Backup Battery did not recharge any more

Hello,
My backup battery did not recharge any more. Now, I can not even turn it on (the main battery is fully charged). In my area, there is no replacement.
So, what should I do now to make it work again?
Thanks

your post is a llittle tricky.. how did you know that the backup battery did not charge? and the main battery is full? when you can't even turn your XDA on?
have you tried to hard reset your phone? it might just be a software problem..

I had a trip for 2 days without my xda, and when I came back, I could not turn it on, I guessed that the battery is empty. So, I put it on the cradle, nothing happened. I noticed there were a socket on the cradle to put the second battery. I removed the main battery and put the main battery on the cradle. The led showed in red indicating the main battery were charging. And I put my xda on the cradle again, the red led showed too. After a while, I noticed the led changed from red to blue. It indicated that the main battery is full. I got the main battery out of the cradle. But my xda still in red. I tried for several time, nothing changed. And I put the main battery into my xda. It turned on. And there were a message saying "The backup battery is extremely low, please change or recharge as in the manual". I ran the battery application, it said that the main battery were 100% and the backup battery were 0%. The software started to install like to make a hard-reset. When it finished installing. It were soft-reset automaticely as usual. But the backlight of screen is turn off, and the picture look dummy. That ware exactly the time I can not turn my xda on anymore.
Now, there is something so strange with my xda. When I put it on the cradle without the main battery, the led lights in red in about 20 minutes and then turn off automaticly. But when I put it with the main battery, nothing happen.
I did try for hundred of times, but nothing changed. I guess that my xda is dead.
So sad.....

Maybe your XDA has a problem in its charge pins.
You should let it checked by someone.
I had the same problem as you before, but I exchanged that XDA with the new one :roll:

did you actually hard reset your phone yet? something like this happened to me two nights ago.. my phone went low on batt so i charged it and it was ok then so i turned it off so that it could charge better.. when i came back to check, i cant turn it on anymore so i disconnected it from the charger.. i took off the battery and placed it back.. but my phone didnt respond anyway.. no lights no nothing! my last resort was to HARD RESET my phone.. by placing back the battery and holding the power button while i press the reset button with the stylus.. and voila it's up again..

thanks for everyone, I did find out the problem, that is the backup battery,
I openned my xda and remove the backup battery, It works just like before. I also experience that If the backup battery is dead then we must remove or change the new one then the phone will work. It will not boot or charge with the dead one inside.

Why take out the battery and charge it separately ?
Just put the battery back to xdaII and place the xdaII in the cradle and charge it together. :roll:

im very sorry for my late reply.. if only you recieved it earlier you didnt have to open your XDA and void your warranty.. but it's good that it's ok now!

same here
i have exactly the same problem with my backup battery...i just got my xda 2i today and I tried to charge it up the main battery quickly went up to 100% but the backup battery has stuck into 75% and after a while the orange light become green as if it has charged. It takes either a soft reset or I need to disconnect (either from cable or cradle) and connect again in order to become orange and probably to start charging again...
what's wrong with the damn thing?

Leave it plugged in overnight then check status.

seems a bit strange to me , the backup battery should be at 100% and main battery should demisih .
once my main battery goes to 10% or under it refuses to do most things and only stores memory untill you recharge it so .........
i'd remove the battery then replace it, if that fails do a hard reset , and if that still fails , take it back to the shop as it should be 100 %

thanx for the replies , i left over night like cruisin-thru sugested and both read 100% now , guess i wasnt sure they where charging due to fact no orange amber light at top
ok after spending all night and morn reading this forum , am i right in thinking this device cant be unlocked without paying some company , and windows mobile 5 wont go on it yet ?
cheers for your help of to play with my new gadget .. bit of a upgrade from my n-gage qd and ipaq 3870

Have you tried another battery?
Have a read on my sig link, you may find something to help you
Good luck,

Look at the screen carefully under a bright light when it's charging. Do you see anything like Serial/USB? The backlight won't work so it will be faint. If there's nothing, it's a hardware problem. Starting with a new battery would be the most logical first step.

please help
how about the charges indicator, is it blink or stay on orange while u charges your universal? if the charges indicator blink meaning your battery cant be use anymore..try a new battery. it was happened to my universal
