I think my pandora's battery went below 3V

[-_ae86_-]

  I tried to use my home made pandora's battery but apparently it looks like it drained below 3v and died.  I haven't used it since 7th grade (lol).  I tried to charge it via the PSP but it won't charge.  Is there any way to revive it?

look at the "Accual" battery, inside the plastic psp battery. see if it looks "swollen" or bigger than normal. if so you need a new battery. theres no way to fix it... or it can be REAAALLYY drained and just needs time to charge lol. also its a pandora, you need to turn your psp on before you put the pandora in the psp. plug it into the charger ( with no battery inside it ), turn psp on, then put pandora in.

yeah, I tried all the methods you listed it wouldn't work.  My battery doesn't show any signs of swelling.

I tried to charge it with a hobby grade lipo/li-ion charger but it wouldn't charge either.

Guess I'll need to get a new one
