~ Install the battery cover.
~ Close the luggage compartment lid
¢page 42.
When charging at low voltages (e.g. with a
trickle charger), the battery cables do not
have to be disconnected first. Before charging
at
high voltages, i.e. "fast charging", you
must disconnect both cables. In either case,
follow the instructions from the manufacturer
of the charger .
Fastcharging a battery is
dangerous ¢.&. in
Working on the battery on page 185 .
It re
quires special charging equipment and the knowledge to go with it. We recommend hav
ing your battery fast charged only by a quali
fied workshop.
A discharged battery can
freeze at tempera
tures of only 32 °F (0 °C) . Allow a frozen bat
tery to thaw completely before attempting to
charge it¢ ,&. . However, we recommend not
using a thawed battery again because the bat
tery casing can be cracked due to ice forma
tion and can leak battery acid.
Do not open the battery caps when charging
the battery.
_& WARNING
-
Charging a battery can be dangerous.
- Never charge a frozen battery .
It may ex
plode because of gas trapped in the ice.
Allow a frozen battery to thaw out first.
- Do not reuse batteries which were fro
zen. The battery housing may have
cracked and weakened when the battery
froze.
- 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.
Checking and filling 187
- 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 .
(D Tips
-The vehicle battery must not be charged
with a standard small charger that plugs
into the cigarette lighter or outlet .
- Only charge the battery through the con
nections in the luggage compartment.
Replacing the battery
The new battery must have the same specifi
cations as the old one.
Your vehicle is equipped with an intelligent
energy management system for distributing
electricity ¢
page 155. The battery charges
better in vehicles with the energy manage
ment system than in vehicles without the sys
tem. To ensure that the additional power is
available after replacing the battery , replacing
with the same type of battery from the same
manufacturer (like the battery that was deliv
ered with the vehicle) is recommended. An au
thori zed dealer mus t code the battery in the
energy management control module .
T he new battery must have the same capacity,
voltage (12 volts), current and design and it
must be sealed with plugs. The battery must
conform to the standards TL 825 06 (from Oc
tober 2006) and VW 7 50 73 (from August 2001).
Since the vehicle battery is difficult to reach,
we recommend having the battery replaced by
an authorized Audi R8 dealer or other quali-
fied workshop . ..,. •
