Note: Continuous playback time was tested after playback, with the hold switch locked and the LCD put to sleep, and no further operation. This was done to confirm whether this is an average value for the performance of the purchased battery group, eliminating artificial operation. This is not based on actual use. In reality, the playback time will be considerably shorter due to power consumption by the LCD each time operations such as operation, song changes, and volume control are performed. In that case, it seems that the playback time will be longer if the LCD brightness is set to minimum. Note: All units are initialized with iTunes, after song loading, operation is confirmed, and only normal units are finally initialized and shipped. This is a listing for a used, working unit only. Battery replaced with a new one (2025/12/19) LCD has not been replaced. Displays normally. The exterior is in good condition. There may be some minor scratches.
