Is it me or does the OP say in his title that it's about a 3500mah battery and then discuss the 2500mah battery. What's the 3500mah battery tag line about?

It's definitely a 3500mah battery. Just an typo I'd assume.

The back is thicker than the phone.. no thanks I will just continue to carry a spare battery.

These kind of batteries suck. If you need a decent backup just get an external battery. You can get an 8900mAh external that will last you more then you need. I always use mine when going on hiking or longer trips.. Generally where you would have a backpack of some smaller stuff. You do not need something like this for a days worth of common use.

I had one of those for my hero, get a big boost in life,. I went a three days without charge

What the hell is the point? I am getting nearly 20 hours of life out of my stock battery with two days of business use, and wifi. That looks awful as well.

You must not really use your phone like I do. Started at 8 today and its now 11 and im down to half battery even with overclock widget clocking it to 200Mhz when the screen is off
I bought one of these when the g1 came out and it gave me about 2 days off the charger. But im not sure how well this is gonna work with this phone. I really want to know how it worked with people who bought the smaller battery

If you dropped down that much you need to check your syncs and what using data. Is your phone set to cdma? I'm at 87% with 5 hours off the charger. Might as well solve whatever is eating up your battery first.

I take my phone off the charger around 6 every mourning and I don't lose the first bar till 1030 or so.that's with lots of text, internet, and some phone calls. Not a complaint here

I remember everyone was talking all this hype about the extended Seidio battery for the Mogul... I bought one... and was completely unsatisfied, I sent it back in, the mfg, acted surprised and sent me another one.. .Honestly even the replacement was exactly the same.. The Stock OEM battery lasted longer, and was more reliable.
Unless something has changed with Seidio since then, (which I highly doubt) I won't be "upgrading" my battery -
- I'm with the other member, I'de be more inclined to get some kinda external battery, or something. Too bad the USB connection changed on this new EVO 4g.. cuz my IOGEAR AA battery emergency charger is SICK! hmm.,.. actually i'm going to look for a USB converter, so that I can keep this iogear around.

Woah! I've been waiting to finally see the design on this as I've owned Seidio extended batteries in the past on other devices. The design on that back is a definite no go for me. It's horrific! I just can't F'up a rather well designed device with that hunchback. No way!

will people start complaining when they want 3 days of batter life? And do you guys not go home at night or day or evening (depending on when you work) to charge your phones? my phone with heavy use last about 8to9 hours.. and light to no use 20hrs.. i charge it every night..

i have the same battery used for the hero from seidio, so i hope they give the option to purchase just the back battery door. If not, i will have to wait for nakedcellphone from ebay to get his Mugen extended battery line (which have very decent door designs) and he sells em separate.
No need to drop 60 again, right?

had one for my htc diamond.. ive been checking the site everyday for that.. the back is bulky because of the battery size but like whoever stated.. you can go nearly three days without a charge depending on use.. i love those batteries

Wow. I guess it works for some. Personally I keep a micro usb cable at my desk at work. That + car charger and I'm never far from a source to charge my phone

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.
Mitchell's EVO

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?

Is that what you bought?

Yeh this seems way to good to be true. 2x 1800mAh batteries and the all important battery charger as its hard to charge both batteries with one phone.
But the pricer is really putting me off. Guessing no one has tried them yet????

Really tempted. Are these non-official batteries safe to use with the SGS2?

Hmm it looks too good to be true. I am tempted to get it though.

I just bought something like that. 2 batteries and a charger. I bought it for the charger, as I expect the batteries will be 1.000mAh max. Will buy a genuine battery when they appear someplace trustworthy.

I bought mine on....
Well from www.spider-foot.com they're very cheap and you get 3x screenprotectors for free. I think they are 1650mAh btw!

I just spent $800 on a phone, I'm not going to put some $10 Chinese battery in it so it can explode or melt - I'll just keep looking/waiting...

