the forum here is full with problems of people who did get a cheap chinese battery from ebay or somewhere else, that is not recognized by their htc hd2 and is discharging at the rate of the shipped original small battery.
also the forum is full with "solutions" that are NOT WORKING that WILL NEVER WORK.
this is the reason for this thread to give the people the one and only answer to fix their problem!
first of all, be sure to have the newest firmware to have the extended battery driver.
but this will only solve charging problems if you got one of the first shipped firmwares.
after that get the ORIGINAL EXTENDED BATTERY. also the 2300mah battery from the company "leicke" is working for me. (looks identical to the original extended battery, maybe its the same)
this batteries will be recognized correctly and will discharge in the right speed!
--- got a chinese "noname" battery? ---
your battery is crap like most other extended batterys for hd2. get another one, but continue reading the rest of this thread before!
i had a cheap 2400mah chinese battery before and had the same problem.
the thing is, that these chinese batteries are faking, they are normal ones because the driver of the hd2 origininally didnt support bigger batterys in the first roms.
the chinese batterys are out of date (they only added a kickstandcover) and also the capacity is mostly a giant fake!
i disassembled my chinese cameron sino battery and here is the result: its made of 2 small batteries pakaged in one frame and controlled with one chip that is sending fakedata to the phone, also the temperature is recognized wrong because it doesn't really have a sensor! it always shows 25,X°C all the time. like i said: totally faked data
tip but not a solution: if you discharge your chinese battery to 0%, remove it and put it back into the device, you should have 50% again, but thats no calibration because a calibration of this batteries is not possible!
my "leicke" battery did cost 21 euro incl shipping and is working correctly, also the high quality cover with metal-kickstand is fitting perfectly, not like the chinese ones that never fits!
dont try to fix the problem with hints and tricks or calibrations, it will NOT AND NEVER work with the cheap crappy chinese batteries! i already tested it!
i hope this thread is helping the most people with their cheap-battery-problems.
thanks for reading
Cheers for the info,,,, really was dissapointed with the cheapo one i got the other day..... Could you provide a link for the leicke battery?
~Many thanks in advance....

here is the link of my battery: http://www.amazon.de/LEICKE®-Akku-7VDC-2300mAh-Akkufachdeckel/dp/B0043DOCFE
working 100%
i paid 20.99,- euro 3 weeks ago included shipping inside of germany. current price is 15,- euro without shipping
thanks very much! on order now...
How long does the Leicke battery last by you ?? By me not too long , just a littel more than the original -.-
for me it lasts with wlan on and permanent internet using ca 10-12 hours (and still is not empty). in standby-mode many days and maybe weeks with windows mobile. (under 5-10% draining a day with phone on)
it lasts nearly the double time of the original battery. i can tell you, that the 2300mah are the real capacity and how long your battery lasts depends on your systemsettings, phoneusage etc.
i use battclock to control the current powerdraining. with wlan on it is ca 140-300mah but mostly a little bit under 200mah. so you can calculate yourself how long the battery lasts until it is empty
I'm using the licked battery too and can confirm that it works correctly with the hd2. With current android builds the battery last for 3 days with moderate use. If you can live with the bulky shape, the leicke is definitely a great alternative to the official HTC extended battery. Cover and stand are also quite ok, aluminium cover would be nicer but can surely not be expected at such a low price.

I use the cheap China batterry 2400hr
I bought off ebay for $14.00 US shipped and it works perfectly. The back cover fits like it was made for it. Snaps on cleanly and has never come off or stick up on the edges. The battery charges with Android and WinnMo to 100% and lasts for days. Most of your charging problems may be your rom or radio version. There are probably multiple makers in China so some may be better than others. My Cheap China works works okydoky!
can you share the companyname and capacity of your battery? many people are interested in that
Here is the current link.
It has gone up a little bit. Just bid on it to get the cheaper price. There are several in his store. I got mine several months ago. Just buy a cheap silicone case and cut a hole for the cover to stick through on the back. Works good and looks fine. Only HD2 snobs will know any difference!

Just bought the Leicke too.
Unfortunately it does not charge at all in WinMO
I use an NRG rom.
It seemed to work in Android but it went really fast downhill at 50% at 7% or so it was at 3.9 Volts which is rather high to be at that %.
maybe your rom don't support extended batterys. try another one like the oem rom from htc and test it.
the first roms didn't charge real extended batterys.
and you need the right android kernel for extended batterys because many kernels are buggy,
i use the kernel of froyo sense 2.4 and its working perfectly
Which WinMo rom are you using Schildzilla?
i am using a german rom called "EPS V5" - it is only a little tweaked oem rom with the newest drivers
thanx a lot.. i'm gonna update the kernel
Its nothing to do with the battery , its the android os and he kernel which is main cause of the battery not getting detected where the manufacturers are putting in the code which only detects the stock battery and thus your extended battery reports and drains like the normal battery.
I have a mugen 4800 for my dell streak and because of dell's coding my battery is not getting detected on froyo and on gingerbread, however it is getting detected properly on android 1.5 and 1.6 so its nothing to do with the battery. I agree to your point regarding the kernels having the extended battery support and that is the main cause for this reporting error.
Thanks! Great info mate
Leicke Extended battery only charges when switched off
I've just bought the extended Leicke battery (from Amazon @ £15.)
When plugged into either my laptop or to the mains adapter I get orange and green alternating blinking lights and it doesn't charge. When the phone is off, the light is constant orange and charges.
I have the standard WWE ROM 3.14.405.2 and have just reapplied the same ROM in case I've done something to cause the problem.
This FAQ seems to confirm that the battery won't charge when the HD2 is on as a result of something that HTC have put into the Kernel to try and make sure that we only buy HTC branded batteries. It seems that I will need to go to a custom version, although I may just leave it off over night when charging.
Thanks.
Hi guys,
Got an HTC extended battery. Not recognized by my hd2 running Pdaimatejam WP7 ROM Ver-7.1. I have read though many threads on XDA, but no solution !
After charging in magldr mode for 10 hrs it shows only 55 %. And the battery tool by HTC only shows capacity as 1230 , while the actual capacity is 2300.
Can any one guide me to a wp7 rom which will recognize the extended battery.

