2015 AUDI S3 battery

230 Checking and Filling
-Do not expose the battery to an open
flame, electric sparks or an open light.
- Do not smoke.
- Do not interchange the positive and neg-
ative cables.
- When working on the battery, be sure
not to short-circuit the terminals with
tools or other metal objects. This would
cause the battery to heat up very quickly,
which could lead to damage or explosion
and personal injury.
- When a battery is charged, it produces
hydrogen gas which is explosive and
could cause personal injury.
- Always keep the battery well out of the
reach of children.
- Before work is done on the electrical sys­
tem, disconnect the negative ground ca­ ble.
- Before performing any work on the elec­
trical system, switch off the engine and ignition as well as any electrical equip ­
ment . The negative cable on the battery
must be disconnected . If you are just go­
ing to replace a light bulb, then it is
enough to switch off the lights.
- Before disconnecting the battery, switch
off the anti-theft alarm system! Other­
wise you will set off the alarm.
- When disconnecting the battery, first
disconnect the negative cable and then
the positive cable .
- Before reconnecting the battery, make
sure all electrical consumers are switch­
ed off. Reconnect the positive cable first
and then the negative cable. Never inter­
change the cables -this could start a fire!
- Never charge a frozen or a thawed-out
battery. It could explode! If a battery has
frozen, then it must be replaced. A dead battery can free ze over at 32°F (O°C).
- Make sure the vent hose is always attach­
ed to the opening on the side of the bat­
tery.
- Never use batteries which are damaged.
There is the danger of an explosion! Al­
ways replace a damaged battery . A WARNING
-California Proposition 65 Warning:
- Battery posts, terminals and related ac­
cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive problems . Wash hands after han­
dling.
(D Note
- Do not disconnect the vehicle battery
when the ignition is on or when the en ­
gine is running, otherwise, you will dam­
age electronic components in the electri­
cal system.
- If your vehicle is going to stand for a
long period of time without being driven,
protect the battery from "freezing", oth­
erwise it will be damaged and will then
have to be replaced.
Battery charging
Starting the engine requires a well charged
battery.

A discharged battery can freeze at tempera­
tures of on ly 32 F
0 (0 °C). A llow a frozen bat­
tery to thaw completely before attempt ing to
charge it
c:> &. . However, we recommend not
using a thawed battery again because the bat­
tery cas ing can be cracked due to ice forma­
tion and can leak battery acid.
B atter y ch arging (Ma ximum charging rate
of
30 amps / 14.8 Volt)
When cha rging at low voltages (e .g. w ith a
tric kle charger ), the battery cables do not
have to be d isconnected first. The batte ry
caps sho uld
not be opened when charging a
battery .
It is not necessary to remove the batte ry from
the luggage compa rtment, and it is also not
necessa ry to disconnec t the cables.
Fa st charging the b attery (charging rate
above
14.8 Volts )
For technica l reasons do not use a battery
charger that uses voltage g reate r than
14.8 Volts to charge your veh icle's battery.
WARNING
Charging a battery can be dangerous.
- Always fo llow the oper ating instructions
provided by the battery charge r manu­
fact urer when charging your battery.
Checking and Fillin g 231
-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 wh ich 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 explos ive.
- To reduce the danger of explosion, never connect or d isconnect charger cab les
while the charger is ope rat ing.
- Fast charging a batte ry is dangerous and
should only be attempted by a compe­
tent techn ic ian with the prope r equip­
ment.
- Battery acid that may spi ll dur ing cha rg­
ing should be washed off wi th a solut io n
of wa rm w ater and baking soda to neu­
trali ze the ac id.
(D Note
Neve r use a fast cha rger as a boost er to
star t the engine. This w ill ser iously dam­
age sens it ive e lectronic componen ts, su ch
as cont ro l units, re lays, 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.
Inte lligent energy management in your vehi­
cl e is responsible for dist ributing the elect ri­
ca l energy throughout yo ur vehicle
<=> page 194 . The intelligent energy manage­
ment system will keep the engine battery
charged better than vehicles without this sys­
tem . To make sure the additional electrical en­
ergy is ava ilab le once again after you have
changed the batte ry, we recommend that you
insta ll batteries of the same type and manu-
factu re on ly (the same as those installed at
IJI,,
•
•
•

232 Check ing and F illin g
the time your vehicle was delivered) . Specifi­
cations are listed on the battery housing. Yo ur
author ized dealer must code the battery in
the energy management system to enable you
to use the energy management functions cor­ rectly after replac ing the battery .
The new battery must have the same capacity,
voltage (12-volts), amperage, construct ion
and plug sealing.
When insta lling the battery, make sure the ig­
n ition and all e lectr ica l consumers are sw itch­
ed off.
Make sure the venti lation hose on the side
of the battery is connected, otherwise
fumes or battery ac id can leak out.
@ For the sake of the environment
Because of the problem of proper disposa l
of a battery, we recommend your author­
ized Audi dealer change the battery for
you. Batter ies contain su lfuric ac id and
lead and must always be disposed of prop ­
erly i n compliance w ith all environmental
regu lations . D ispos ing of vehicle batteries
improper ly is very dangerous to t he envi­
ronmen t.
