This recommended practice defines the areas of recommended knowledge for installers and maintainers of stationary batteries and related systems to the extent that they affect the battery. Design of the dc system and sizing of the dc battery charger(s) are beyond the scope of this recommended practice. This document covers lead-acid and Nickel-Cadmium battery technologies. The purpose of this recommended practice is to provide an outline of the necessary items that should be covered by those developing training programs for stationary battery installation and maintenance personnel. The order in which the items in this document are covered is at the discretion of the training developer/provider. New IEEE Standard - Superseded.
