A discharged battery can freeze at temperatures
of only 32 °F (0 °C). Allow a frozen battery to
thaw completely before attempting to charge it
9 & . However, we recommend not using a
thawed battery again because the batte ry casing
can be cracked due to ice formation and can leak
battery ac id.
Battery charg ing (Ma ximum charging rate of
30 amps /14.8 Volt )
When charging at low voltages (e.g. w ith a tri ckl e
c h arge r),
the battery cables do not have to be
disconnected first. The battery caps shou ld
not
be opened when charging a battery.
It is not necessary to remove the batte ry from
the luggage compartment.
F a st charging th e battery (charg ing r ate
above 14.8 Vo lts )
For technical reasons do no t use a battery charg
e r that uses voltage greater than 14.8 Volts to
charge your vehicle's battery .
A WARNING
Charging a battery can be dangerous.
- Always follow the operating instructions
provided by the battery charger manufactur
er when charging your battery.
Checking and Fillin g
-Never charge a frozen battery. It may ex
plode because of gas trapped in the ice. Al
low a frozen battery to thaw out first.
- Do not reuse batteries wh ich were frozen.
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 electrical
spark. Do not smoke. Hydrogen gas generat
ed by the batte ry is explosive.
- To reduce the danger of explosion, never
connect or d isconnect charger cables wh ile
the charger is operating.
- Fast charging a battery is dangerous and
should only be attempted by a competent
technician w ith the proper equipment.
- Battery acid that may sp ill dur ing charging
should be washed
off with a solut ion of
warm water and baking soda to neutralize the acid .
@ Note
Never use a fast charger as a booster to start
the engine . This w ill ser iously damage sensi
tive electronic components, suc h as control
units, relays, radio, etc., as we ll as the battery
charger.
Battery replacement
The new battery must have the same specifica
tions and dimensions as the original equipment
battery.
Intelligent energy management in your vehicle is
responsible for distributing the elect rical energy
throughout your vehicle
9 page 175. T he intelli
gent energy management system w ill keep the
engine battery charged better then vehicles with
out this system. To make sure the additional elec
trical energy is avai lab le 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
t ime your vehicle was delivered) . Specifications
are listed on the battery housing . Your autho r
ized Audi dealer must code the battery in the en-
ergy management system to enab le you to use .,,.
