has anyone tried these cheap 1800 mah chinese batteries from ebay?

http://cgi.ebay.com/2-x-1800mAh-bat...ewItem&pt=PDA_Accessories&hash=item4aa2caf8e2
it doesn't seem anyone has bought any from him yet. I'm wondering how the Android system deals with recharging these, since it is expecting a 1500 mah right? or will it adapt?

Yeah the android system doesn't really care, it measures the battery in percentages.
I've got a cheapo 2000mAH that I picked up for my Hero, it lasts a little longer than the OEM battery. I do notice a difference. When my phones battery is low, I can tell what battery is in it without opening it, just because I know how long I've been off the charger.
They're cheap. You can also find a deal for 2 1500 mAH batteries and a wall charger for $10. I went with that..

I'm buying one because they are red lol.. j/k well for $10 more than the China seller, you get "300mAH" more and this guy is in California so shipping should not take close to a month

I was expecting to be able to offer him $10, but he has that set on auto reject so I just went with the 2x 1500 mAh for $10.

I wonder what brand these batteries actually are? If they are just rebranded Mugen's, then according to batteryboss.org they are worse than OEM 1500mAh.

this seems like a good deal http://cgi.ebay.com/1500mAh-Battery...ewItem&pt=PDA_Accessories&hash=item43a048184b
battery, charger, and case for $13. but its china again

not quite sure what you mean, but ultimately yes, they are all from china. I just thought it was a good deal, but too bad it wasnt shipping from somewhere in the US. I'm not too thrilled to order things from across the world.

I bought the 2x plus charger for $10...They seem to be holding up pretty well, maybe a bit shorter life than the stock one, but if you have three batteries and can rotate through 2 of them while keeping one on the charger, you'll never have to plug your phone in again...I would say BUY BUY BUY, for the price, you can't go wrong, it's worth the standalone charger with a built in usb port.

I am using the 10$ 2x1500ma with the charger... free shipping too. I have only been using one of the Chinese batteries, they are great, they last about, or maybe a little less. I just put the real and the spare one in my wallet... so beast.

I doubt those things are even 1800mAh, they are probably the same 2x1500+Wall Charger $10 deal just a different color/sticker. Its the same exact charger and same exact sticker thats on the 1500mAh ones just it says 1800mAh and the battery color is red.
I purchased the $10 2x1500mAh + Wall Charger bundle about a week ago and have been putting them through their paces ever since, they have been fine for me. About the same as an oem battery, maybe a tiny tiny bit less but nothing really noticeable unless you have OCD like me lol.
I would just spring for the $10 one, search my threads if you need the link. Best of luck.

I know the OP has already purchased the 2x 1500 mah batteries, but I thought I'd add my 2 cents for anyone else thinking about batteries.
I bought the 2x 1500 mah batteries plus charger too. I don't see any difference between them and the OEM battery. I actually do wish they were red so I could use them if I buy the clear battery door that's being discussed in another thread, but not enough to spend twice as much.
We just did a week-long vacation and I bought six batteries for my wife and me to share (coming from the iPhone I went a little crazy). We often switched a battery while out all day, but the only time I needed to use three was when we flew back -- which was a 15 hour ordeal due to a canceled flight. Thank god I had all the battery power I could need without having to resort to $75 external battery packs.

I also bought two of the 1500 mAH batteries, and they seem to work fine. I haven't really noticed much of a difference between the cheap ones and the OEM battery.

For this being only your second post, it sure does look a lot like spam advertisement.

Considering the hellfire conflagration a bad Lipo Battery can cause, I would be nervous about buying cheap knock-offs. If Seido charges $70 for these and someone else charges $4, you gotta wonder what you are getting. I doubt Seido has a $66 markup on their batteries.

it's not something just a deal on a cheap. battery if you want a spare or if like me your charge port is broken and use a few batteries and wall chargers, if you want to spend $9 for the same battery with a back cover go ahead, not Spam just a good deal, show me a better deal for a cheap extended battery. like I said I don't charge the batteries using my phone so these work great, good to charge and leave in the car or plus its always have a normal sized battery in my wallet

TEP covers broken usb ports too. I got a brand new Evo when I took mine in for repair.

I bought my evo used but tried to do the Touchstone mod and messed up sodering or something and now the charging port does not work and the g sensor doesn't work, but I do not miss cord charging I got like 5 batteries and 3 external chargers, that cost me like $30 for all that off cheap ebay sellers, so I always have like 3 batteries always charged and ready to go, don't even miss cord chargers any more

Actually, I wouldn't be surprised if Seidio had that large of markup considering they sell cases with a holster for $50. Which of course is just two pieces of molded plastic with a bit of psuedofelt and rubber finish. And which in my case, started to fall apart within 6 months after purchase. Frankly I don't think Seidio is the slightest bit better than the cheap eBay sellers, they just make a lot more money based on the perception that the charge more so they should be better.

