Well I was looking for spare batteries and came across these. I ordered a pair and will get them sometime this week. I decided to share the link if anyone is looking for spare battery with a charging station for the battery. For me this should be fine since I can usually get through the day with a full charge and on certain occasions a small charge when I play some games and having a spare would be great. At this good price

Edit: the batteries don't seem to be OEM and overheat my phone. Im not sure of any long term effect this may on our phones, but I personally won't take this risk.

it's probably a china battery. I have the same brand charger for my G2 and I keep my oem battery in it just incase. That battery probably won't have nfc, but it should serve well as a back up.

You need to check if the battery is fake. I got 2 with the charger from ebay for 18.99. First sign that it was fake was the NFC didn't work even though the sticker says Near Field Communication on it. You can also check the voltage with AndroSensor from the play store. The real battery puts out 3.716 volts where as the fake one puts out 3.8 somethng. Im not sure if it is even safe to use . I was looking for info on it when I found this post.I found that in china they sell the blank batteries that are identical shape and size to the real batteries and will even put the stickers on for you... Im pretty sure yours is fake too from the price. Samsung sells these batteries for $30+
Edit- if it does turn out to be fake you should change the name of the post to fake OEM batteries. My seller was Feng4258 located in china and he had a pretty good rating like 98%. The 2% were accusing him of selling fake or defective batteries. I wish I would have checked that before I bought. I'm requesting a refund now and if he doesn't comply I'm going to be opening a case with PayPal and ebay.

Thanks for the input, well if NFC doesn't work then that's not a huge loss for me as it is still pretty useful for me at least. I'll be sure to check the voltage and how good it performs.

Update: yeah turns out that you were right. The batteries do hold a voltage well over 3.7. I just contacted the seller about this issue and hope to get a refund or will have to contact eBay. Thanks again for your input.

Is there a condition that the battery has to be in in order to measure the voltage? My understanding is that the battery voltage is not a constant property of the battery but changes depending on it's state of charge (ie fully charged, half charged, completely drained, etc). If that is the case I don't think you can "spot" a fake battery by voltage.
Is it useful?

With my stock battery, andro sensor says im running at 3.86 volts?
Sent from my Galaxy Nexus using xda app-developers app
Yes you are correct at the time my original battery what showing 3.7 and the fake was showing 3.8 but from what I've read its just a matter of charge level. The batteries work fine and in my experience are safe to use. With that said they are not OEM and really the only way to tell is to check the NFC. Also if they come in anything other than a Samsung case then they are probably fake. I told my seller I was going to open a close with eBay and PayPal to gt my money back and he sent a message back the next day saying "Very sorry, seller very misleading. Money back in account, check please!" I tried calling Samsung before just to make sure but they can't tell a fake from the s/n. If the NFC feature isn't present its a fake. Contact your seller immediately and demand a refund. Enjoy your free fake batteries. The charge holds alright but it does suck their isn't any NFC especially since Google wallet has started to support all major credit cards.

Is this with the battery fully charged or half way? All lithium batteries fully charge around 4.2v, for phones I assume they will fully charge around 4.1v or so.
3.7v is just the voltage that is recommended for long term storing of the battery to prevent wear.
Yeah I personally would not recommend these batteries. They have started to overheat my phone and the voltage never gets below 3.86. I don't really use NFC so I can't really say if that works or not.

Yea i been noticing that the higher the battery level the higher the voltage, and it goes down as the battery level goes down. So im not so sure about the voltage being an indicator. NFC is the only way to tell. I just bought a battery from a seller in south korea and its real, nfc works and all. The label and writing looks abit different though, im assuming its because its a korean made battery not made in korea and finished in china

Will these batteries work with the regular battery cover of the Atrix 4G or does it require a new cover like the mugen ones. If it needs a new cover thumbs down! If not I might buy 1
Let me know !
Also do you have any issues with the 2300mah battery's stats not reading correctly....I read that 2000mah is the maximum in which the phones hardware can read. If your 2300mah is reading correctly that's interesting.
I used these - very bad.
My atrix was not able to get actual charge state. Could see 100% and then suddenly fall to 0% and phone switches off. Or can see 5% for hours after full night charge.
Bad stuff

I always use the supplied wall charger that comes with these so Idk, lots of the extended battery reviews on here are the same voltage & they seem to be doing pretty good.
It's not the charger which matters but the phone itself which charges the battery, it's aiming for 4.3V as that's what it thinks it should have as the stock battery is designed for that. Although I haven't heard a single case of these 4.2V batteries having problems with being charged with 4.3V, that last part can be changed in the kernel and the charger chip driver. I'm getting some knock-off cheap battery myself so I'll see how it goes. This particular one seems quite steep in price @ $30, with proven ones like the PolarCell 2400mAh going out for half the cost.
you won't see the affect right away from overcharging. I use to play with a lot of batteries from RC, overcharging something we use to do get slight edge and boost at start. but it does have long term damage to batteries, specially lithium based. some cheaper batteries even catch fire.
Alright guys, got the batteries in the mail today, charging one & will report back later

Li-ion batteries have an overcharge protection circuit built into the battery pack itself and should prevent this from happening. If everything is working as intended, it should be impossible for the phone to overcharge a battery. That's not to say the protection circuit couldn't fail itself.
And I too played with RC batteries and you really can't compare those batteries with these. Different types of battery with different methods of charging.

