if the batteries just a bit tight, just slam the open end into the palm of your hand and that should get it loose. if it still won't come out enough to get ahold of it, do the same only hit the hand holding the body into your other hand. if for some reason this can't get it out, then you'll have to take the other end of the body off and push it out. if you need to go that far, you probly have some other issues then that will be appearent when you have it apart.
