Chinese 3500 mah batteries actually 2 batteries stuck together!

I bought two of these Chinese 3500 mah batteries for like $20 from eBay. They were charging like 1500 mah batteries and not lasting as long as they should. I figured, what the hell and tore one apart. Here is what I saw:
Not one solid battery but two stuck together with a metal strip connecting the two. Is this normal for this type of battery or is it supposed to be one solid piece? This looked very jerry-rigged to me.
The serial number on it is 044060A. Do your own research on that but I came up with just the fact it is a Chinese battery as one would expect. When I went to the site that sells them it did not indicate the mah of the battery. Very odd because how would you know what you are buying? It did confirm the 3.7 voltage however.
Here are pics. Please forgive my dirty fingernails as was putting down hardwood mulch in the garden all day

There could be a wire connection somewhere in those two, but yea man... Sad to say it looks like you may have gotten a rip off.
Sorry man.
Any way you can take it somewhere to get it tested fully?

Wow thats ghetto!
Would you mind posting the link for the auction? Perhaps as awareness to the rest of the forum to not buy from.

Lol, can't recall what auction I bought these at.
However, I am pretty sure that all of these $5 3500 mah batteries are pretty much this.
My guess is they get all the seconds (defective) batteries from this manufacturer, solder them together, put a pretty package on em and sell em on eBay.

most large batteries are made this way, take apart your cordless drill battery and it will be smaller batteries linked together, hell take apart a 9 volt and see what is inside so it is not unusual to put batteries together like this

Ok, cool, didnt know. Was just wondering why it was performing like a 1200 mah battery and not a 3500.

Wow. I have bought two 3500mAh batteries on ebay... so far so good. I can go for almost 2 days without charging with normal use. The stock battery had to be charge about 3 times a day.
The sellers (ebay) were: wanshopping and feitong2009. My only compliant was with feitong2009 which took a month to get the battery which was coming from Hong Kong. I normally get Hong Kong products in about 2 weeks.

How long does it take to fully charge your battery from empty? Divide minutes by 60 then multiply by 650 and you'll be close to your true mah.

Nothing too surprising about it being two cells connected in parallel internally. If the internal cells are supposed to be 1500mah like stock then the battery should have a 3000mAh total capacity. Even if they kind of suck at 1200mah each, 2400mah is still a pretty big improvement over 1500mah.
Oh, and if you weren't getting the performance you were expecting from the battery, did you try wiping your battery stats? The percentage meter on the phone is going to act a bit wonky if it is calibrated for a much smaller battery. I've got one of these batteries and after wiping the stats it shows a definite improvement over the stock battery.

Did you wipe the battery starts when empty or full or does it matter?

"sprint" oem 3500 bat w/door?

i just bought the following for like $25 bucks.. any thoughts?

Well ill find out with you, I bought one to. :-o

I mean, its a measly $25... couldn't find any proof this is a genuine sprint oem or not... also picked up a HTC incredible 1800Mah for $6.

Nice find. Got my Platinum 3500mAh for $21 shipped
Found it at amazon for $49. There is one review.
http://www.amazon.com/EXTENDED-HTC-Supersonic-T-Mobile-35H00124-12M/dp/B004OTNHTO

I don't want to be a pooper, but the battery in that Image looks like the stock evo battery which is 1500mah.
I also don't think sprint sells an OEM 3500 mah battery, they do have an extended 2200mah, and even that is larger and comes with a door. Also I've NEVER seen a 3500mah that small.

The Sprint OEM batteries are black with a white label, not red. So it definitely is not a sprint/htc oem battery. They also don't have any 3500 mah batteries for any phone that I could find.
Checked HTC, and they also only sell the 1500mah battery. They don't have any others at all.
Not going to say your not getting an actual 3500 mah battery, but I will say for certain that your not getting an OEM sprint or HTC battery.

Yeah i dont think this is real either, Sprint already has a extended battery and htc does not sell any extended batteries , if they did it would show up in HTC's online store.

I did a google search for the model number in the Amazon listing (BTE6300, BTE6300B, 35H00124-12M). That battery is only rated for 2150 mAh.

