Visual check of battery

A visual check of the battery should be performed before executing measurements such as open-circuit voltage, electrolyte density or battery load check.

• Check the following:

• Is the battery housing damaged? Damage to the casing can allow acid to escape from the battery.
• Are the battery terminals (battery connections) damaged? Because of a damaged battery terminal, contact of the wiring connections is not ensured. This can cause a cable fire and interfere with the function of the electrical system.
• Are the original battery sealing plugs installed? The sealing plugs must be equipped with an O-ring seal. In case of loss or damage, only original sealing plugs of the same type may be used.
