Batteries play a critical role in our lives. However, depending on their chemical compositions and contents, they may turn into serious threats for both humans and the environment. Misuses and high temperatures during the operations may result in cell cracks and release hazardous liquids and gasses.
Acid burns to the face and eyes comprise about 50% of injuries related to the use of lead acid batteries. The remaining injuries were mostly due to lifting or dropping batteries as they are quite heavy. Lead acid batteries are usually filled with an electrolyte solution containing sulphuric acid.
The lead acid battery works well at cold temperatures and is superior to lithium-ion when operating in sub-zero conditions. Lead acid batteries can be divided into two main classes: vented lead acid batteries (spillable) and valve regulated lead acid (VRLA) batteries (sealed or non-spillable). 2. Vented Lead Acid Batteries
Sulphuric acid electrolyte spilled from lead acid batteries is corrosive to skin, affects plant survival and leaches metals from other landfilled garbage. Therefore, lead acid batteries are considered as hazardous waste and shall not be placed into regular garbage.
Vented lead acid batteries vent little or no gas during discharge. However, when they are being charged, they can produce explosive mixtures of hydrogen (H2) and oxygen (O2) gases, which often contain a mist of sulphuric acid. Hydrogen gas is colorless, odorless, lighter than air and highly flammable.
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.
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?
Batteries play a critical role in our lives. However, depending on their chemical compositions and contents, they may turn into serious threats for both humans and the environment. Misuses and high temperatures during the operations may result in cell cracks and release hazardous liquids and gasses.
