To comply with US recycling laws, most cameras do not use a "battery" for memory backup. Most states require that all batteries be easily removed when the product is recycled. Instead, they use a large value capacitor, commonly referred to as a "Gold Cap". A charged battery will charge the capacitor which by itself draws an insignificant amount of power. Its not designed for long term backup. It's pretty much assumed that most people leave a battery installed in the camera. My G9 draws <1ma of power, so the battery's on the shelf natural discharge is probably greater than the amount of power the camera consumes keeping the cap charged.
