How to Check the Health of Your Marine Battery in Fort Lauderdale, FL

November 27, 2018

You might know how to check the oil in your boat. You probably know how to check the fuel level. Most boat owners know a variety of simple maintenance tasks. But do you know how to check your marine battery in Fort Lauderdale, FL?

Since any boat will eventually need marine battery replacement in Fort Lauderdale, FL, it’s important to know how to check the battery. This maintenance task should be completed regularly. It’s also necessary if you experience electrical issues, to determine the cause and solution. Use the following overview to guide you through this process and keep your vessel in top condition.

Test #1: Open-Circuit Voltage Test

Using a multimeter, perform an open-circuit voltage test. This will determine if your boat has a good power source. It will tell you the battery’s state of charge. If the test reveals a charge of 12.6 volts or higher, the battery has a full charge. If it is below 11.7, the battery is discharged.

To perform this test, turn the multimeter selector to DC volts. Then, turn all the boat circuits off and turn the engine and charging system off. Once everything is shut down, touch the meter’s black lead to the battery’s negative terminal and the red lead to the positive terminal on your marine battery in Fort Lauderdale, FL. The resulting readout will tell you how well the battery is charged.

Test #2: The Voltage-Drop Test

Inevitably, a circuit loses electrical potential over time. A certain percentage of loss is expected and acceptable. However, faulty connections and corroded terminals can cause greater drops. Once you’ve completed the first test, move on to this one to check the voltage and VHF of your marine battery in Fort Lauderdale, FL.

First, turn on the appropriate breaker on the DC panel to ensure the battery and circuit you are testing are on, but keep all other circuits off. Then, turn the meter’s selector to DC volts. Touch the red lead to the positive terminal at the VHF, and the black lead to the negative. Compare the readout here to the voltage at the power source. If there is a drop of more than 1.2 V, you should check the system for issues.

Test #3: The Continuity Test

The flow of electricity in your boat’s system can be interrupted by a break in the circuits. This could be the result of a blown fuse or a corrosion issue. The continuity test will determine if a circuit is closed, as it should be, or if you have a break in the circuit.

To perform this test, first turn the meter’s switch to ohms. Then, turn off the circuit you want to test. Next, disconnect the ends of the circuit component. Connect the meter probes to each end of the conductor. If there is continuity, the meter should either beep or read near zero. A reading of “OL” indicates overload, meaning there is no continuity.
