I am curious if it is possible to use my Archos Jukebox 20 with the car power adaptor and remove the batteries? IF I have to have the batteries in, can I play my music without it charging? Or does it charge anytime external power is applied?
I really want to save the batteries for other needs and just run off of car power.
I didnt see anything in the FAQ's or the Rockbox manual covering this.

Thanks in advance for any advice,
