanks!

Personally for me the big difference is their brand presence across all available customer service channels (twitter, facebook, email, phone etc...) and high quality. I'm using my 4th battery from Mugen at the moment and totally happy with it and with their service.
Also I received a reply from their rep that actually makes sense - they say that their price allows them to give all the listed services to the customers, and it is simply not possible to make a good battery for 10$ using top technology and aftersales support.
Anyways, there's many info here about them, you can research a little.

While it would be nice to have an extended battery, I wouldn't want to make that change because it would make my phone heavier and clunkier with the extended battery backdoor. Another big downside is that my case wouldn't fit anymore. To solve my own battery-life issues I keep a Duracell Powerhouse with me when I know that I'm going to need extra juice.

You can always choose a slim extended battery that fits your original phone socket and does not require an extra back.

I have heard that the "extended batteries" that are the same size as stock are counterfeit in the sense that they don't actually offer more capacity. Lots of scams and shady companies around extended batteries...

It's 'Moogin' baby. Seriously, this is just a name tag being placed on the battery. It looks too ugly for me to put it on my Skyrocket.

will check them out, thanks!

Mugen Power batteries are great if you can afford the entrance fee. Yeah, it's not some cheap knockoff from Ebay, but the quality and battery life is worth it. I recommend them. Here's a review I did of the extended batteries on the T-Mobile G2 if anyone's interested

Plus one for Mugen from my side. I've been recommending them for quite a long time now. Some experience to share: ordered a battery from them a month ago and nothing got delivered. I contacted them on facebook, and it turned out that the post lost my parcel...I was a little nervous cuz there was more than 150$ in it, but Mugen replaced all of it in a matter of days. Not just great batteries but awesome support as well.

Very good battery. Works flawlessly.

are mugen batteries available in india?

Replacement battery (Original with NFC)

Hi!
I was wondering where I could buy even more batteries for my Galaxy S3.
I did find a battery on ebay for $7 (going to buy 3 or more), but was wondering where I could get it cheaper with free shipping.
I doubt it, but would like to check this forum first
Link on ebay for $7:

Thanks on beforehand,

That is really cheap. I also am going to guess that it is not full on OEM. The one I ordered was a little different. It said Samsung, but it wasn't. I haven't tried NFC yet.

As far as I can see, the battery doesn't have NFC included in that battery. I think the original battery with NFC cost about $30 if I'm not totally wrong?

I can't see ebay links at work. I was just guessing you were buying from someone like who I purchased from. If it is OEM it has to have NFC. I would go with Anker if I didn't want NFC. They make the best Non-OEM batteries that I've used, although I've heard good things from Hyperion too.

Avoid fake chinese crap
I'm looking for a real samsung battery too, but I wouldn't trust any seller on ebay claiming them to be genuine. Most are from china, and I'd have to guess 99.9% of those would be copies. Amazon lists one as genuine for $25, which sounds about right. but again, I have no clue. Personally I'd like to see and buy one in a local B&M store. unless I knew for a fact I'd be buying a real samsung battery.
I tried a "4200mah" chinese battery, twice as thick, new bigger battery door, etc... CRAP CRAP CRAP. Doesn't even last AS LONG as the factory 2100mah thin battery :crying: JUNK JUNK JUNK.

Today I got 3 batteries from ebay - bought for a very cheap price, less than 15$ in total.
The battery didn't fit properly, I found it hard to get the battery back out. It also said that the battery had NFC, but no.
Seems like it wasn't even Samsung battery, which I tought it was until I saw the label they'd glue to the battery, all the batteries also shared the same S/N: AA1C505BS/2-B.
I haven't been able to test out the actual battery lifetime on the cheap batteries, since I won't be using them anyway because I wan't NFC capabilities.
Stay away from cheap batteries, best way to get a quality product is to actually put some more bucks into the product. Get the "real thing" that works the way it's supposed to do.

Extended Battery Brands

Hey guys,
I was considering purchasing an Extended Battery for my Optimus 2X, and found the many various brands available. The best one's I've found after quite a bit of reading include Mugen and Seidio. The problem is, Seidio doesn't offer the largest capacity (if I am going to do this, I'm going to max the capacity out), and Mugen is at about $100 for the 4500mAH battery, which is quite a bit. After reading the optimus 2x dedicated accessories forum, I came acrosz a recent thread about a 5000mAh MPJ Battery, which according to the post, works great, at am affordable price of $30. On the site, the 3 reviews are dated the exact same day, and in the product picture, battery is spelt incorrectly. My question is, can these brands be trusted, even after what appear to be a few good reviews? Thanks.

Just to make it more clear, Do you think that MPJ Batteries are reliable? Has anyone used them?

