This European Standard is applicable to lead-acid batteries used for starting, lighting and ignition of
passenger automobiles and light commercial vehicles with a nominal voltage of 36 V. This standard specifies
the position, details of design and dimensions of a system of battery terminals.
Starter batteries with 36 V nominal voltage may have the same dimensions and means for fixation as 6 V or
12 V batteries. This can be either intentional or unintentional. Therefore, the compatibility of batteries with
36 V nominal voltage down to electric power nets with 6 V or 12 V nominal voltage should be prevented.
Such design of a 36 V termination and contacting system must prevent the case to be connected to a 6 V or
12 V power net in order to avoid serious damage in the 6 V or 12 V power net. For the same reason the
design of the battery terminals must prevent that standard commercial jumper-cables may be contacted to
the 36 V battery terminals if the battery is installed in the vehicle or not.
A commercial application of this standard must expressively be agreed upon as the final standard may differ
from the present draft.
