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

Mugen Power 1800mAh battery for htc mozart

Just started using a mugen power extended battery and am getting a lot more use out of the handset, haven't cycled it the recommended 5 times either, so expecting a little more juice as time goes on!Recommended!

Hi judd5000
Good to hear !
I have ordered the 1800 mAh battery from Mugen, hope it will arrive soon.
As soon as I get it performing properly after the correct cycles, I will post my feedback along with phone settings used.
cyb0tr0n

i hope this battery would fix the problem of original battery

I got mine yesterday - even the residual power in it got me through a whole night with GPS on and two email accounts checking once an hour. So far today after first full charge the battery has dropped a little since this morning but is still at about 80% and has been so for at least 2 hours. This is with light to medium use, though I did go out for an hour or so and had to switch from wi-fi to 3G, and I live in a terrible signal area that kills batteries, so so far I'm impressed. If it improves even more with a few more conditioning cycles I think 2 days will be within reach.
Also, and why this would be I have no idea, I seem to have a slightly better signal reception too. This is probably coincidence though, so don't take too much notice of it!

Is this the same size as the original battery or is it bigger? If so do you need a new back cover?

exactly the same size

Got just over 30 hours from mine today with light to moderate use, mainly on WiFi but in a bad signal area. And that's just the first charge/discharge cycle so there's more to come. Impressed!

OK, final verdict - the Mugen 1800 mAh battery is much better than the 1300 mAh stock battery and well worth the investment. Once properly conditioned, 24 hours with moderate to heavy use was easily done (GPS on, 2 email accounts on hourly check, an hour or so of newsgroup reading, 1/2 an hour of gaming, an hour or so of web browsing, 1/2 an hour or so on the marketplace, a fair bit of texting and a 20-min phone call in a bad signal area). With fairly light use (email accounts on manual, a few texts, just the occasional 5-min check of Twitter/Facebook and brief web browsing), I've managed over 40 hours and I suspect 2 days is well within possible - I tend to leave GPS on out of habit and have brightness on auto. Knock the GPS off and have brightness on low and that'd save a bit more again.
Obviously having a smartphone you don't use a lot of the functions of isn't ideal, but if you go away for a long weekend and forget your charger, it's good to know you can make it through (if you have the right battery!).

just ordered one.

How much is it?

I should mention that charging time is long... I recon at least 2 hrs for from 0% to 100%.

Is there a way to get a performance comparison between the Mugen battery and this GOLD 2430MAH Japanese one? Thanks

2430mah? so almost DOUBLE the capacity of the original battery, but the same size?!
That's actually physically impossible. If you're lucky this fake "Gold" battery is 1600-1800mah.

50% better than original...

I am afraid all these batteries are produced in Asia, Mugen included. If we assume the Japanese one is truly Japanese, perhaps this latter is better, but I doubt it, due to its unrealistic capacity.
Given the obvious environmental concerns related to the manufacture of batteries in China, I certainly prefer to wait until some good alternative is provided by a German company (usually very efficient in these jobs). ATM there's nothing convincing on ebay and amazon.
If you are in Europe this involves in addition having batteries shipped within the EC and no extra customs' costs!

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?
http://www.mugen-power-batteries.co...585-1500mah-extended-replacement-battery.html
http://shop.momax.net/?sp=&p=6&cat2=635&cat1=113&cat0=46&id=3396&cat1=113&cat0=46&new=&more=&lang=en
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.

Highest capacity of battery

Hi all,
I would like to buy a same size as ori battery with highest capacity available in the market now..
Anyone know where could I get it? What is the battery capacity? And lastly what is the price range? Thanks ya.. I'm searching for it as i donwan to charge my phone twice a day.. quite irritating..

there are a few ebay sellers who sell the genuine htc battery. just search for "genuine htc ba s520" on ebay. most are based in uk. all around 15 - 20 gbp.
you will find several chinese aftermarket batteries claiming higher capacity than the 1450mah of the genuine battery, but beware. none of them (i've tested a few) actually last longer than the htc battery, in my experience. and i don't know if the quality can be trusted. they do cost a lot less than the genuine battery so it is a cheaper option.

u can try dc mugen

I want higher capacity battery so that my phone last longer between charging.. not HTC ori battery with same capacity.. thanks ya..

If it would be possible to put more capacity in the same size battery HTC would have done that from the start, you're only option is to get one of those fat 3500mah batteries from ebay with a thicker battery cover, i'm thinking of getting one of those, unfortunatly i can't put a silicon case around the phone then ...

is anyone aware which is better battery among the custom makers ?
Will be great if that is available in India .

SEIDIO SUPER EXTENDED LIFE BATTERY FOR HTC INCREDIBLE S

extended battery/door
Thanks mate, I'll take a look.

I've been using the previously mentioned Mugen 3700 mA extended battery (larger, yes, but I'm used to it already) for 2.5 weeks now.
I've completed calibrating and conditioning the battery thru the 5 discharge cycles as instructed, followed by some of the lore I've sifted from xda. It's been useful.
I used to charge in morning and had to be careful not to use my phone too much and need to charge again in one day if I used it a fair amount. My incS was used, so stock battery probably had wear.
Now I get two full days of moderate-somewhat heavy use, and very far into the 3rd day if I use it just for (many) texts and a few short calls and it sleeps half the time or more.
E.g., charged before bed, sat unplugged during sleep, heavy use today (gps for 30+ min, browsing, texts) and 71% capacity as of now.

That's meant so far no identical battery with longer battery life (i.e. last 1 whole day for moderate to heavy use)? sigh...

