How to Properly Maintain Your Marine Electrical System

With a lithium-powered marine electrical system, your bank of Battle Born Batteries will make up the “house bank.” This is powering all the electronics and equipment within your boat. Since a high amount of current is constantly running in and out of your batteries, it is essential that your connections to your battery terminals remain tight and clean. Any dirt or corrosion could lead the terminals to get hot, which could melt the insulation of the wires attached to them and even damage the batteries. Regularly, we recommend using two wrenches to check the connections on your battery terminals. It is best to use an insulated wrench with a rubber handle to prevent shorting across your terminals. In a pinch, if you don’t have an insulated wrench available, you can put heavy tape around the handle of your wrench to keep yourself and your batteries protected. Then, with both wrenches, check to make sure the connection on your battery terminal is as tight as possible. If you notice dirt or corrosion on your terminals, simply take the connection apart and clean it with a wire brush or sandpaper. Clean both sides well until any visible dirt or corrosion is gone. Then, add a small amount of dielectric grease to either side of the terminal and re-secure the connection.
Maintaining Proper Fusing
Over the course of time, your marine electrical system will continue to evolve and change as you modify your system and upgrade or reinstall various components. As you make changes to your system, it is essential that you are constantly thinking about your fuses. When parts of your system change, you may need to change a fuse to ensure it can handle the current. After completing any alteration to your system, simply do a quick audit of the fuses. Just to ensure they are all still able to function as intended.Maintaining Your Starting Bank
In addition to the batteries in your house bank, your boat also has a starting battery for the main engine. This is typically a lead-acid water-filled battery that requires regular maintenance beyond simply checking the terminal connections. Regularly, about once a month or so, you need to add distilled water to your battery. This will keep it filled properly, so you don't risk damaging it.
