There are few things more unpleasant and bothersome than the smell of rotting eggs emanating from your vehicle. Because of this revolting smell, you may start to question if you accidentally left eggs in the car. It may come as a surprise, but the battery is usually the source of that spoiled egg stench.
Why does my car battery smell like rotten eggs
Batteries that contain lead acid, such as those used in marine applications, golf carts, forklifts, cars, and other vehicles, can emit an odor similar to that of a long-forgotten spoiled egg odor in a vehicle.
The two lead plates in these lead-acid batteries are immersed in sulfuric acid. Through chemical reactions involving sulfuric acid and lead plates, the battery generates electricity that powers the vehicle’s starter and other electrical components.
The battery releases sulfate when it loses charge. The sulfate dissolves back into the battery when it is recharged. The efficiency and lifespan of the battery will be reduced as the sulfate clings to the lead plates after an extended period of not being recharged.
You can smell rotten eggs coming from your car battery because the sulfate in it reacts with moist air.
Overcharging, overheating, leaking, or using a faulty battery charger are typically the most prevalent causes of a battery odor, whether it is old or new.
