I JUST GOT MY NEW ALKALINE BATTERY POD AND DO NOT KNOW HOW TO OPEN IT. IT HAS TWO SMALL HOLES ON OPPOSITE SIDES, AND I CAN SEE TWO SCREWS. BUT THERE IS NO GROOVE THAT A SCREW DRIVER WILL FIT, LIKE A STANDARD OR A PHILLIPS. IT LOOKS AS IF THERE ARE TWO METAL CAPS THAT ARE COUNTER SUNK. I HAVE NO IDEA HOW TO OPEN IT, AND DO NOT WANT TO DAMAGE IT. PLEASE HELP.
