Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Leave the camera Off, with batteries removed, for at least overnight.
Then put batteries in, hold down the Eject button, and power it On, still holding down the Eject button for at least 30 seconds.
How old is your Canon ZR200 camera?
Is the battery a rechargeable, or non-rechargeable?
If it is rechargeable, try removing it from the camera, and charging it on the charger for another 6 hours continuously. If the charging is done with it in the camera, leave it in the camera and charge for 6 hours without turning the camera On in that interval.
