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

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.

So Ebay batteries?

So I know there are a couple of posts on here but I have found them a little hard to follow. I just got my captivate last sunday and on the stock 2.1 rogers rom I noticed that the battery life was very poor. Since then I am now running cog 3.01 i think and my battery life is now alot longer than before.
For the way I would like to use my phone It is still not enough for what would make me happy. my phone is unplugged at 6:00 am and when i get home by 5 it used to be dead but after "breaking in the battery" and the new rom i get home with about %15 percent battery.
I just bought a triple battery pack off of ebay for $10. these batteries are rated at 1500 mAh, the same as the battery that came with my phone. I am just wondering what I can expect from these batteries.
My plan is to drain two of them completely then leave them in my desk drawer(from what I have read if you plan on storing batteries they should be completely drained first) and use one of them plus my oem battery daily(until they start to lose performance). Again does anyone have any experience with a battery of the sort or any similar third party battery?

they are no where as good as samsung oem battery. even though it says 1500mah it is not or will drop drastically after a month or so of use...i've bought a lot of those batteries from ebay and they always like that even some other well known companies like Seidio do not compare with manufacture's batteries. the difference is usable capacity, oem batteries are around 95% compared to cheap chinese ones that are anywhere from 60-80%.

haha thanks that makes sense why they are so cheap, well i will probs by three new ones every months or so.

I have those ebay batteries. I bought the kit that comes with two batteries and an external charger for about $10.
The ebay battery is has about 60-70% of the power of the OEM battery. I have no real hard evidence just from using it for the past 2 months or so.
I am ok that it is does not last as long as OEM because it was only $10 and it came with the external charger. I love the external charger because it allows me to charge a spare battery while I keep one in my phone.

I bought the same ensemble, with essentially the same results excepting perhaps that one of my replacement batteries seems to underperform with about 40% of OEM battery life.
That said, for $10... they're very handy as backups. They'll easily give you a few more hours in a pinch, which is essentially just what I was looking for. I really have no complaints in that respect.
The best strategy for battery life I've found is to buy a handful of wall adapters and position them in places you spend a lot of time at, and to develop a habit of plugging in when you're not moving around.
Sad but true, but mediocre battery life is just kind of a way of life for these (and really all) high-performance Android devices. Excepting getting an outsized and expensive battery replacement like the Seidio 3500 mAh that all but prevents use with many accessories and cases, a couple wall chargers and a car charger are effective if mildly annoying means of managing it.
These generic Hong Kong replacements are entirely effective as emergency supplements, but you'll find yourself preferring the OEM cell still.

Yep I mean for $20 I have two charges and 4 batteries so if I need to go without power , even if not a 100% match for the oem power, it is still damn cheap.

I also got one of these from ebay.
I got the 2x 1500mah batteries + Battery Charger combo.
I must say I am impressed. They are the same quality as my OEM battery. Its so convenient. I never have to run to a charger anymore. Just keep the spare battery in my car or wherever and just pop it in and carry on with my daily business.
When I get home, I just re-charge all the batteries. The Battery Charger even has an LED Light that tells you when its finished. "RED: while charging" and "BLUE: when finished". Charging takes about roughly 3 hours, (just like OEM).
Edit: Been using this for about a month so far. With no problems.. Its the best feeling. My phone is never plugged in anymore. And, I don't have to "pinch the settings" to make my phone last.
IE. lowering brightness to 10%, turning sync off, turning wireless networks off, etc.
HIGHLY RECOMMEND!
only crappy thing is??? I plan to sell this phone soon, when the Galaxy S 2 comes out, if the specs are good enough.

Would you mind posting the link or giving us the name of the exact vendor you ordered from?... I'm about to order the 2xbatteries and charger combo, but just want to make sure I get batteries that are half way decent. When I search on eBay I get about 20 vendors selling similar combos and given that in HK they're celebrating Chinese New Year... most won't fulfill orders until next week.

i wouldnt waste your money unless you just want an extra.

Is there any 'special' features that the ET battery have over the Infuse? If not then I'm grabbing those 2200mAh batteries that doesn't require a new battery cover.

link ti that 2200mah battery?

http://www.amazon.com/Extended-Desi...S2KA/ref=sr_1_1?ie=UTF8&qid=1316165653&sr=8-1
Ebay has it cheaper but shipped from HK at $13

If you guys get that 2200 battery, let us know how it is.

