You’re not going to get more energy out then it takes to flip the battery. I cant see this producing enough power to do anything other than power a pocket calculator.
Yeah, it smells a little like perpetual motion.
If a car battery powers the car, and also powers the act of flipping the battery, then the power could be limitless (barring chemical degradation of the materials).
I don’t think the Thermodynamic gods will approve.
Pocket calculator??? It wouldn't even power a pocket watch for a couple of seconds. If the battery weighed half an ounce (an AAA cell) and you flipped it over a distance of 3 inches, you would add 1/128 ft-lb of energy to it. Since 1 ft-lb is 4x10^-7 kWh, it would take 8 million of these flips to get 1 kWh - a dime's worth of electricity.
