hunting-addict: If you check back 3 or 4 pages, there is a post by the member heinz57 as "What type of c batteries", on 07-06-2010, 11:48 P.M. I replied to it. I'm using these in Spy Point IRB (C batteries), 2009 Bushnell Trophy Trail camera (AA batteries) and WildView EZ Cam (C batteries). The Bushnell and Spy Point are set for 30 second video with 10 second delay. The WildView will only take pictures in a 3 shot burst. Spy Point and Bushnell, the batteries stand up good with Bushnell being the best. WildView can be easy or hard on batteries. This camera is tempermental. The rechargeable batteries are by Pure Energy. They are expensive, but once you have them, there is a great savings.
