    Any other users notice just how awesome the D40's battery life is? This battery never runs out, its just keeps going and going. I can't even remember the last time I charged its battery. What to other D40 users think of it's battery life?

    Very Long

    I just returned from a trip for which I bought my first digital slr - a D40. I didn't want to have the battery deplete so I purchased a second one. It was not necessary.

    I was actually glad when the camera showed that a bar on the battery symbol was gone. I was beginning to think that function was broken.

    In general, it'll go through a full day of shooting without any problems. We have a back-up battery as a matter of principle but have had to use it only once or twice.

    Same with the D50 - battery lasts through a full day of shooting, the back-up battery gets used only rarely.

    The others........ back-ups are a good idea, unless you're using a battery grip with a second battery.

    I bought a couple 3rd party batteries from ebay. Even they manage to keep going for hundreds of shots. I'm flash phobic, but I assume my anti-shake must suck up some power?

    The thing tht I love is that accidentally leaving it switched on has minimal effect on the battery.

    Leaving the D40 On

    According to Ken Rockwell, "Leave it ON unless you're putting it away. It draws no more power in ON than OFF. OFF is a lock to prevent accidental operation." http://www.kenrockwell.com/nikon/d40/users-guide/controls.htm

    I still tend to turn the camera off but am doing so less often while shooting. My experience is like yours and seems to confirm Ken's statement: No noticeable drain on the battery when the camera is left "on."
