my backup battery is completely dead, how do i change it?

ok so i just bought a ppc 6600 second hand and its great except the backup battery doesnt show up at all under power and i get that "backup battery os low" msg and icon each time i soft reset. i was wondering if maybe it needed replacing or something. Right now it does not even show up AT ALL when I click the er menu. It only lists he main LiOn battery. Anyone know where I can butty the battery and how to replace it if it needs replacing. I actually get a "Backup battery is very low" message each time I soft reset so is there some way to maybe charge it?
you could test the back up battery by taking the main battery out for 20 mins then seeing if all you info is still there. but be prepared to lose your data so back it up.
Im not sure how long the back up battery should last for but 20 mins should give you a good idea. Regards to replacing the battery I have no idea sorry
I've got the same problem, low battery message each soft-reset.
No indicator in the enery program and if change SIM i lose every data.
I give it back to assistance....I can't see other way.
I got this, and this is what I did, but I don't recommend it in case it's a bit iffy.
I took off the main battery and stuck it in the cradle (the device) and it gave a red LED. This kind of worried me, so after 15 mins I took it out, replaced the main battery and over a four hour period, the backup charged.
Hope it helps,
Joe

PLEASEEEEEEE HELP T-MOBILE MDA III (QTEK 9090)

Hi Guys,
I put my T-Mobile MDA III (same as qtek 9090) on a cradle and after 10 minutes the screen turned off and the red light appeared on a top right corner. Now the device couldn't be turned on again. It looks like a completely dead device. Could you please help me what to do?
Is that a software failure or some other problem?
Please please please give me a hint. Is there any schematics that will help me in repairing the device? What is a cause for that failure?
Thanks in advance,
...MpegTv....
try to hard reset by pressing power and soft reset button
I've tried with hard reset and also with placing the device into bootloader menu with camera+record+power+reset and still nothing happened.
It is completely dead !!!
we have had this problem a few times with our blue angels at work, bad connection with the cradle seems to suck your batterie dead, we swapped batteries and pda works again everytime, This is the problem we get monthly that leads to dead looking pda's, exept that a batterie swap allways works,
ps
the batterie we swap with works too its just been drained.
Hi guys,
I discovered the cause. Something's wrong with my battery. After few minutes on a cradle the device turned ON and then reported BackUp battery VERY LOW, please recharge or replace.
What is a backup battery? Is that a main battery foor some other battery inside of device? How can I replace that backup battery.
When the device is on a cradle the backup battery is on 25% and the main battery is 0%.
What do i have to do beside charging?

Blue Angel Not Powering Up

Hi,
I just changed the screen, that is identical as the original one, for my blue angel, that was down for a couple of months without charging. Now when I try to charge the device it is showing me a red light on the charging led and not orange as it used to and as a result it is not powering up.
Do you have any idea what might be wrong?
Regards,
Michal
Battery is gone.. replace it.
Hello again!
I have a question regarding powering as well...
Can I power the battery without a running system?
anyone knows?
cheers,
krztf
well youcan charge the battery only in cradle's battery holder
elaborate pls
hi xplode!
i am not sure if i have understood you correctly, maybe may question wasn't that clear as well.... sorry! so just to be sure...
i wanted to know, if it is possible to charge the battery of the BA without having a running system (rom, wm) on the ba!
is this really only possible in the cradle? not with a normal synccable or charger?
edited to ask: is it possible to do THIS with the cradle? or cable? or both? is there really a diference between them?
forgive my ignorance!
krztf
It is possible to charge a battery without a running OS on your BA if you remove the battery from the body of the device and slip it correctly into the rear charging slot of the cradle (also means you can have a spare 2nd battery charged up.) If you don't have a cradle, then you're SOL, eh?
Whether your device can charge it's battery without a running OS you should try it yourself and let us know!
Still with the problem...
Hi, an update on my initial problem.
I received a replacement battery but the problem still persists.
i.e. When I place the device in the cradle it still lights up red LED.
Actually the battery is V20HR instead of V18HRT however this should not be a problem as it has identical specs except it has higher capacity.
Any ideas\suggestions what else could be wrong?
Battery Specs are as follows:
V20HR - http://www.varta-microbattery.com/en/mb_data/documents/data_sheets/DS55902.PDF
V18HRT - http://www.varta-microbattery.com/en/mb_data/documents/data_sheets/DS55802.PDF
Hi
I just had the same thing happen - not so fast with the changing the battery thing - It could be that the onboard battery is flat - leavve it in the cradle with the battery on for a long time and see what happens Thats what I did and eventually it worked - I know it makes no sense but it worked
Regards
John P
Hi,
Thanks for the reply however the problem is that I replace the on-board battery, pre charged.
I have not changed the main battery because it charges properly in the cradle.
Regards,
Michal.
Try putting the PDA with the battery on in the cradle and leave it a while - if it doesnt fix it take it out and put it back in a few times - worked for me and device is normal again
Kind regards

