Mastervolt Type D, 457N3V14 black

A proper cover and isolation of the battery poles prevents sparks or short circuiting, even in the toughest conditions. Mastervolt isolation covers protect the battery terminals completely, for your convenience and safety.Battery terminals are a problem in many applications, because dangerous vapours from battery acid cause corrosion on the lead surfaces and copper wiring associated with the battery wires. The same happens with environmental influences like rain. This acidic corrosion on surfacing and wiring should be cleaned periodically.However, prevention is better than cure. Therefore Mastervolt recommends the use of isolation covers.
