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?

Mugen Power batteries in early 2011?

According to a rep I emailed, Mugen Power is making extended life batteries for our battery eating HTC Glacier that should be released sometime early 2011. For those who don't know Mugen Power, they have a reputation for making extended life batteries for every popular smart phone on the market.
Typically they'll make 2 different batteries for each phone, one that aims to fit like a stock with an added 400 or so mah, the second tends to require a custom backing and can often be double the stock mah.
Honestly? I can't wait. ^.^

In the tests I see Mugen did absolutely terrible. In my experience they *can* make good batteries, but have terrible Q.C. The 1st batt I received for my N900 only lasted about half an hour when fully charged. The second lasted over two days on a charge, when stock couldn't even last one.
They seem to be very much a "luck of the draw" kind of company.

posted this in the seido innocell thread as well:
dunno where i saw it (somewhere here on xda prolly N1 forum) but some guys put every aftermarket battery for MANY phones up against HTC's stock batteries the astounding results:
NO aftermarket battery from ANY mfg. has EVER beaten HTC's stock battery...
(this is referring to batteries that fit in stock battery enclosure)

I disagree fella, I myself can verify that Mugen power LiIon battery is superior comparing mAh to mAh against stock HTC batteries. I mean its not just BS they do have respected branch in the market when it comes to manufacturing batteries which is durable and long lasting which is tested by many. But for it to work you have to completely discharge it few times I normally do it for 2-3days before actual use for optical performance.

Okay so this morning after I replaced the Mugen battery with stock battery I fully charged it and took this screenshot.

Now keep in mind the stock battery is 1230 mAh and the Mugen power stock size battery was 1300 mAh. So the only difference here was 70+ extra mAh yet after extended test and usage I can respectfully say I got 3-4hours extra with Mugen than the stock size which is alot when you compare the batteries and its only 70 mAh extra which is nothing.
Now keep in mind from those SS the TBattery 0.60 does not verify the actual full mAh as its preset to the max of stock battery which is bug in the program. At the beginning to me it did seem the stock battery was superior as time went on and after many full discharges, Mugen power battery come on top.

Both battery's are listed but aren't shipping till Feb. 18th. They could be manufacturing them. 1650mah is the normal sized one. I think I will get that one.

I think I might also. Not sure about the extra bulk of the big one.

Wait for sometimes as 1650mAh is selling for $47 ATM which is a lot considering mAhs per dollar count, also they are out of stock. Trust me guy I am pro mugen fella as you can see my SS few post above, ill wait till it hits 30s.

Battery Feedback

New Thunderbolt user Still have my DINC.. I don't think I can let this thing go.
I need some clarification:
Can the EVO battery and door work on the thunderbolt?
Has anyone tried the 3500 MAH battery from the EVO on the Thunderbolt?
Are all the HTC battery's inter-changable? I have the 3500 mah battery on the incredible does anyone know if that would work?
Does anyone have a good link to the best battery out there high maH...
I know there is a 4500 mah that is just ugly anything lower that anyone has had experience with would be good information.

I don't think EVO batteries work if I remember correctly from another thread. Check out the HTC 2700mah battery, not as big and ugly as the 3500mah one. Hope this helps!

Nah brah, I use to have the incre before the thunderbolt. I also try to use the same one but the batterys are very dif.

get the default verizon extended battery, it adds some weight and girth, but the phone last all day even using it all day(in a retarded, i don't work at work fashion).

I believe the only HTC phone that has a compatible battery is the HTC my touch 4g. I purchased the OEM extended battery that VZW sells and love it.

The MT4G batteries do work I believe. As far as the batery goes just get the 2750 extended battery that Verizon carries. It lasts a while for me I love having it! Well worth the money!

+1 here, the VZW 2750 is a beast, and there are a few cases that fit it now also.

honestly i have had no problems with the stock battery. i get 14 hours (the time im actually awake) out of my phone every day with 30% left every day. i use it moderately, mostly wifi use and gps use. im running lts and lean kernel.

Evo batteries will not work on the device. I also recommend the Verizon store HTC extended battery it'll last the whole day. Get a seidio case if you want to add protection.

Go with the OEM HTC 2750, it's the best out there.

Ummm yeah no, even from looking at Evo 3d batteries on the internet you can clearly see they are not the correct shape and are square vs the rectangular shape on the Thunderbolt.

I have the 1750mAh slimline but found through some testing that it doesn't last appreciably longer than the stock battery. I also have the VZW extended battery for use on long trips.

I have the Verizon extended battery with the Verizon extended battery hard case with slide in clip and I love it, it really isn't that much bulk I barely notice it anymore. And my battery life was dramatically improved I went from half a day to 2days with a good amount of usage. Yesterday I charged it fully and worked from 11-8, used it for a few texts not much usage tho and had 94 percent left.

Anker 1750mah Replacement Battery

Hello,
I've had terrible battery life on my GSII for the longest time now. I've tried countless ROMs, Kernels, Modems, combinations and nothing has worked. At this point I'm fairly convinced it's a hardware issue. The cheapest/easiest route is to replace my battery. I know the Anker 1900 mah comes well recommended, but has anyone tried their 1750 mah model?
Here's the one I'm looking at specifically:
http://www.ebay.com/itm/Anker-Batte...726270?pt=PDA_Accessories&hash=item3371b0867e
I'm hoping it's the "1900 mah" battery that's gotten so many good reviews, but properly labelled this time around. Any thoughts? Anyone have this battery?
Thanks!

I have the anker 1900mah. It is a tight fit. I didnt have any problems with it but case/cover extended battery are a more practical way to go.
Just buy a case/cover battery from ebay ... it will add another 2200mAh to your existing battery.. .while it is bulkier, it is not that unuseable. It will keep your phone powered for at least 8 hours under intense usage.... (a lot more hours if you do not much)... When the case battery is drained down, you can easily remove it and have your old phone back.
But to extend the life of your battery on your phone, you are better off running it down to 40% before attaching the extended case battery. The case battery will automatically charge your phone battery back to 100%, while it gets drained down. And itself will run out first. This way you minimize the time spent with the bulk.

I'm going to go ahead and order the 1750 mah later today. Once they come in I'll let you know how they perform!

how is your experience with your new Anker 1900 mah?

I've been using the Anker 1900aMh for about a year, got two & a charger for £15 from Amazon. I highly recommend them, last longer than original & having a spare in the pocket makes it certain I NEVER RUN OUT of gas
l]

can you use the 1750 or the 1900 with the original cover?
i have the 2000 version from samsung. but you need a little bit bigger case (included) their.

The 1900 mah is supposed to be a tight fit with the standard battery cover. My 1750 mah batteries should be coming in today so we'll see how they fit.

I experienced Anker batteries to have drop down in power during time.
For 2 months it was fine.. but after i starting loosing power.. according to Battery Monitor Anker after 4 months of use lost 34% of its max power...

If you drain your battery down too much or leave it empty uncharged, that can happen

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.
