Visual Inspection

WARNING: This page is about a different car, the 2010 Porsche Cayenne, 2009 Porsche Cayenne, and 2008 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.

A visual inspection of the battery must be performed before taking measurements, e.g. measuring the open-circuit voltage, or before carrying out the battery load test.

This inspection can be used to determine:

Whether the housing of the battery is damaged. The leak-free operation and function of the battery cannot be guaranteed if the housing is damaged.
Whether the battery terminals (battery line connections) are damaged. Contact of the line connections cannot be guaranteed if the battery terminals are damaged. This can cause a line fire and malfunctions in the electrical system.