I have the 4500mAh battery and am VERY happy with it. I am not impressed by advertising that says "Highest capacity slim profile battery". That may be so, but you can only get so much power from a slim line battery. I thought I would never go to a battery that would require changing the size of my phone by putting on a different battery cover, BUT I'm glad I did.
The 4500mHh battery has been well worth it, IMHO. Got it from Gorilla gadgets, BTW.
Looks like it doesn't support NFC. I know that's a deal breaker for some.
I wouldn't trust anyone but Samsung to build a battery that fits under our stock battery cover that provides anything more than we already get.

Sent from my Galaxy S3 using neighbors wifi
Yes the instructions say charge for 12 hours before use and they have a break in of 5-6 charges for full battery life. Also they have NFC enabled crossed of in black sharpie on them the charger feels a little cheap too and flickers when you have your phone on the USB port while charging one oft the batteries. How they expect us to charge them both for 12 hours is odd the one I put in my phone charged much quicker than that and leaving it on longer is pointless as when they hit full safe chargers stop charging the batteries.
Battery 1 finished in 10 hours on the charger battery 2 finished in 2 hours in phone on stock charger stock battery is in charger now.
Charger had the following colors for led
Blue- no battery powered
Pink-battery charging
Purple- battery done
Also while charging and using the USB port is possible the charger led flickers when doing so. I don't believe it has enough amps to power both unfortunately. None of the batteries got warm at all while charging.
As for NFC Samsung should have never put it in the battery to begin with I'm thinking about getting a galaxy note 2 back pulling the NFC ant out of it and putting it in my s3 as they put the contacts for wireless charging and NFC external ant in our phones.

you can see the size difference in the battery size is major but the battery for the nexus does last pretty damn good for some reason. on the nexus battery on the side where the metal connections are i shaved off the tabs on that side look at pics lol

It might run okay for now, but in the end you'll blow up the battery and make the phone unstable. The GN3 battery is 3.8V while the GNex battery is 3.7V. Yes, that 0.1V makes a difference - the phone will charge the GNex battery with a too high voltage which can cause it to overheat and swell. The phone running off 3.7V will be underpowered and might or might not randomly crash.

It's not that big of a deal. Lithium batteries have an upper limit of 4.2 Volts which is why if you use a general purpose charger such as those used for charging RC packs you can charge Li-Ion and Li-Po batteries both on the same setting. Either way it charges them up to 4.2V and then cuts off. Once a load is applied, the battery drops to its nominal voltage - 3.7 or 3.8V and remains at that level for most of its life before rapidly dropping off when it gets low. When this happens cut-off circuitry kicks in around 3.2V or so to prevent the battery from discharging too much which will permanently damage it. Since the battery can't be safely charged above 4.2 or let drop below 3.2 or so, all the charging and discharging is managed by a chip designed for that purpose. Also, it means that you can't overcharge your battery by leaving your phone plugged in 24/7 as the charging chip will stop charging when it reaches that upper limit.

Lithium ion batteries with a nominal 3.7 voltage should be charged to 4.20 V or so.
Lithium ion batteries with a nominal 3.8 voltage are typically charged to 4.30 or 4.35 V. It's a new type of lithium ion battery with different chemistry, and hence the different voltages. If you take a battery meant to be charged to 4.20 V and repeatedly charge it to 4.35 V, its cycle life will be significantly reduced. 0.1 V difference will reduce the cycle life by something on the order of 50%. Here is a reference: http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Apple, Samsung, and Motorola seem to be using this new type of battery, and the phones are charging them to 4.30 or 4.35 V. I'm not sure how widespread the technology is or if it has trickled into aftermarket battery offerings.
I commend you for your work and glad your getting more battery life with this mod but I'm sure most of us are fine with the life of the phone stock gives us without any modifications or just wait til zero lemon releases their behemoth 10k mah battery with zero shock case to protect the phone.

Here is a reference: http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Apple, Samsung, and Motorola seem to be using this new type of battery, and the phones are charging them to 4.30 or 4.35 V. I'm not sure how widespread the technology is or if it has trickled into aftermarket battery offerings.

But with this new 'smart battery' and 'smart charger' system it seems very likely that the battery's capabilities are read by the charger so that the charger will not cause damage. It might be that the charger will adjust the charging protocol if it can support the battery's needs, or perhaps refuse to charge an unsupported battery. I think if he measures the charging voltage he might find that it is different for the two batteries.

Thanks to this, I will have more battery life. Cheers! Just kidding!
Thanks
