3 Popular Marine Battery Cables


What You Need To Know About The Marine Battery Cable

The marine battery cable is a high-quality, durable cable made to handle harsh marine environments. These types of battery cables can withstand constant vibrations that the boat is subjected to, and to survive various other types of environmental conditions. Marine battery cables are also very flexible, making them the ideal choice to run easily through compact spaces on a boat.

Standard cables are often not suitable for handling these bends and turns which can compromise the overall integrity of the actual cable. This is why manufacturers of marine cables have developed unique models of battery cables for marine use that come with specialized insulating jackets. These cables are made for longevity, flexibility, and durability. In fact, marine battery cables are so durable and robust, that they usually out-last the battery.

To ensure that you are choosing the correct color cable, it is important to know what each color represents. The concept behind using different colors for this type of insulation is to ensure its intended use becomes obvious to any person working on the boat. This also ensures the process of replacing, repairing, or maintaining parts and wires is easier as the person working on the boat can easily identify these parts.

The Benefits Of The Marine Battery Cable

The Marine Battery Cable is a high-quality, durable cable made to withstand harsh marine environments. For a cable to last in marine environments, the cable must withstand the same vibrations that the boat is subjected to, along with surviving other types of environmental conditions. Another important quality that these cable types must have is flexibility. In most boats, wires often run through compact and tight spaces, along with making frequent bends and turns. This should not compromise the integrity or durability of the cable.

Here are a few of the important benefits linked to using a marine battery cable:

– They Resist Corrosion In Marine Environments

In most situations, copper is often used to provide resistance to elements such as corrosion or oxidation. This is why copper is mainly used in different types of cables. However, this situation changes when using copper in high humidity or wet environments. In these situations, copper oxidizes a lot faster than usual and corrosion weakens the copper cables. To make copper cables more resistant, they undergo electroplating, which is a process that adds a tin layer to the copper wires to provide protection from these harsh elements. Tin is resistant to corrosion, even in humid and wet environments.

– They Provide Premium Current-Carrying Capacity

The marine battery cable contains more copper when compared to automotive cables of a similar size. In most cases, automotive cables carry around 10% to 15% less copper when compared to the same-sized marine-grade cables. These higher levels of copper translate into a better capacity to carry current. Since marine-grade cables are able to withstand more current when compared to automotive cables, they also take a lot longer to overheat.

– They Feature A Flexible Design

Cables that are used on boats typically run through very tight and narrow spaces, especially those located in a hull. For this reason, it is vital that the marine battery cables are flexible and pliable.

Flexibility is a must when it comes to marine-grade wires. These wires include a PVC, or a special polyvinyl-chloride jacket, including insulation that is highly pliable. This is a feature that makes marine-grade wires flexible and pliable enough for boat use.

The wires and cables that are dedicated to marine-use provide benefits that make oceanic adventures much safer and easier. This is why it is important to choose the correct cable to enhance safety and reliability when you are out on the waters.
