Stop the debacle and concern on whether or not the 1700mah, 1600mah 1500mah blah blah blah batteries are better than stock.. I have a LOT of experience with Li-Po and Li-Ion batteries (cell phones use Li-Ion technology) and I can tell you WITHOUT a doubt that all these knock off companies are full of SH^* trying to say there batteries are of a higher capacity than the stock battery while staying the same size. Although it is possible to cram more mah into the same size package with li-ion batteries it is VERY unlikely to be able to do so with the current technology out right now. Most of these companies rate their mah on a different scale and actually will pull the battery to a lower voltage to justify their claims when it dosent matter because cell phones have a safety feature that has to shut the phone down at the specified voltage to prevent fires. Yes fires, Li-Ion has a fire risk if it is depleted all the way, not the same risk as a Li-Po battery but a risk just the same. HTC has a separate department that deals specifically with batteries and I can assure you they know and use the most up-to-date batteries they can get their hands on for these devices. There is nothing for them to gain by using inferior batteries in our phone. Those that have purchased the seidio 1600 extended battery and claim to have a better life on the phone are under a placebo effect. If you are just purchasing this "Extended" battery as a spare than buy all means go right ahead but dont expect a miraculous two hours extra from it because it is of lesser quality than the stock battery. I have hundreds of dollars in battery testing and logging equipment and If you guys dont believe me i will run some tests on the stock vs. whichever battery you'd like me too and post the data for all to see, but Ive been down this road before with htc phones and have always come up with the same conclusion......The aftermarket "Extended" batteries actually have less mah's than their stock counterparts.
Of course Im not referring to the htc extended battery in this post, its obviously pushing more mah's with its monstrous size, lol.
....just sayin..
Oh' and to elaborate because Ive also read some concerns over the length of time for charging the thunderbolt (which does seem lengthy I will admit).
Since our phone has such a hard time time keeping up with a normal days use I believe what htc has done is given the battery a longer "saturation charge" for the battery to completely charge before it completes the charge cycle.
Li-ion batteries are charged on a 3 cycle charge system and stage two is what is considered the saturation cycle where the battery may sit at a relatively static voltage for a period of time to saturate the cells with current to top off the charge, some cell phones skimp on this step to give the phone a fast charge time which is termed "charge-and-run" and people assume the device has been adequately charged when it has not. For an adequate "FULL" charge without harming the battery or affecting battery life, typically li-ion batteries take approx. 3-4 hours.
So the 3 batteries I got for 12$ on ebay ARE paperweights?

I wouldnt go that far, I doubt any of the batteries are "paperweights" yet. Im just making the point that the claims of higher capacity are unfounded and the cheap knock-offs are of lesser quality. Also check where the batteries are made. Good quality Li-ion cells come from Japan.
One thing to note with the cheapies is the temp while charging or under heavy use. Get a temp monitor app and compare between the stock and your aftermarket batteries, they will probably run hotter. Unfortunately I dont have any other batteries to test for you guys other than the stock OEM battery otherwise I would. If I pick any up Ill cycle the stock vs. aftermarket and post the data log between the two.
Also I didnt mean the "fire" comment to worry anyone, Li-ion batteries have protection curcuit that will render the battery useless and unserviceable if the cell reaches a voltage of 2.70v or lower which is where the chemistry of li-ion becomes unstable.
I'll ship your one of the two 1700 when I get it if you wanna test it and post results. Just ask that you ship it back after your done.

ha, I bought the same ones you did.
I didn't expect them to be as good as the 1400 mAh battery that comes with the phone. I just wanted to have a spare battery available in case I'm traveling and watching movies or something (on a plane). Even though it says it's 1500 mAh, I expect them to be more around 1200 - 1400 mAh.
Check this website for some information on similar battery testing.

I used their results when I purchased the Seido 3500 for my Evo.
I've used Chinese batteries every chance I get. They do work. From an Eris to the Dinc. 3500mah. Never had a problem. Emails and games etc. I bought the extended battery along with the Tbolt. Just don't like the hump on the back. I'm on eBay every night waiting for the Chinese to strike with a extended battery. At least a Better extended back cover. For $10.99 free shipping ill wait 2 weeks for it. F%$% what u heard their cheap batteries work.

If you do I recommend you buy the 1500 MyTouch4G batteries from ChiChi's htcexpress or their store on amazon. They should be the same a the 1700 Thunderbolt batteries and $20 cheaper.

