IEC 60896-21:2004

Applies to all stationary Lead-Acid cells and monobloc batteries of the valve regulated type for float charge applications (i.e., permanently connected to a load and to a DC power supply), in a static location and incorporated into stationary equipment or installed in battery rooms for use in telecom, UPS, utility switching, emergency power or similar applications. The objective is to specify test methods for all types and construction of valve regulated stationary Lead-Acid cells and monobloc batteries used in standby power applications.