I wouldn't get a generic battery. I try to stick with OEM stuff.

I agree with Korey, just because it says it's 2200mah certainly does not mean it is. It's probably just a re-labeled 1800mah.

To me, as long as it last as least the OEM I'll be fine (there's also those 1800mah for like $12 shipped). I don't plan to use these non-OEM for every day use but rather as backup on trips or emergencies.

well i had the same brand backup battery on my evo as a backup and when i first got it, it worked about as well as a standard battery and not quite more than that. then i stopped using the battery for a few months and when i went back to using it, it drained really really fast. i think there the long layoff from not using it may have contributed to it.
www.batteryboss.org has the stats on phone batteries and their actual maH
edit: also while reseaching different Epic batteries on amazon, there are actually different model batteries made for the epic, vibrant, and fascinate. one ends in "YV" and the other "VA". i think its due to different chips in the batteries that affect how they're charged.

I purchased the cheap replacement batteries for my hero a awhile back and the mah are larger but if you read the fine print on both of the batteries the watt hours are different. The new cheap batteries have lower watt hours and there for I found the original and the cheap batteries almost evened out.

Anker 1800mah on Amazon

http://www.amazon.com/Anker-Batteri..._26?s=wireless&ie=UTF8&qid=1316372694&sr=1-26
Read an article in the HTC Sensation forums where many of the posters picked up an Anker battery as a "Why the hell not for $15?" deal and had generally positive results. Did a search and not only does Amazon sell multiple varieties of Anker batteries, but many of them have a ton of positive reviews.
Before all the battery naysayers jump in and shout "You can't get an extra 300mah in a stock battery! It's another chinese scam and it's probably only 1.03mah!" the Sensation people explained it as being noticeably thicker than the stock battery while still fitting snugly inside the battery door. A good 1mm thicker at least.
Anyway, bought myself a pair along with a car charger for $30 for two batteries, a car charger, and a USB charger. Will let you all know if its a huge letdown, or if the positive reviews aren't just Chinese robots blowing smoke up our you-know-what.

Hey can you do a favor? Install battery calibration app from market and tell us how many mV (Milli volts) it say when the phone is truly 100% charged.

interested in seeing how those batteries are
was about to buy one
keep us posted

I've read in some of the comments on Amazon that they work best when the wall charger is used, though that may be because the wall charger keeps it at 100% while charging inside the phone causes the battery to drain down to 90% if left on the charger after it reaches 100%. Of course, the battery monitor won't tell you that to keep Samsung's support lines from clogging.
Thankfully this is Amazon and not the overseas shipping I had to deal with with my last battery, so it should arrive (according to Amazon) somewhere between the 23rd and 28th. Will test it heavily with my current ROM and let you all know how it fairs.

mV will not tell you anything about the capacity of a battery, only how close to fully charged it is.

True. If it's anything like the stock or mugen battery that I have, it'll cap out around 4250 for Froyo, 4200 for MIUI/Gingerbread.

Momax 1700mah is fine and chip.

Well, while discharging the first battery through normal use, I was actually getting a little frustrated that it was taking so long. Got about 24hrs out of it from wall charge to phone shut off, including about 8 - 9hrs of overnight standby.
Got the second battery off the charger and into the phone, and after about an hour it's still showing at 100% and 4100 - 4180ish millivolts.
Anyone, nothing is decided just yet. Will have to see how they hold up after the first 5 full charge and discharges that "sets" the batteries internal memory. Or whatever.
I thought these AOSP ROMS were supposed to drain battery, dammit!

Just about done "Breaking In" the new batteries. Two things: On the surface, they seem to last quite a while given the last time I tested the Mugen battery I was on Froyo and I'm now on MIUI.
From what I've heard, Gingerbread on the Vibrant, whether it's an i9000 leak like Malice or built from the ground up like Cyanogen 7 or MIUI, tends to burn battery faster than on Froyo. I'm also using different voltage settings, a different kernel... you all get the idea.
Apart from flashing back to Froyo, or completely redoing tests on my stock and Mugen batteries on top of the new Anker battery, whatever results I get will be a bit skewed.
Also, MIUI seems to allow the battery to get further down in power before shutting it off. Froyo would often cut me off around 3700, but I usually see MIUI showing battery power as low as 3300 before shutting down.

