NON-RECHARGEABLE BATTERY

"A battery in which the chemical reaction system providing the electrical current is not easily ""chemically"" reversible. It provides current until all the chemicals placed in it during manufacture are used up. It is discarded after a single discharge. Also called ""primary"" battery or cell. Contrast with rechargeable battery. See also an Encyclopedia Article. This battery always operates as a galvanic cell. Consequently, the anode is the negative electrode, while the cathode is the positive electrode. "
