Things You'll Need
Instructions
Make sure your PSP is turned off by pressing a button on the PSP. If the screen lights up, your PSP is still on. Slide the power button upwards to turn the PSP off.
Connect your A/C adapter to the power insert on your PSP. Remove your normal PSP battery from the battery housing on the back side of the PSP. Turn on your PSP and wait as it boots up.
Insert your Pandora battery into your PSP. The Pandora program will not start because the PSP has already booted up.
Keep your Pandora battery in your PSP, with the A/C adapter inserted, for an hour or so. This will charge the Pandora battery fully. If you do not use the Pandora a lot, its one charge can last a few weeks.
