pandora battery puzzle

I have an original pandora battery which i have used successfully three times b4, the last time about 18 mths ago I got it out to downgrade a psp1003 phat somebody had upgraded to 5.51. I charged it, put battery in then magic stick in and it boots up like ordinary battery,tried other sticks just the same
Anybody any idea
Cheers
