The backup battery will drain in about 2 hours. Even after replacing with new battery, results are the same. Why is it draining before the main battery? The only way I can use this unit is to leave it hooked up to the charger at all times which does not make it mobile. The backup battery should last a long time.

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
Yes the battery can be replaced but this will require you to dissasemble the pda. The problem you face is a clear sign that this battery has failed. There has always been a problem with hp's battery measurement algorithm regarding that secondary backup battery. Altrough it is empty or even if you remove it, the program will still display a full bar. In order to change this battery you will need to remove the screws from the back of your unit. The casing will come off pretty easy. The back-up cell is a small coin like battery most probably wrapped in a green plastic shel. you should find a similar battery and connect the pins from the old one to the new. The battery size is not critical as long as you can make it to fit in the space inside. Try, however, not to use a very small battery because it will drain much faster then larger ones. Carefull when observing polarity.

You can get a replacement backup battery right here
Essentially like you said you've totally drained the backup battery, and it now has to be replaced. The repair involved no soldering, so it's not terrible difficult, but you do have to completely disassemble the unit to replace the internal backup battery. You'll need a good set of screw drivers and torx bits to take it apart fully.
Also pdasmart has a repair service they offer. For $25 they will repair the pda for you. For an extra $5 and a couple extra days shipping time that would be hands down your best bet if you aren't technically skilled in electronics hardware.
I hope this has explained your question in detail. If I've helped you please don't forget to rate me.
It's the inside battery. The backup battery has been depleted. So you need to replace it. It can be charged, Only replaced. Now I prefer you to make a hardware reset. If you still have that message. then the battery is the problem.
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.
-are all pda's this way?
All PocketPCs are this way. I don't own a P**m so I can't speak to them.
-When the main battery depletes to the point where the unit shuts off how long do you have before data is lost?
Until the backup battery dies.
-Is the backup battery just used when changing main batteries or does it take over when the main battery goes dead? If so how long do you have before it is dead?
I've never had it happen, so I cannot say how long, but if you continue to try to use the PDA on the backup battery it won't be long (minutes) if it even lets you do that. The backup is there to bridge over battery changes and to act as a safety net if you run the main batteries totally flat.
-does the backup battery recharge or does it have to be replaced?
-with a fully charged unit how long can it be left off before data is lost?
Depends on the machine. Most of us leave the thing in the charger overnight every night, so this issue doesn't come up. You could try an experiment for 1, 2, 3 days, looking each day at the battery remaining and work up an estimate. I would expect maybe a week or more. Remember, even "off" the machine is still drawing power to maintain the RAM memory.
