The only devices I have used that allowed for easy user replacement of the backup battery were the old HP Jornadas. That was something I really liked about my 568 - it used a button backup battery that was mounted in a slide-out tray. It sounds as though the backup power source on your iPAQ has reached the end of its life and AFAIK, it is mounted on the motherboard, so replacing it would be a fairly involved process. |
