This is a wet-cell battery made by Exide. Scientists and engineers developed several commercially important types of battery. Wet cells were open containers that held liquid electrolyte and metallic electrodes. When the electrodes were completely consumed, the wet cell was renewed by replacing the electrodes and electrolyte. Open containers are unsuitable for mobile or portable use. Early electric cars used semi-sealed wet cells.
