Hey Guys right now I have the G42NG camera and it's been going through batteries fairly quickly. I also noticed when the camera is at around 40 percent it won't take night time pics. Is this normal? The camera is around a year old. I have always used alkaline batteries but thinking the lithiums might be the way to go? Does anyone have any experience with lithium batteries and is there a reliable place to order them in bulk to save a few bucks?
