f
Do not lean over the battery due to danger of
chemical burns from leaking acid.
f
Improper use of booster battery to start a
vehicle may cause an explosion.
f
Keep sources of ignition away from the
battery, e.g. naked flame, burning cigarettes
or sparks due to cable contact.
f
Before connecting jumper cables, it is
essential to thaw out a frozen battery.
External power supply/emergency
starting with jumper cables
Always observe the sequence below:
1.
Open the cap on the positive terminal for jump
starting (
+
).
2.
Attach the positive lead first to the positive
terminal for jump starting (
+
), then to the
positive terminal of the donor battery.
3.
Connect the negative lead first to the negative
terminal of the donor battery, then to the
ground point for jump starting (
–
).

4.
Leave the engine of the donor vehicle running
at a higher engine speed.
5.
Start the engine.
An attempted start using jumper cables should
not last more than 15 seconds. Then wait for
at least one minute.
6.
Disconnect the negative jumper cable from the
ground point for jump starting (
–
) first, then
from the negative terminal of the donor
battery.
7.
Disconnect the positive jumper cable from the
positive terminal of the donor battery first,
then from the positive terminal for jump
starting (
+
).
8.
Close the cap on the positive terminal for jump
starting (
+
).
Charging the battery
Automotive batteries loose 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.
