Be sure to add me to your favorites list Yamaha Battery Cover for Many Yamaha Portable Keyboards (D Battery Sized), for many PSR / DJX / DGX Models and More, Black Version. This is a battery cover for a Yamaha portable keyboard. It will fit perfectly over the battery compartment of most of those models that accept "D" sized batteries. Let me know your model # and I can help you decide if this one will fit if you're not sure. Many PSR / Portatones, and a few other models, such as the DJX models and a few DGX models, will take it. It is a little under 3 and 3/4" inches long. It is in good condition, not warped or cracked, and has it's latches intact. There are marks on it but no damage, and it will complete your Yamaha keyboard, with no need for tape. The sponge that was once inside is gone, which is not unusual, but it is not nessesary for the battery cover door to function. This one is black in color, but will work on those keyboards where the previous cover was blue, green or white, etc. So replace your lost or broken cover with this one! Thanks for looking!
