In sealed lead-acid batteries it normally is absorbent glass fiber to hold the electrolyte in suspension. Sealed lead-acid battery, generally having the following charac-teristics: Maintenance-free, leak-proof, position-insensitive. Batteries of this type have a safety vent to release gas in case of excessive internal pressure build-up.
All lead acid batteries, including VRLA batteries, produce hydrogen and oxygen gases during normal charging. Even though VRLA batteries are designed to recombine these gases internally, the recombination efficiency is less than 100%. Small amounts of hydrogen and oxygen are released from the pressure relief valve during charging.
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.
For instance, deep cycle flooded lead acid batteries contain antimony in the grid alloy which causes a high rate of self discharge and rapid water loss due to gassing reactions. The escape of hydrogen and oxygen from the battery represents a serious safety hazard if the gasses are not ventilated properly.
