“Is the Dynex Universal laptop Charger Model DX-PWLC591 compatable with a Dynex Nickel Metal Hydride Battery Model DX-N/101 ? This is a 9V/4300 mAh battery used to plug into a portable DVD player. The battery tip does go into the DVD player but I need either a transformer to convert AC to DC and plug into the battery. This has been discontinued and I do not need to buy a new battery.”
