Marine Battery & Cable Maintenance

Your boat’s battery is necessary to start the engine, power the electrical system, including lights and navigation, and much more.

For boats powered by a trolling motor, it i the only power source for the vessel.

Without it, you would be dead in the water.

With that said, here are some high-level ways to take care of your marine battery and cables.

Protect and Clean the Terminals
The easiest aspect of marine battery maintenance is to keep the terminals clean. Over time, discharge will exude from the terminals, and this corrosion can damage the battery and make it difficult to establish a solid electrical connection.

Use a solution of warm water and baking soda with a battery terminal brush or a steel wire brush to scrub them clean from time to time.

Then, apply some dielectric grease to the terminals. A thin coating will help prevent water ingress and almost entirely prevent corrosion.

Keep the Battery Charged
A fully charged battery will last longer than one that is fully discharged and allowed to remain at a low level. If possible, you should never allow your battery to die.

Keep your battery fully charged before leaving port. When in port, you may want to hook it up to a battery maintainer with a trickle charge function.

Protect It Against Extreme Temperatures
For small vessels that are removed from the water during the winter, it might be a good idea to remove your battery when your vessel is dry-docked.

Keep it somewhere that preferably won’t experience freezing temperatures, as these can damage batteries, and keep it charged throughout the winter.

Use Only Approved Marine Battery Cable
For wiring purposes and battery leads, it is important to use only USCG and UL-approved marine battery cables.

Marine battery cable is made with very thin copper conductors that are individually tinned. This does two things: it makes them very flexible, and it helps prevent corrosion as the tinned copper is better insulated.

Use the Right Size Marine Battery Cable
It is also critical to use the right gauge of marine-grade wire for the application.

The use of a wire in a gauge that is inappropriate for the load of the circuit will cause the wire to overheat, can cause the insulation to break down, and can cause fires.

Protect Against Chafing
Be cognizant of where the cable exits and enters from any compartments in your vessel. These are all chafing points.

If the wire’s insulation chafes and wears through, you’re at a much higher risk of fire.

Instead, protect your cables with conduit, electrical tape, silicone, or some other buffer at entry points. Consult a marine electrical engineer if you have questions.

Common Questions About Security and Alarm Cables, Answered

Not sure which type of security or alarm cable your facility or system needs? Hopefully, these answers to common questions can help! What cable is used for alarm systems? Security and alarm systems are usually wired with small-gauge wire specifically designed for the purpose. For instance, many security systems are wired with 12 and 18 AWG gauge alarm wire, as these low-voltage applications do not necessarily require larger, heavier wires. However, larger or wire gauges may be required depending on the circumstances. Also, there are some unique requirements for some systems. For instance, fire alarm cables must be made with specific insulation that is heat resistant and which does not produce toxic smoke when burned. What gauge cable do you need for alarm systems? Only your specific system requirements can answer that question, but often large wire gauges (that is, smaller wires) are used as security and alarm cables because of the low-voltage, low-current application. What is ...

Buying Quality Marine Electrical Wire

When it comes to wiring in marine environments, you have to start with a new set of rules. The American Boat and Yacht Council (ABYC) has its own set of guidelines that differ significantly from wiring in terrestrial applications. Before you start your next marine wiring project, it’s important to reference these guidelines to ensure you are using the proper marine electrical wire and proper terminal connections to avoid the possibility of potentially catastrophic electrical failure. Knowing what to look for before you purchase your wire can help ensure that your boat is wired safely. Marine environments have to deal with a lot of movement. Between the gentle rocking that experienced in your dock or harbor to the violent jarring when cutting through the waves, boats almost never standstill. Because of all this movement, it’s crucial to have flexible cables that can move without cracking their insulation or coming disconnected. In order to achieve this level of flexibility, marin...

Factors to Look Out for When Selecting a Boat Battery Cable

Whether you’re an experienced boater or just getting started, it’s important to make sure your boat is properly outfitted with the right battery cables. Boat batteries provide power to the many electrical components of your boat, and the battery cables are responsible for transferring that power safely and efficiently. Selecting the right cables is essential to making sure your boat runs smoothly and that you’re able to enjoy your time on the water. When selecting boat battery cables , there are a few key characteristics to look for. High-Quality and Marine Grade First, you’ll want to look for cables that are made from high-quality materials that can withstand the elements. The cables should be able to handle the rigors of a marine environment, including exposure to saltwater, UV rays, and extreme temperatures. Additionally, you’ll want to make sure the cables are flexible and easy to install, as this will make the job of connecting the cables to your ba...