Your link points to the 2x package...if you look up the batt itself and read the reviews, most will tell you it's basically a cheaper oem replacement
http://www.amazon.com/Anker-1800mAh..._1_5?s=wireless&ie=UTF8&qid=1317360583&sr=1-5
Still a great deal at 11 bucks shipped.... by itself...and assuming it lasts...my original batt that came with my phone died couple of weeks ago... (less than 2hrs on a froyo rom...) had another oem that I'm using now..so far so good, but who knows...this seems like a great buy, but doesn't sounds like it's any kind of gain even with the 1800mAh rating...

Samsung Galaxy SII Touch batteries work in our phones. Tested.
They are 1800mah and can be found for $23 shipped. They are GENUINE Samsung as well so...it WILL be the advertised 1800mah. Just saying.

Even cheaper on ebay : http://www.ebay.com/itm/330601629006?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649
Sofiz has the Pisen battery for SGS II 1659 mAh, will this work on the Vibrant?

just ordered one too, hopefully it works out

Some reviewers saying battery only charges with wall charger and phone shows unsupported battery message. Those who have the battery please confirm.

I think I went over that at least 3 times already. Battery is a perfect fit. Charging is perfect (USB computer and Wall plug in). EVERYTHING WORKS with it. I wish people would read the topic more. It's only 2 pages. . .

Only reason it wouldn't charge in your phone is if you owned a Fascinate, in which case, get out of our forums, punk!

Ordered one from ebay and pretty happy with it so far. Only had it a couple days so far though and still messing around with different roms and kernels so hard to say exactly how long of a charge i get with it.

Got mine today, charging now. Thanks!

Just recieved mine from amazon, and so far its been great !

I bought the two off of ebay that come with the wall charger. I'm getting much improved battery life right now. I'm very happy with them. Even though they do make the phone slightly heavier, it's worth it IMHO.

[Q] External Charger

Does anyone know where I can get an external charger for my extended batteries that I will receive next week? I looked on amazon, but I couldn't find any that seemed right.

Ask MiguelHogue. He had one.

I have a cheap external charger for regular batteries, works great and should be fine with the extended too.

um. Maybe you want to tell the op where you got it since that was the point of his question.

Sorry I got mine on ebay its black and is unbranded. It has a light that is bright pink while charging and blue when done. It also has a usb port for charging with cable. Its all over ebay and amazon. Hope that helps.

I don't see why the cheap eBay ones (~$5) wouldn't work with an extended battery. (The cutout/space for the battery is the same size/shape as the one in the back of the phone)
But, it's only a couple of bucks more to get a charger with 1 or 2 (regular-size) batteries... might as well get a couple of spares?

I've been using mine for 6+ months, with no ill effects. (On both my Epic 4G and Epic 4G Touch - it's awesome that my backup phone uses the same size battery!)
Bought my cheap eBay charger for ~$10 with a "2200mAh" battery - I haven't noticed any longer life than my 1800mAh original. (It's probably that same "Chinese math" that gives us 4000W car audio amplifiers for $39.)
I have noticed that both batteries don't seem to be fully charged by this external charger - they show 100% when installed in my phone, but neither lasts quite as long compared to if they were charged in the phone. But, this is a small price to pay for having a (mostly) charged battery, ready to go at all times.
UPDATE: I bought some of the "Anker" brand batteries suggested in this thread, and they last a lot longer than the $4 ebay ones I was using previously. $20 for 2 good batteries + universal charger (Amazon) was worth it.

you can buy two ankers with a charger on amazon for $20. Those are actually quality batteries. Small price to pay for actual proven batteries rather than the crap your getting on ebay.

I've purchased several non-OEM batteries (and chargers) from cheap Chinese sellers, and had zero problems. The only battery I've ever had fail was the original Samsung battery in my Epic 4G. (It's slightly "puffed", and doesn't hold much of a charge anymore.)

UPDATE: My battery life was getting a little short, so I bought the Anker's suggested in this thread. The life is noticeably longer than my cheap eBay batteries. Not sure if they wore out sooner, or if they were poor to begin with. Either way, the ones you suggested last a lot longer. Thanks for the tip!
