Is spill containment required for standby power systems utilizing VRLA batteries?
Rather than a flooded battery in which the electrolyte is a free flowing liquid, a VRLA battery (valve-regulated lead acid) uses an absorbent glass mat technology or fiberglass mat to immobilize the electrolyte. Consequently, there is far less liquid in a VRLA battery. In fact, Doug Frazier, president of EnviroGuard, is a member of several committees of the IEEE (Institute of Electrical and Electronics Engineers) and has repeatedly opposed the need for spill containment for VRLA systems. However, state and local ordinances often mandate spill containment for these systems despite industry opposition of such requirements. You should check your local ordinances to see what is required.
