Conclusion

The cranking battery for a boat is responsible for providing the initial power to start the engine. It is typically a 12-volt battery that is charged by the boat’s alternator while the engine is running.

The cranking battery is typically located in the engine compartment, and it is important to keep it well-ventilated to prevent it from overheating.
