246 Checking and filling
-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.
- 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.
(D 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
¢ page 204. The intelligent energy manage­
ment system will keep the engine battery
charged better than vehicles without this sys­
tem. To make sure the additional elec trical 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.
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, other­
wise 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.
- Battery mounts and clamps must always
be secured correctly.
- Read and follow the warnings under
¢ page 243, Working on the battery be­
fore performing any work on the 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 .
