A well-charged battery prevents starting problems and has a longer service life.
In order to avoid unintentional battery discharge:
Switch off unnecessary electrical loads in city traffic, on short trips or in a line of traffic.
Always remove the ignition key when leaving the vehicle or
switch off the ignition on vehicles with Porsche Entry & Drive.
Avoid using the Porsche Communication Management system and the audio system when the engine is not running.
Please see the chapter "CHARGING THE BATTERY" on page 320.
Information In the cold season in particular or if the vehicle is used primarily for short distances, it may be necessary to recharge the battery from time to time.
Ensure that battery is securely mounted.
Keep battery surface clean and dry.
Keep terminals and connections clean. Corrosion can be prevented by coating the terminals and connections with petroleum jelly or silicone spray.
Ensure that terminal clamps and the vent hose are firmly secured.
The ability of the battery to deliver and store
power decreases at low outside temperatures.
Moreover, the battery is more heavily loaded in the
winter months, e.g. by the heated rear window,
the more frequent use of additional lights,
the blower and the windshield wipers, etc.
Have the battery checked at your authorized
Porsche dealer before winter begins.
Information Keep the battery fully charged to prevent it from freezing.
A flat battery can freeze even at 23 °F (–5 °C), but a fully charged one only freezes at -40 °F (–40 °C).
If the battery is frozen, thaw it out before connecting jumper cables.
If the vehicle is left for long periods in the garage or workshop, the doors and lids should be closed.
Remove the ignition key and, if necessary,
disconnect the battery or, on vehicles with
Porsche Entry & Drive, switch off the ignition.
When the battery is disconnected, the alarm system ceases to function.
If the vehicle was locked before the battery
was disconnected, the alarm will be triggered
when the battery is reconnected.
To deactivate the alarm system:
Lock the vehicle and unlock it again.
Alarm system, central locking
The status of the central locking and alarm system does not change when you disconnect the battery.
Information Even if you put your vehicle out of operation, the battery still discharges.
The battery must be charged, i.e. connected to a charger, approximately every 6 weeks in order to preserve battery function.
Store a battery that has been removed in a dark, cool place that is not exposed to frost.
Replacing the battery
The battery is subject to normal wear: its service
life depends heavily on the care you give it,
climatic conditions and the conditions of use
It is not possible to use the details on the battery
case to determine a comparable battery that
meets all the specific requirements of Porsche.
Have the battery removed and installed only by your authorized Porsche dealer.
Only use an original Porsche battery, with the
correct part number, as a replacement. Only
this battery meets the specific requirements of
After you install a new battery, it must be initialised in the control unit.
Please contact your authorized Porsche dealer.
Please observe the disposal instructions for batteries.
