Portable lead-acid cells and batteries (Valve regulated types)- Part 2: Dimensions, terminals and marking

Document Number: NL IEC 61056 2 : 2005
Sector: Electrical Engineering
TC: NL TC IRI
ICS: 29.220.20
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 instance, 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 this standard should be tested according to the requirements of IEC 61056-1. This 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 correspond to these requirements.
