Practical Tips, Emergency Service
Charge stateA well-charged battery prevents starting problems
and has a longer useful life.
Traffic density, speed limits, requirements
regarding noise, exhaust gas and fuel consump-
tion reduce the engine speed and, hence, the
generator output.
However, the large number of electrical loads has
markedly increased the demand for electrical
power.
In order to avoid unintended battery
discharge
fSwitch off unnecessary electrical loads in city
traffic, on short trips and in queues.
fAlways withdraw the ignition key when leaving
the vehicle.
fAvoid frequent operation of the convertible top
and operation of the Porsche Communication
Management system when the engine is not
running.
Battery carefKeep battery surface clean and dry.
fEnsure that cell plugs and terminal clamps are
firmly secured.
Checking acid level
The acid level should be more frequently checked
by a qualified specialist workshop during the
summer months and in predominantly warm
countries.
Charging the battery
Your Porsche partner will be pleased to advise you
about a suitable charger.
1. Always observe the instructions of the charger
manufacturer.
Depending on the type of charger, the battery
may have to be disconnected. Extremely
important: disconnect the negative cable first,
and then the positive cable – danger of short
circuit!
Reconnection must be carried out in reverse
order.
2. Before charging, cold batteries must be
warmed up indoors.
3. Frozen batteries must not be charged. They
must be replaced with a new battery.
4. When charging, ensure adequate ventilation. 5. Connect charger to the battery.
Only plug into the mains and switch the
charger on when it has been correctly
connected up.
Warning!
Hydrogen gas generated by the battery
could cause an explosion, resulting in severe
personal injuries.
fCharge battery in a well ventilated area.
fNever charge a frozen battery. It may explode
because of gas trapped in the ice. Allow a fro-
zen battery to thaw out first.
fIf you get electrolyte, which is an acid, in your
eyes or on your skin, immediately rinse with
cold water for several minutes and call a doc-tor.
