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.
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.
For lead-acid batteries, adequate ventilation is crucial to prevent the build-up of hydrogen and oxygen gases, which are byproducts of the battery's operation. Without decent ventilation, these gases can result in an increase in pressure within the battery, posing a safety risk.
Since hydrogen and oxygen can be flammable, you need to be cautious when storing or recharging a lead acid battery. Make sure to store lead acid batteries in a well-ventilated area that's located away from any sparks or open flames. You also want to be sure to keep the vent cap free of any obstruction.
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.
This danger can be eliminated by monitoring hydrogen build-up and providing adequate ventilation. Battery manufacturers should be able to provide exact gassing rate, charging voltage and charging currents for the type of battery installed. How much hydrogen does a battery emit?
