Query: Terrible battery

I can not say anything positive about this battery except that it has not exploded. Yet.It will charge up, work for a brief time with a 100% charge according to the camera meter, then quickly stop working 30 seconds after telling me the battery is low. Interestingly, if i take it out and put it back in, or shake my camera, I can *sometimes* get it to work (and the camera says its charged). The day after getting it, I made the huge mistake of forgetting it was in my camera...thinking the original was in place. As a result, it failed at a critical moment and I missed getting a good shot of my daughter's graduation. I hold myself responsible as I bought this piece of junk. I cant find the original packaging, and at this price its probably not worth the effort to send it back.
