Beware of bad batteries for Samsung S2 on DX.com - Galaxy S II Accessories

I bought two batteries on DX and they both are really bad. Both work ok for first two months then go really bad really fast. I even suspect that almost all of the reviews are faked.
My suggestion is don't but battery under 10$, they are usually worthless very soon and just a waste of money.
"I'm not ritch enought to buy cheap stuff" is my new moto
These are two batteries that I bought:

Cheaper 2700mAh battery on DealExtreme

This showed up today for $14.60:
http://www.dealextreme.com/details.dx/sku.41890
Looks kinda ugly.
If you're not familiar with DealExtreme, be prepared to wait a month or more for your item - they all ship from China. But the shipping's built into the price.

Plus usually their stuff is not to bad..
This had me a little worried:
- Replaces your broken or damaged original palm pre battery
with most chinese batteries not even being 70% of their claimed mah, looks like alot of extra bulk for very little battery life. an extra 300-400mah MAYBE.
Looks like the same one sold by boxwave.com which is pretty good company. I've ordered stuff from boxwave before.

Well for getting batteries, i never deal with dealextreme, as its not reliable. I usually order my electronic accessories so as batteries with Chinabuye, reliable and well made quality. They are online store from China, i find i get all latest hitech gadgets and their accessories at best rate. My batteries working so far so good! Worth it!!
why are all the larger batteries LiPo?
after dealing with them in airsoft there is no way i would put one of these in my pocket.
and in the fact that they are cheap chinese batteries and you have a recipe for napalm to your genitals.

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

batteries for gsm model...should i trust this

Seller has excellent reviews, although ive been burned by knock off batteries that claim to have more juice, and last half as long
http://www.ebay.ca/itm/2-X-Battery-...ccessories&hash=item41611a66cd#ht_4575wt_1396
i dont expect better battery life, ijust hope it lasts as long as my oem
any feedback?
Thanks !
by the way, they are ANDIDA batteries, reviews seem decent, but any other feedback from members here would be great.
Like i said, a spare OEM battery seems to be 50$
I just want one that will last as long, without being extended or making phone thicker

I like his ad: "Avoid the cheap Unbranded batteries!" It should add: "And buy the cheap supposedly branded ones instead."
Buy cheap, get cheap. You get what you pay for. If it seems to be too good to be true it usually is. And all other similar comments.
I'm sure it would hold you over in an emergency but no matter how you slice it, it's still a cheap Chinese knock-off battery.
As for feedback it's usually pretty meaningless because a few weeks later if it failed or gave poor service the "good" feedback for fast delivery has already been left. I had that happen to me on a cheap Nikon battery. It barely held a charge after a month and I already had left + feedback. The seller would take it back but to mail a $8 battery back to China was a waste of time and would cost almost $6. I ended up spending $40 on a real one which ended up costing me $48 because the cheap one had to be tossed out.
true, but these are ANDIDA batteries, reviews on XDA say not really as good as advertised, but all pretty much say better than oem
I think i will give these a try, like i said, im happy if it performs like a 1750mAH, and they are not 2-3$ ones, still 15$
if it's a third party brand battery, i'll go for goki and momax, i have always trusted them, and they dont make batteries with high battery capacity like 3000mAh with the size of a standard battery, it's not always possible, instead , their battery do last long and is rather good quality.
in ebay search for momax i9250, there are plenty, the power are 1650mAh.
if you want comments on them, here is a link on the momax i9000 extended battery, forget the comment on the case, and read comment on the batteries.

OEM battery on eBay

Any chance these are legit OEM batteries? Two OEM batteries for $16 seems too good to be true.

It is too good to be true. EBay is crawling with fake "OEM" batteries with a sticker that looks exactly the same as the real one. Makes it almost impossible to tell from a pic. If you want a "real" OEM battery, you need to get it from a known good seller. Shimshop on EBay sounds reliable from reports here. There's also Expansys, they likely have the real deal. The pricing I've seen is about $30/per for the real ones. Much cheaper and it's probably a fake.
i was thinking these: http://www.ebay.com/itm/Original-OE...ccessories&hash=item2a18a7b669#ht_4442wt_1247
looks legit but who knows.
Also newegg had some but I don't see them now.
I've been using the bargain-basement eBay China batteries in everything from DSLRs to cell phones for like 7 years. They never work quite as well as OEM but at 10% of the price for 90% of the performance I don't care.

