I've been looking around the net for a replacement battery for an XDA1 and I've found somewhere that has them at a reasonable price, but the site states the battery is suitable for an XDA1 and XDA2.. I thought the battery was different in the XDA2 ?? :?
The model shown on the site is a PH17B
Cheers

Hi,
have anyone expericene in building an addition battery pack für the mda-II?
With wlan i have only 90min to work on the device.
Maybe we can user an akku from camcorder or mobile phones? (Very small and powerfull)
The orginal mda-II akku has 1200mAh and the powerconnector loads the device with 5V max. 2A.
Any ideas?

Hi!
What do you think of 5-6 AA/Mignon 2000 mAh rechargeable batteries combined with a low drop voltage regulator?
Maybe it fits in a old tape cassette cover?! (I don't have one available for testing.)
Jens
Great idea.. AA/Mignon in a old cassette cover.
I will test later on how much Ampere really is needed to load the pda and how much is need when the build in batterys are full. I think this is different.
My goal is to have enough power to use the wlan more than 5 hours if possible

O2 were talking about an add-on sleeve that includes a CF slot and extra battery. Available shortly apparently.
Steve
Checking the O2 website see http://www.my-xda.com/backpack.html
I see battery extenders on ebay, just a small box with alkaline or rechargeable batteries inside, have you tried those, very cheap too.
Backpack
Exclusively for Xda II, the backpack is a powerful expansion unit. The jacket provides a compact flash card slot, a 600mah additional battery and VGA/TV out, allowing you to connect your xda to a projector, monitor or even a television (PAL/NTSC).
This Compact Flash slot supports Wireless LAN, GPS, Bar Code readers as well as normal CF storage cards (including the IBM Microdrive®)

You need 5 hours of working batteries:
1200 mAh / 90 min => 800 mA / h
You need another 3 1/2 hour => 2800 mAh if current coming through the power connector is about worth the same as from internal battery.
A small plastic box with mignons seems to me more flexible. Do you really need 5 hour ?!
What's about a 6V sealed Lead-acid (right name :? ) battery with voltage regulator?
Put the battery in your backpack connected to your XDA by a wire and you can walk through your city. :wink:
Jens
tanks all for your answeres!!!
@sweeney
I have read about the backpack and it is very interessting with the CF-Slot but i heard a price of more than 200eu... thats to much for me. And the additional battery is with 600mah to small.
regards
AleX
@alex
This one I have used with XDA II
The price is OK!.

O2 were talking about a price of about £90 (about 130eu), then I was thinking in terms of a low power CF 802.11 card (say the socket unit (http://www.socketcom.com/product/WL6000-320.asp) which with a maximum requirement of 280mA in transmit mode and it's fancy power management drawing from the backpack's own power cell should be good for over 5 hours.
You could of course lug around a bunch of spair lithium cells or a battery pack and cable, kind of defeats the objective though.
Steve
Dear,
Does anyone know the answer?
Many THANKS!!!!
Yes they do, i use a couple of old XDA2 batteries, on mine with no problems, The only differance they last a little less due to the fact the xda2i battery is 1300ma and the XDA2 is 1200mha. On the same the XDA2i battery of corse works on the XDA2. Basically here with have a XDA2 and a 2i with chargers and batteries everywhere and both of us just use the nearest battery when needed
John
thanks for yr reply

I'm currently charging my HTC Touch Diamond with the included 1200mAh batteries. It's supplying between 400-540 mAh.
It may not be a neat solution. You can also use higher capacity batteries (so I've read). You can also charge it from any usb source. It's also general purpose as you get a number of adapters.
In an emergency, you can use alkaline batteries too.
Whoops sorry, didn't think that page would come up. This link should work.
the link just asks for my postal code, what am i supposed to be looking at?
As a external powersupply, it says that the capacity is 12000 MAh so enough for 12 charges, or do I make a mistake somewhere?
It seems that a miniUSB connection is suplied whit it so I shouldn't now why it wouldn't do the job and the size is (for me) acceptable with almost 3x3x0,5 inch, I mean for tracking at locations whitout electricity it could keep your GPS going.

I am sorry forget the link
Willem
Tried what? No link? Product name? Anything?
USB Charging
Not sure about how many times it would charge your diamond...but it looks like it has a Female USB connector so any USB cable could be plugged into it to charge ANY device...if your device allows USB charging that is.
Best regards
Wasim
12,000Mah!?!
Doubt it, must have been some serious squashing to get that much juice in there!
My laptop battery is twice the size of that and has 5100Mah capacity. Would be great to be able to charge it from that thing!
Ill just ordered
I just ordered the battery and as soon as it arrives I will write a review of it.
Willem
I don't think it'll work. There were some user reviews on similar charger saying it won't charge their ppc's through USB.

your laptop battery is also higher voltage, probably 12V.
think of the AA-size NiMh cells, the best ones are 1.2V 2800mAh.. two of those aren't close to the size of a laptop battery and yet they have higher mAh.
but you're right, 12000 mAh in that thing is utterly impossible
edit; anyone tried this?
http://www.instructables.com/id/Portable-USB-Charger-Version-2.0/
edit again; this seems more like a real product, but it's larger than the actual diamond is. not too convenient.
http://www.proporta.com/F02/PPF02P05.php?t_id=4125&t_mode=des
late edit; if a computer usb connection is too weak to charge the diamond, shouldn't it be possible to solder a cable that connects the diamond to two usb ports simultaneously?

