The Canon Powershot A590 IS is an 8 megapixel digital point-and-shoot camera with a 4x optical zoom and a 2.5 inch LCD screen.
ok is there a second tiny round battery in there and what does it do or affect the camera and how do i find a replacement
Is this a good question?
That is the RTC "real Time Clock" battery. It maintains all your date and time as well as other settings. That way, even if you change the main batteries, all data and setting remain. Check on here to see how to change it.
