you got a dud. I had to send 2 back b/f I got ones that would work, but of the ones I'm running now are great. Both are I450s. Who ever told you the battery pack was that much must be on the wacky weed, go to BPS order the battery pack and they'll last a month on one charge. I've got over 1000 pics on one charge and it's shows to still be full. Mine takes excellent day and night pics, don't know if you seen my piebald photo of him standing on his back legs, but I couldn't ask anymore from a camera.
