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

they are all from china

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.

Do yourself a favor guys....

Stop the debacle and concern on whether or not the 1700mah, 1600mah 1500mah blah blah blah batteries are better than stock.. I have a LOT of experience with Li-Po and Li-Ion batteries (cell phones use Li-Ion technology) and I can tell you WITHOUT a doubt that all these knock off companies are full of SH^* trying to say there batteries are of a higher capacity than the stock battery while staying the same size. Although it is possible to cram more mah into the same size package with li-ion batteries it is VERY unlikely to be able to do so with the current technology out right now. Most of these companies rate their mah on a different scale and actually will pull the battery to a lower voltage to justify their claims when it dosent matter because cell phones have a safety feature that has to shut the phone down at the specified voltage to prevent fires. Yes fires, Li-Ion has a fire risk if it is depleted all the way, not the same risk as a Li-Po battery but a risk just the same. HTC has a separate department that deals specifically with batteries and I can assure you they know and use the most up-to-date batteries they can get their hands on for these devices. There is nothing for them to gain by using inferior batteries in our phone. Those that have purchased the seidio 1600 extended battery and claim to have a better life on the phone are under a placebo effect. If you are just purchasing this "Extended" battery as a spare than buy all means go right ahead but dont expect a miraculous two hours extra from it because it is of lesser quality than the stock battery. I have hundreds of dollars in battery testing and logging equipment and If you guys dont believe me i will run some tests on the stock vs. whichever battery you'd like me too and post the data for all to see, but Ive been down this road before with htc phones and have always come up with the same conclusion......The aftermarket "Extended" batteries actually have less mah's than their stock counterparts.
Of course Im not referring to the htc extended battery in this post, its obviously pushing more mah's with its monstrous size, lol.
....just sayin..

Oh' and to elaborate because Ive also read some concerns over the length of time for charging the thunderbolt (which does seem lengthy I will admit).
Since our phone has such a hard time time keeping up with a normal days use I believe what htc has done is given the battery a longer "saturation charge" for the battery to completely charge before it completes the charge cycle.
Li-ion batteries are charged on a 3 cycle charge system and stage two is what is considered the saturation cycle where the battery may sit at a relatively static voltage for a period of time to saturate the cells with current to top off the charge, some cell phones skimp on this step to give the phone a fast charge time which is termed "charge-and-run" and people assume the device has been adequately charged when it has not. For an adequate "FULL" charge without harming the battery or affecting battery life, typically li-ion batteries take approx. 3-4 hours.

So the 3 batteries I got for 12$ on ebay ARE paperweights?

No. The two I bought for $44 are. How much do oem batteries cost?

I wouldnt go that far, I doubt any of the batteries are "paperweights" yet. Im just making the point that the claims of higher capacity are unfounded and the cheap knock-offs are of lesser quality. Also check where the batteries are made. Good quality Li-ion cells come from Japan.
One thing to note with the cheapies is the temp while charging or under heavy use. Get a temp monitor app and compare between the stock and your aftermarket batteries, they will probably run hotter. Unfortunately I dont have any other batteries to test for you guys other than the stock OEM battery otherwise I would. If I pick any up Ill cycle the stock vs. aftermarket and post the data log between the two.
Also I didnt mean the "fire" comment to worry anyone, Li-ion batteries have protection curcuit that will render the battery useless and unserviceable if the cell reaches a voltage of 2.70v or lower which is where the chemistry of li-ion becomes unstable.

I'll ship your one of the two 1700 when I get it if you wanna test it and post results. Just ask that you ship it back after your done.

ha, I bought the same ones you did.
I didn't expect them to be as good as the 1400 mAh battery that comes with the phone. I just wanted to have a spare battery available in case I'm traveling and watching movies or something (on a plane). Even though it says it's 1500 mAh, I expect them to be more around 1200 - 1400 mAh.

Check this website for some information on similar battery testing.

I used their results when I purchased the Seido 3500 for my Evo.

