• The main consideration in 4x4 and Automotive is often what will fit under the bonnet in the engine bay and give the most capacity (Amp-Hours) to run the fridge, while also being capable of dealing with some engine starting or winch use.
  • For internal use (inside the boot, under seats etc.) you need to use a fully sealed battery that will not give off gas while charging. Absorbed Glass Mat (AGM) is the best choice here.
  • We have listed our top choices for the "standard size" dual battery (i.e. to fit a 12inch N70ZZ size footprint). If you have less room to play with, or want to put the battery inside then just contact us for sizing and advice.
  • The Marine Pro range and Century Flooded range also come in smaller case sizes, or if you want a sealed battery then there are also smaller variants in the Optima and Lifeline ranges.
  • Note that batteries should never be put in a fully sealed box, there should always be some level of ventilation to allow for fault conditions or overcharging.
  • Ultimately the available space, charging solution and value for money will determine the best choice and we would be happy to help if you are in doubt.
  • We don't mind getting our hands dirty taking a look at and testing your set up if you can travel to us, or otherwise we can advise by phone or email if you just want to save money on the batteries or isolator system.
  • We have Cables, Cutters, Crimping & Soldering equipment and a wide range of connectors, terminals, battery chargers, dual battery systems and Solar panels. We fit Dual Battery Systems in Melbourne or can organise fitting for you if needed.
