A marine cranking battery (also known as a starting battery) is a type of battery designed specifically to start a boat's engine. It delivers a short burst of high current to crank the engine and then is recharged by the boat's alternator or generator while the engine runs. This type of battery is essential for marine applications where reliable engine ignition is critical.
Key Features of a Marine Cranking Battery:
- High Cold Cranking Amps (CCA): It provides a high current output to quickly start the engine, even in cold or harsh conditions.
- Short Duration Power: It's built to deliver quick bursts of power rather than sustained energy for long periods.
- Durability: Designed to withstand the vibration and shock common in marine environments.
- Not for Deep Cycling: Unlike deep-cycle marine batteries, cranking batteries are not meant to provide steady power over extended periods (e.g., powering trolling motors or electronics).
Applications:
- Starting inboard or outboard boat engines.
- Powering auxiliary systems briefly during engine start-up.
For boats with additional electrical loads like trolling motors, lights, or fish finders, a deep-cycle marine battery or a dual-purpose battery is typically used in conjunction with the cranking battery.
