The following specifications are common to all vehicle batteries, not only for the batteries of this standard.

4.2 Marking
4.2.1 Safety labelling

The batteries shall bear the six coloured safety symbols in accordance with EN 50342-1.

4.2.2 Marking of the polarity of terminals
4.2.2.1 General

The batteries shall be marked with signs for both polarities that have to be positioned near to or on the top face

of the terminals.
4.2.2.2 Marking of positive terminals

This marking shall take the form of the symbol “+” either on the upper surface of the positive terminal or on the

lid adjacent to the positive terminal.

4.2.2.3 Marking of negative terminals

This marking shall take the form of the symbol “–“ either on the upper surface of the negative terminal or on the

lid adjacent to the negative terminal.
4.2.2.4 Design and dimensions of marking of terminals

The symbols used for marking the terminals shall be in accordance with the IEC 60417, symbol 5005 for the

positive and symbol 5006 for the negative polarity.
The dimensions of the marking shall be according to Figure 1.
Dimensions in millimetres
Figure 1 — Marking of polarity
The polarity symbols may be either indented or embossed by (0,4 ± 0,1) mm.
4.3 Recycling
4.3.1 Recycling of lead

The batteries shall be marked with the symbols for recycling and separate collection in accordance with

EN 61429 as it relates to European Directives.
4.3.2 Recycling of plastic material

Injection moulded battery components need to be marked according to ISO 11469 and ISO 1043-1. The

marking shall be placed on the bottom of the battery container or on one short side near the ledge.

According to ISO 11469 and ISO 1043-1, the minimum marking for polypropylene-polyethylene copolymer

is > PP < or > PP/PE < .

In addition it is possible to show the recycling symbol with number 7 (Unicode Character 'RECYCLING SYMBOL

FOR TYPE-7 PLASTICS' (U+2679) according to ISO/IEC 10646) and the term “Other”.

The recommended thickness is (0,3 ± 0,1) mm. The height of the marking characters shall be between 5 mm

and 7 mm.
An example for this marking is shown in Figure 2.

4.4 Dimensions and design
All dimensions in this document are given in millimetres.

All dimensions given in this document correspond to a temperature of 20 °C of the polypropylene-polyethylene

copolymer.

Details of the design that are not indicated in the generic drawings need to be chosen appropriately.

The generic drawings in this standard are possible examples only. Especially the design of the lid, handles, ribs,

ledges and vent caps are not mandatory in total.
5 Recommended types
5.1 General
For new battery developments, only the recommended series shall be used.
This clause specifies:
– the main dimensions of starter batteries of the preferred LN series;

– the location of the positive and negative terminals with respect to the fastening system;

– the dimensions of tapered terminals of starter batteries;
5.2 Main dimensions of batteries

The main dimensions of the batteries of the LN series are shown in Table 1 and Figure 3, Figure 4, Figure 5

and Figure 6.
NOTE The schematic drawings do not show every design detail of the battery.
