[This introduction is not a part of IEEE Std 1189-1996, IEEE Guide for Selection of Valve-Regulated Lead-Acid (VRLA) Batteries for Stationary Applications.]

Valve-regulated lead-acid (VRLA) batteries are playing an ever-increasing role in control and power systems, for stationary reserve use in electric utilities, telecommunications, and uninterruptible power systems. In many cases, VRLA batteries are being substituted for vented lead-acid batteries. Their use is also expanding into many other applications where their unique characteristics appear attractive. Both gelled electrolyte and absorbed electrolyte VRLA designs, covering a range of sizes and capacities, are now available for use in many traditional and nontraditional battery applications. This guide fulfills the need within the industry to provide common understanding on VRLA cells and is applicable to all installations and battery sizes.

Scope

This guide describes methods for selecting the appropriate type of valve-regulated, immobilized-electrolyte, recombinant lead-acid battery for any of a variety of potential stationary float applications. Installation, maintenance, sizing, and consideration of battery types other than valve-regulated lead-acid batteries, are beyond the scope of this guide. Design of the dc system and sizing of the dc battery charger(s) are also beyond the scope of this guide.
