[QUESTION] What would the tollerence on battery capacity be?

Say a battery is advertised @ 1300mah, how close will the actual value be to the advertised value? Im asking this because a 'premium' 1400mah battery is significantly more expensive, but how do you know your getting what youve paid for?

you have a nexus one? cause that comes with a 1400mAh battery. usually they are +/- 50mAh or so. my nokia n97 came with a 1350 mAh battery, but actually battery was 1290mah. the nexus has been said to have a 1360mAh battery for some. each battery is slightly different. read the huge battery testing thread.

HD2 Lithium Polymer Battery On Ebay!

Well guys, this would be a first:
http://cgi.ebay.com/Htc-HD-2-batter...311?pt=LH_DefaultDomain_0&hash=item3cb4d8f5af
But hold on though. It almost looks like a plain old re wrapped Li-Ion battery. The guys feedback makes me skeptical, too. Looks like he's new to Ebay.
Thoughts?

I believe its the same old crap. They say its 1600mA. But in reality even worse than standard 1200 mA. Price talks for itself.

You know I see alot of talk about these 1600mah batteries from Japan and alot of speculation, but I have never seen anyone do any real world testing. I was planning on buying one of the 1600mah batteries and doing a setcpu stress test on it as well as the stock battery and record the results of how long it took each to fully discharge.

Do it! If you become the guinea pig and the battery is indeed better, then you would be a hero in these parts lol.

The last battery I bought was a 'genuine' htc 1200mah from an amazon seller, turned out to be a fake that was obviously not htc.
Be careful with testing unknown batteries from unreliable sources, the fake one I had got very hot and was a poor fit into the phone. These phones are very temperature sensative and you would not want a lithium fire inside your HD2!

So is anyone willing to do some battery tests? I would be so happy if I could use a 1600 mAh battery and not need one of those huge, bulky battery covers.

You should be very careful if you try a battery from an unknown or not certificated source. I read about many cases, where people bought some cheap batteries which turned into a little bomb, because of some reason. and i don't know if i want to end up in a roll chair for my whole life just because of a 20€ cheaper battery. A battery can damage your phone not only by heat. Such batteries have also some extra hard- AND software for controlling purposes integrated and if there's a problem, it could cause other problems in your phone.
The normal 1230mAh battery is not very bad, one day for such a huge display and some other features is enough. and if i have to go to the jungle and can't charge my phone i will buy the bigger battery and won't mind about the thickness of my phone ^^
Just my thinkings

I actually can confirm, I can go with my phone with minimal to moderate use for several days. But when I am at work and playing with it nonstop - 4 hours maximum. That is why I got myself a GTMax battery

I would also agree with this statement. None-the-less, I ordered one of the 1600mah batteries yesterday. We're gonna have to wait a few weeks for it to clear customs however before I can do any testing.

Not the first...
I have the andida 1600 Ma and it is labeled as Lithium Polymer.

I bought a 1600 mAh labeled battery from eBay which came with very good packaging and even a tin case. The labels on the sticker make it seem fancy and trustworthy. However, in my experience comparing that battery with the stock HTC 1230 mAh battery, there is no increase in uptime. On Aondroid both batteries read 1230 mAh. Even though the 1600 mAh battery claims to have that capacity it really does not. I even weighed both batteries on a scale. The 1600 mAh Li-on battery weighs less than the HTC original battery.

It's not possible that a stronger battery is as big as the stock one. most of these people only put another label on a stock battery (or rebuild battery with the same power) and sell it for a higher price. I'm sure you won't get a Li-Ion battery with the same size as the stock one but stronger. With a Li-Po battery it's makeable but not easy and they'll have a higher price because of that.

The price makes me suspicious as well. I don't notice a lot of difference in device up time with my Andida battery, but it is still new and it may increase as I get past those initial cycles.
... if I don't reflash more NRG ROMs! They give strange readings for the first few battery cycles after a flash. I just flashed one yesterday, so it will be a while before it settles down.

The Chinese knockoff battery got here today. We're about to find out if it can hold It's own once I put it through the first few charge cycles.

It's sad that I'm able to get an 1800 mAh battery for my G2 that isn't appreciably bigger than the stock 1300 mAh, but there's nothing equivalent for my HD2.

Can't you return it. There should be eBay's buyer protectiontion just say buyer gave you the wrong item

Another Extended Battery 1600mah Question

So, I haven't looked for extended batteries in a while, Andida 1600mah only seems to be only as good as the OEM
Has anyone tried

Are they better or the relatively the same?
Appreciate any thoughts and comments

When you see it from China, consider it FAKE.

i've got the second one. i don't know if it's true that have 1600mah but for sure have more long lasting than the original

The fine print on the second one is exactly the same numbers as on my Andida battery.