Exactly alot of companies leverage their name so they can sell the same thing as other suppliers at a higher markup. It's good to know that alot of "manufacturers" don't actually make their own product, they actually contract out alot of their products.

Eh... $4, i'll bite.. We'll see how it works out.
Total for this and an external charger was like $7, so not too much money lost.

I purchased a couple things from them already off of ebay. Shipping was a couple days longer than I expected but they are reputable. My battery I got from them also works great...

Finally got around to testing it...
Charged it with the phone off, unplugged and turned it on.
Charged it until indicated green then unplugged then powered down.
Repeated this process four times until icon indicated 100% power.
So far I'm down to 11% and have been going 42 hours and 50 minutes with my normal use (texting, couple calls, light internet use, light gaming).
All in all for $4, great purchase. I was even more so surprised when the eBay seller contacted me and told me it would not fit with the stock battery door (I already knew that personally). They informed me that I would be getting a battery cover I believe, or a full refund.
I didn't mind either, so I just said whatever works.
EDIT:: Checked my inbox today, and they are sending a back cover it looks like.
"Now the battery cover in stock ,and we have send it to you for first time ,this is the tracking#:removed
Would you pls check it later on www.usps.com"
Fun grammar, so we shall see what this holds in store for me.

Are they still for sale?
I made an offer for the same price as the recently accepted offers and got rejected

When I went back to purchase another, they were $104 and some change.
My thoughts are they realized they did not fit the stock EVO and they needed to revamp their posting and or include a battery door.

Do a search on ebay, I found some by a couple different posters.
I can't post links yet but they are about $10

I charge mine with an exteral wall charger just for the battery, and between my two 3500 batteries in can go two days with each battery, but I usually just swap them every morning

I received my 3500mAh chinese battery yesterday and used it until it died. I charged it over night and unplugged it at 6am this morning. When I first pulled it off the charger it immediately dropped 6%, from 100 to 94. At first I was like WTF but I know the USB/AC Charger is notorious for this so I paid it no mind. It's nearly 3pm here and my battery now has 8% life left. Almost 9 hours battery life... something my 1800mAh chinese battery was already able to do. I know I can't expect much from a $8 battery, but I thought it would put out more juice than my stock one at least.... am i missing something?

3500 batteries just take longer to charge, use an external charger or charge with the phone off

Thanks. I didn't think about using the external charger, so hopefully tomorrow's performance will be better than todays. I'm curious though, if the 3500 battery wasn't fully charged, why did it show as 100% before I unplugged it?

So I let my 3500 battery charge for over 12 hours on an external charger. I've had it in my phone for 10minutes now and its already dropped 10%. 0_o

I have seen that on ebay. Some of those deals come from hong kong. Shipping takes forever. Great deal tho I have had one of those knock off extended batterys and it worked like a champ.

Wow! I'm now using one battery while charging the other on the external charger. Shipping took a bit, but I am completely satisfied with the money spent.

Found the same deal for 17 free shipping

That sounds about standard for that package, I think I've seen them for as low as $16 with 2 of everything

I just bought a 2 pack (2 batteries and 2 covers) for $18 with free shipping from Georgia. Hope to get it soon. Should I really expect a short life for this battery?

I bought 2 extra batteries and a wall charger for the battery itself(1). I never run out of juice cuase i always have 2 extra batteries in my car. The items did come from hong kong and was only like 9.7x anyways it was really cheap and works liek a champ as some1 said before. These hong kong items are an american buy

I cannot speak for the extended batteries, but for the Hong Kong knockoffs 1500 mah, in my experience they are just as good as stock.
subscribed for OP's experience with said extendeds

I have 2 sets of extra batts and an extended batt. I rotate every day and it seems to keep the batteries fresh. Plus I don't charge them in my phone so I don't see that loss of 7-8% juice when you unplug.

Thanks for the info. I've got my battery in and used for about 3 days. At first I was worried b/c it drained quick. But I let it drain all the way and then did a full charge and it's running like a champ. I'm going to cycle it one more time as well.
Currently I'm sitting with an uptime of 37 hours and 5 minutes with 35% battery life. This is with my normal use during the work day that consists of texts, some web browsing, phone calls and random games/facebook. Doing this usually requires me to charge my phone at work or it will die pretty soon after being home.
So far It's been a good $20 invested for both my battery and wife's.

