Tech Note | Battery Spill Containment is Not required for VRLA Batteries


Almost all non-Institute of Electrical and Electronics Engineers (IEEE) battery related codes were written with the Vented Lead-Acid (VLA) in mind. VLA is the correct IEEE term for a battery that has free-flowing, liquid, dilute sulfuric acid electrolyte that allows gases generated during charging to be vented out of the battery. Because of this design, precautions were put in place to both protect against electrolyte spills and the effects of gas evolution from the battery.

This technical note will explore all the reasons why.
