  • Generally more affordable than deep cycle batteries.
  • Cons:
  • Not as specialized as deep cycle or starting batteries.
  • May have shorter lifespan compared to dedicated deep cycle batteries.

Starting Batteries

Starting batteries, also known as cranking batteries, are specifically designed to deliver a high burst of power in a short amount of time to start an engine. These batteries have thinner plates than deep cycle batteries, allowing for rapid energy release.

If you primarily use your boat for short trips or frequent engine starts, a starting battery would be the most suitable choice.

Cost range for starting batteries:

  • Entry-level starting batteries can range from $50 to $100.
  • High-performance starting batteries can range from $100 to $250.

Pros and cons of starting batteries:

  • Pros:
