Panasonic is really betting on one aspect of their MP3 players - the battery life. With that being said, the upcoming SV-SD870N is capable of playing music continuously for 100 hours.

In other words, if you listen to music 24 hours per day, this player will last 4 days and 4 hours. A good record, don’t you think?

On top of the usual support for MP3 files, the SV-SD870N can playback AAC files, and as strange as it might sound, there is no internal memory - you can only use SD/SDHC memory cards. One SD card of 2GB is already included in the package.

The new Panasonic MP3 player will hit the shelves next month, April 18th.
