If u buy batteries from good brands they shouldn't harm your device... Just check the product. . There are enough and more reviews on you tube about replacement batteries. .. look at them and choose one... personally after rooting and using the brilliant ROMs made by devs here , I've never needed an extra battery :thumbup:

because they're not. The manufacturers are just lying to get more sales out of it, it's not like they have a reputation to defend

The power/size ratio for Li-ion is fairly linear, it isn't possible to get a greater mAh rating without also increasing the physical thickness of the battery. Sellers claiming 2850mAh in the same package as standard are actually selling you a normal 2100 (or less) battery. These types of seller are unlikely to worry much about the correct safety devices the battery should contain - Lithium fires are really bad news.
If you need a greater mAh rating, buying it from a reputable seller, then you'll need to get a new back cover for the hunchbacked profile your phone will have.
Instead I have two normal batteries and swap them over with a desk charger when empty.

You can buy normal stock batterys for the s3 from any phone store. Bigger capacity batteries (otherwise known as exteneded batteries) provide longer battery life providing your kernel doesnt prevent your phone from using more than the stock 2200 mah. Typically batteries bigger than 2700 mah will require a modified back case which you buy with the battery. Because it adds a little bulk to it

no, batteries bigger than 2100 mah require a custom case

HTC MAX 4G T8290 battery on HD?

What are the chances that the 1500mAh battery that comes with the MAX 4G would fit into our Touch HDs? The MAX is slightly thicker than the HD which may explain the bigger battery though..
Yeah that would be nice... I wonder if the battery connects are in the same place. If so the battery may work but probably bend or bulge our battery cover.
Another problem is where do you buy the max 4g battery from?

No chances, different dimensions. I see them.
That sucks. I was wondering the same thing.
heyhey,
I am from Hong Kong, and I got my HD yesterday.
I also bought a replacement battery incase my HD runs out of battery~
I think it is a Japanese brand, and the battery comes with 1500mAh!!
google it and u might find it!
~cheers
Got myself a 1500mah battry from ebay.
It fits and works.
was hoping for an even bigger battry, cause the difference between 1320 and 1500 isn't that much.

May I know the brand and how much is it?
Thanks!
i bet its momax. its HK brand. im using it. also 1500mah. not longer than original one.
but its ok to be a replacement....so far so good
Gotta be careful with batteries of unknown sources.
Surely there are many good and cheap stuffs made in China, but more often you find cheap and bad items.
From my experiences, these low price batteries are short-lived, with wrong mAh parameters, and worst of all, may cause damage to your precious phone. I'd better buy an original one (or wait for it to appear...)
I'm also using a second 1500 mAh battery from eBay without issue. Does last longer than the original 1300 unit as I can compare because I swap between the two on extended trips away from the office.

Same here... no picture posted yet, but i am sure it is going to be a very big one indeed.
It says it is 2.5 times more powerful than the original.
Though could be very indispensable for summer travellings and countryside picknicks far from civilization, but still to enjoy connected and secure feeling
Well, the 1900 mah one works great so far. It's quite possible that it will work as advertised.
Dang I'd buy it if it were in stock

The OEM Extended battery is big enough and I believe that was 2700mAh? I couldn't imagine how monstrous this thing must be, even if they do find a way to slim it down.
I suppose they could pull it off if they punched more holes in the layers and stuffed in some silicone. They'd be able to make it nearly the same size as the original OEM battery. I just don't think battery companies are doing that yet.
That's one enormous and expensive battery there. Having the oem extended battery, I don't know if I could take a much bigger battery, but it would depends on exactly how much bigger we're talking. The oem one gets me through 98% of days with absolutely no problem. The price would have to be a major consideration as well at almost 100 dollars.

wow epic battery life. Lol. My OEM extended battery lasts my just about 48 hours, I could only imagine how long that one would last, idk maybe 72!

I hope Mugen comes out with a battery that lasts a full year without recharging. I would pay $45,000 for it.
I wish they wouldn't charge so much for extended batteries.

lol it would be the size of a small horse! maybe you could ride it to work..............
i think we're getting somewhere...
That'd definitely be useful for people like me who love to run their phone at full speed and full brightness, but aren't near a power source most of the time. I only use my extended when I know I'm going to be out for awhile since it's such a beast, I can't imagine how huge this thing is going to be!
I just put in an order for mine should be here by end of april
Are they trying to bring the bagphone back? That's gotta be ginormous.
Thanks! gonna order a 1900 as soon as they are available
I ordered a Mugen Power 1900 mAh battery from a reputable vendor on ebay. It shipped and should be here by Thursday. It was even a few bucks cheaper than what the Mugen Power website was selling. They have over 10 of them in stock, according to the listing.
I also ordered the Mugen Power 4000 mAh battery from their website. It won't ship for a few weeks since the battery is on backorder.
I hope to do some comparative tests, like I did for my old Droid Razr, as well as a video review. But that will be next month, likely.

