What is the outcome of allowing battery terminals to corrode on a boat?

Allowing battery terminals to corrode on a boat leads to decreased electrical efficiency and can cause potential failure in electrical systems. When corrosion forms on the terminals, it creates resistance at the connection points. This resistance interferes with the electricity flow from the battery to the electrical systems, which can lead to malfunctions or inconsistent performance. As the efficiency of the electrical system declines, the boat's ability to operate its various systems effectively is compromised, resulting in issues such as dimming lights, poor engine performance, or total system failures. Moreover, if left unaddressed, the corrosion can further exacerbate these problems, leading to a more significant repair issue and possibly necessitating replacement of the battery or electrical components.
