How do I fix my PSP fat's battery?

2 psp, one stopped working and tried all 3 batteries i had and now all batteries short circuited. How do i fix

• I have 2 psp's. One is version 1.5 one is 2.0. The 1.5 has stopped working before and would not work until I charged with the charger that came with it as I was only using the 2.0. I though that was weird. Now I can not get the 1.5 to turn on. I tried the battery in the 1.5 in the 2.0 but will not hold charge. My 2.0 worked. I took that battery that worked and but in 1.5. Now that battery will also not hold a charge. I then stupidly took my double life battery and stuck in 1.5. It also shorted or whatever and battery does not work. Does anyone know how to fix the batteries (heard you can short or something and will fix) and how can I now get my 1.5 version psp fixed as will not turn on even with power adapter. Thanks!
