A discharged battery can freeze at temperatures of only O °C. Allow
a frozen battery to thaw completely before attempting to charge it
~ & .However, we recommend not using a thawed battery again
because the battery casing can be cracked due to ice formation and
can leak battery acid.
Battery charging (Maximum charging rate of 30
amps/14.8 Volt)
When charging at /ow voltages (e.g. with a trickle charger), the
battery cables do not have to be disconnected first. The battery caps
should
not be opened when charging a battery.
It is not necessary to remove the battery from the luggage compart ­
ment.
Fast charging the battery (charging rate above 14 .8
Volts)
For technical reasons do not use a battery charger that uses voltage
greater than 14.8 Volts to charge your vehicle's battery.
& WARNING
Charging a battery can be dangerous.
• Always follow the operating instructions provided by the
battery charger manufacturer when charging your battery.
• Never charge a frozen battery. It may explode because of gas
trapped in the ice. Allow a frozen battery to thaw out first.
• Do not reuse batteries which 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 gener­
ated 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 competent technician with the proper equipment.
• Battery acid that may spill during charging should be washed
off with a solution of warm water and baking soda to neutralize
the acid .
0 Note
Never use a fast charger as a booster to start the engine. This will
seriously damage 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 specffications and
dimensi ons as the original equipment battery.
Intel ligen t energy management in your vehicle is responsible for
distributing the e lectrica l ene rgy throughout your vehicle
::} page 295. The intelligent energy management system will keep
the engine battery charged bette r then vehicles wi thou t this system .
To make sure the additional electrical energy is available once again
after you have changed the batte ry, we recommend that you install
batteries of the same type and manufacture only (the same as those
installed at the time your vehicle was delivered). Specifications are
listed on the battery housing . Your authorized Audi dealer will then
code the battery management cont rol unit .
If i t is no t possib le to use a ba ttery o f this type, the new battery m ust
have the same capacity, vo ltage (12 volts), amperage, construction
and plug seal ing.
When installing the battery, make sure the ignition and all electrica l
consumers are turned off .
0 Note
Make sure the ventilation hose on the side of the bat tery is
connected, otherwise fumes or battery acid can leak out .
W For the sake of the environment
Because of the problem of proper d isposal of a battery , we recom­
mend your authorized Aud i dea ler change the battery for you .
Ba tteries contain sulfuric acid a nd lead and must always be
disposed of properly in compliance with all environmental regula ­
tions. D isposi ng o f vehicle ba tteries i mproper ly is very dangerous to
