This can cause throat and sinus irritation or even be lethal in high enough concentrations. ... If the overcharge is minimal and you have a sealed lead-acid battery, then you will likely not even notice a ...
How Lead-Acid Batteries Work
When the battery is discharged, the sulfuric acid reacts with the lead to create lead sulfate and hydrogen ions. This releases electrons, which flow through an external circuit to power a device. When the battery is charged, the reaction is reversed, with the lead sulfate and hydrogen ions recombining to create sulfuric acid and lead.
BU-703: Health Concerns with Batteries
Lead acid produces some hydrogen gas but the amount is minimal when charged correctly. Hydrogen gas becomes explosive at a concentration of 4 percent. This would only be achieved if large lead acid batteries were charged in a sealed room. Over-charging a lead acid battery can produce hydrogen sulfide.
Lead Acid Batteries
A sealed lead acid (SLA), valve-regulated lead acid (VRLA) or recombining lead acid battery prevent the loss of water from the electrolyte by preventing or minimizing the escape of hydrogen gas from the battery. In a sealed lead acid (SLA) battery, the hydrogen does not escape into the atmosphere but rather moves or migrates to the other ...
Why Does My Battery Smell Like Sulfur When Charging?
However, understanding why the battery emits this odor and taking preventive measures can help eliminate or reduce the smell. When a battery is being charged, a chemical reaction occurs inside the battery, converting lead and sulfuric acid into lead dioxide and lead sulfate. During this process, the battery releases hydrogen gas.
