ILZRO-sponsored field data collection and analysis to determine relationships between service conditions and reliability of VRLA batteries in stationary applications

PDF Version Also Available for Download.

Description

Although valve-regulated lead-acid (VRLA) batteries have served in stationary applications for more than a decade, proprietary concerns of battery manufacturers and users and varying approaches to record-keeping have made the data available on performance and life relatively sparse and inconsistent. Such incomplete data are particularly detrimental to understanding the cause or causes of premature capacity loss (PCL) reported in VRLA batteries after as little as two years of service. The International Lead Zinc Research Organization (ILZRO), in cooperation with Sandia National Laboratories, has initiated a multi-phase project to characterize relationships between batteries, service conditions, and failure modes; establish the degree ... continued below

Description

Although valve-regulated lead-acid (VRLA) batteries have served in stationary applications for more than a decade, proprietary concerns of battery manufacturers and users and varying approaches to record-keeping have made the data available on performance and life relatively sparse and inconsistent. Such incomplete data are particularly detrimental to understanding the cause or causes of premature capacity loss (PCL) reported in VRLA batteries after as little as two years of service. The International Lead Zinc Research Organization (ILZRO), in cooperation with Sandia National Laboratories, has initiated a multi-phase project to characterize relationships between batteries, service conditions, and failure modes; establish the degree of correlation between specific operating procedures and PCL; identify operating procedures that mitigate PCL; identify best-fits between the operating requirements of specific applications and the capabilities of specific VRLA technologies; and recommend combinations of battery design, manufacturing processes, and operating conditions that enhance VRLA performance and reliability. This paper, prepared before preliminary conclusions were possible, presents the surveys distributed to manufacturers and end-users; discusses the analytic approach; presents an overview of the responses to the surveys and trends that emerge in the early analysis of the data; and previews the functionality of the database being constructed. The presentation of this paper will include preliminary results and information regarding the follow-on workshop for the study.
