I use the Energizer Rechargable batteries in my 2 Moultrie I-60 trail camera's...they work fairly good and I actually have 3 sets (18 total batteries) I keep 1 set of 6 batteries in each camera and I have 1 extra set that I charge up and carry with me when I think one of the camera's are getting low.They last a good while if I don't set the camera on video.The best batteries I have used were the Duracell copper-top batteries,I put a set of 6 in my Moultrie in our clodest months of Jan and it lasted for 4 months til the end of April with around 35% still left on it but I changed it out so it didn't go dead on me in the middle of the month.