Thanks guys... I don't understand why no manufacture can produce a slim extended battery. It would make the HD2 so kick ass

Is the Andida 1600mah battery actually thicker than the default battery? Seing some ebay photos it seems to me that they are the same size and there's no need for extended back cover for the 1600 batt. Anyone can confirm this?

Its not 1600 mAh. Maximum it has is 1300... Most users reported it to be of less capacity than standard one.

It is the same size, but my HD2 shows about 1230 mA when fully charged. Still, a decent price for a replacement battery.

You mean with a meter or something? My tbattery program indicates they are 12296 at full charge.

I have the 1600 mah battery and it is more powerful then the original u have to condition it first or you wont get the right amount of power after about 4 charges on it and then I had to charge the original 2 to 3 times a day but with this 1600 once a day and thats using wifi and other apps

Can you tell us how many mV you get at full charge?

This one is pure crap.
It lasts 2/3 comparing to original one and battery monitor widget shows the full capacity of 963 mah.

Whats with this?

Thinking about to buy it.
( Replace the ** , cant post Links under eight posts.

Mmm, if you want to go with big capacity & extended cover try finding original HTC extended battery & cover on a promotional offer.
Almost all of these extended batteries from China are junk with data chip sending false battery MaH data & many close to stated capacity batteries don't allow HD2 to utilise it without soft reset.
personally I went for a USB charge pack working from 4AA batteries, I loaded 4 UniRoss 2100MaH hybrio AA cells & it works great.
size is 68mmX63mmX18mm so easily to slip in a pocket or bag.
I get 2.5 charges from it, have total control over cell quality & MaH rating & it cost me less than $13 including new AA hybrio cells.
Just another option to consider perhaps.

I know a good store that sell many extended batteries for HTC, But now i cant send the link , forum cant accept that. if you are interested, send me the message.

Just type link address without www or replace a w with an asterix. Users can figure it out easily enough & copy/paste then correct address in browser bar.

I have gotten good service out of the Andida batteries. They advertise 1600, but they are actually the same output as the OEM batteries. But they are inexpensive. Some people have reported very low output from them, but that has not been my experience. Just don't expect 1600!

Question
Has anyone tried using HTC Desire HD batteries for their HD2? I just ordered these HD2 batteries that are 1350 mAh on an eBay store located in Brooklyn. They are 2 for $8, I figured worth a chance for only 8 bucks, but I'm still thinking 1350mAh still won't be enough. The HTC Desire HD batteries are 1500 mAh and almost look like they'd fit, but I'm unsure. Right now I'm running my HD2 on the Desire Z ROM that is rooted, I think it's made by Dandiest and Freak. This ROM is seriously the best out of the 3 I've tried. With it being rooted I was able to download the battery calibrator on the market and it has increased my battery life significantly. I'm still on the standard 1230mAh battery and I charged it to 100% and unplugged it at 8:49 AM and it's now 8:28 PM(I'm in Germany) and it has 40% battery. This is just mild usage though. Any suggestions, or anyone know if the Desire HD batteries would fit and work?
Please Help

HD2 extended battery, same size like original

I would like to buy extended battery that is same size like an original so it wouldn't stick out...
I have read few threads about that and I know that there are few 1800mah batteries which are really just fake 1270 mah...
So...what is max capacity in original size?
Thanks

15000mah Mugen is only option for same size & real stated capacity.
reality is a different battery technology would be required to better that.
www.mugen-power-batteries.com/mugen-power-htc-hd2-t8585-1500mah-extended-replacement-battery.html

As above, there is little in the way of a regular sized battery with considerably more capacity than the stock battery. If you're looking to keep the slim look then I'd consider doing as I did and investing in either a cheap 2nd battery (either used genuine or cheap Chinese) off eBay for a couple of bucks. coupled with a battery charger which charges both the second battery and the phone, im yet to find a situation where im without power.
Sent from my HTC HD2 (Android)

my solution to lack of capacity was to use a usb charger pack running from 4 aa cells (2100mah hybrio cells) & mod pack to activate 1Amp charger mode.
cost less than $20 & is easier than swapping/booting & externally charging hd2 batteries.

I'm actually selling my barely used 1600mAh battery on eBay (link here). I used it for about 10 days before the touchscreen on my HD2 went bad. No added bulk and the battery life is about 30% better than the original battery. I bought it from a seller in Hongkong after reading a HD2 user's suggestion here. It's about 10USD if buying from China, delivery will be from 14-30 days.

And what capacity does T-Battery application show this battery at ? for sure not 1600Mah ...

Oops ... double post ...

There are two type of good batteries momax or mugen. (Even the fact that both companies have an own website says already a lot).
Muggen has higher capcity while momax uses better cells according to 6 pages of user experiences. Both will preform about the same like 20% capicity extra. I would go for the momax since it works better in android (capcity is close to orginal one) and it is a bit cheaper 21-27 usd according where you buy it.

