It uses a 9V battery. When I replace a Smoke Alarm battery I put Scotch Tape over the Terminals and store them in a empty Mayonnaise jug so I can use them for the Pig. Oh, have to tell a story; a Serviceman came to our house to repair the refrigerator. When he opened the refrigerator door and heard the Pig oinking he told us he never heard a refrigerator make that kind of noise. Then I showed him the Pig. I was wondering what is the Part Number of the Lithium battery you've been writing about? I want to see that critter.
