This part of IEC 61056 specifies the dimensions, terminals and marking for all general purpose lead-acid cells and batteries of the valve regulated type for either cyclic or float charge application; in portable equipment for intance incorporated in tools, toys, or in static emergency, or uninterruptible power supply and general power supplies. The cells of this kind of lead-acid battery may either have flat-plate electrodes in prismatic containers or have spirally wound pairs of electrodes in cylindrical containers. The sulphuric acid in these cells is immobilized between the electrodes either by absorption in a microporous structure or in a gelled form. This standard defines the dimensions of the batteries in length, height and width as well as the shapes of the terminals. The lead-acid cells and batteries which are described in IEC 61056-2 should be tested according to the requirements of IEC 61056-1. The part of IEC 61056 does not apply for example to lead-acid cells and batteries used for vehicle engine starting applications (IEC 60095 series), traction applications (IEC 60254 series) or stationary applications (IEC 60896 series). Conformance to this standard requires that dimensions, terminals and marking shall correspond to these requirements.
