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?
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
• 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.
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 battery case and relieve excessive pressure. But when there’s no vent, these gasses build up and concentrate in the battery case.
Overcharging, or lead acid battery malfunctions can produce hydrogen. In fact, if you look, there is almost always at least a little H2 around in areas where lead batteries are being charged. Overcharging, especially if the battery is old, heavily corroded or damaged can produce H2S.
Add water to a lead-acid battery after charging. Adding water before charging isn’t a good idea because the water may expand during charging. And this can cause the electrolyte to boil over and spill out. You should abide by the following safety tips to reduce the risk of injury when adding water to a lead-acid battery: Wear appropriate safety PPE
