5.3 Handles
5.3.1 General
Batteries with a weight less than or equal to 20 kg may be designed without, with one, or with two handles. Batteries with a weight of more than 20 kg shall have two handles.
5.3.2 Mounting of handles
If the batteries have handles, the handles shall be integrated in the lid (see Figure 4).
NOTE The handle design shown on all the pages of this document is for information only. It is left to the battery manufacturer to propose a design in accordance with this document with respect to overall dimensions.
5.4 Mounting of batteries
5.4.1 General
Starter batteries in accordance with the LN series may be fixed to the vehicles either:
— by a bottom hold-down device of the long side,
— by a bottom hold-down device of the short side, or
— by means of a hold-down device engaging with the upper part of the battery (for example, a metal frame), connected to the top clamping area (see Figure 4 and Figure 7).
In either case, these batteries shall have top clamping areas on the long sides.
The hold-down clamps of support shall match with the ledges and notches to provide secure fastening in all directions.
5.4.2 Dimensions and arrangement of ledges and notches
All batteries of the LN series shall have ledges for fastening over the length of all sides as an integral part of the battery container and allowing the battery to be fixed by means of the bottom of the container.
The positions and dimensions of ledges and notches shall be according to Figure 6 and Figure 7.
The profile of the ledges shall be in accordance with Figure 8 and Figure 9. The length of the ledges on the rear side of the battery shall be reduced by 20 mm from both ends compared to the one on the front side (see Figure 4).
The hold-down clamps of the support shall match with the ledges and the notches to provide secure fastening in either direction.
To allow a symmetrical rotation for fastening the opposite ledges contain an equal number of notches. To secure correct positioning of the battery on the support the ledges shall have 5 notches on the long sides and 3 notches on the short sides.
5.5 Terminals
5.5.1 Position of terminals
The position of positive and negative terminals shall be in accordance with Figure 4.
5.5.2 Dimensions of battery terminals
The dimensions of the tapered positive and negative terminal shall be according to Figure 3.
5.5.3 Marking of polarity
The polarity of the batteries of the LN series shall be marked twice in the area of the terminals (see Figure 4).
The symbol of the polarity and the dimension of the symbols shall be in accordance with 4.2.2.

5.6 Special features of the battery lid
5.6.1 General
Batteries of the LN series shall have the following details.
5.6.2 Semi bloc lid
Batteries of the LN series shall have a block lid which includes the terminals and the vent plugs so that they are not higher than the lid surface. A special feature of the semi bloc lid is the top clamping area (see Figure 4 and Figure 7).
5.6.3 Central degassing
Batteries of the LN series shall have a central degassing system with degassing outlets at one or both of the short sides (see Figure 7 and Figure 10).
The central degassing system shall be designed in such a way that charging gasses from all six cells can leave the battery via all available outlets. A separation of a subset of cells to one outlet is not permissible.
A minimum depth of 10 mm for the insertion of connection parts in the degassing outlet shall be provided.
Any connection parts shall be connected gas tight to the degassing outlet.BS IEC 60095-2 pdf download.
