Possible broken pandora battery

[Sadistic Intentions]

Ok so I'm trying to charge my pandora battery and it's been awhile since I've used much less even looked at it, I was wondering if it's possible for it not to work after a long time of not charging or using it, because I'm trying to charge it and it doesn't at all, if anyone can help me with this problem, I'll gladly +rep and pay vbux or whatever, your assistance is very much appreciated.