When I get this battery, is there a way I can charge and take a multimeter or something to test it?
Sent from my EVO (iPhone Slayer) via XDA App

The stock battery that came with my original Evo was red. HTC makes red batteries. Not to say that this battery is legit, though...

It's not OEM, there is no OEM 3500 mah battery. Here it is from a different seller, same battery. Most of these "3500" mah batteris are the same battery just with different wrappings.
http://cgi.ebay.com/NEW-Acesoft-350...ccessories&hash=item336560a609#ht_2595wt_1141

This should probably be reported, since they are trying to sell it as Sprint OEM, and it doesn't seem likely that it is. Or at least tell the seller to remove those words from the listing.

It's fake, htc doesn't make a 3500.

you would have to charge it full and for lack of better eletronics experience. You would need to use a resistor that would pull the mAh of the battery.
take for instance the 3500 mAh battery that battery can give out 3500 mA over an hour

Not to mention that the Sprint extended battery is not red....... Its black with a silver sticker.

i got mine today, its a daily pc battery and cover. Everything fits great. Ill get it charged up and let you know how it preforms. I like the cover better than some others Ive seen much cleaner look and a good feel. I think its a good price $25 shipped.

i got mine last week as well,. currently off charger, heavy to mod use, (fb, ebuddy, some birds, BT and wifi).. 4hr50m off charger @ 69% left..
def worth the 25.

Only official Sprint extended battery is the 2600mAh.
I also have a Seidio Innocell 3500mAh which is awesome. If you want official go with the Sprint 2600mAh otherwise, I'd go with the Seidio 3500mAh any day of the week.

70$ for the Seidio 3500mAh battery wow, I think I'll hold off a bit longer. LOLz

Using tethering for my ipad 2 wifi and downloading bt using ttorrent regularly. stock battery can't last me a day. This one can last me full day with around 15% left.
Also got a galaxy nexus battery rated at 2050mAh

Can you comment on the 2050 MAh battery? Does it fit with the stock back cover? Doesn't really seem legit as the OEM extended requires a different back cover.
Might be worth the risk checking it out for $15...

You can use original cover with the 2050mAh battery from what i tried here

How about NFC?

NFC is unavailable for all third party batteries as far as I'm aware

Unless the third-party in question chooses to equip their batteries with a suitable aerial.
As this is the first thread I'm aware of featuring this particular brand of battery, it's worth asking.

can u tell us if the 2050mah worths the stock battery or if its better?

Nice Find! Ordered, seems like our phone might finally function as a replacement for a handheld GPS (Garmin, Magellan etc...)

I would love to hear your thoughts on the 2050mAh battery. It seems like a lot of these aftermarket batteries don't do any better than the stock battery even with the higher charge capacity.

I am getting the 2050mAH batteries on Monday and will test it out.

Any updates?

bump for updates pls

it's running quite well. I'm getting around 20% power left on a full day of internet / chatting / a family guy and simpsons video / 30 mins tethering. This thing is a beast compare to the original battery!

such things are REALLY ugly. But I understand why we need it.
So the question is, why there can't be something as slim as Razr MAXX's 3300mah battery? ...
In the past I thought it is technological impossible to produce the slim extended battery like Maxx's, until I see how Razr Maxx works.
It is thicker than Original Razr, but it is so much better in design with giant battery.

Think it has something to do with the fact that it isn't removable, but I may be wrong.
Do they make these for the LTE variant? Seidio has a 3850 battery but it costs almost $70 and this is only $20!

The 2050mah i am getting around 1 and half hour more than usual compare to stock.

4150mAh? That is more than my laptop's battery. I would love to see what kind of runtimes you get with that beast

Wow! Thanks for the heads up on this. Ordering one of each.

Would love to hear the results on the slim battery - wonder if it really reads higher than the stock 2500mah battery.

