Yes, the batteries and the SD card are stored in the same compartment in the bottom of the camera. If you try and force the battery door to close and lock when it's not in position, you'll probably break it. That's what people do. The door is only plastic. If you open and close the battery door carefully and slide it into the locked position without forcing it, you'll be OK. I've had my Canon for two years and have not had any problems with the door, and I've changed the batteries and SC card more time than I can remember.