I have one of those crummy double A chargers from energiser i got from a friend and using the mini usb included with it, the phone does indeed charge but only when its off. When its on the power its using makes the battery pack redundant, but thats for my crappy charger. I think this should work, and if not it would work for another phone or device.

I made a small calculation my 2000MAh is in size 40X35X10mm =14000mm3
The size of the 12000MAh is 74,93X74,93X14,986mm=84138,9704314
84138,9704314/14000=6,0099264593857142857142857142857
6,0099264593857142857142857142857 X 2000MAH (which is the size of my battery)=12019,85291877142857142857142857
Acoording this caluculation it should be physical possible I just don't now how much cell it has and neather or by just doubling the size you can double the capacity aswell.

That's true for another Li-Io-charger which I bought from DealExtreme. From what I can see, they don't check their inventory very thoroughly for function and quality. Most of the stuff is just fine, but there is also some junk - and my Li-Io-charger was among it.
Since they advertise it only for the PSP, I can imagine that it will not offer the high current to charge a working Touch Diamond.
Have fun!

Do you now howmuch is the power use off a PSP?
I do agree with you that not everything is made off gold what they sell at DealExtreme, I also bought already some useless stuff from them but this item should be a verry big mistake from them cause there are rumors at there site about this item, I even doubt about it aswell and thats why I cancelled the order but after I made the calculation I am in doubt again.
I travell a lot and one off the country's which I visit a lot is Brasil and for such a country whit the infrastructure availleble (or just NOT availleble)
If you make a long bus journey or plaintrip (Brasil is at least 12 hours where in you have nothing to do) or even in the bush or just tracking such a item could be ideal.
Willem
After a email with my doubts Deal extreme send me the folowing message, in a previous message Itould them about the doubts and asked them to check or the ordered battery is realy 12000 mAh, they have checek it with the suplyer which confirmed the capacity of the battery, as soon it arives I will post a review of it, which maid take a few days cause I want to test how many times I can charge my phone with both a 2000mAh and the original 900mAh battery.
Dear Willem ,
Thank you for your reply.
Item 19086 was shipped on 12/31/2008 after checking. The supplier informed that it is 12000mAh, we will keep the ticket open, please feel free to send the news once you got it?
Thanks a lot.
________________________________________
Received the battery
Received today the battery but the Mini USB doesn't fit at my Diamond the output is 5V 700mA anyone now or this is enough to use and charge my Diamond at the same time cause if this is possible I will try to make a custom cable.
Someone can tell me aswell which contacts are used to charge a phone on mini USB, as you can see it seems the contacts are about the same there is just a diference at the outside off the connector, the main outside connector is a standard plug but I don't now or there are connectors at the market to make from the standard connection a mini USB
The connector fits at my dock and is able to charge my phone so in case of emergency I can charge the extra battery that way
Here some pictures
http://84.104.255.96/connector/index.html
Well I tested the battery and the outcome is disapointing, could charge my 2000mAh battery once complete so I gues all the critics about it where right, I have contacted Deal Extreem but untill now no answer.
Willem
I find that iphone have an 2000mAh Rechargeable External Battery Pack that atached like a silicone case mix with car docking in Dealextreme see the link:
http://www.dealextreme.com/p/2000ma...ack-for-all-ipod-iphone-2g-3g-3gs-black-32202
it look like it can be a good Accessorie for the desire but I can't find one like this for the Desire
since you are from israel.... you have got some kind of Energizer power pack it cost around 100 nis but it is not a good looking one but it is use-full
HI
Don't Know if it's still relevant but I bought PortaPow external battery charger, with 3000mah capacity. They also have cases that charge the phone, even with solar power - I loved them a lot.
A bit more expensive, but worth it in my opinion.

Dan
looks usefull !
thanx for the link
I just ordered mine, it should recharge my Desire 3 times.
http://www.proporta.com/F02/PPF02P05.php?t_id=5330&t_mode=des
One thing you guys might be overlooking is that the sated capacity for most of these power packs is at the batteries 3.7v. The unit then has to turn the 3.7v to 5.5v which will mean the actually mah you will get out of the device to your phone will be lower.
Still useful though if your battery dies!
Phil
Im in the process of making something simular, it wont be pretty but it will do the job.
I have ordered a 4x "C" Cell battery holder, that I will wire to a USB cable.
I have a few C Cell 3000mAh rechargables @1.2v each.
1.2x4=4.8V. I figure, this should be close enough to provide power into the desire.
It wont be pretty, but it should charge the battery of the phone a few times when im out for a few days
Total cost will be way less than the cost of the ones you buy.
Thanks for the links. Still deciding which one to get. Anyone have any experiences with the above?
