Has anyone tried one of these cheapo ebay extended batteries?

Found this extended battery on ebay, was wondering if anyone on here has tried it, i know it looks hideous, but if you know your making a trip somewhere it could come in handy if it works the way its supposed to. Its cheap as hell too.

9 bucks... can't be too great,
but what can you lose? lol

Seems to me that if the larger aftermarket brands have trouble meeting the stated mAh rating on their batteries, what more of unbranded ones that goes for an even lower value?
I also still have very clear memory on exploding phones from third party batteries years ago

I bought a cheapo 3800mah and it lasts barely longer than my stock extended battery. I wish samsung made an official 3800mah version

Buy 2 stock batteries and solder them together. Works great.
3500 real mah. I didn't think the 2000 extended batteries would fit under the cover from the Hyperion I had here. I agree though, if I can solder it up in an evening, Samsung certainly could work up something.

hopefully more phones in the future will be like the razr and give us a factory extended battery closer to 3000mah.

Razr maxx when I had it for a week was sick! Hard use all day, charged every other day, seriously insane battery life. If that phone ever gets bootloader unlocked, I would be all over it again.

Have you done this solder thing? Any tips?

if you look at the battery in the phone you can see that there is some space at the top of each terminal, use this space to solder a fine piece of copper wire to a second battery. make sure to solder the batteries in parallel, positive to positive and negative to negative, to retain the same voltage.
i remember taking apart a so called 3500mah battery from ebay and they were just two cheap 1500mah batteries tapped together. Apparently in china 1500X2 is 3500.

Why does everyone want extended batteries? 99% of people have access to a power cord most of the day and just don't need it. Granted, I'm new to the phone, but I really hope I don't need to carry around a huge battery or two. Personally I'd rather charge it more often. Just my own opinion.

I bought a 3600 mAh extended battery for a few dollars on ebay. Despite the fact that it makes my phone look like a beached whale, it totally got rid of my power shortage anxiety. My most useful ebay purchase so far..

Even If it's 1500 that's still 3000mah for less than $10. Pretty good deal.

As long as you know that I don't see a problem. Spend $10, use it for 6 months, buy another one. Much better than spending $100 for a mugen.
Even the Samsung batteries lose their capacity over time.

Any standard size extended batteries with NFC yet?

I know there are the mega sized batteries that add extra bulk. Looking for extended batteries that are the same size as stock and with NFC.

Thanks! Pretty pricey for a 200mah increase but it's good to know we have options. I'll probably wait for a price drop though.

only 100mah more but they are decent batteries i had some for my gs2 but no NFC. Good if your going on a trip or something and need that extra battery, I didn't trust as long term though. I had gotten a 2 pack with a universal charger for like $20 for my gs2

Yea, I had an Anker battery for my EVO 3D and they're solid. Definitely want one with NFC though.

i am in the same boat but don't want to walk around with a brick with those 4000mah batteries. to me that defeats the purpose of this ultra thin phone. i keep an extra battery in car in case i need it.
i don't think you will find a decent capacity (say 2800-3000mah) battery without requiring a bulky extended back cover.. those that advertise this type of capacity are probably liars. i said it before, but if it were possible samsung would of increase capacity while keeping the same size.
sure you can get a 2200-2300mah battery that is the same size but it's pointless because the added time will only be like an additional 10-20 minutes compare to stock (that is of course if you even get the advertised capacity)..
battery technology needs improvement.. everyone is making better and better phones but battery technology is lacking and no on is investing money to improve them

Yep using this at the moment - NFC reception seems better on it - recognises a tag from a greater distance. Also, feels like it actually is providing 2300mAh

QCell has 2300mah batteries with nfc for $10 on Amazon.
Originally bought it as a backup, but it consistently lasts longer then the OEM battery so now that's become my backup.

I read that those QCell batteries are fake. Supposedly if you peel back the sticker, they're really 2100mah.

Damn it. I wish I didn't listen and question this. The QCell I got does not have a label beneath their sticker or indication that it is 2100mah, but when peeling it back I tore the connector to the nfc. :'(

[Q] Note 2 N7105 battery voltage and back cover

Does any one know is the back covers of N7100 and N7105 are same or not, i mean will it fit on each other?
Also, one major thing i noticed was that the Original battery that comes with both these phones states as 3.8v, but on ebay the higher capacity batteries (like 6500mAh) has 3.7v written on them. But they still say it's compatible with both these phones. And some buyers even left positive feed backs about how good the battery is. If the Voltages are not the same shouldn't it cause problems?
I was planning on buying one of those higher capacity batteries for the N7105 until i noticed that voltage difference.
Oh and one more thing, does the battery on both these phones work on each other?

Look on eBay you will see original back covers fit both.
Batteries are same.
Voltage changes as battery drains its not a set thing, look at your charger it will most likely say 5 volts .... when you charge a 3.7/8 v lithium cell it should be ideally charged to 4.2v it complicated if you aren't into electronics.
Basically don't take any notice of 3.7 or 3.8 .. it will be correct.

In ebay for every high capacity battary (5000mAh, 5200Mah, 6500mAh, 7000mAh, ...) they give a free modified back cover with it.
But after reading many reviews and googling, the best battery for your Note 2 is currently ZeroLemon (9300mAh). The protective cover which comes with this battery is pretty sweet. And your fone can last 3 days + without recharging.

