The backup battery is not user replaceable.
If you have some electronics experience you could open the device and replace it yourself but it involves cutting out the old battery and soldering in a replacement.
An easier solution is to take it to a phone repair shop and get a quote to replace the battery, probably around $ 60. They may even give you a 3 month warrantee.
You need to purchase a new removable battery for your RX
The removable batts usually only last about a year (like cell phone batteries).
Although it is showing 100% charge, the battery is not storing enough power to run the ipaq
The rx series uses 2 batteries, one is the removable one u can see/access when u remove the back cover. The other batt is a small round batt which stores the basic info for your system (so you don't lose your data when u swap out the removable battery).
This small (backup) batt is similar to the cmos battery on a laptop or pc.
You cannot easily replace this, as the unit needs to be disassembled to access this batt.
If you are tech-y (and brave), the replacement button batteries are sold on ebay for $9-12
Normally, if your removable batt is bad, you could still use your unit plugged in, and could
remove from AC power without losing data. Not the case if your replaceable batt is exhausted.
When both batteries are bad, you lose everything when u remove unit from AC power.
My workaround without having to disassemble unit:
Purchase and fully charge new removable batt (They have huge capacity ones available for like $15 - better than the original !).
Load up all your programs & settings the way you like.
Perform full backup to SD card (& also on PC via active sync - to be safe)
Now the only time you should lose your data (like hard reset) is if you allow the battery
to completely drain, in which case you can restore your backup.
If you purchase 2 removable batts, you can easily swapout without losing data if you
use the usb charge cable & leave ipaq plugged in while you change battery
The backup battery exists to protect your data when the main battery dies. It only has enough power to keep the internal memory 'alive' so you dont lose your files, settings etc.
When the backup battery dies it should be replaced as soon as possible, as the main battery will power the internal memory only while it has charge. Should the main battery die it would be like performing a hard reset.
The h5450 comes with what HP calls a backup battery. It is built
into the device and not accessible by the user. However, the backup
battery has only enough juice to power the Pocket PC for a few minutes
while you change main batteries. Don't expect it to keep your RAM data
alive if the main battery runs out.
I will attempt to answer both questions and give some insite.
1st- No, the charger does not recharge the backup battery. The battery is the same kind of battery as you would have in a watch which at this time are not rechargable, but that would be a great idea.
The way it works is that when the main battery is charged the X5 uses that as its energy source. Only when the unit is off and or the main battery is depleated does the back-up battery kick in. Hence the name (back-up battery).
As for a solution to your problem. It sounds to me like you have a problem with your primary battery. I don't believe that it has much time left or it may just be a corrosion problem. I would try clening the battery contact point on the battery as well as on the X5 with some alcohol and a q-tip. I would also check the contacts where the back-up battery is. I have worked on watches before and their batteries will sometime cause some corroding.
The back up battery should be replaced immediately upon seeing the message "Backup Battery Very Low - Your back up battery is very low or missing. Data loss may result from failure to replace the battery very soon. Consult the manufacturer's instructions for directions on replacing or charging the backup battery."
Warning: It is important to note that the back up battery in the MobilePro 900 is not rechargeable, thus, to prevent data loss, it is important to change the back up battery immediately when this message is displayed.
You might hook your charger up to your battery and check the voltage that you are getting when it is fully charged. It may be that the charger is bad.
Your voltage when fully charged with the battery on it should be a little over the rated voltage of the battery.
Just a thought. Be sure you are using the correct poweradapter/charger also.
