My mum has a jukebox 20, it does not have the easily accessible batteries like the machine my son has. It seems to be not charging properly, she's charging it over night and it's still only seeming to play one C.D. and then it's flat. I'm assuming it's the battery but haven't a clue where to get one or how to put it in??? Have e mailed Archos and they have been no use at all. I bought it from someone so there's no warranty or anything. Can anyone help??
