The gases given off by a lead-acid storage battery on charge are due to the electrolytic breakdown (electrolysis) of water in the electrolyte to produce hydrogen and oxygen. Gaseous hydrogen is produced at the negative plate, while oxygen is produced at the positive. Hydrogen is the gas which is potentially problematic.
Venting is the process by which a lead acid battery releases these gasses in order to prevent them from building up pressure inside your battery. It does this through a vent cap located on the top of the battery, which allows gasses to seep through.
The important point for our purposes here is that hydrogen and oxygen gasses are both flammable and need to be removed from the battery. Venting is the process by which a lead acid battery releases these gasses in order to prevent them from building up pressure inside your battery.
• Connect via MODBUS (RS-485) or 4-20mA During charging, (especially in the event of overcharging), lead acid batteries produce oxygen and hydrogen. These gases are produced by the electrolysis of water from the aqueous solution of sulfuric acid. Since the water is lost, the electrolyte can be depleted.
When a lead acid battery cell “blows” or becomes incapable of being charged properly, the amount of hydrogen produced can increase catastrophically: Water is oxidized at the negative anode: 2 H 2O (liquid) → O2 (gas) + 4 H+ (aqueous) + 4 e− The protons (H+) produced at the anode are reduced at the positive cathode: 2 H+ (aqueous) + 2 e− → H2
The electrolyte’s chemical reaction between the lead plates produces hydrogen and oxygen gases when charging a lead-acid battery. In a vented lead-acid battery, these gases escape the lead-acid battery case and relieve excessive pressure. But when there’s no vent, these gasses build up and concentrate in the lead-acid battery case.
Lead acid battery boiling during charging: this is bad, right?
I''m an electrical engineer who could use some help understanding lead acid batteries. I recently bought an old motorcycle and charged the battery on my trusty automotive style battery charger after it lost charge. After several hours, the water was boiling inside the battery. I''m fairly certain the battery is relatively new and the water level ...
