Meeting the challenges of the distributed power environment

The movement from the central office to a distributed power architecture results in both changes in how batteries are used and their environment. The location of batteries with electronic equipment drives the use of VRLA products and contributes to the requirement for products that will endure higher temperatures. Batteries in distributed systems will, in all probability, experience more frequent and more severe usage. However, improvements in VRLA technology and new products entering the market provide increased options and the opportunity to select the right product for these applications. Tubular lead/acid products represent one of these options and should be considered when deep and/or extensive cycling is required. Cycle life in excess of 1200, 100% depth-of-discharge cycles have been demonstrated. While the higher temperatures encountered in these uncontrolled environments arguably present the greatest challenge to battery life, improvements have been made that enhance resistance to thermal-runaway and increase float life at elevated temperatures.