I've used Chinese batteries every chance I get. They do work. From an Eris to the Dinc. 3500mah. Never had a problem. Emails and games etc. I bought the extended battery along with the Tbolt. Just don't like the hump on the back. I'm on eBay every night waiting for the Chinese to strike with a extended battery. At least a Better extended back cover. For $10.99 free shipping ill wait 2 weeks for it. F%$% what u heard their cheap batteries work.

If you do I recommend you buy the 1500 MyTouch4G batteries from ChiChi's htcexpress or their store on amazon. They should be the same a the 1700 Thunderbolt batteries and $20 cheaper.

When I get around to ordering up the batteries Ill post a chart like that on a seperate thread for our phone. I have some pretty sophisticated logging equipment. It shows the temp, charge capacity, voltage, mah, cell balance and health in an easy to read graph.
Im not a battery nerd but I used to be into RC helicopters BIG time and when you have a $5000.00 helicopter that can kill someone its just normal practice to have the equipment to check your $800 batteries so they dont fail 80 feet in the air and blow up or decapitate someone, lol

Heres a video of one of my helicopters (Trex 700 electric) , this one uses two 6s 5000mah li-po batteries and each one costs over $300 and they only last 8 minutes before there dead The video isnt of me however, I need a video camera to post mine but the helicopter is identical for the most part.

(speaking from g1, nexus, and g2 experience only)
i've bought extended batteries for phones for less than $15 each all in the 2400 to 3600 mah range. they last 2-3 days with normal use. the oldest one is 3 years old (g1) and still performs like new.
iirc the seller was based in hongkong.
just saying.

the htc extended battery
personally of all the batteries i have tried this is by far the best one until sedio has an 3500mah then i will be getting that i think

[Q] Anker 1900 mah vs Anker 2300 mah battery?

Good day all out of thses two 1900 mah & 2300 mah which is better vaule for money and is the Anker 2300 mah battery really that slim it still fits with the orginal SG2 battery cover? In any case I was thinking of getting the 2300 mah battery as it got good reviews.
Thanks to all.

both anker 2300mah batteries but they look different!!!:

http://www.ebay.com.au/itm/2x-2300m...AU_MobilePhoneAccessories&hash=item4cfaa21158
also the anker 1900mah looks different and more genuine:
http://www.ebay.com.au/itm/2x-Anker...565191?pt=PDA_Accessories&hash=item4aacda4387
i dont know what to choose im stuck same as you.. i want the extra 400mah but will i get the extra 400mah or will i get even less than 1900mah !!!

Yes Im aware of the other batteries same manufacture as I see it.
Just wanted to know which is better the 1900 has good all round reviews as for the 2300 not heard to much on this one myself, more so some site claim it (2330maH) still fits with orginal batter cover .

I'd personally go with the 1900mah ones.
Every battery with more than 1900mah while still stock size I've seen reviewed has actually had less than mah than the stock battery.

Thanks for your input D3 like I said there not much (or Im looking wrong places on net) on reviews on the 2330maH battery, at under 10 euro/pound I may just order the 1900maH one still no rush.

Do you actually believe some company managed to stuff more capacity into a battery without increasing its size? There's a reason samsung's 2000mah battery is thicker, don't be fooled by the rating on a non-oem battery, its fake all the time http://batteryboss.org/

Then im sure samsung which is one of the largest electronics manufacturer in the world would of figured this out by now, not some unknown anker company. Don't be fooled by a label on a battery, even the popular seido/mugen batteries fall short of their ratings.

anker is not an unknown battery company... they are known for their high quality batteries...
and its proven multiple times that the 1900mah battery is 1900 and even 2000 for some ppl....
i do think the other one is fake though (the 2300 one)
Im thinking of getting the 1900 battery together with the anker charging dock you got a 2pound discount!

Went for the 1900mah placed order thanks to all

can someone tell me if this is the real genuine anker 1900mah battery that everyone is getting here on xda?

