- Charge the battery in a well ventilated
area. Keep away from open flame or elec-
trical spark. Do not smoke. Hydrogen gas
generated by the battery is explosive.
- To reduce the danger of explosion, never
connect or disconnect charger cables
while the charger is operating.
- Fast charging a battery is dangerous and
should only be attempted
by a compe-
tent technician with the proper equip-
ment.
- Battery acid that may spill during charg-
ing should be washed off with a solution
of warm water and baking soda to neu-
tralize the acid.

Note
Never use a fast charger as a booster to
start the engine. This will seriously dam-
age sensitive electronic components, such
as control units, relays, radio, etc., as well
as the battery charger.
Battery replacement
The new battery must have the same specifi-
cations and dimensions as the original equip-
ment battery.
Intelligent energy management
in your vehi-
cle is responsible for distributing the electri-
cal energy throughout your vehicle
q page 198.
The intelligent energy manage-
ment system will keep the engine battery
charged better than vehicles without this sys-
tem. To make sure the additional electrical en-
ergy is available once again after you have
changed the battery, we recommend that you
install batteries of the same type and manu -
facture only (the same as those installed at
the time your vehicle was delivered). Specifi-
cations are listed on the battery housing. Your
authorized dealer must code the battery in
the energy management
system to enable you
to use the energy management
functions cor-
rectly after replacing the battery.
Checking
and filling
235
The new battery must have the same capacity,
voltage (12-volts), amperage, construction
and plug sealing.
When installing the battery, make sure the ig-
nition and all electrical consumers are switch-
ed off.
(D
Note
Make sure the ventilation hose on the side
of the battery is connected, otherwise
fumes or battery acid can leak out.
- Vehicles with the Start-Stop-System*
are
equipped with a special cycle-proof AGM
battery. Installing a different type of
battery can cause problems in the vehi-
cle electrical system. When replacing the
vehicle battery, always install one with
the same specifications as the original
battery.

For the sake of the environment
Because of the problem of proper disposal
of a battery, we recommend your author-
ized Audi dealer change the battery for
you. Batteries contain sulfuric acid and
lead and must always be disposed of prop-
erly in compliance with all environmental
regulations. Disposing of vehicle batteries
improperly is very dangerous to the envi-
ronment.
