I recently bought a used iPAQ. The battery drained fast, so I bought a new, high-capacity battery.
The battery charge is UNRELIABLE. I might have 80% or more battery available, go somewhere, and the iPAQ will not even turn on when I arrive-- battery at 0%.
If it is in use, it works fine from 100% battery down to 65% or so and then ALL OF A SUDDEN, is at ZERO and turns off. My "high" capacity battery lasts for 2-3 hours and then this happens, not even with WiFi or Bluetooth radios on, just playing an MP3 or something. I returned the new battery and got another one, the sales guy tested it and filled it up and it is not the battery. Plug it in and the same unreliable behavior.
