IEC/TR 62540@ which is a technical report@ applies to all stationary lead-acid cells and monobloc batteries for float charge applications (i.e. permanently connected to a load and to a d.c. power supply)@ in a static location (i.e. not generally intended to be moved from place to place) and incorporated into stationary equipment or installed in battery rooms for use in telecom@ uninterruptible power supply (UPS)@ utility switching@ emergency power or similar applications. These batteries are covered by IEC 60896-11@ IEC 60896-21 and IEC 60896-22. The objective of this technical report is to assist the supplier and user of radio frequency identification devices (RFID) in the understanding of the requirements for performance@ durability@ data content and structure@ the write ead capability of such devices@ and to provide guidance so that the RFID tag on the battery will result in meeting the needs of a particular industry application and operational condition. This technical report does not directly apply to lead-acid cells and batteries used for vehicle engine starting applications (IEC 60095 series)@ solar photovoltaic applications (IEC 61427)@ or general purpose applications (IEC 61056 series) but nevertheless can also be the base of standardization activities for these types of lead acid batteries.
