I found at the local dump a COBY TF-DVD7005 Multimedia DVD/MP3 Player.
I need advice as to how to charge it, or where to buy a battery for the DVD Player.

This should be in Technology I think.
This forum is for Menewsha questions only I believe.

As for your problem, I don't know, but I wanted to give you a heads up.

I always say: whenever in doubt, google it.

Well, considering we dont really have a tech forum for now. A post concerning these types of things would go in Computers & Video games. I will move it over to there for you for right now. =)
