When it comes to generating electrical power, alternators found in most cars and boats follow the same working principle of transforming the mechanical energy of rotation into electric current. Their main parts are also quite similar: a series of windings known as a stator, rotor, brushes, bearings, and some other components; some boaters even search for a more affordable automotive alternator instead of a specialized marine one. In many cases, such a replacement works, but there are still certain factors to consider when it comes to a marine alternator, and it's better to make an informed choice.
One of these factors is the ability of the alternator to provide specified amperage for a long time without overheating. An automotive battery is relatively small and needs less time to charge, while its marine counterparts often unite in battery banks, apart from the starter battery. Capable of continuous operation, marine alts use more intelligent, smooth methods of charging all the batteries to prolong their lifespan. Besides, many of them utilize spark screens, improved insulation, and better corrosion protection than automotive alternators. Our online store offers a wide range of marine alternators that meet all the necessary requirements and are crafted by leading companies such as Arco, Balmar, and others.
