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.
Ventilation of battery rooms or cabinets shall be in accordance with with National Regulation and/or IEC/EN 62485-2. Internal resistance can be important to the equipment design and operation. The manufacturer shall state the value of internal resistance for a new battery.. This item is covered by chapter 6.3 of IEC/EN 60896-21 and -22.
In addition, cabinets with VRLA batteries have a separate requirement to identify the details of the battery system, electrical, chemical and fire hazards. Remember New York City B-29 Certificate of Fitness requires a specialized sign kit for all five boroughs.
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.
VRLA (Valve Regulated Lead Acid) batteries are lead batteries with a sealed safety valve container for releasing excess gas in the event of internal overpressure. Their development was aimed at limiting the emission of hydrogen into the atmosphere and to avoid the use of liquid electrolyte.
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.
What is VRLA Battery?
A VRLA (Valve Regulated Lead Acid) battery is a type of rechargeable battery that is sealed or maintenance-free. A lead acid battery is essentially made up of lead-acid cells connected in series inside of a single container. These cells have two lead plates submerged in a sulfuric acid electrolyte solution. The battery converts the lead plates into lead sulfuric oxide to …