here's to hoping it's just creatively shaped... I feel like there's a lot of unused space behind the extended battery cover that a manufacturer could take advantage of (albeit a bit costly...)
UPDATE: Mugen says 4000 mAh battery is strong enough to power your car. Details here: http://www.thatbatteryistooEffinbig.com
how does this battery compare to the normal extended battery? would it fit in the case for the extended battery?

Dunno, 4000(mugen) - 2750(oem) = 1350 advantage(almost a standard battery) ...no pictures as of yet for size, but trust me I'll post a decent review when I get it sometime either this month or next. When ever the hell they get it to me.

Edit: math is off, I've been up for 30+ hours its 1250 advantage

Note 3 slim extended battery and other extended batteries question

I have 2 questions as followed:
1. Anyone here knows a slim extended battery that is better than original manufacturer Samsung battery ? By this, I meant better in real life, not on paper. I know a lot of batteries claiming 4800 mah but their performances are horrible.
2. Anyone can compare Hyperion vs zerolemon vs MPJ extended battery in terms of thickness.
Thanks so much.

1. Without a huge advance in battery tech since the time the N3 battery was designed, it's not possible. I am not aware of any such advance available to consumers, so any claims to have more capacity but be the same size are likely BS.
2. Most extended batteries will be about the same thickness, they are usually a second cell stacked on top of the main one. The ZeroLemon is the same, but instead of 2, they have 3, the top 2 are offset on top of the first one that goes inside the phone. So the thickness is about the same for all of them. The ZeroLemon will be heavier though. Partly due to the extra cell, partly the nicer case it comes with.

I don't think ZeroLemon has the single cell batteries available yet for the Note 3. When they do make one I might get it because the charger they give you has a USB port on it you can charge your phone with from the battery that's installed in it at the time which is a nice feature to have.

Battery Xperia U 2450mAh High Capacity

Hei guys, not to advertise, but I found this battery, is only 7 dollars .. the shipping is free. For all those who want to try it http://www.eforchina.com/view/16274...usiness-Battery-for-Sony-Xperia-U---ST25i.htm
Same size, Larger capacity. Not possible.
Made in china with a bundle of comments about how awesome it is. Not possible.
So sorry, but 90% chance that's its fake.
How ever if you do buy it and notice some change, then feel free to mention. In interested.

I'm hesitant too. Personally I do not want to try, as regards the size it is natural that must be the same, does not mean anything. The site is reliable (I have already bought there), however I think that really has the potential
size is proportional to capacity

sorry I do not understand much, but a larger battery will not automatically compatible with the 'XU, by force must have the same dimensions. There are really isometric batteries with more mAh capacity (known brands = higher costs)

bought this one off dealextreme last year, no difference with the original battery and seems to get progressively worse quite quickly

By cutting corners like margins for thermal & gas expansion you can squeeze a little more capacity (a 1,8 Ah battery instead of a 1,5 is realistic, although often it's just a fake)...
But as you said an hypothetical better technology will likely be more expensive (and regardless of price you'd only be able to see it in batteries for Samsung S2, S3, S4 and very little other phones )
This all in theory as no brand batteries are often an outlet for dumping subpar cells (which will probably end up being compared to a high quality but worn out battery so they can indeed be better in the short term), anyone can design a plain label and/or change the firmware to make it report a different capacity...

Hi,
what do you think about this :

is this safe?
I have buyed this battery 6 month ago for 4 € and... it's fake. But it's safe and a good second battery.

Solar Panel Power Bank External Battery

Tried searching but search is down or something as it gives error.....
Any experiences with using these?
10,000 or 30,000 mAh versions?
the 30,000 version don't seem to be proper 30,000 though but are they still better than a 10,000?
they are roughly the same price on ebay and look the same.............
any suggestions as to any other SPPBEB's?
Thanks
I use an assortment of Ebay and other sourced battery packs. On some level they all lie about the capacity or they forget to mention the loss you get on the poor cables they include.I have resorted to carry around two or more battery packs ranging from 6000 mAh to an Ebay special 20000 mAh I suspect the last one is not more than 10000 mAh but they all work well enough. I prefer to have a few at hand as to one large one. When traveling you may use up the large one and your device but only have once charging point.
How to buy 10000 mah?
