Touching a corroded battery is not ideal at all. Corroded battery terminals can result in chemical burns if you touch them. The chemical burns may not be immediately obvious, but its symptoms would surface after a few minutes or hours. Some of such symptoms include; redness of the skin, blackened skin, and skin irritation. So, to avoid any of such problems, avoid touching the corroded areas of a battery’s terminals. If you need to clean them, ensure to be extra careful and use protective materials like hand gloves.
