Charging the battery
Automotive batteries lose their efficiency when
not in use. The charge available in your battery can
be measured with a battery hydrometer. We
recommend that the battery voltage be tested by
your authorized Porsche dealer who has the
appropriate equipment.
If the car is not driven for prolonged periods, the
battery must be charged at least every 6 weeks.
A discharged battery allows rapid formation of
sulfates, leading to premature deterioration of the
plates.
f
Charge battery in a well ventilated area due to
hydrogen gas explosion risk.
f
Never charge a frozen battery. It may explode
because of gas trapped in the ice. Allow a
frozen battery to thaw out first.
f
If you get electrolyte, which is an acid, in your
eyes or on your skin, immediately rinse with
cold water for several minutes.
Your authorized Porsche dealer will be pleased to
advise you about a suitable charger.
f
Always observe the instructions provided by
the charger manufacturer.
f
If the battery is frozen, thaw it out first before
charging it.
f
When charging the battery, ensure adequate
ventilation.
1.
Connect the charger to the emergency starting
terminals.
Only plug into the mains and switch the
charger on when it is connected up correctly.
2.
Switch on the charger.
3.
After charging the battery, first switch off the
charger and then disconnect it.
