Hi Gordon. Welcome to justanswer.
How old is your camera?
Gordon, is it possible to return?
If you can return it somehow then that would be the best thing to do. There is some defect either in the battery or in the battery circuitry.
Is the battery charging properly?
Gordon, if you are not able to return it then don`t worry as it would still be covered under warranty. So you can get it repaired for free from Canon. Let me know if you have any query.
