Industrial and consumer batteries are subject to normal and abnormal aging and also to occasional manufacturing defects. Battery tests and maintenance programs are essential to ensure reliability. Several batteries testing techniques are available both on-site and remotely, each with different costs, as well as with technical strengths or weaknesses.
It is possible to set optimized maintenance timings if you consider: the criticality of the site, the age and the size of the battery, the results of previous tests, the programs and tests procedures. All that can be used to optimize the life and performance of permanently installed lead-acid batteries used for standby service. The result the result is achievable thanks to a combination different techniques and thanks to distribution of all these events dynamically during the battery life cycle.
These are the technical rules stated in "IEEE 450-2010 IEEE Recommended Practice for Maintenance, Testing, and Replacement of Vented Lead-Acid Batteries for Stationary Applications". The IEEE assures the best-known standards for UPS battery maintenance practices, including inspections and capacity testing. Battery manufacturers often cite those standards and require membership to maintain a valid product warranty.
Regardless of whether it is a data center, industrial facility, or utility, adherence to the following standards is encouraged, based on the type of battery to be overhauled: IEEE 450 for lead-acid 8VLA9 IEEE 1188 for valve-regulated lead-acid 8VRLA; IEEE 1106 for nickel-cadmium (NicCad).
All of these standards provide recommended practices for maintenance, testing, and replacement of batteries for stationary applications. They address the frequency and the type of measurements that need to validate the battery condition. Adelsystem has developed an integrated battery tester inside the battery charger. It is an efficient concept that can work with all types of batteries. We talk about this technology and its application in this article. We talk about Battery Care Concept!