I would also need some help, the "stock" MIUI ROM doesn´t recognize the Leicke extended Battery...
Could someone please help me with all this Kernel stuff etc. I´ve read a lot but I don´t know what special Kernel is compatible with what ROM...
EDIT: Is it an alternative to just buy an externel battery dock so that you could just switch the battery if it´s empty?
http://shop.ebay.com/ec.force/m.htm...dkw=HD7&_osacat=0&_trksid=p3911.c0.m270.l1313
I couldn't resist. I ordered it. What a great deal! Should get it in a month knowing it's probably coming by container ship.
Has anyone else purchased similar 1500mAh batteries from China and experienced better battery life?
I never buy non-OEM batteries from eBay, because the batteries can brake and destroy your phone, but they can be good quality.

I've owned several non-OEM batteries for the HTC Touch Pro for years and they are still perfectly fine and hold just as long of a charge.
Maybe there's a battery program for WP7 that can test these batteries properly like there was with WM.

Also I bought an extended 3500 off eBay don't bother... I hae developer unlocked HTC hd7 and the touchexperience and desktop program show the extended battery as same size as stock. It also doesn't seem to last any longer than the 1500's. I'm actually happier with the 1500's

I've seen there are a lot of business/gold batteries on ebay, with 2430mAH...anyone has tested one of this? there are real benefit with this kind of battery??
Thanks.
i have it . works 1d9h and orginal bat works 26h not so better i expeckt better dan dit
I was looking around and saw those too. It would seem that the Mugen Power batteries still provide better life generally.
The claimed capacity is never the real capacity
Mugen is the best battery on the market, i think

Total fake and ripoff!! ...so dont be wasting your money...
Here, read "all about it" from my experience in another paralel forae - "conclusion" after testing on post #21: http://forum.xda-developers.com/showthread.php?p=20373274#post20373274
I only know 1800mAh battery but this one is legit.
looking for a new battery for my Legend, any suggestions?
What is the best moneyworthy alternative out there, i lost the old one, so i just need a fairly good battery, and hopefully not less good than original, but better value for the money wouldnt be bad.
I suggest mugen
I uses this battery for about 4 weeks and it works great within this time but after round about 6 weeks the battery lifetime reduces to a minimum and at the end i only was able to use my legend for about 6 hours with about 70% of standby-time. I dont know if it was a manufactoring error or this battery is just crap? Meanwhile im using the original battery again...

Definitely the Wildfire. My friend had a Wildfire imported to Canada (stupid idea) and the battery I ordered works interchangeably between the two. Though he wasn't scared of the risks because it had printed Wildfire/Legend on the back of the battery. I'd imagine the HTC battery is at the very least similar.

Wildfire is compatible but HD2 have a different format and a different kind of connector - 100% incompatible.

I have one Gold battery and it work ok, is a good value to the money.
The battery I buy in webstore Pixinf can work more that 2 days and the original one only work less than one day.
Be carefull, I think some gold batteries are made on china (not in japan) and are copy ones (fake).
Kind regards

Ive been looking for extended batteries, and found one on play.com that mentions its also HTC Wildfire S compatible, does anyone know if this is the case?
http://www.play.com/Mobiles/Mobile/...archsource=0&searchstring=hd7&urlrefer=search
If it is, can we not use other extended batteries from the HTC Wildfire S? thus giving us more mAH?
I believe they are the same battery... I had someone at work get one and return it... I switched the battery before it went back when.
I only noticed they were the same when i was putting both my phone and the other one back together, I obviously keep hold of the newer one
I can confirm they are SIMILAR. I'm not sure about the same.
I bought a 3500mAh HD7 battery for my wildfire s and found that the battery contacts were on the wrong side, so I had to 'adjust' it to work
I now get 2 days VERY heavy use or 6 days standby/5 days light use.
I would be curious to know where you bought this battery.
A lot of eBay listings for HD7 batteries also state they're for Wildfire S too...
yes they share the same battery.
Hi Just a Thought
was wondering if we could use Other batteries from the HTC range of phones for our HD7 as the newer phones have around1600 mAH batteries.
Like the HTC sensation XE HTc Rhyme.
The reason for asking is as the other higher capacity batteries available for the HD7 are so big they make your phone look ugly, so this is something I am looking into.
The only thing I was wondering though is the voltage of the batteries which might make a problem.
Any one willing to shed some light is welcome
Mugen Power - 3900mAh
If u referring to other htc phone batteries
The htc wildfire S is the only phone which shares the same battery as hd7 but it is still the same 1230 mah .
Of cos u can use any aftermarket , china or mugen batteries with hd7 so long they are compatible
