2013 AUDI A7 Battery

24 4 Ch eck ing and filling
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, rad io, 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 veh i­
cle is respons ible for d istributing the electr i­
cal energy throughout your vehicle
c::> page 202. The intell igent energy manage­
ment system w ill keep the engine battery
cha rged bette r than vehicles w ithout t his sys­
tem. To make sure the additional e lectrica l en­
e rgy is availab le once again after you have
changed the battery, we recommend that you
install batteries of the same type and man u­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations are listed on the battery hous ing. Your
author ized dealer must code the battery in
the energy management system to enable you
to use the energy management funct ions cor­
rectly after replac ing the battery .
The new battery must have the same capacity ,
voltage (12-volts), amperage, const ruct ion
and p lug sealing.
When insta lling the battery, make sure the ig­
n ition and all e lectr ica l consumers are sw itch ­
ed off .
{[) Note
Make sure the venti lation hose on the s ide
of the battery is connected, ot herwise
fumes or battery ac id can leak out.
- Vehicles with the Start-Stop-System* are
equipped with a special cycle-proof AGM
batte ry. Insta lling a differe nt type of
batte ry can ca use p rob lems in the vehi­
cle elect rical system. When rep lacing the
vehicle bat tery, always ins ta ll one wi th the same specifica
tions as the o rigina l
battery .
~ For the sake of the env ironment
B ec ause o f th e p rob lem of p roper disposal
of a battery, we recommend your author­
ized Audi dealer change the battery fo r
you. Batteries contain sul fur ic acid and
l ead and must always be disposed of prop­
erly in compl iance with all environmental
regulations. Disposing of veh icle batter ies
i mproperly is very dange rous to the envi­
r onment.

280 Emergency situations
@ Tips
The discharged battery must be properly
connected to the vehicle's electrical sys­
tem. When jump starting or charging the
battery, never connect the negative
ground cable to the battery negative post
because the batte ry manager system must
be able to detect the battery 's state of
charge. Always connect the negative
ground cab le to the negative ground post
of the battery manager control unit.
Use of jumper cables
Make sure to connect the jumper cable
clamps in exactly the order described below!
