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.
