Field-installed battery interconnections are largely misunderstood on several levels. These include pre-assembly preparation, use of corrosion inhibitors, the essential need for insulated tools, including a torque wrench, and verification of connection integrity. The author will take attendees to school on these important fundamentals.
After a battery system has been installed, it is vitally important to verify it is actually ready to be placed into final service. Connection tightness and integrity, proper cell polarity, and initial charge are just a few of the checks that need to be done to ensure the battery will deliver power when called upon. All too often, these and other pre-operational checks are never performed, leaving the end user wide open for potential failure of the very system that is expected to work when everything else fails. This paper will discuss typical commissioning requirements and pitfalls users need to avoid. Applicability is focused on both VLA and VRLA batteries.
From time to time, stationary batteries may exhibit anomalies that require corrective action in the course of their operation. Some of these are easily correctable, while others require some detective work to solve. Sometimes a problem is not with the battery, rather, it may be the manner in which it is being tested or maintained by the user. This paper identifies some common and some not so common problems the user may encounter. VRLA and VLA battery types will be discussed.
Maintenance staffers responsible for measuring and recording battery operating parameters know they are supposed to be taken on a periodic basis. After years in the business, it is clear that little or nothing is frequently done with the readings post-inspection. Technicians think Engineering is analyzing the data. Or, is it that Engineering is supposed to be doing this? In reality, no one is doing anything with the data and, in the meantime, potential battery failure waits. When data is analyzed, it’s frequently misinterpreted. So, what are you doing with the data? This paper will discuss commonly measured battery parameters, what the data mean and good sources of guidance for what the readings should look like.
Battery field service technicians are faced with decisions on a daily basis that affect continued operational status of this vitally important subsystem. This paper discusses several popular “nuts and bolts” topics and related questions the author routinely is asked in training classes.
There is a lot of confusion over some basic concepts relating to testing stationary batteries. This paper is intended to answer a number of common questions relating to ratings, specifications, and the fundamentals of discharge testing a battery system.
