Visual Inspection

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

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.
