The correct answer is: C. A carbon-zinc cell has unlimited shelf life.
A storage cell is a type of electrochemical cell that can be recharged. A lead-acid cell is a type of storage cell that is commonly used in cars. A carbon-zinc cell is a type of primary cell that is commonly used in dry batteries. A primary cell has an irreversible chemical reaction, which means that it cannot be recharged.
A carbon-zinc cell has a limited shelf life because the zinc electrode will eventually corrode. The shelf life of a carbon-zinc cell can be extended by storing it in a cool, dry place.
A lead-acid cell has a longer shelf life than a carbon-zinc cell because the lead electrodes are less likely to corrode. The shelf life of a lead-acid cell can be extended by storing it in a cool, dry place and by not fully discharging the battery.
A storage cell has a longer shelf life than a primary cell because the chemical reaction in a storage cell is reversible. This means that the battery can be recharged and used multiple times.
