MISSION CRITICAL: Reliability and Cost-Effective Solutions for Data Centers
by Eric Lehmann, Director Quality Services
"Lead-acid batteries have been a preferred method of ensuring power reliability for decades, backing up mission-critical facilities all over the world. As with any system, users are constantly looking for ways to improve on the technology to make it more cost effective and more efficient . . ."
C&D Technical Bulletins
TECHNICAL BULLETIN: Parallel Operation of Lead Acid Batteries
"Just as plates can be connected in parallel to increase the capacity of a cell, completed cells and series connected strings of cells can be connected in parallel to increase the capacity of the battery system."
TECHNICAL BULLETIN: Self-Discharge and Inventory Control
"The lead acid battery will exhibit a degree of self-discharge during periods of disuse and while on open circuit while in inventory. The rate of self-discharge for a specific design of battery is a function of grid allow, plate thickness, spacing (separator thickness), and electrolyte specific gravity."
TECHNICAL BULLETIN: Gassing and Ventilation
"The valve regulated lead acid (VRLA) battery is unique in that it incorporates an oxygen recombination cycle which occurs at the negative plate of the cell and minimizes the generation of hydrogen. As a result, the VRLA battery will typically have a recombination rate of 95 to 99% and will emit only a very small fraction of the hydrogen as would be emitted by a vented (wet) lead acid battery."
TECHNICAL BULLETIN: Charging Valve Regulated Lead Acid Batteries
"The preceding information is presented to assist the engineer in the design of an appropriate charging system for the VRLA battery in specific applications. No one charging scheme is optimum for all applications, and it is up to the designer to select those charging techniques which is most appropriate for the specific battery application and are optimum from a battery performance, life and economic standpoint."
