Deep cycle marine batteries are designed to supply a steady source of power to a vessel, without draining quickly. They are perfect for powering all sorts of marine electronics, such as trolling motors, fish finders, and GPS systems. However, due to the nature of marine conditions, these batteries can suffer from a variety of issues over time, including clicking. In this article, we’ll look at how to tell if a deep cycle marine battery is clicking, what causes it, and how to troubleshoot it.
What Does it Mean When a Deep Cycle Marine Battery Clicks?
When a deep cycle marine battery clicks, it’s usually a sign of an issue with the battery. The clicking is caused by the internal electrical connections in the battery, which can become corroded over time. When this happens, the connections can’t conduct electricity effectively, and they start to click. The clicking can be heard as a faint clicking, or a loud thumping noise, depending on the severity of the issue. Additionally, the clicking can become more frequent as the battery’s condition worsens, so it’s important to address the issue as soon as possible.
What Causes Deep Cycle Marine Battery Clicking?
Deep cycle marine battery clicking is usually caused by corrosion on the internal electrical connections. Corrosion can build up over time due to exposure to moisture, heat, and other factors. Additionally, if the battery has been deeply discharged, it can cause a build-up of corrosion on the internal connections. This can disrupt the flow of electricity, leading to clicking and other issues.
How to Troubleshoot Deep Cycle Marine Battery Clicking
If a deep cycle marine battery is clicking, it’s important to troubleshoot it as soon as possible. The first step is to check the battery’s connections. Corrosion can build up over time, blocking the flow of electricity. If corrosion is present, it can be cleaned off with a wire brush. Additionally, the connections should be checked for loose connections, which can cause clicking as well.
The next step is to check for voltage fluctuations. If the battery’s voltage drops too low or gets too high, it can cause clicking, as well as other issues. A multimeter can be used to check the battery’s voltage, and it should be in the range of 12.6-13.2 volts when the battery is idle. If the voltage is outside of this range, it can indicate an issue with the battery.
The last step is to check the health of the battery itself. A deep cycle marine battery should last a long time, but over time it can become damaged and degraded. If the battery is damaged, it can cause clicking, as well as other issues. A battery tester can be used to check the battery’s health, and if it’s damaged, it should be replaced.
Conclusion
Deep cycle marine batteries clicking can be a sign of an issue with the battery. The clicking is usually caused by corrosion on the internal electrical connections, or voltage fluctuations. It’s important to troubleshoot the battery as soon as possible, by checking the connections, voltage, and health of the battery. If the issue is severe, it’s best to replace the battery to ensure a safe and reliable source of power.
