Car Batteries VS 4x4 Batteries

car-vs-4x4-batteries-(1).pngUnlike car batteries which generally travel on smooth, sealed roads, 4x4 batteries must be able to resist the hard wear-and-tear of off-road driving.  Repeated vibration and impact from uneven tracks can cause damage and cracks to appear in a 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. Four Wheel Drive batteries must not only have the starting power to crank over larger high compression engines but also provide the reserve capacity needed to run auxiliary equipment such as winches, spotlights and GPS systems.
When choosing a 4x4 battery it is critical to invest in a battery that has been designed and manufactured specifically to handle the extreme demands of Australian off-road driving conditions and today's accessory-laden Four Wheel Drive vehicles.

Dual Battery Systems

In vehicles fitted with multiple accessories such as fridges and winches, 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 fridge, without compromising the performance of the starting battery.
Century has an extensive range of Deep Cycle batteries ideal for use in 4x4 dual battery systems.  Click on the link below for more information on the Century Deep Cycle range.
