Batteries for stationary standby and for stationary cycling applications part 1: standby vs. cycling - definitions and concepts

This paper is introductory and provides a basis for understanding the fundamental differences between the two primary applications of stationary lead-acid batteries: standby and cycling. It sets the baseline for the use of the terminology, standby (not stationary) vs. cycling, power vs. energy, and charging efficiency. Application requirements define the need for fundamentally different designs and construction for power batteries and energy batteries. A typical stand-alone remote home application is used as an example to graphically illustrate daily cycling characteristics. Factors that typically limit battery life for standby and cycling batteries are discussed. Finally, available standards for cycling applications (SCC21) and standby applications (PES/SB-SCC29) are discussed.
