Checking the electrolyte fluid level
The acid level should be checked more frequently by a qualified specialist workshop during the summer months and in predominantly warm countries.
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.
Battery Explosion Hazard
Eye or Skin Contact
Slow battery charging
Your authorized Porsche dealer will be pleased to advise you about a suitable charger.
The capacity and ability of the battery to store power decreases at low outside temperatures.
Moreover, the battery is more heavily loaded in winter months, e.g. by the heated rear window, more frequent use of additional lights, the fans and the windshield wipers, etc.
Keep the battery well charged to prevent it from freezing.
A discharged battery can freeze at 23 °F (--5 °C), but a fully charged battery only freezes at -- 40 °F (--40 °C).
A frozen battery must always be thawed before connecting jump leads.
The service life of the battery is subject to normal wear; it depends greatly on care, climatic conditions, and driving conditions (distances, loads).