When I get around to ordering up the batteries Ill post a chart like that on a seperate thread for our phone. I have some pretty sophisticated logging equipment. It shows the temp, charge capacity, voltage, mah, cell balance and health in an easy to read graph.
Im not a battery nerd but I used to be into RC helicopters BIG time and when you have a $5000.00 helicopter that can kill someone its just normal practice to have the equipment to check your $800 batteries so they dont fail 80 feet in the air and blow up or decapitate someone, lol
Heres a video of one of my helicopters (Trex 700 electric) , this one uses two 6s 5000mah li-po batteries and each one costs over $300 and they only last 8 minutes before there dead The video isnt of me however, I need a video camera to post mine but the helicopter is identical for the most part.

(speaking from g1, nexus, and g2 experience only)
i've bought extended batteries for phones for less than $15 each all in the 2400 to 3600 mah range. they last 2-3 days with normal use. the oldest one is 3 years old (g1) and still performs like new.
iirc the seller was based in hongkong.
just saying.
the htc extended battery
personally of all the batteries i have tried this is by far the best one until sedio has an 3500mah then i will be getting that i think

Could fry your phone as they state that you shouldn't use "inferior charger" lol. They'll blame your broken phone or battery on the charger.
And I bet it is no where near 2300mAh..... So many cheap batteries state they are, but in reality they are no where near the capacity they state.
I bought some cheap Chinese batteries knowing they woiuldn't be as good as the original battery even though they state 1800mAh. And guess what, they are not as high a capacity as the genuine battery, probably closer to 1000mAh of gut feeling. But they are only for emergency use because I do not trust them a lot so try to reduce the risk of them ruining my expensive phone, more for leaking or exploding rather than high voltages (because high voltage is not really possible with the chemical nature of batteries). And I never charge them in the phone in case they explode.
I have read that a lot of these batteries are in fact smaller generic batteries and all they do is put an external case on them to make them fit different phones. I wouldn't be surprised if the one you linked to is the same battery as mine but with a different sticker.
How risky is it to use non-oem batteries that can be found on eBay?
In most cases, it's fine. I have several non-oem batteries for my g1 and they perform about the same. However, if you don't want to risk a battery explosion and possibly death (in an extreme case), it is best to stick with an oem battery.
i bought several for different electronics. only issues i had was either it being doa or slight bursting. the slight bursting was on a smartphone and only happened once which was 3 years ago when the phone had overheated.
I think you'd probably be okay, but i'd avoid really dirt cheap batteries from Chinese sellers on eBay - there are a few reasonably well known 3rd party companies that are cheaper than OEM but still trustworthy!

This. Never cheap out (quality wise) on your phones battery! A low quality battery will not hold it's charge well, and could pose a harmful threat. You shouldn't risk your phone (or yourself!) over a cheap battery. If it's significantly cheaper than any other battery you can find, be cautious.
They don't usually cause damage to your phone.
The problem with brand x chinese batteries is the mah ratings are usually just made up numbers. When tested the actual mah are often much lower. Sometimes less than the stock battery from the phone oem.
yeah personally i dont like to use aftermarket batteries after having one explode on me on my old Moto Razr.
Avoid very cheap batteries, they tend to die quickly.
i advise you to use Anker or Mugen batteries.
Best to use the OEM ones, less likely to explode and work best with your phone.
Also, if you do get third party batteries and they do explode, then you probably voided your warranty and can't claim.
Don't expect longevity or high performance, but they will do temporarily. Just a warning from experience, some times those cheaper batteries will cause your phone to not measure battery consumption as accurately.

Hi, i am curious to know as recent found that a new technology for battery improvement -> Lithium Polymer (Li-Poly) Batteries. Is this kind of battery ready to launch for Samsung Galaxy S2?
Source : http://www.puremobile.com/cell-phone-batteries
Is this a joke ? There are Li-Pol batteries since 10 years and maybe more.
They are more expensive and they lose capacity faster than Li-ion batteries. But in our eyes, potential environmental concerns are significant as well. Most Li-poly batteries on the market today require some fluoropolymers in the matrix. Fluoropolymers are expensive and difficult to create, requiring a lot of energy and chemicals. And, most troubling, there are currently no good programs in place to recycle lithium-polymer batteries.
Li-po batteries are around for a while.i have a sony w995 with a li-po battery n the battery is amazing but dont think phone manufacturers gona use this option since it comes with alot of downsides.

