This guide describes methods for selecting the appropriate type of valve-regulated, immobilized-electrolyte, recombinant lead-acid battery for any of a variety of stationary float applications. The purpose of this document is to ensure that the reader is aware of all significant issues that should be considered when selecting VRLA batteries, so that the user might make an informed decision.
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.
Many organizations have established standards that address lead-acid battery safety, performance, testing, and maintenance. Standards are norms or requirements that establish a basis for the common understanding and judgment of materials, products, and processes.
Valve Regulated Lead-Acid Batteries Only authorized and trained personnel familiar with battery installation, preparation, charging, and maintenance should be permitted access to the battery. SHOCK HAZARD – Do not touch un-insulated battery, connectors or terminals.
Although the AT and ATL series of batteries are valve regulated the do produce minimal gas emissions during normal operation. If exposed to abnormal high voltage charging, the cells may vent potentially explosive Hydrogen gas. Hydrogen gas when accumulated in a confined area that exceeds four (4%) percent by volume in air is explosive.
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.
However, if subjected to excessive over- charge voltage, hydrogen and oxygen can be vented into the atmosphere. Therefore, lead acid batteries should never be installed in an airtight enclosure. Sufficient precautions must be taken to prevent excessive overcharge and containment of potential explosive off gases.
