To unplug the PSV battery, first turn off the device and make sure it is no longer charged. Then, turn the PSV upside down and find the battery compartment door, which is usually located at the bottom of the device. Press the button next to the battery compartment door to open it. Gently pull out the battery, then completely remove it from the device. If you encounter difficulties, you can use your fingernail or a small tool to gently push the battery and remove it. Remember to check that the battery is clean and non-destructive before reinserting it, otherwise it may affect the performance of the device.
