fasterem: In my area, that would be an awful lot of pictures, especially in two to three weeks. I don't have many animals moving around, due to lots of food and water. In other words, they don't have to travel far. For me to get any amount, I have to have vegetation, tree movement to trigger any amount. For that number of pictures, I would think the batteries are standing up fairly well. With you using the solar panel, this would help out. Have you been having much cloudy weather? Up here in southern Manitoba, Canada, we haven't had much sun, lots and lots of rain, so this would have a great effect on a solar panel. I had one 2009 Bushnell set up for security. In 8-10 days, I had 108 each 30 second videos with a 10 second delay. Some of the videos showed wildlife movement: deer, birds, gophers etc. It also caught me at various times working around the yard and mowing grass. There was also quite a bit of vegetation movement due to wind. The batteries are standing up well in these cameras, but apparently from reviews they are easier on batteries. A couple other 2009 Bushnell cameras captured around 65 videos in 8-10 day period with the same settings. What I did find if there was a lot of videos taken in one or two days, the batteries needed a bit more time to recover. Instead of taking 30 second videos, some had dropped to 10 or 11 second and I even had a couple of 6 second ones, later recovering back to 30 second.
This however isn't a fair comparison due to two different camera brands.
Hopefully some of the members that are using the same make of camera as yours, will chime in, giving examples of the amount of pictures or videos they have been getting and approximate battery life.
