![]() These batteries have been designed for applications in which engine starting is their primary role. Often, your vessel’s engine OE manufacturer will specify the minimum rating required to ensure sufficient starting power.įor vessels with an outboard engine and minimal electrical consumers, the Yuasa Active Marine battery range should be your go-to choice. MCA can be a helpful guide to specifying the correct marine battery. While both a measurement of cranking amps, it is important to note that MCA and CCA are not the same. For comparison, a similar test to determine the Cold Cranking Amperage (CCA) of a vehicle battery is conducted at a much higher 18☌. This is due to the seasonal use nature of the applications marine batteries are designed for. Unlike CCA / A (EN), MCA is measured at a temperature of 0☌ as this is more relevant to marine use.įor the more technically minded, Marine Cranking Amps are determined using the SAE testing standard and are calculated at 0☌. It is the number of Amperes it can deliver for 30 seconds. Marine Cranking Amps determine the amount of cranking power the battery is able to provide to start the engine. Put simply, the higher MCA rating, the more powerful the battery. The starting specification of a marine battery can be identified by the amount of Marine Cranking Amps (MCA). Remember, while it may seem sensible to simply fit the most powerful battery available, this can have a negative impact on overall weight. However, the most important factor is choosing a battery that meets the starting and auxiliary demands on your vessel. ![]() Whether traditional lead acid or EFB, any battery will bring significant weight. Weight is an important consideration, especially when choosing a marine battery. The benefit of this is that they’re able to provide sufficient starting power for the vessel’s engine using one connection and supply power to any on-board electrical systems with the other. Terminal designĪll YBX Active Marine batteries feature a dual terminal design. The dual in their name refers to this purpose. These battery types have thicker plates, ensuring they not only provide reliable starting power but also support for numerous hotel loads. These batteries are constructed for engine starting and to support minimal hotel loads.įor vessels with auxiliary systems such as navigation systems, lighting and other energy-intense applications, our YBX Active Dual Marine EFB batteries are the perfect fit. Our YBX Active Marine batteries are perfect for applications in which engine starting is the primary purpose. What battery technology you need depends on the specific power demands of your vessel. The Yuasa YBX Active Marine range features a wide variety of batteries, including EFB (Enhanced Flooded Battery) battery types. ![]() Understanding the power demands of your vessel is key to finding the right battery. ![]()
