What could be a consequence of using the wrong battery type in a boat?

Using the wrong battery type in a boat can lead to a failure to start the engine due to incompatibility with the engine's requirements. Each engine has specific power needs, such as the required voltage and current output. If a battery does not meet these specifications—either by providing insufficient cranking power or not being able to sustain the necessary discharge rates—then the engine may not start at all.

Additionally, mismatched batteries can lead to other complications, such as the potential for battery damage or shortened lifespan. While other options may seem beneficial, they do not accurately reflect the reality of using an unsuitable battery type for marine applications, underscoring the importance of choosing the correct battery for reliable performance.