BA turning off if removed from cradle and not turning on again

Hello guys,
I have a problem, i haven't used my VPAIII for 6 months, and some days ago i wanted to turn it on, and it didn't react, so i decided that battery is low, i connected my device to cradle, and wait for some hours. So the problem is then device in cradle it's ok i can switch it on and it works perfectly, but if i remove it from cradle it turns off imediately and i can't turn on it again without connecting to cradle chargement, also it doesnt react to usb connection as chargment. Battery is totaly new it was bought from ebay (expanded 3400 mAH). Interesting thing that if i connect to cradle, device turns on automaticall and 1 time blinks led in red and goes booting system with no led light, after i see Windows screen it starting show the same right led in orange always, i see charging battery meter in windows but battery didnt go more then 50%, and everytime i boot on i receive Backup battery Very Low notification no matter how much i was charging my battery.
So i'm afraid maybe it's internal backup battery failure, or my main battery didn't get chargement then it says that charging. Maybe someone of You guys have any usefull advices, what can be the problem? Also if it possible maybe somebody can give me alink or image to see there this backup battery soldered on scheme.
Thanks ppl!!!

It sounds like the main battery is bad.
Is the battery you picked up new, or new as of 6 months ago? If it's new-new, it is still possible that it is bad.
Also, the charging circuit may have died. Most electronics will work and work, and when they do die, it's usually when power is applied to them (turned on, charged, etc).
The fact that it does charge up to 50% makes me think the main battery is bad. Do you still have the original battery? Try it and see what that does.

The internal battery is used only when the main battery is discharged or missing.
As for a link, hit the wiki.
http://wiki.xda-developers.com/index.php?pagename=HTC_Blueangel
Under the "Hacks & Tweaks" section, go into "Technical Stuff".
Thanks for reply, new battery i bought maybe 4-6 months ago i used it maybe 1 week, after that i turned off my device and left it for 4-6 months, so nothing should be happened to battery. I'll check device with old one, but it seems that device didn't work with original old one battery too.
Any other solutions, advices?
Thank You very much guys for help!!!!

TP2 won't boot or charge either!!

Hey guys, I got a real big problem.
I've got a Rhodium100, but it won't charge nor it'll boot.
When connected to original charger or pc the phone starts. Then I can see the HTC logo and it dies again. The battery seems to be totally dead
What I've triend so far:
1. Pulled out the battery
2. Multiple cabels for the charger
3. Soft reset
4. Hard reset (won't complete because the battery is dead)
5. Checked the on/off button (on top)
What else can I do to fix this problem? I'd like to try anything before sending the phone to HTC (did that 2 times before, but with other problems).
This is what happens: MOVIE
Thanks in advance

Buy a new battery and see if that helps. There are some cheap ones on ebay.
I just found another cable and it seems to be he's charging again. But after 5 hours of charging it's still on 40%.
When the battery-level is around 45% it goes downwards to around 38% and then to 45 again..
This is circulating..
How can this be?
You shouldn't let the battery completely die in the first place. A deep discharge of any Lithium Ion battery is not recommended because of this. If you've tried to do a hard reset and it did not complete, you may have destroyed the ROM image. If it doesn't turn back on, flash a stock ROM.
Always try to charge the device before it gets to 5% remaining battery. 10% is recommended, but 5% is the lowest the battery should ever be. Having a second battery is always a good idea. I have two of them and an external battery charger. This way, I can always have a battery able to charge without needing the device just in case something goes awry.
Make sure you do not turn the device on. Leave the battery in the device overnight on the charger without turning it on. If it still does not function after this, you might try purchasing another battery and charger.
If you have time left on your warranty, this is covered by it. Simply call your carrier or HTC and they will fix it for you. It's generally faster to go through your carrier if you have the option to do so.
Thanks for the tips. I followed them and it seems to be my phone is fully working again!
Nothing helps with TP2 reanimation

It's a dead battery. If it powers on by itself, then you'll either want to get a new battery or an external battery charger. Make sure you're charging from the wall, and not a USB port.

Yes, I do as you suggest - bought new battery and wall charger, but no result. I doubt that new battery or charger is destroyed, but anything is possible... What actually kind of problem if phone couldn't do hard reset, not upgding ROM, also switches on when battery is placed into? 100% fault (discharged) battery?

I mentioned that you may need to charge the battery externally if it is powering on when you insert the battery. You'll either need a friend's phone to charge it, or buy an external charger. With the external charger, let it sit on the charger overnight, pop it in the phone, and then try again. If using an external charger does not work, then you may want to send the device in for repairs/replacement.
