My PSP doesnt connect to the battery! yet it does... strange problem.

a while back i was messing around with pandora to downgrade a PSP. after downgrading and normalizing my battery i noticed that my PSP doesnt connect to the battery.(i have used pandora mutliple times with this battery)

i can power on only when my PSP is hooked up to the AC charger. when my battery is inserted the LED turns orange(charging) but it never charges a bit.
cuz as soon as i disconnect the charger my PSP shutsdown.

after a while i wanted to use my PSP again so i ordered a new battery (i thought the problem was the battery)
also with the new one i am not able to use my PSP

what should/can i do?

thanx in advanced

Did you cut the battery, or did you just use the Easy Pandora Installer?
If cutting is the case, you might have touched something that connects the batt to the PSP. It doesn't need to be cut to have the batt not work.
OR it's just too old.
EDIT : Nah, you did something with your psp that can't read batteries. 2 options:
1: Buy a new PSP.
2: Use the PSP with the charger, but that's annoying.

i agree with edjersy

i ordered a new battery which refused to work too...

i thought everything was lost and that i had to agree with edjersey

but i tried the battery from an other (working) psp and guess what is worked:)

so it seems that they delivered a faulty battery
