What's the difference between a marine battery and a regular battery?

Marine batteries, unlike basic types of automotive batteries, are crafted to withstand harsh marine conditions. They endure the jolts and vibration from waves, ensuring performance where car batteries might fail. Because of this robust design, marine batteries often cost more than car batteries. Their job is not just to start an engine; they provide ongoing power to various onboard systems, making them indispensable for any seafarer.
