Starter Batteries 

The comprehensive range of Marine Pro Batteries has been designed to meet all your engine starting requirements. With the quality of a Century battery you can rely on its ability to start your boat’s engine, run the normal accessories on board, and most importantly get you back to shore safely – think of your battery as your lifesaver. In addition, all marine batteries are specifically designed to handle the rigors of wave pounding and engine vibration.

The heavy power needs of some Optional Electrics may require the additional support of a dual battery system including a Deep Cycle Battery. Batteryworx carry a comprehensive range of Flooded and Gel Deep Cycle Batteries.

Note: The battery size and horse power rating is a guide for general engine and auxiliary load requirements. Some manufacturers of high performance engines may specify a minimum cranking amperage above this guide. Always check your engine manual for special requirements.
                   

Deep Cycle Batteries 

A Deep Cycle Battery is a lead acid battery designed to be deeply discharged and charged many times during its service life. It is designed specifically for powering electrical equipment for long periods of time. Deep Cycle batteries are constructed using thicker battery plates and denser active material, to withstand repeated charge and discharge cycles. In contrast, starter batteries are designed to deliver short, high-current bursts for cranking the engine, thus frequently discharging only a small part of their capacity.
                  

Types of Deep Cycle Batteries

Gel 

Century Deep Cycle Gel batteries utilise gel electrolyte technology, which holds the battery plates securely in an immobilised gel reducing movement within the battery. This design makes Century Deep Cycle Gel Batteries extremely robust in low rate discharge applications. The range is completely maintenance free and are non-spillable even if they are broken or damaged. The valve regulated sealed design enables installation in hard-to-reach locations and completely spill free.  

Flooded

Century Deep Cycle Flooded batteries are constructed using thicker plates, specialist antimonial lead alloys and denser active material to withstand repeated cycling (charging and discharging). The design allows easy access to maintain electrolyte levels for maximum control over battery life.

AGM 

Century Deep Cycle AGM (Absorbed Glass Mat) batteries are the ultimate in deep cycle technology and performance in high rate discharge applications. Featuring AGM technology, which suspends the electrolyte within porous glass fibre mat separators, the sealed Maintenance-Free design eliminates the possibility of acid spills or leaks and electrolyte levels never need topping up.
