Marine Batteries FAQ

There are four different chemical types of marine batteries available in the market: Absorbed Glass Mat (AGM), wet cell (flooded), gel cell and lithium. The right marine battery for your vehicle depends on your needs, the capacity, lifespan you are seeking as well as your budget.

If you are boating enthusiast, we understand that getting the best marine battery is paramount. However, when it comes to selecting the best marine battery, you need to take into account various factors such as whether you need a cranking battery or a deep cycle battery, cold cranking amps (CCA) needed, its reserve capacity and its amp hours. Enlist the help of your local R&J Batteries branch when choosing the best marine battery or boat battery for your application.

We strongly recommend using a dedicated marine battery to power your boat or leisure application as standard car batteries won’t have the necessary deep-cycling power or durability.

The terms “marine battery” and “deep cycle battery” are often used interchangeably as they share similar features. Deep Cycle Batteries are built for long lasting, continuous power and can be deeply discharged due to their thicker plates.

Most Marine batteries also have this deep-cycling feature although some are built just as boat starting batteries, or with both starting and deep cycling capabilities. Buying a dedicated marine battery ensures it has the features you need to power your boat and the necessary vibration resistance to make it last.

Marine batteries need to be able to resist vibration from wave pounding and trailer transport unlike car batteries which generally travel on smooth and well-maintained roads. Furthermore, car batteries are specifically designed to deliver bursts of power to crank over and start the engine. The alternator charges the battery during the journey. On the other hand, marine batteries need to have both starting power to crank over high compression engines as well as provide the reserve capacity to run accessories.

All marine batteries sold at R&J Batteries come with warranty. For specific warranty information, please contact your nearest R&J Batteries branch or visit the warranty page.
