AGM Battery Care and Maintenance: From Vehicle Delivery Until Sale (customer handover)
(67/12)
Vehicle Type:
Cayenne (92A)/Cayenne S (92A)/Cayenne GTS (92A)/Cayenne Turbo (92A)
Model Year:
As of 2011
Concerns:
AGM starter battery (referred to below simply as 'battery')
Situation:
Support for the care and maintenance of the AGM starter battery (at the dealership):
From the time the vehicle is delivered to the Porsche Centre until it is handed over to the
customer, the battery must be maintained and charged regularly, depending on use.
Information
The battery has a limited service life.
The service life of the battery is affected by:
- the driving conditions for the vehicle and
- thus, by the care and maintenance of the battery (trickle charging, etc.).
 If a charger is not connected in order to trickle-charge the battery when the vehicle is idle for extended
periods,
the battery life will be reduced considerably, thereby resulting in natural wear.
Please pass this information on to your customers.
Tools:
9818 - PIWIS Tester II
