cj7zrcool,---We have been useing the 6v 5Ah rechargable batteries with all of our Moultrie cams and we easly get 30 to 40 days with 20 to 50 pictures per week. We use the standard Moultrie solar panel and point it at the morning sun (this is very important). The batteries were purchased from our local Battery Plus outlet and the brand name is Werker. Other tips for trail cameras and reviews of most cameras can be viewed at www.chasingame.com. come visit us Bill