Its funny you posted this. I ordered 3 of them with charger and got them a few days ago. They are not OEM however they actually work pretty well. I sent seller email before i bought them and was told in his own words they are OEM samsung batteries.. I did this so when they were delivered i would have proof that seller was stating the fact they were OEM... I knew however for 14$ there was no way they would be real. This way when I contacted seller to complain i would have a leg to stand on. I sent him and email stating that they were fake and that I wanted to know what they were going to do about it and 1 hour later a paypal refund for the full amount was issued. These guys know they are selling fake stuff however unless you have a trained eye and know what you are looking for it would pass as an OEM product. For the price.... They are good batteries...lol.. To be honest i would have gladly paid the money if the seller would have come clean on the matter.. I will take pictures and post them when i get a chance..hope this helps....cheers
I took pic of all 3 with charger and a pic with a real OEM next to the eBay battery...can you tell the difference? lol... Oh and pics were taken with my Nexus so please excuse the quality...
The "original" ones on eBay IMO are fakes. Also the typeface used on the label definitely doesn't match the OEM battery that comes with the phone. I would avoid them and buy from a trusted vendor like Expansys or Handtec.
If you email the sellers of these real, but fake batteries, they will quickly say they made a mistake posting and the batteries are not genuine... I hate when sellers play games like that.
We should all mass-purchase these "original batteries" and demand refunds at the sellers expense, just to teach them a lesson. It's not right to knowingly scam the public.

Agreed. Usually you won't go wrong if the seller has included "genuine" in the listing. Be careful when they don't include that word. That's common ebay sense.

I go to Shenzhen and HK regularly, and I've been in the shanzhai/jiamao markets there and they have booths with blank batteries and the stickers that look almost exactly like all the major brands, they will make you up 100 or 50 or any qty you like on the spot. When they sell a counterfeit battery they always include a charger.....guess why? They caution you not to charge that counterfeit battery in your phone, it might explode or catch fire!
So they always sell the charger with the battery.
NO WAY would I put one of those P.O.S. in my phone.
They are tempting though.

Yeah ..i was pretty sure when I bought them that they were fakes so when I received them I was not so surprised.. I did however get 3 batteries and a charger for free..lol...They are actually pretty good...They don't heat up and seem to last as long as the original. They are about 90% as good as the OEM as far as discharge times. Overall I am quite happy with them...And for the price I can't go wrong..
Damn I wish I had seen this the only way I knew was that it was fake was the NFC didn't work.

I've been using ebay batteries in my G2 for a long time. For the price I'd say they are worth it. I had a 2200mah evo 4g battery from ebay in my G2 for over a year and I just recently had to replace it because it wasn't holding a charge quite as long as it used to. When I first got it, it would easily last a day, which was something the stock htc battery couldn't do. Now I have an extended 3500mah battery I paid only 6 dollars for and I can get 3 days off of a charge. I have a 2300mah battery on order for the nexus, I'll make a review thread and let you guys know how it does.

WTF?! Anker 1900mAh battery now $48 instead of $10?

What's up with the price change? Is there anything justifying the 470% price increase?????
Other than greed, I mean...
Anker battery, sold by 'authorized seller' on eBay; not even ten bucks:
http://www.ebay.ca/itm/Anker-1900mAh-Battery-Samsung-Galaxy-S2-II-i9100-/220813288199
Same battery sold by same seller, much MUCH more expensive now:
http://www.ebay.ca/itm/Anker-1900mAh-Battery-for-Samsung-Galaxy-S2-II-i9100-/330747106855
What's up with that? is it because the I9100 will be "phased out" or something? Isn't there an installed customer base huge enough for these guys to continue selling their batteries at an affordable price? I'm flabbergasted.....
-=-=-=-=-=-= Edit:
After having looked around a bit, to my great surprise, I was able to find this at $9 on Amazon.ca. I was VERY surprised since we, in Canada, rarely get the same deals as in the US... we always get milked with more expensive products, even of our dollar is at par with the US dollar. But this time, the price was the same.
Now the funny thing is, the Amazon.com and .ca seller is the SAME as on eBay; so he sells these babies $47 on eBay and less than ten bucks on Amazon. I do not understand it one bit....
wanted to buy this battery about a week or 2 ago and saw those prices on ebay, no idea why it increased that much so would like to hear if someone know

Your best bet is now Amazon.com or Amazon.ca... If you are luckily to be in the USA or Canada.
Other than that, the eBay prices are absolutely grotesque... :-\
NEW ROM will arrive people will buy NEW BATTERY instead of changing phone ! (It`s a 2 year old phone so battery will not last as new)
It's back down to $12 now, but I'd say they were low on stock so they jacked up the price for the last one or two units to avoid running out. Many online sellers do this for some reason, I guess selling out looks bad.
