Installation Design for Valve-Regulated Sealed Lead-Acid Batteries in Generating Stations
Commercially available large-capacity valve-regulated sealed lead-acid batteries represent a novel technology for large stationary batteries for emergency power applications, using an oxygen recombinant cycle to inhibit the generation of hydrogen under normal operation. A discussion is presented of the installation design for these batteries, making comparisons to traditional vented lead-acid cells as appropriate. The operation of the valve-regulated sealed lead-acid battery is also described. >
Sealed Lead-Acid Batteries Operational Experience in a Telecommunication Service Application
Sealed lead acid batteries have been under evaluation by British Telecom for the past 7 years. This evaluation has not been confined to the Laboratory, but has included significant product performance evaluation under actual service conditions both in the public switched telephone network (PSTN) and at customer based PABX installations. This paper will discuss important areas of operational experience in a telecommunications environment, and the manner in which some of the data has been used to suggest product improvements and provide users with a long term confidence in the use of this relatively new technology.
Lead-acid battery: Reserve batteries for bell system use: Design of the new cell
A new cylindrical lead-acid battery has been developed to provide reserve power to sustain telephone service during power-failure conditions. We discuss in this paper the usage of batteries in the modern telephone plant, review the difficulties encountered with existing cell designs, describe in detail special features of the new design, and outline the scope of the overall development program.
