I believe the black type is rare. I did a simple operational check, and the battery worked for 2-3 hours during the test, but I don't know about longer durations. There is no swelling. I confirmed the operation of both DVD and SD. Since it's an old item, I cannot guarantee future operation. The main unit only, no accessories are included. There is dust and scratches, so please refrain from purchasing if you are concerned. No claims, no returns, please.
