Scope : This part of IEC 60896 bear  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 d.c. power supply), in a static location. These batteries are  not generally intended to be moved from place to place and incorporated into stationary equipment or installed in battery rooms for use in telecom, UPS or similar applications.

Objective: The objective of this part of IEC 60896 is to guide the specifier in the understanding of the purpose of each test contained within IEC 60896-21 and provide instructions on a suitable requirement that will result in the battery meeting the needs of a particular industry application and operational condition. This standard is used in conjunction with the common test methods described in IEC 60896-21 and is associated with all types and construction of valve regulated stationary lead-acid cells and monoblocs used in standby power applications.

This standard does not applies to

  • Lead acid cells & batteries used for vehicle engine starting applications
  • solar photovoltaic applications
  • general purpose applications (IEC 61056 series)
