    I've heard of this happening before with bad batteries.

    your battery is probably defective, go to Apple and get it replaced! :)

    I will have to buy a battery because my warranty is out.

    This happened to me, I took it to the apple store and they told me it was a defective battery. They replaced it then and there and the problems been fixed ever since.
