Information
The battery will run down even if the vehicle is out of
operation.
e To maintain its function, charge the battery ap-
proximately every 6 weeks or connect it to a
trickle charger suitable for lithium batteries with
a CC/CV or pure CV characteristic. Porsche rec-
ommends the charger and charge maintenance
unit from Porsche Tequipment.
Charging the battery
Escaping irritating gases
CAUTION
due to a damaged
battery
The use of boosters or non-approved chargers can
result in the battery being charged with excessively
high charging voltage and excessively high charging
current. This can damage the battery and irritating
gases can escape. This can cause considerable
damage to the vehicle and chemical burns.
e Do not use boosters.
e Only use chargers that have been approved by
the equipment manufacturer for LiFePO
teries with integrated electronic protection
circuits.
e The following maximum values must never be
exceeded:
– Max. charging voltage: 14.8 V (even in the
event of a fault with battery disconnected; no
voltage peaks permitted)
– Max. charging current: 90 A
e If in doubt, contact an authorized Porsche dealer.

Replacing the battery
WARNING
In addition to significant malfunctions of the vehicle
electrical system, use of an unsuitable lithium bat-
tery or its incorrect installation may, in exceptional
cases cause a fire (e.g. during charging).
e Never attempt to replace the battery yourself.
Only have the lithium battery of this vehicle re-
placed with a lithium battery explicitly intended
by Porsche for this vehicle. The use of other lith-
ium or lead-acid batteries results in significant
malfunctions including total failure of the elec-
trical system.
e Always have the battery replaced by an author-
ized Porsche dealer. Porsche recommends an
authorized Porsche dealer, as they have trained