Stick to genuine HTC batteries. Most of the Ebay fakes are far lower quality and often are mislabeled (especially if it claims higher capacity in the same form factor).
Your phone should last at least 24 hours on one charge though (unless you're using it very heavily). Try changing your habits a bit (turning off data/wifi when not using it) and also maybe try a battery calibration. If you do a battery calibration make sure you read a few guides on google and do it properly otherwise you will most likely be worse off.

Some aftermarket hi capacity battery need a special battery cover which makes it very ugly

I bought the 3500 mAh battery with fat back cover (from Ebay). Its a chinese ****s production... We know that on our IncS the antenna is placed inside of back cover. This chinese cover has some antenna as well, but the signal is much worse. For example with original cover I get like 4 full bars. With chinese ****s cover I get only 2-3 bars.
Im already having troubles with the signal in some places, but with this cover it will be even worse.. So I stay with my original HTC back cover. Dunno what to do with this 3500 battery..

why don't you buy another stock battery ?
i think stock one is gd enough.

I think that MUGEN 3600mAh is optimal high-capacity battery on the market. Its stable and reliable...

Apparently, they claim to use Lithium Polymer technology as opposed to Lithium-ion.
Wikipedia says Polymer is superior to ion but also more expensive.
Only mobile manufacturer known to supply phones with Lithium Polymer batteries is Sony Ericsson.
Seido 3500mAH battery for HTC Incredible S is on eBay for $69. It says its assembled in Taiwan? Its also not as FAT as Mugen's but still needs a back door, which is included. They also have a website.
Mugen might have a new, superior competitor.

[Q] 2430mAh Battery

Has anyone tried this GOLD 2430MAH BUSINESS BATTERY FOR DELL STREAK MINI 5 battery here? (Just check it out on ebay, i can't link it because i'm a new user)
Wondering if its worth getting it or if I should just get a cheaper pack with a charger and 3x 1800mAh batteries? Mainly looking for an extra battery to take with me on long car trips so I can use the phone more like a tablet, but I wouldn't hate having a longer lasting battery for daily use either and then using the stock battery as my extra.

this looks interesting..one thing good about it , is that is the same size as the original dell battery.

I think its a fake capacity, the largest capacity that fits as standard size offered by a decent battery manufacturer, Mugen Power is 1800mah, and if you read the threads here, there is a 2400mah extended battery that has to use a custom battery cover because the battery is twice the depth of the standard battery.
So, i think you will find its not really a 2430mah battery, but a 1800mah battery at best.

if it seems too good to be true...
The best bet is to get one of those external battery packs with 3000-6000mah and a spare cable.
Also be agressive in your control of screen brightness and data use

If you read the feedbacks of that seller on eBay. There are heaps of negative feedbacks from buyers calling him a CON.

I bought off amazon since it had to be shipped to India... think there was only 1 seller in Amazon and he seems genuine.

There's a point with batteries where to make them any more powerful you must make them bigger. If fitting 2430ma into an 1800ma package was possible Mugen would have done it, so yes the rating is a lie.

Has anyone tried this GOLD 2430MAH BUSINESS BATTERY FOR DELL STREAK MINI 5 battery here? (Just check it out on ebay, i can't link it because i'm a new user)
Wondering if its worth getting it or if I should just get a cheaper pack with a charger and 3x 1800mAh batteries? Mainly looking for an extra battery to take with me on long car trips so I can use the phone more like a tablet, but I wouldn't hate having a longer lasting battery for daily use either and then using the stock battery as my extra.

Sorry. Thought you asked for the regular 2400mah.

hi, i bought this battery 2 mounth ago and my phone authonomy is double now. so dont coment if you dodnt try!

Do dell sell them?

Probably a con, but what the heck… I just purchased it. If it’s not 'as stated', I’ll report the bugger.

could keep us posted about this, i looked at the seller's feedback and seems it is fake but wondering if that is true.

The Americans have a saying "You can't put a quart in a pint pot" and that applies to battery power as well. Don't waste your money.

Irritatingly, battery capacity is only shown on the battery itself and not in the device’s battery info. So, is it really 2430mah? Don’t know. But there IS a difference. The 1530mah stock battery ran out of juice alarmingly quickly – like falling off a cliff - when at 30-40%, yet ‘Business Battery’ allows heavy use (downloads, browsing, video… etc) right down to single digits. So now I can use Streak much more (I’d say several hours more of constant use) when battery level is below 50% without worrying if it’s going to suddenly die on me. No gain between 100-50%, though.
I was prepared to slag this off, but from my experience it’s genuinely longer-lasting, especially at low battery levels. How long the battery itself will last only time will tell.
I’m not prepared to test it against Mugen’s 1800mah and spend near 30 quid (plus £18 p&p) in the process.

I've read elsewhere that the cheap Chinese batteries often don't report the available power in as many steps as a 'proper' one does, so they appear to fall slower.
I don't know how old your Dell battery is but it might not be as good as it used to be when new.

Yep, I had to replace the Dell battery (after about 10 months use) because over the past week it became completely unstable – dropping to 70% after 30min use, suddenly back up to 95%, and plummeting from then on. But the stock battery right from the start was always weakest when two-thirds empty, and it drained juice even on standby. Last night it was 100% or ‘fully charged’ for over 3 hours (mostly on standby and some light doc editing)… that had never happened before.
The thing is actually stamped ‘made in Japan’… aren’t Japanese products supposed to be expensive? Looks suspect, but whatever. If it becomes unstable after a month or two then sure, I’ll invest in a nice new Mugen or Dell replacement. But as of now I’m fairly content with a £13 Ecell batt.

Got one of these last week, & have put it through a few recharge cycles etc, unfortunately, it's no better than the stock battery
Oh well, it was worth a try..

As with all cheap batteries it has a short life - no more than 2 or 3 months before it starts to rapidly drain. As a temporary and inexpensive solution it's fine, but don’t expect long-lasting quality.
