psp battery/Power Problem?

My PsP will not turn on with battery in. If i plug it into the charger it charges for a few seconds then stops charging. If i plug the charger in with the battery out it will turn on and work just fine. My PsP has done this before and i let it set off the charger for a few days and tried it and it worked. But now it wont work at all. I don’t think the battery is dead but i don’t really know or not. If you know anything about what i can do please help. If it helps its a PsP slim.
