Introduction to the topic
The 12-
volt vehicle battery is a component of
the electrical system and in event of the
high-voltage system failing, supplies the
safety-relevant systems of the vehicle with
energy. In the scope of maintenance work,
the 12-volt vehicle battery is checked and
where required, replaced.
You should only carry out work on the electri-
cal system if you know exactly how to per-
form the required tasks, are aware of the
general safety procedures and have access to
the correct equipment, service fluids and
suitable tools. Failing to carry out work cor-
rectly can cause serious injuries

Replacing the 12-volt vehicle battery
The 12-
volt vehicle battery has been devel-
oped to suit the conditions of its installation
location and has special safety features. If
a 12-volt vehicle battery has to be replaced,
discuss the electromagnetic compatibility,
size and necessary servicing, output and safe-
ty requirements for the new 12-volt vehicle
battery with a Volkswagen dealership before
purchase. The ventilation opening of the 12-
volt vehicle battery must always be on the
negative terminal side: the ventilation open-
ing on the positive terminal side must always
be sealed.
Only maintenance-free 12-volt vehicle bat-
teries compliant with the standards
TL 825 06 and VW 7 50 73 should be used.
These standards must be dated October 2014
or later.
Always have the 12-volt vehicle battery re-
placed by a qualified workshop, as the vehicle
electronics must be adapted as part of the
replacement process. Only qualified work-
shops have the technology required to carry
out this adjustment correctly. Volkswagen
recommends that the 12-volt vehicle battery
is replaced by a Volkswagen dealership.
Disconnecting the 12-volt vehicle battery
Please observe the following if the 12-volt
vehicle battery has to be disconnected from
the electrical system in the vehicle:
