Storage batteries play an essential role in many sectors of industry and commerce, not least as convenient sources of standby power. All too often however, stationary battery systems receive little attention after installation – in many cases, testing is carried out infrequently, if at all. A new publication from Megger, “The Battery Testing Guide” explains the risks associated with neglecting battery installations and describes practical, cost-effective measures that can be taken to minimise these risks.

The 32-page A4 format publication is comprehensive in its scope. After discussing why back-up batteries are needed and where they are used, it gives a concise overview of the main battery types and the various failure modes associated with each type. Battery maintenance philosophies are then examined and contrasted, with particular reference to the recommendations embodied in the IEEE 450, IEEE 1188 and IEEE 1106 standards.

The largest section of the publication is devoted to practical methods of testing, and is designed to help battery users to optimise the performance, reliability and life of their installations.

Discharge testing, which is the only definitive way of establishing battery capacity, is fully covered, as are impedance test methods, which often provide a faster and more convenient approach for regular routine testing. Techniques for locating ground faults rapidly and conveniently without the need to sectionalise the battery installation are also described.

The guide concludes with a useful selection of frequently asked questions, and a brief overview of Megger products that have applications in the testing of battery installations.

With its new Guide to Battery Testing, Megger has been successful in bringing together, in a single compact and clearly presented publication, all of the essential information needed to understand, test and maintain stationery battery systems. The Guide will, therefore, undoubtedly prove to be an indispensible aid for all of those who work with batteries.
