Its normal for a bad battery to smell like rotten eggs. Its also a toxic chemical that can kill you. If its your truck, get new batteries. It its not your truck park away from it.
Can't be. My truck doesn't have batteries in it. They are currently on the charger in the garage to find out if one is bad or if i just left something on to drain them.