As per the photo yes but if you have not done business with said dealer drop them a line to find out if these are genuine anker batts.
This way you'll have digital proof if they turn out to be fakes and you can take it up with ebay there after...

3500 mah battery coming soon?

I'm hoping to get a bigger battery for this phone as I have to charge it twice a day w regular use. And this phone falls out of my hand too easily so it could use more weight and thickness.... anyone know of any batteries other than the 2100 mah? Its not worth adding only 400 mah so I'd rather get the 3500 if it comes out.

Check the Samsung website, I saw a higher capacity battery with accompanying back plate there. eBay may have one too.

There are only two batteries, the stock 1850mAh, and the extended 2100mAh (which is what OP is talking about). I agree, i would like to see something better than just a 250mAh increase (and i got big hands, so i would enjoy the thicker profile)
EDIT: there are only two batteries from samsung; i guess you can find a 3rd party 3500 online if you are willing to trust it in your $700 device (i wonder if 3rd party batteries are covered under warranty)

QCell galaxy nexus 2050mAh Slim battery review

How much was it?

I just "love" these so called reviews ... no photos, no real tests, no real comparisons ...

Thanks! I order myself two of the single batteries here. The original alone is just not enough to run the phone. Seems like they did have the two batteries plus a charger before but that sold out.

If anyone has any idea where I can buy one of these from outside the US, please let me know ^^. I live in France so anywhere that can deliver to Europe really. Thanks

Hmm, I wish I would have known about this before, I would have tried it out. I just received the official Samsung 2000mAh battery and cover from SK. Cost me like $45 on ebay.
edit: although I note the qcell battery does not appear to support NFC...

These batteries are quite good. The charger is very handy in charging up the spares. Highly recommend this

I've bought a bunch of 3rd party batteries for my previous phones (Nexus One, Sensation), and have found that they're pretty much all crap and any perceived gains are simply psychological. Actual batteries mAh ratings are often significantly exaggerated on the product labeling, this can easily be determined by peeling off the label and looking for serial and model numbers printed on the metal battery casing. Googleing these numbers brings up product data sheets from manufacturers in China with the actual mAh rating.
I now only buy OEM batteries as I think it's the only way of ensuring your getting what you think you are. Think of it this way, if Samsung could pack more mAh into a specific size, they probably would. The size of a battery is limited by the battery technology, so if you calculate the mAh/gram density of the OEM battery I would use that as a guideline. 3rd party batteries advertising densities higher than that are probably exaggerating the actual capacity.

Jim, completely agree, and have usually found non-OEM batteries to be total crap, however it's possible to find some that aren't. I bought some PowerGen batteries for my Nexus One about a year ago and they've given me performance on par with the OEM battery. I made that purchase based on positive reviews and since they only cost about $10 (IIRC), way cheaper than OEM, it was a good risk and deal. Worked for me. I'm hoping the QCell batteries will be the same, but haven't seen enough positive reviews to know yet...

I don't want to come off as a completely cynic (which I will), but the two people talking about these QCell batteries are named "ckang008" and "awong12." The latter of the two has 3 total posts on XDA, and "ckang" has a handful of posts since registering this past January (55 total) talking up these QCell batteries for all different devices. Again, they could both be very real people, but this thread to me seems like a bit of a hoax.
But if this thread in fact legit, I do agree with Jim and GPSRider as I have similar experiences with OEM vs non-OEM batteries in the past.

Any updates? I've bought 3rd party batteries before, for my HTC Sensation. Something similar, 2x1900mAh + charger, but theose were Anker, and they were pretty good. Lasted longer than the stock one.
I'm considering trying these as I find it very comfortable to have spare batteries and a battery charger.

I can understand your skepticism. I am one hell of skeptical person too. But I do owe these Qcell batteries (I bought a pair with a charger) and have had them for 4/5 months now. No problems absolutely.
Take the 2050mah for granted. They are not any higher than stock. But the build quality is very good at least for me.

I've had great experience with my 2100 vzw extended battery but that's made by Samsung.
