Made for Boats…Just Boats

The Century Marine Pro range includes a comprehensive selection of superior quality marine batteries, incorporating advanced design features and specialist hard-wearing components for recreational or industrial marine applications.

Century Marine Pro batteries are equipped to handle the rigours of wave pounding, engine vibration and trailer transport while delivering reliable starting power and performance.

Marine Pro

Designed and manufactured in Australia, the Marine Pro is perfectly adapted to life on the water. Built using Platelock™ technology to combat wave pounding and engine vibration, with extra thick battery plates and active material for enhanced starting power and reserve capacity to run on-board accessories.

Marine Pro MF

Marine Pro Maintenance Free batteries are designed to provide reliable starting power for high compression engines up to 350HP, and sufficient reserve capacity for running basic marine electrics.

Marine Pro HD

The ultimate performance for heavy duty marine applications. Incorporating some of the toughest internal components in the industry, the Marine Pro HD provides starting and cycling power for both industrial and recreational vessels.

Marine Pro Cruiser

Low Maintenance, heavy duty starting batteries designed for use in larger marine craft. The Marine Pro Cruiser range features stronger internal components, specialist separators and thicker plates to withstand vibration and provide reliable performance in extreme conditions.


Featuring Optima’s patented SpiralCell™ technology, BlueTop batteries provide superior vibration and heat resistance. This means greater running time, faster recharge, longer shelf-life and up to twice the life of traditional marine batteries.

Car Batteries vs Marine Batteries

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, cause electrolyte leaks to occur 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 extensive electrical systems.

Dual Battery Systems

In boats fitted with multiple accessories such as fridges and lighting systems, a dual battery system utilising a secondary Deep Cycle battery is recommended.

Dual battery systems run a dedicated starting battery and a Deep Cycle battery in conjunction with each other. This allows the starting battery to be used for cranking the engine and then isolated when the engine is switched off. The Deep Cycle battery is then used to power accessories such as the lights, without compromising the performance of the starting battery.

Century has an extensive range of Deep Cycle batteries ideal for use in marine dual battery systems.