To be honest, I never even heard of them. Mugen, Seidio, Anker, RavPower, Zerolemon, and Hyperion are the better known brands you can trust. Everything else, I'm not so sure about. It could be an OK battery, but from my experience a lot of the unknown brands put a capacity sticker on it which is exaggerated, and they have questionable quality. We just recently had a discussion in Note 2 section where someone spoke very highly of Gorilla batteries, read a lot of positive reviews, and they even had a fancy website. Once that guy actually got it - it was a disappointment which exaggerated capacity.
Also, keep in mind, Mugen and Seidio makes their own batteries, so they charge a lot more for it. Others re-branded products from HK and just have a tight quality control and offer extended warranty (like Anker has 18 month warranty), so they charger a lot less for their batteries.
I heard only good things about Muugen quality, but it's way too overpriced. I have used INNOCELL from Seidio, actually reviewed it for Note 2. It was a good battery, but still overpriced. Anker, RavPower and Hyperion would be the choice for best price/performance/value.

Thank you so much for your reply. It seems that for the maximum size available (approx. 4500mah), Mugen is the only way to go for $70 at Amazon. I will think about whether or not to make the purchase. Thanks again.

don't go with hyperion, they are known to overstate their true battery capacity. i believe vectron (a guru on this forum) actually proved this.

Guru is a big word, but thanks anyway for kind words
I believe I pointed out to other threads on XDA where people removed the label off Hyperion battery to reveal the actual value, smaller than advertised. They make ok batteries, but sometime have a shady labeling to "boost" their capacity

Battery Case - Too good to be true?

I pre-ordered a battery case on Amazon, but it just seems too good to be true. I cannot see how they can fit a battery that size into that case for that price.
https://www.amazon.com/Rechargeable-External-Portable-Protective-Charging/dp/B06Y63HPCL
5200mAh
$26.99
Very slim and slick looking
Any thoughts? Should I cancel the pre-order or is Amazon reliable when in helping to avoid fraud?

I just saw this, it's not that expensive, please post IF you get it with pictures as to how thick, hand feel, and so on. I'd be very interested in it if it's not going to make my device look like a brick from the 90s.
There's about 5 pages of questions now and there's a LOT of discrepancy between what the "description" states and what the answers from the seller state:
Description: has a kickstand
Seller answer: has not kickstand
Seller keeps saying you can wirelessly charge with this case in the questions, I WANT to know how that will work. I may order this JUST to see if any of the hype is true

It looks monstrously big for the s8 plus

Update: They increased the price from $26.99 to $39.99. That sounds more realistic now. Also the picture is different and it looks a bit more clunky than the original images. Once I get it I will post pictures of it and give a review.

No way that's 5500 is such a slim case, this case is 5500mah look at that fatty https://www.amazon.com/dp/B06ZXYRCKM/ref=psdc_7073960011_t1_B06Y63HPCL

Okay, holy mother of crap, that thing is huge.

I just could never do a case that big...not with phones this size. Holy crap i can't imagine that in my pocket.

Please post feedback when you get it.
It may not be the slickest case but if it does add 5000mAh then it can be a backup plan for a weekend outdoors. There are times when having a battrey pack makes it much more clunky than a battery case, no matter how bigger it makes the phone.

So, let's see what could possibly go wrong:
Third-party company that no one has ever heard of making a battery case that doesn't even agree with its own pictures of the product/product description
Will it overheat? No, why would you think that?
Will it make your phone burst into flames? Why would that be an issue?
Will it actually work as stated? Sure, so many of the cheap knockoff battery cases work just great.
Please do post how this works out for you. Also, make sure you have a spare device from which to call 911 (or 999 depending on your location)

Best power case would be zerolemon when it comes out

Just ordered this one from Amazon. It's in stock and I will get it monday and let you know how it is.
https://www.amazon.com/ALCLAP-Porta...-catcorr&keywords=Galaxy+S8+Plus+Battery+Case

I guess there's one manufacturer that makes all of these cheap power cases for any brand. The price is great but I wouldn't risk an S8+ for a 50$ price difference. And everything above 3000 mAh will add too much bulk. Don't bother and think that it won't look like a brick. I was prepared to order the Mophie but got insulted by their bad marketing moves. Articles all over the web about the release of the legendarry Juice Pack, and all I got was a coming soon warning! No Thanks. As djhulk2 said I would go with the ZeroLemon or the I-blades. Remember these are brands, plus the I-blades adds extra memory, a platform for other modules and Military Grade Certificate.

They should have different size of batteries...maybe 1000mAh, a 2000mAh, and 3000mA

There are numerous choices out there (just from a google search using the terms S8+ battery cases):
https://powerpluscases.com/collecti...-galaxy-s8-plus-battery-extender-case-5500mah
https://i-blades.com/products/galaxy-s8-plus-case-battery-life-memory
https://www.amazon.com/ICONIC-Portable-External-Protective-Charging/dp/B06ZZB2QYC (has a code of 2RADT4V8 for $10 off making the price about $30, know NOTHING about this battery, BGR is hyping it)
https://www.amazon.com/gp/product/B06ZZB2QYC/ (another case with a code HC7VJ26M for more of a discount, again another site is promoting this)
https://www.amazon.com/Rechargeable-External-Portable-Protective-Kickstand/dp/B06Y63HPCL/ref=sr_1_5 (no idea about this)
https://www.amazon.com/s/ref=nb_sb_...+battery+case&rh=i:aps,k:s8+plus+battery+case (a generic search for s8 Plus battery case on amazon)
And that was about 10 minutes worth of looking. There are PLENTY of options out there, just got to be willing to look.