I just ordered the Seideio 3500 mah battery from Newegg. I've read nothing but good reviews for that battery, I hope it works out good.

I have been using the "Chi Chi Tech" 2x "1900" mAh batteries & charger from Amazon. I have been using them for about 5 months, swapping them out a couple of times per week and they last just as long as the original 1500mAh battery that came with the EVO, maybe even a little bit longer.
Not a bad deal for $24.

Replacement Battery

Just curious what others have found quality wise with replacement batteries. I've been looking on eBay and have come across a few extremely cheap ones and some mid priced ones as well. Any insight would be appreciated!
Sent from my PC36100 using XDA App

I ordered one of these batteries a few days ago and I'm waiting for it to arrive. I read in another thread that the guy liked it and it worked good so we will see...
Edit: got battery now and so far so good. Way better compared to stock. For the price u can't go wrong. Worst case scenario I'm out 15 bucks if it malfunctions. Fyi using SBC kernel with it.

I've bought several 1800mAh and 1500 mAh aftermarket batteries from eBay and they have out-performed my stock batteries (they're all made in China, anyway). Why pay $40 for one battery at Sprint when you can buy 6-8 from eBay for the same price. Just my 2 cents worth.......

I bought three aftermarket 1500s and an external charger (it was a single purchase) for about $11 with free shipping.
They're definitely cheap and they shipped from Hong Kong. They don't output their temperature or other information that is read by battery monitoring apps, but what I gained was definitely worth the price.
I haven't seen a difference in battery life between my stock battery and my aftermarket batteries. I've used sbc kernels with them without issues, though I rarely charge through the phone.
I couldn't justify spending 4 times the price or more for a replacement or extended battery. Just keep your batteries charged via an external charger & you'll never have to worry about plugging your phone in or cutting back to save battery life.

I would highly recomend seidio they are rated the best as far as listed mah verses actual mah . They sell them online and at bestbuy. Somewhere on this site is a link to a guy who tests a lot of China Japan batteries for actual mah and price per mah. I use seidio 3500 from bestbuy platinum but it cost 69.99. It has 30days warr but it takes almost that much time just to get the phone used to it. Also, its true that that mostly come from the same part of the world but the factory rates them on cell quality and price points them based on this factor. So i would argue that you get what you pay for.
Sent from my PC36100 using Tapatalk

I agree with gentyle completely. I bought a seidio 3500mA battery and a replacement 1500mA from another company and I'll never go with anything else. The 3500 outperformed the others by 3 times even though it should technically have only a bit over doubled them.
Swyped from my synergized best friend

Bought a 3500 mA battery off ebay, for $15, it lasts the entire weekend with moderate use.

Found a great deal on stock batteries and charger!

I just bought these batteries. Im not into extended batteries cause of the added bulk. Its great deal for stock batteries! Not sure if these are authentic Samsung batteries but if hey end up to be generic, they were cheap anyways.

I've bought batteries off eBay that shipped from Hong Kong for my other phone in the past that turned out to be real. At least they worked and lasted just the same as a real one. To this day those batteries still work perfectly fine. They even looked exactly the same so well just have to see

thanks for this! they look good to me and for 12.99 you cant really go wrong. i have some batteries around from my og epic still and I rarely if ever have to use them because my battery life is great now. nut, this does look like a good buyt to me. im tempted to get it just for the charger. i lost mine and cant find it. i have a 4 and a 2 year old boy so theres no telling where it ended up. probably at the dump now...
anyways, good eye for the batteries and charger!

For anyone that may be interested in batteries that are exclusively Samsung OEM: don't purchase these. They are generic. This posting is rather misleading.
Just a few points of thought: Nowhere in the listing does it say they are stock OEM Samsung batteries. The picture is there to throw you off, which has apparently done its job. lol The price and logic don't warrant it being OEM. For the same price as 3 generic batteries, you can get 3 OEM Samsung batteries? Course not, just think about it. Also, it would be illogical of the seller to sell an OEM product so low. The Chinese are known for a lot of things, stupidity is not one of them. lol Lastly, if the batteries end up looking like the picture, does that mean they're OEM? No, because of the above reasons, which are logic and price. The Chinese already produce a legitimate version and/or knockoff version of almost everything one can think of...do you think they aren't capable of copying and creating the same simple logo and sticker onto the generic batteries as there are on the OEM batteries? Of course they can. With ease.
That being said, the generic batteries aren't exactly garbage. They're just fine and have the potential of working just as good as OEM batteries. Though there are some lemons here and there that don't work up to par, and some that don't work at all. I just wouldn't expect to get a Samsung OEM product.
Coincidentally, I myself bought another set of 3 generic 1800mAh batteries + 1 battery wall charger from eBay today for $9.99 + free shipping and should have them in less than a week thanks to buying from a U.S. seller.
AMERICA.
P.S. Sorry, but I gotta vent (and inform) about this...there's a seller from China on eBay with a poor feedback rating selling the highly popular Samsung 32GB MicroSD Class 10 cards for roughly $15 each (they normally sell for between $50 to $75 and still have counterfeits among them), and some moe-rons snatched up about 400 of them in about 3 days time. Really, people? With the ridiculous, rampant amount of fake microSD cards on the internet market, you're actually going to believe a Chinese seller with a poor feedback rating selling "OEM" Samsung newest generation microSD cards for $15?? Common sense isn't so common. Bottomline: you get what you pay for. OK I'm done venting.

