Sony mz-r91 minidisc recorder BLUE - only works with battery pack or charger

Sony Minidisc recorder which plays and records, but with some issues. The gumstick battery compartment does not power on the device, multiple ways tested. It powers on fine with a battery pack or a 3V charger plugged in, as seen in pictures. The physical condition is ok, but it has some scratches on it. The charger is the smallest plug possible, you might already have one that connects to something else you own. Beside the internal battery failure it is important to note that the screen is temperamental and does not always display!These defects are why it is so cheap for a functioning md recorder. Let me know if you have any questions, but I do not have any extra battery packs and I use a universal charger for testing these.
