The alternator produces power to charge the battery. The battery powers the starter to turn the engine over.
If the alternator fails, it is no longer keeping the battery charged and your engine is running on nothing but battery power. Once the battery runs down, your engine will no longer run.
If an automobile battery is in normal condition, there should be very little smell from it. The one smell that you should be aware of is the smell of rotten eggs, which indicates severe and dangerous problems with the battery. Once a battery begins to smell like rotten eggs, it cannot be saved, but must be immediately replaced. Please be aware that rotten-egg batteries can explode. Rotten-egg batteries are frequently much hotter than normal batteries would be, and the hot rotten-egg batteries are the most dangerous. The most common cause of rotten-egg batteries is an alternator which constantly overcharges, so the alternator should usually be replaced along with the battery.