Im sure there are others. I would guess anything made and assembled at same plant would be best, please correct me if im wrong.

You get what you pay for, I pay for a warranty I can trust as cheap batteries are too dangerous.
There's also a specific section for accessories.

Jut wondering if anyone has had any dealings with these batteries.
Also, I know there is a accessories sections, but this was a question, so I asked it in the Q&A section.

I have only ever used Anchor battery and found them faultless .
Their was a post in Accessories at one time .

Anchor or Anker? I also use Anker, just had a problem with my set of year old ones starting to swell -they replaced them both without quibble.

I looked on their site and only found a 2200mAh battery, the bigger ones are double sized with the retrofit back plate.
Stock battery is only 2100mAh, so the Anker one isn't that much better =/

If the battery fits inside the standard back plate then it is the same capacity (or even less) as the standard battery, it's physically impossible for it to be any greater. Any advert saying a higher capacity for the same size is lying, so avoid.
Main point about the Anker is having two batteries, so you charge outside the phone and always have a fully charged spare to hand.

I'm not going to question ur knowledge about this, but how can u have different mAh "AA" batteries, that are all the same size in that case??
I don't want to have to carry around a second battery with me all the time, this is why I was looking at different bigger capacity batteries =/

You can buy AA batteries in many different forms, alkaline, NiCad, Li-ion etc. Each has a different power density, with Li-ion being the highest. Standard S3 batteries are already the highest density so can't be bettered, if it were that easy then Samsung would have already done it.
The only way to get more capacity is to increase the physical dimensions, don't take my word for it try Wikipedia.

S4's battery isn't much bigger, but capacity is much higher.
Personally I carry two slim zerolemons charged at 40% with me all the time.

me and wife have zerolemon 2300 in our gs3's, fit under original back door and they come with 180day warranty. only downside is no NFC. But to me its the Best 20 buck investment ive made as far as accessories lol.

I've found the zerolemon 2300mAh batteries on eBay, HERE and I have also done some web searches about them, they look pretty good and I haven't found any bad reviews. 200mAh bigger than stock, and tested to be that capacity too, so must be true. I'm thinking of going for these, will just have to get a US to UK plug adaptor to go with the charger, lol.

? No, you weren't at all rude -I wouldn't suggest anyone accept 'internet advise' without cross checking it against something else.
The batteries you've chosen have a modest claim for capacity so are probably genuine. Only drawbacks are the limited warranty and return postage, if ever required. The desktop battery charger I have looks identical, plugs into a standard micro usb charger so you might not need an adaptor.

Replacement batteries, which one is good?

Hi everyone,
I've been thinking about replacing my battery and a quick search on Ebay led me to find some sellers who claim to have a 3700 mAh batteries.
Now my first response is to not trust these batteries and just get an original one, which I probably will, but I'm really curious if anyone here has tried one?
Here are a couple of links to these 3700 mAh batteries:
https://www.ebay.com/itm/BLP633-370...342121?hash=item1edc516aa9:g:~BMAAOSwoX5asMid

https://www.ebay.com/itm/3700mAh-BL...652403?hash=item2cd4142a73:g:wjEAAOSwsxJa9Isl
What are your thoughts about these?

Don't get any battery that isn't a OnePlus Battery. If you have a choice, never go for the battery that is advertised with a different amperage.
Go for a 3400mAh battery, better if it's a OnePlus original. Since our devices uses Dash Charge, which is only on OnePlus devices, it's best to go for an original, since we cannot know what effect DC will have on third party batteries.
Unless your battery has degraded lower than 50% and you need an emergency replacement till your original arrives, these batteries should not be trusted. There even may be a risk of high thermals and degrading your other phone hardware too.

Rated means how much it is designed to have, and tested is the actual amount of MAh in the battery. With every battery there is a difference between rated and tested. 3300MAh tested is actually really good.
I wonder how much the original batteries are tested for.

In their page, they say "Capacity: 3300mAh (rated) 3400mAh (typical)"

BTW, does anyone notice that after replacing the battery, the AccuBattery app is completely out of whack?
I cleared the data to get some clean info on my new battery, but after two or three charges, the app sees my new battery as ~2500mAh and with every charge it's rising. (My last battery was calculated as ~2800mAh)
So far it seems that the battery lasts longer, so the data from the app is conflicting...
I know that the AB app data isn't really reliable in comparison to real measuring equipment, but I'm just wondering about this.

I have replaced it, but it says that it have 0% charge, and doesn't charge anymore. Any help?
Edit: The seller have sent one more to me; it's corrupt, they say.

In my experience non-OEM batteries start to degrade after a few months. How has yours held up? I'm looking to replace mine if I can find a genuine OEM part.

The one I bought is supposed to be genuine, it even bears a OnePlus logo. But the first died on me in a week or two, so I got a free replacement from them, and so far it fares great. AccuBattery reports it as being well above 3000mAh, and I can reach the end of the day with my phone again, so I'm quite happy.

so why does everyone praise oneplus for their easy to repair devices and parts and build quality and all, if I can't even buy a replacement part? I'm forced to buy a new phone because my battery is broken. So next time I will go and buy a Samsung. Harder to open and all but I can buy a original battery in any other store.

There are plenty of stores that sell original batteries. And a plethora of non-original batteries to choose from too.

I just send my phone back to OP and have them replace the battery under warranty (It's covered.)