i ended up picking up a set of 3 1800 mah batteries and a charger for 13 bucks. tethering 4g really does a number on my battery (guess its the wifi + wimax being on at the same time) and it would be nice to swap these out when needed.
One thing im concerned about, do these batteries heat up with constant use? ive felt the stock battery go up to 42 degrees and i think any warmer than this may end up damaging my phone.

I would bet my middle testicle that those things are as fake as a chola's eyebrows.

dont really care about them being fake, just dont want these Chinese?? cells overheating and damaging my phone.
for thirteen bucks shipped i didnt really expect oem batteries, just something to use/drain/swap while tethering

I bought these.. 3 and external charger. I don't regret it one bit. I could careless about battery drain now. I can now use my phone and enjoy full usage without having to worry. I highly recommend it. Although it will take a month to come in. If you are even slightly considering it, I say go for it.

thanks for your reply, ever have issues with the ebay batteries overheating/warming up?

You lie. YOU LIEEE!
Links or it didn't happen.
I'm gonna order some from HK because I can't find any in the US.

I switch between the 4 all the time (1 OEM and 3 generic). The three generics are numbered so I can keep track of them. I've had them since mid November, and I haven't noticed any difference in battery life relative to the stock battery.
I haven't had an overheating issues with any of the batteries either.

i have generic batteries as well and at first thought they were the same capacity as the OEM stock battery but that's only from 100 down to 40%. with the generic batteries, once i get to 40% if i reboot the phone it'll drop down DRASTICALLY to ~10%.

well, the seller in the ebay link, has almost 11000 sales, and a 99.4% positive reviews, so I would think its safe to buy from him..I am sure they are not "real" samsung batteries but, hell, for 13 bucks for 3 batteries and a charger, who cares!

China makes the best lipo batteries on earth. They also probably make the worst. It's a tossup. Luckily there is a good way to tell sometimes. The Chinese are more capitalist than we are now, so if a company in China makes good batteries they will put their name on them. If they make good product and only sell good product, they will gain notoriety and get to increase their prices to cash in on it.
So on these no-name batteries, either take the chance or buy Korean from a trusted retailer. Wot wah!

Had nothing but bad experiences buying batteries from Ebay, then again last time I did it was for my oldschool Motorola RAZR.

Just wanted to report back on the ebay batteries. So far so good, though they are definitely not as good as my stock battery. Good for swapping out when tethering etc. They do heat up with use, the max i saw while tethering is 47c. At these temps its unlikely they will last long, but for ~4 bucks each i guess they are replaceable.
The bundled charger puts out 5.2v at 800mah though it does have an annoying blue led that's always on while plugged in(black duct tape took care of this for me). Would have been nice if they bundled a usb cable, the one i had laying around works just fine.
Overall I had a great experience with the ebay seller who shipped China post->USPS, took about 10 business days.

Well I ordered some off ebay on the 12th of Feb. China post tracking says it just passed through a sort facility. Well, now I remember why I stopped using ebay 10 years ago. I miss when it was just stuff that fell off the back of a truck and people selling their used stuff. Now it's just chinese people dropshipping stuff that takes them two weeks to locate before they actually ship it. *fart*

Review after 30 days of rotated use:
These batteries are cheap. Very cheap, at best I would estimate 1500mAh, and they only go downhill from there. Now I'm lucky to last 7 hours with streaming radio. I would estimate I'm down to 1-1200mAh after less than 10 charge cycles.
I also broke the tabs on the charger inserting a battery too forcibly, but easily fixed with ABS cement.
However, I only bought them for streaming, tethering and to keep cycle count on OEM battery down, but it may not be worth it to you given the terrible life cycle.
