can be cracked due to ice format ion and can leak
battery acid.
Battery charging (Maximum charging rate of
30 amps/ 14.8 Volt)
When charging at
low voltages (e.g. with a trick­
le charger), the battery cables do not have to be
d isconnected first. The battery caps should
not
be opened when charging a battery.
It is not necessary to remove the battery from
the luggage compartment, and it is also not nec­
essary to disconnect the cables.
Fast charging the battery (charging rate
above 14.8 Volts)
F or technical reasons do not use a battery charg­
er 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.
-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 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 generat­
ed by the battery is exp losive.
- To reduce the danger of explosion, never
connect or disconnect charger cables wh ile
the charger is operat ing.
- 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.
Checking and Filling
(D Note
Never use a fast charger as a booster to start
the engine. This will seriously damage sensi­
tive electronic components, such as control units, relays, radio, etc., as well as the battery
charger.
Battery replacement
The new battery must hove the some specifica­
tions and dimensions as the original equipment
battery.
Intelligent energy management in your vehicle is
responsible for distribut ing the e lectrical energy
throughout your vehicle
c;, page 121 . The intelli ­
gent energy management system will keep the
engine battery charged better than vehicles with­
out this system. To make sure the additional
electrical energy 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
t ime your vehicle was delivered). Specifications
are listed on the battery housing . Your author­
ized dealer must code the battery in the energy
management system to enable you to use the en­
ergy management functions correctly after re­
plac ing the battery.
The new battery must have the same capacity,
voltage (12-volts), amperage, construction and plug seal ing.
When install ing the battery, make sure the ign i­
t ion and all electr ical consumers are switched
off .
(D Note
Make sure the venti lation hose on the s ide of
the battery is connected, otherwise fumes or battery acid can leak out .
@ For the sake of the environment
Because of the problem of proper d isposal of
a battery, we recommend your authorized
Audi dealer change the battery for you. Bat­
teries contain sulfur ic acid and lead and must
always be disposed of properly in compliance .,.
