This guide discusses operational parameters that may be observed by battery monitoring equipment used in stationary applications, and the relative value of such observations. Also discussed are the active supervisory and diagnostic tasks that this equipment may perform. While this guide does not give a listing of commercially available systems, it does provide a means for establishing specifications for the desired parameters to be monitored. The recent competitive realignments of Utility and telecommunication companies has created a need for unmanned surveillance of stationary battery systems. This guide will propose levels of battery surveillance and methods for achieving useful information for maintenance and replacement purposes. Since communications will play an issue with remote applications, a description of typical arrangements will provide additional insight. New IEEE Standard - Superseded. Monitoring and measurement of battery parameters is an important element of maintaining a fully operational battery system. This guide presents and discusses measurable parameters of batteries used in stationary battery systems and the utilization of such observations. This guide does not give a listing of commercially available systems, but it does provide a means of establishing specifications for the desired parameters monitored
