IEEE 450-1972

This document is limited to providing recommended practices of maintenance. test schedules. and testing procedures that can be used to optimize life and performance from large lead storage batteries. It also provides indications to determine when batteries should be replaced. There are other test procedures and replacement techniques used within the industry (especially for smaller substation batteries) that are equally as effective but arc beyond the scope of this document. Sizing. installation, other battery types. and application are also beyond the scope



Revision Standard - Superseded. Proper maintenance will prolong the life of a battery and will aid in assuring that it is capable of supplying its design power requirements. A good battery maintenance program will serve as a valuable aid in determining the need for battery replacement. Station battery maintenance should be performed by personnel knowledgeable of batteries and the safety precautions involved.
