I have the Sony E-DJ2000, it's 1 of the thinnest CD player, a collector item The battery is Nh-14WM, this same battery is use on a lot of MD player as well. I bought some compatible from ebay. They are horrible, junk made in China they don't hold charges. They hold for a few days or even a few hr., then the battery strength totally disappear then there are these dealer that sells compatible, like do you take a chance w/ them, or what can you do? http://www.gnbatteries.us/servlet/the-
