Lead acid batteries occasionally vent sulfuric acid vapor and hydrogen gas. Corrosion can occur when these gasses react with the heat under your hood and the metal on the battery's terminals. Corrosion also results from overcharging your battery. As a battery ages, the terminals become more likely to corrode.
Yes, lead-acid batteries emit hydrogen and oxygen gases during charging. This gas is colorless, flammable, poisonous, and its odor is similar to rotten eggs. It’s also heavier than air, which can cause it to accumulate at the bottom of a poorly ventilated space. Is Battery Gas Harmful? Yes, battery fumes are harmful.
If you see corrosion your batteries are emitting very dangerous gasses. Luckily, high-quality lithium batteries like our Battle Born line do not emit any gasses and will not corrode terminals. This is just one of the reasons our batteries are so much safer than old lead-acid technology. What Happens If Battery Terminals Corrode?
Overcharging is another frequent culprit for corrosion, especially when the damage appears limited to the battery’s positive terminal. Generally speaking, anything that exposes your battery terminals to reactive materials (including bad weather) can lead to battery corrosion.
In a vented lead-acid battery, these gases escape the battery case and relieve excessive pressure. But when there’s no vent, these gasses build up and concentrate in the battery case. Since hydrogen is highly explosive, there’s a fire and explosion risk if it builds up to dangerous levels. What Is a Dangerous Level?
Lead-acid batteries use an electrochemical process to produce energy. Let’s explain this. A lead-acid battery consists of metal plates and an electrolyte solution. Now, what are the two pieces of different metals that are in contact with electrolytes in a battery? These 2 metals are:
