Checking the electrolyte
fluid
level
The electrolyte
fluid level
in your battery
can
be checked
by
unscrewing
and
opening the
filler and vent
caps
of
each cell.
The
fluid
level should meet the
indicator mark
in
each
cell. lf
necessary,
top up
with distilled water.
How often
water must be
added depends
on
operating conditions and
on
the time
of year.
Generally,
the
electrolyte
level must
be
checked more often
in
summer
than
in
the
winter, and more often when driving long dis-
tances.
Only top up
to
mark, otherwise the
electrolyte
will
overflow
when
the
battery
is
being
charged and cause
damage.
Car
battery
.
Battery
should be
securely mounted.
.
Terminals
and
connections should
be
kept
clean and properly tightened.
Corrosion can
be prevented by coating terminals and
con-
nections
with petroleum
jelly or
silicone
spray.
.
Vent
caps must
be securely
tightened to
prevent spillage.
Winter operation
During
the winter
months, battery
capacity
tends
to
decrease as temperatures drop.
Ad-
ditionally,
more power
is
consumed while
starting, and
the
headlights, heater, rear
win-
100
dow defogger, etc., are used more frequently.
Curtail unnecessary power consurnption, par-
ticularly
in city
traffic
or when travellrng short
distances
only. Let your
Porsche dealer test
the
battery's capacity before winter sets in.
A
well charged battery
will
not only
prevent
starting
problems but
will also live longer'
Battery
charging
Automotive
batteries loose
their
eff
iciency
when not in
use.
The charge available
in your
battery
can be measured
with
a
hydrometer'
We recommend
that battery voltage be tested
by your
Porsche dealer
who has
the
appro-
priate equipment.
lf
the car
is
not
drlven
for
prolonged periods,
the
battery
must
be
charged
at
least every 6 weeks. A
discharged
battery allows rapid formation
of
sulJates,
leading
to
premature deterioration
of
the
plates.
lf you get

spark.
Do not
smoke. HYdrogen gas
generated
by
the battery is explosive'
.
Electrolyte
fluid
that may spill
during
charging should be wâshed off
with a
so-
lution of warm
water and
baking soda
to
neutralize
the acid.