Search for EB-F1A2GBU and you'll find some genuine batts for 22 to 30E
That said i'd prefer having a batt + batt charger like the chinese sell, cause swapping batt to charge isnt fun, going to test it. For 8Eur, at least, the charger should be fine.. i hope

Desk stand w/extra battery bay - xda-developers

Just received my original spare battery from Export Prive. The battery is a Korean-market one, and even says "Near Field Communication" on it! Here are photos of the front and rear, the Korean battery is on the left and the UK battery is on the right.
Also got the battery charger for it. I thought it was an aftermarket one since it was so cheap, but it turns out it is an original Samsung battery charger! Also doubles as a stand for your phone.

I understand your concerns but has anyone experienced exploding or melting, I say this because I have used similar batteries on my Samsung Omnia and the i9000. Never experienced any problems and used them for over a year or so.

I purchased the same 1800mAh battery from ebay and exploding or melting is very unlikely as even the cheap aftermarket batteries manufactured in China have an integrated chip preventing overcharging or exploding.
On the other hand the 1800mAh are nothing but an exaggeration because the real capacity is around 1000mAH meaning its just an emergency solution if you should run out of your main battery while on the go rather than a real replacement for the original battery.

Andida Battery 2000mAh killed my phone .. I had to take my phone to SSC

Andida Battery it kills my beloved SGS2. Guys Please be careful and do not buy this battery
I was happy today when, I received Andida Battery. I took out my back cover and I installed the battery. I tried to turn on my phone but it did not start. So I taught that the battery must be empty, so I plugged my charger to charge the battery. But it failed to charge. I installed original Samsung battery back, but the phone did not start at all. I was so facking annoyed. I went to Samsung Service Center, I told them my phone suddenly stopped working, without mentioning the cause of damage. They checked the phone, it took them two hours, then the technician called me and he said that the battery sensor indicator chip is damaged in the main-board and need to be replaced. He said they will order the part from Korea and it will take around 2 weeks to arrival at least. I was happy that they will fix my phone under warranty.
Edited :- Real photo of the Andida Battery 2000mAh uploaded. I was so upset and not in mood to take a photo of Andida Battery I own. I google it fast and attached it on my post that why in the photo it stated 1450 mA and For Oppo a100.

OH Man. Seem like this battery does coz hardware damage in most SGS2 when installed. I think battery sensor indicator chip is actually the chip which indicate battery status level. thats why your battery stats get screwed up.

Why do you say is an 2000mA battery when on the blister clearly states that's a 1450 mA one (even less than the original). ?

I don't get it. I only see "For Oppo a100" from the pic. Is there state anywhere its for I9100?
And the Chinese in one of the label stated the battery is insured, maybe U can claim them some money.

I really hope it doesn't spoil my phone though... I rooted it so chances are there's no warranty if I bring to the CSC. I don't really use the Andida battery often anyway. It simply serves as a backup.

Thanks for clearing that up, and i am very sorry about your phone.

Hi,
I had the same issue with mine but i hotswapped that batteries around. i.e. andida to samsung back to andida and it started to work again.
at the moment i have the andida one in my phone but try swapping it around and see if there is any issues.
Q) would your phone still be covered if my phone was rooted with custom rom?
PS: and i bought two of these one for me and one for my nephew.

thx for reminding, but i prefer to buy a external charger rather than an extra battery

hi there the spider-foot battery is safe. been using it as my main battery and no problems or whatsoever since 3 weeks ago

Have been using this battery for awhile. No major issue with it. Just that while stating 2000mAH, it's not really performing better than the stock battery. Worse performing actually.
Avg after a day's use ( light usage ), the Andida's remained only abt 50%-60% juice, while the stock can still retain abt 80%.
Another quirk for Andida, after charging to 100%, when I pulled out from the charger, it'll occasionally drop to 97% immediately.
Well, can't expect it to be better since it's so cheap anyway. At least it didn't blew up on me lolz. Nevertheless, had been using the stock battery since it performed better. This Andida is just a backup for me now.
Btw, TS, just curious, did u pull out the thin film that covers the metallic contact points? I read that some pple forgot to remove this film, and they thought the battery is a lemon =p.

the only one i can rely on is the original samsung extended battery (2000mAh). It's a little bit fatter (1mm more) but great!

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

Your laptop battery is around ~15V, which is 4 to 5 times higher than the battery in the note.

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.
