This is basic chemistry, a chemical reaction between metals, acid, and salt, producing metal oxides (in this case zinc oxide and copper oxide) and hydrogen gas (H2). Power is used to light an LED, a buzzer (or piezoelectric speaker), and helps recharge a AAA rechargeable battery. What happens to this battery several days later?
