Camera does not recognize the battery.

I am getting an error message saying the camera does not recognize the battery. Its a canon battery. I have tried several and get the same message. The camera does turn on and function but I have no way of telling how much power is left. Is this fixable and can I continue to use the camera wthout damaging it?