These seem awfully cheap. Is QCell a reputable manufacturer of batteries?

omg it looks so ugly and for sure it will burn your galaxy note... have fun ^^

Waiting eagerly for reviews of both ...
Somewhat dubious at that price though

Can you please post some picture with the extended battery and cover attached to the Note

Here's pretty accurate picture

Voltage * capacity = total power
Your laptop battery is around ~15V, which is 4 to 5 times higher than the battery in the note.

the lack of the polarity signs on top, and the price , and the fact that they are chinese batterys http.. etc etc ..superexporter.com/suppliers/quality111699398794775225-ningbo_qcel_battery_co_ltdDOThtml (can´t post links) makes me believe that they are just like all the others chinese fakes in ebay, worth the buy .. but don´t be expecting big mah numbers.. in fact don´t even expect 80 % of the mah of stock battery

Agreed. I get about 50% of 'stated' mAh on my Chinese batteries. Still a good buy, don't get me wrong, but I am going to pay the extra $15 to get a stock battery now.

Did the 2800 give you more time or its fake?

isn't those chinese batteries harmful for the device .... and can any one post an image for the battery usage

4150mAh @ 3.7 volts though. I bet your laptop battery runs closer to 15 volts! THe more important figure is how many watt/hr's the battery can supply.
4150mAh @ 3.7v = 15.2625 watt/hr (4.125*3.7)
4150mAh @ 15v = 61.875 watt/hr (4.125*15)

anyone with the test reports of the same

not worth it.
I bought one of each and the slim one did not even last a day. And the thick one lasted exactly a day. I was surfing the net for about one hour constantly texting maybe a 2hr phn call total. And some games like temple run and asphalt. I still recommend the mugen 3400mah this lasted me a day and a half doing the same things.

Testing the ANKER 2200maH Battery

Recently I was contacted by LapTopMate.com and asked if I wanted to test one of the new ANKER extended batteries for the GS3. As someone who has used them for quite a while in other phones I said yes.
It arrived today and now I am charging it. Will do comparison on ON SCREEN time with the Standard battery.
Thanks ANKER!!

I just saw this battery on Ebay. The price is about 25 US Dollar. I am very interested in your results!

yea. doe the 100 mha more make that much of a diff?
NFC? does that work?

I don't see any reference to NFC on the packaging. But for a spare battery, it really doesn't matter. (I've never used NFC anyway.)
I'm hoping I get about 30 more minutes of screen time out of it. Time shall tell.

Anker batteries for the Galaxy s3 doesnt have NFC, yet!
i get about 2 hours of extra battery life with this battery.

So far so good at 50%.

Nice.any good links to vendors for this battery,I would like nav but I'm not using it yet anyway.

I've been using this battery for about a week now and it's a GREAT battery (minus not having nfc). For $8.99 on Amazon its an absolute steal and it holds a charge great.
For $9 you can't pass it up.

Yes it does.
No NFC though.
I got a little over 7 hours of on screen time at 1%. Failed to get a screen capture though.
Will run it through a second cycle to see how that one goes.

Bought 2 for 16$ on Ebay. Probably only need 1, but I may just sell the extra off on craigs or something.
They'll jack up the price once word gets spread out anyway.

I too was contacted by laptop mate and received a trial Anker 2300mAh battery for my Galaxy S III.
I already own two Hyperion batteries, and compared to those, my Anker battery is fantastic! While I would estimate that the Hyperion battery gets around 60-70% of what my stock battery gets, my Anker battery gets battery life on par (if not slightly better) than my stock battery.
However, I have a couple of gripes with it... One of the plastic "tabs" that separate each of the 4 battery terminals broke off on one end. This makes it so that I have to be sure to make the plastic tab straight so that I can charge the battery while it's in my phone. Otherwise, it switches very rapidly between "charging" and "battery disconnected" (though it remains powered on). I'm not too sure how that happened, but that may have been when I was putting it on/taking it off of my Hyperion battery charger. Another gripe is that it doesn't have NFC. Then again I haven't even found an opportunity for me to use NFC besides the Paypass CC terminals (and Google wallet doesn't work on Verizon, so that's bunk anyway.)
I would definitely recommend the Anker battery, especially if they add NFC in the future. It gets great battery life on par with the stock Samsung Battery at a much lower cost, and if you can take one or two minor manufacturing defects (that are easily fixed) on the battery terminals, then there's no reason not to pick one up in my mind.
