psp not detect battery issues 

I had the exact same symptoms. But I replaced it with a new battery and it was cured. I don't know if it is a voltage issue or a model number issue.

Same issue I have with this psp as well, new batteries and all , any fixes?

For those who ask how to solve this problem, This might be the power ic issue, it's a tough fix, you can reflow it or replace the ic

I replaced the old battery in my PSP because it didn't appear to fit as well as my new one did. This is how I fixed mine.
