Hello. My name isXXXXX will be your Primary Care Technician and I can assist you with your question.
What has most likely happened is that the battery was damaged. Don't worry though, a replacement is very inexpensive. Here is a link to one.

Ok. See. So the camera itself was likely damaged with the wrong charger.
If the camera isn't working and you are certain that the new battery is correct, then you will have to have the camera serviced.