Hang on a minute.
Most, if not all replacement batteries are Lithium Ion.
However, the official batteries that came with all these phones were Lithium Polymer. Why?
- i9000 (Samsung)
- VT610 (Motorola)
- W580i (Old sony ericson)
According to here:
http://www.brighthub.com/engineering/electrical/articles/123906.aspx
and also here:
http://www.androidauthority.com/lithium-ion-vs-lithium-polymer-whats-the-difference-27608/
Lithium Ion is the better technology and also the cheaper technology. It should last longer too.
So why are mobiles shipping with lithium polymer? It's anecdotal but I find polymer to be a bit better in a new phone...
It could be because Lithium Polymer can be shaped more easily? But why can't we buy a replacement polymer battery that (for example) is shaped as the new back? The current back cover replacement batteries are simply a block - not a L shape sculpted to the phone. I notice there isn't a single polymer battery available from China
Confused...
I have a feeling this thread is just one of those spam bot things.
Trust me you don't want to use lithium polymer at the moment. they are highly unstable especially if there is a big enough voltage drop across the cell(s). Basically if there is a big battery drop across a larger group of cells it can cause a major exothermic reaction.
THAT MEANS FIRE AND/OR EXPLOSION!
This is why there was a recall on a a lot of those toshiba laptops when the technology was first released. I had heard a rumour that it was in some phones a few years ago and they stopped it and recalled the batteries instantly for fear of massive explosions and facial injury.
There might be video somewhere of it even? I went googling it a while back when my mate had a little remote control helicopter for indoor use only and it used lithium polymer batteries and charged via USB cable! Thing was so cool However it caught fire when were flying it and pretty much turned in molten ball of hot plastic goo before it hit the floor. It nearly caught the lounge room on fire and ruined the carpet in the rental place he was living in.
They also use this technology in the new brushless RC racing cars and I have heard good news from this group of people. I asked recently and one of the guys in to racing mentioned that they have improved batteries considerably! However he also mentioned that there are explosions from time to time. Any explosion is enough to warn off phone vendors

My Galaxy s2 came in with a Li-Ion Battery..
Lithium Polymer batteries are indeed highly unstable, or have the possibility to do so. I fly electric radio control helicopters, which uses li-po batteries, and it is recommended to use a battery fire-proof bag to enclose the batteries while charging.
I certainly want something to catch on fire or explode while in my pocket...

Hey guys! So i posted smth abt Bloated Battery and u guys told me to change it. Surfing the net when i came across this online shop that sells 2480mAh Battery for the Galaxy W (and others) and i wonder whether its real cos' i dont think such small slim battery can that much mAh rite? But also, its made in Japan NOT China so i expect to see "quality" here
check the one in my signature, it's exactly the same
i cannot compare it with stock one because stock one behaves badly after some overheats and experiments
everything is chinese but mine imho is quite nice, got 340 antutu battery score with it
the screenshot in sig is also made using it

So it means, the mAh on the "Gold" one is exactly the same (1500) but behaves somewhat more better than stock?

don't have any equipment to exactly measure the mAh, possibly it's about stock one
feels nice to replace damaged stock one but seems not to be a variant for super upgrade

or any method to measure the stats?
PS overall i'm satisfied, it's worth it's 7$

This is the ultracheap golden one I was talking about in the other threat where you asked about freezing your bloated battery.. Having here 2. Each for 5 Euro.
So well. This batteries never ever do have this capacity. Somwhere around stock capacity or a bit less. They do not last that long like a Samsungs battery, so you will have to reacharge it a bit more often than a new Samsung battery. It´s even a bit thinner than a regular 1500mA battery.
However there is one advantage in using it. It´s a LI-Polymer battery. Not a Li-Ion battery. So it doesn´t use an fluid but a polymer and therefore the risks to get it bloated are much less than with a LI-Ion battery. I ran them also really hot and they didn´t get bloated so far.
When this battery would have about the same thickness like the Stock Samsung battery it really would offer more capacity but thus it´s thinner it has just about the same or a bit less and the 2480mAh are just fake.
So well you can use it as an replacement. Just don´t expect it to last longer than a stock battery.

That´s nonsense. The polymer is a static foil which can´t boil and create gases like the fluid in LI-Ion batteries. Well you can make everything explode. Even a banana by sending a flash with thousands Ampere through it.

