Note: Continuous playback time was tested after playback by locking the hold switch and putting the LCD to sleep, and then leaving it untouched. This was done to eliminate human operation and confirm the average performance of the purchased battery group. This is not based on actual usage. In reality, the playback time will be considerably shorter due to power consumption by the LCD each time you operate it, change tracks, adjust the volume, etc. In such cases, it seems that the playback time will be longer if the LCD brightness is set to minimum. Note: All items are initialized in iTunes, songs are loaded, and operation is confirmed. Only those that are normal are finally initialized and shipped. This is a listing for a used, working unit only. Battery replaced with a new one (2025/11/22) LCD has not been replaced. It displays normally. The exterior has many scratches. Please take a good look at the photos before purchasing. Also, we hope that those who understand used items will purchase. Charging, PC-related operations, music playback operations, click wheel, hold switch, FM, video camera, pedometer, voice memo, and sound from the built-in speaker have been checked and are normal.

Test conditions: Fully charged (plug icon appears on the battery mark) Volume at the center position Airphones used were those that came with the iPod (90cm long) After playback, the hold switch was locked and left unattended Playback was checked occasionally until the estimated end time.
