Battery

A
Warning!
Risk ofshort circuit andfire.

I>
Observe allwarning notesonthe battery.

I>
Disconnect thebattery duringallwork onthe
electrical system.

I>
Donot laytools orother metal objects onthe
battery asthey could cause ashort circuit
across thebattery terminal.

Hydrogen gasgenerated bythe battery
could cause anexplosion, resultinginsevere
personal injuries.

I>
Donot expose thebattery toan open flame,
electrical sparkoralit cigarette.

Risk ofsevere personal injuryanddamage to
the fabric, metalorpaint.

I>
Wear eyeprotection.

I>
Donot allow battery acidtocome incontact
with your skin, eyes, fabric orpainted surfac-

es.
I>

Ifyou getelectrolyte, whichisan acid, inyour
eyes oron your skin, immediately rinsewith
cold water forseveral minutes andcalladoc-
tor.

I>
Spilled electrolyte mustberinsed offatonce
with asolution ofbaking sodaandwater to
neutralize theacid.

Battery posts,terminals andrelated acces-
sories contain leadandlead compounds,
chemicals knowntothe State ofCalifornia to
cause cancer andreproductive harm.

I>
Always protect yourskinbywashing thorough-
ly with soap andwater.
Charge
state

A well charged batterywillnotonly prevent start-
ing problems butwill also lastlonger.

In order toavoid discharging thebattery
unintentionally:

I>
Curtail unnecessary powerconsumption, par-
ticularly incity traffic orwhen travelling short
distances only.

I>
Always remove theignition keywhen leaving
the car.
Practical Tips,Emergency Service

Battery care

I>
Ensure thatbattery issecurely mounted.

I>
Keep terminals andconnections cleanand
properly tightened.
Corrosion canbeprevented bycoating theter-
minals andconnections withpetroleum jellyor
silicone spray.

I>
Ensure thatvent caps aresecurely tightened
to prevent spillage.
Practical Tips,Emergency Service Checking
theelectrolyte fluidlevel
Generally, theelectrolyte levelmust bechecked
more ofteninsummer thaninthe winter, andmore
often when driving longdistances.

I>
When adding water,useonly clean vessels.
In no case mayalcohol (e.g.window cleaner
residues) bepermitted toenter thebattery.

I>
Unscrew andopen thefiller ventcaps ofeach
cell.
With thecarhorizontal, thefluid level should meet
the indicator markineach cell.

i>
Ifnecessary, topupwith distilled water.
Do not use acid.
Only fillup tothe mark, otherwise theelectro-
lyte willoverflow whenthebattery isbeing
charged andcause damage. Battery
charging
Automotive batteriesloosetheirefficiency when
not inuse.
The charge available inyour battery canbemea-
sured withabattery hydrometer.
We recommend thatthebattery voltage betested
by your Porsche dealerwhohastheappropriate
equipment.
If the car isnot driven forprolonged periods,the
battery mustbecharged atleast every 6weeks.
A discharged batteryallowsrapidformation ofsul-
fates, leading topremature deterioration ofthe
plates.

j!\
Warning!
Hydrogen gasgenerated bythe battery
could cause anexplosion, resultinginsevere
personal injuries.

c> Charge battery inawell ventilated area.
c> Never charge afrozen battery. Itmay explode
because ofgas trapped inthe ice. Allow afro-
zen battery tothaw outfirst.
c> Ifyou getelectrolyte, whichisan acid, inyour
eyes oron your skin, immediately rinsewith
cold water forseveral minutes andcalladoc-
tor.

ing, andtheheadlights, heater,rearwindow de-
fogger, etc.,areused more frequently.
c> let your Porsche dealertestthebattery's
capacity beforewintersetsin.

the car has been parked foralong time, thebat-
tery ofanother carcan beused forstarting with
the help ofjumper cables.
Make surethevoltage ofboth batteries isthe
same.
The capacity (Ampere hours,Ah)ofthe booster
battery mustnotbesubstantially lessthan thatof
the discharged battery.
The discharged batterymustbecorrectly con-
nected tothe vehicle's electrical system.
