Valve-regulated lead-acid (VRLA) batteries are playing an ever-increasing role in control and 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 are desirable.
This guide to IEC/EN standards aims to increase the awareness, understanding and use of valve regulated lead-acid batteries for stationary applications and to provide the ‘user’ with guidance in the preparation of a Purchasing Specification.
Stationary Lead Acid Batteries – Valve regulated types, published in 1995. Types – Requirements, in February 2004. 60896-21 and –22 Standard designations received the EN (European Norm) prefix with identical numbering. Within a period choice and their voluntary implementation started.
In this revision, particular reference is made to ‘General Definitions’, ‘Product Characteristics’, ‘Design Life’, ‘Service Life’ and ‘Safety’. A valve regulated cell or battery is closed under normal conditions by a non-return control valve that allows gas to escape if the internal pressure exceeds a predetermined value.
Excessive ripple on the DC supply across a battery has the effect of reducing life and performance. It is recommended, therefore, that voltage regulation across the system, including the load, should be better than +/- 1% between 5% to 100% load, without the battery connected and under stable state of conditions.
IEEE Std 1189TM, and IEEE 485TM, it will provide the user with a general guide to selection, sizing, designing, installing, and testing a VRLA battery installation. Errata, if any, for this and all other standards can be accessed at the following URL: http:// standards.ieee.org/reading/ieee/updates/errata/index.html.
