Car Batteries VS Marine Batteries. What’s the difference?

Unlike car batteries which generally travel on smooth, sealed roads, marine batteries must be able to resist vibration from wave pounding and trailer transport.

Repeated vibration and wave impact on non-marine batteries can cause damage and cracks to appear in the battery’s internal components and outer case. This can cause shedding of active materials, accelerate corrosion, electrolyte leaks and ultimately lead to battery failure.

Car batteries are designed to deliver concentrated bursts of power to crank over and start the engine. The capacity used is replaced by the alternator which charges the battery during the journey. Marine batteries must not only have the starting power to crank over high compression engines but also provide the reserve capacity needed to run on board accessories.

When choosing a marine battery it is critical to invest in a battery that has been designed and manufactured specifically to handle the extreme demands of marine environments and modern marine electrical systems.