Momax X batteries are produced in same factory as Andida.
The momax HD2 replacement battery gave me no extra usage time, if anything less.
It may give 20% extra capacity if compared to a 2 year old fatigued OEM cell but new next to new OEM wins hands down.

If you say so...
My experience is different anyway and from a lot of others to and I can't use any battery wich has higher capicity then the stock one because it wont work well in android.
Also andida battery come from:
http://www.laishenglong.com/en/
And I am almost sure that they are not made in the same factory andida battery's look more like fake clones.
But maybe you can show me some evidence.

That was what I was told by a dealer in Hong Kong when I purchased a Momax.
The reality is a battery with less Mah than stock is not going to be 20% better but they are ok & give reasonable performance & quality for the purchase price.
Andidas registered address is Hong Kong as is Momax but neither have factories in Hong Kong.
The Andida & Momax X batteries & packaging are identical from what I looked at in Hong Kong. The Momax HD2 battery is not the X series & is different in battery wrapping, labelling & packaging.

Is buying the battery on ebay smart?
Where should I buy it to know for sure I get the battery/capacity I want...

What capacity do you want & do you still want standard size ?
The only battery that I have seen that is really higher capacity & sized same as original was a Mugen, all others read standard Mah rating when tested with tbattery.exe.
The chances of getting a higher Mah standard size battery off eBay is probably zero. A work colleage purchased an Andida 1700Mah from eBay seller snow9white for a TD2 & real capacity is 1100Mah, but ok as at just under $10 inc shipping he was happy as performs as good as OEM & he already was aware of Andidas overstated capacity.

I've read something about better cells and no need for higher capacity...so I don't care about capacity really...all I need is more time between charging it...
But I don't want to buy something on ebay, if I am not sure that it will be better as the one I have now...
The only thing I want is battery in original size that doesn't sticks out or need extra battery cover...

More time = capacity. quality of cell will have some link to overall run time but the main issue is capacity.

Yeah but I am not talking about the stock momax battery I believe you if you say it preforms the same as stock..
I am talking about the 1250 mah x-level variant.
Before you have only the stock variant since like 2 months there is the x-level variant for like 21-27 dollar.
http://www.momax.net/en/Product_Show.aspx?ID=1303&T=1

Yeh I bought mine about 3 months ago & is not x-level model cell, no HD2 x-level at that time for HD2, will have a look for the x-level HD2 in Hong Kong & if sensible HK$ buy one for a test.

Ok which one is better? The Momax X-Level or Mugen Power?

Is the Mugen worth almost double the price?

Mugen should be the best in terms by capacity & quality but with the price diference between the two it makes the x-level a major player.
I will be going for an x-level as price direct here in hong kong is just too good, don't really need one but want to test it and see if they are as good as current hype.

Ok guys, I just got the X-level battery today, I'm charging it right now and post later on how well it is.

is this battery fake????? (picture attatched)

hey guyz
i bought this battery from ebay with 2600 mah
is it fake???
and if it isn't how could i calibrate it (am using android from nand)
sorry for my bad english

Well chances of it being 2600mAh are unlikely, if lucky it maybe 1700mAh.
Also kernal of your ROM need to be capable of handling over capacity batteries, for that refer to your ROM thread.

ahaaa. ic
thanx buddy for ur quick responding
i should buy 2300 original......

I have the extended battery just like this. It claims to be 2300mah and after a few cycles my battery widget says its estimated to be 2300mah (with 30% margin of error).
All extended sized batteries I've tested have shown to be over 2000+ mah and have given me more than double standby time.
If the battery is standard sized and claims over 1600mah then suspect BS.

Most of the cheaper oversized batteries tested by members on XDA came out at 1700mAh.
Peeling the sticker will lead to the truth.
Is a thread on this with a selection of oversized batteries & the true capacities.

Well I have owned 5 extended batterys in my time.
2 for HD2
2 for WildfireS
1 for Dash
All of them costed below £10.
All of them had seen my phone pass 30hrs.
My typical standby with normal batteries is around 11hrs.
My WildfireS extended bat topic.
forum.xda-developers.com/showthread.php?t=1296297

Going from OP supplied picture of of black/silver label style found on eBay & amazon most are tested well below claimed mAh
I have tested many myself & delt with resources in China that make them.
From 11hrs to past 30hrs is 3X over standard, that would equate to 3000mAh plus, no chance of 3000mAh cell & cover for £10.
You get what you pay for & when it's Chinese products & eBay/Amazon getting what you pay for is a gamble with poor odds.

so how could i calibrate it??????????

You have to account for night time which is about 8 hours of no activity meaning little drain.

Thats fake around 1700Mah i guess
