Potato and lemon batteries will last as long as the electrolytes are present and the electrodes are intact. The battery won’t work if the potato or lemon dries out or if an electrode dissolves.The ions in acids ( H+ or protons) are part of the chemical reaction that helps to produce electricity. Why is it important that the electrodes do not touch each other inside the lemon? If the electrodes touch each other then you’ll “short circuit” the battery and it won’t work.A potato delivers a higher power (more Watts) than a lemon in both parallel and series circuits.
