I have one sansa sandisk mp3 player. I have not used the mp3 player or even charged it now for few months. And now the batteries are dead. I also lost the charger of this player. Now I want help from you guys out there. Can someone suggest me where I can buy batteries for mp3 player in California. In addition, I would also appreciate if someone can give me some online links from where I can buy these batteries. Please revert to me at the earliest.
