battery
Over-charging a lead acid battery can produce hydrogen-sulfide. The gas is colorless, very poisonous, flammable and has the odor of rotten eggs. Hydrogen sulfate also occurs naturally during the breakdown of organic matter in swamps and sewers; it is also present in volcanic gases, natural gas, and some well waters.

Is The Rotten Egg Smell From A Battery Dangerous?
The smell of rotten eggs in batteries is caused by the chemical reaction that occurs when sulfuric acid in the battery breaks down. When the battery is overcharged or overheated, the excess electrical current releases hydrogen sulfide gas (H2S). This gas has a distinct smell, similar to rotten eggs or sulfur.

Do lead acid batteries accumulate sulfation?
All lead acid batteries will accumulate sulfation in their lifetime as it is part of the natural chemical process of a battery. But, sulfation builds up and causes problems when: Two types of sulfation can occur in your lead battery: reversible and permanent. Their names imply precisely the effects on your battery.
How does lead sulfate affect battery performance?
Over time, the lead sulfate builds up on the electrodes, forming hard, insoluble crystals that can reduce the battery’s capacity and lifespan. Sulfation is a common problem with lead-acid batteries that can lead to reduced performance and a shortened lifespan.
Can lead sulfate cause a battery to overheat?
In addition, the buildup of lead sulfate can cause the battery to overheat, which can further damage the electrodes and shorten the battery’s lifespan. To prevent sulfation and extend the life of your lead-acid battery, it is important to maintain the battery properly and to avoid overcharging or undercharging it.
How to prevent sulfation in lead-acid batteries?
Proper charging is essential to prevent sulfation in lead-acid batteries. Overcharging or undercharging can lead to sulfation. It is essential to charge the battery fully and avoid overcharging. A battery charger with a float mode is ideal for preventing sulfation. The float mode helps to maintain the battery’s charge level without overcharging it.
What happens if a battery is sulfated?
Sulfation occurs when a battery is deprived of a full charge; it builds up and remains on battery plates. When too much sulfation occurs, it can impede the chemical-to-electrical conversion and significantly impact battery performance. When your battery has a buildup of sulfates, the following can happen:
What happens if you swallow a lead acid battery?
(See BU-705: How to Recycle Batteries) The sulfuric acid in a lead acid battery is highly corrosive and is more harmful than acids used in most other battery systems. Contact with eye can cause permanent blindness; swallowing damages internal organs that can lead to death.
