PSP 2000 battery external charging

Can you help me my PSP 2000 can't detect any type of battery

I have the original battery but I think it died already, because it's old, when i plug the original battery it just blink orange light then green light, alternate then the orange light will be gone.

My psp only turns on when plugged in via charger, I tried using other psp batteries (brand new class a) so I plugged in the battery, it has the orange light a sign of charging but still it won't recognize by psp, the battery information says (battery external) and the other information are blank

I can use my psp/play games when plugged-in via charger no other problems except the detecting of the battery.