Sorry but there you are wrong.
The difference between them lies in the material used as the separator. Rather than an inert substance with holes covered in electrolyte, the separator is made of a micro-porous polymer covered in an electrolytic gel that also serves as a catalyst that reduces the energy barrier in the chemical reaction between cathode and anode. Therefore, Li-Polymer batteries allow for a slight increase in energy density.

Risks and limitations on li-polymer battery:
1) Overcharging a Li-poly battery can cause an explosion or fire.
2) During discharge on load, the load has to be removed as soon as the voltage drops below approximately 3.0 V per cell (used in a series combination), or else the battery will subsequently no longer accept a full charge and may experience problems holding voltage under load. Li-poly batteries can be protected by circuitry that prevents over-charge and deep-discharge.
3) Compared to the lithium-ion battery, Li-poly is less advantageous in terms of life cycle degradation rate.
4) Lithium polymer-specific chargers are required in order to avoid fire and explosion.
5) Explosions can also occur if the battery is short-circuited, as tremendous current passes through the cell in an instant. Radio-control enthusiasts take special precautions to ensure their battery leads are properly connected and insulated. Furthermore fires can occur if the cell or pack is punctured.
6) While charging the lithium polymer batteries, the individual cells in the pack should be charged evenly. For this purpose, the cells are to be charged with special chargers. This entails special care while charging the batteries in addition to incurring expenses on procuring the chargers specific to lithium polymer batteries.

2480mAh?? do a search buyers claim it to be below 1200mAh.
google search the 2900mAh battery, thickness is double, this is many claim to be the true deal.
china have many rejection parts from corporation companies, their sub-contractors to sub-sub contractors to sub-sub-sub small companies.
many will recycle to gain back some of their loss $$$ on rejections instead of dispose/destroy those parts.

Its okay really, we can somewhat "compare" with the OEM battery (but since mines bloated ) and "gold" one in an Antutu Benchmark test... Who knows?

very easy
someone with stock battery performs the test and compares to my screenshot
anyone can?

lets return back to the main topic.
it is too cheap compare to oem battery, so dont expect goods specs be accordance to wat it advertised.
it cant be li-polymer battery, too expensive to manufacture.
2480mAh?? do a search buyers claim it to be below 1200mAh.
google search the 2900mAh battery, thickness is double, this is many claim to be the true deal.
china have many rejection parts from corporation companies, their sub-contractors to sub-sub contractors to sub-sub-sub small companies.
many will recycle to gain back some of their loss $$$ on rejections instead of dispose/destroy those parts.

Oh wehhh. All the disadvanteges you are listing up in your previous post are also related to LI-Ion and every other battery.
Like I already said. Overcharging a banana with a flash will make it also explode. A flash hitting your head will also overcharge you. It can make your eyes explode and will boil your blood imediatelly. Why do you think they are bounding the eyes for people who are getting killed on electrical chairs? Because their eyes are exploding when the current is streaming through their body.
The same to short circuit a battery. Even a silly carbon battery will explode under this circumstates. That´s also why most batteries used for phones are having a short circuit protection. Even the old NiCd batteries which were used in the stone old cellphones.
About droping below 3V. This is legit for both. LI-Polymer and LI-Ion. Not only to LI-Polymer.
LI-Polymer batteries are charged the same way like LI-Ion batteries. The source telling it needs an special charger is a guy who is just sharing his opinion without referring to fundamental sources.
The other source is from 2001 and rather outdated when it comes to density but even there the guy says it´s less dangerous to catch fire.
To sum this up it seems like you just are collecting contrary claims like the guy in your first source without being objective just to make this type of battery to appear worse compared to the older LI-Ion batteries. But not telling the full truth to make it appear like LI-Polymer can explode when overcharged but LI-Ion can not. And this is for me bending the truth.
And to be exact. Not Li-Ion battieries began in 1912 but simple non rechargable Lithium batteries like the one used in watches. Rechargable LI-Ion batteries began in the 70´s and Li-Polymer is the further developement of LI-Ion batteries where newer manufacturing processes and developement make it even safer and having a higher density.
So last but not least. It IS a LI-Polymer battery. It has no hard case like Li-Ion batteries require to have to hold the fluid in it. You can bend this battery forth and back like all li-Polymer batteries. On the back side it even says it´s a Li-Polymer battery, but the missing hard case and the bending test are enough evidence for being one.
AND it has been said already many times it´s never ever 2400mAh but somwhere around stock capacity. The is just fake to get better sales.
However for this money there is nothing wrong in buying it as an replacement.
