Dual battery installation Perth

Make a second battery your first thought

Dual battery system installation.

As the name suggests, a dual battery system is where you have a second battery installed in your vehicle. This allows you to continue running accessories without draining your main (starter) battery. Dual battery systems are ideal if you enjoy camping or off-roading, where you often need to power a fridge, radio, or lighting system. The team at Voltaic are equipped with the knowledge and tools to provide a high-quality dual battery installation in Perth.

Dual battery installation location.

We can perform a dual battery installation on most vehicles. The key is to ensure the secondary system is isolated from your main system, so your starter battery does not flatten. A dual battery system can be installed in a variety of places in your car, depending on your vehicle type and usage requirements.

Frequently asked questions.

The cost of a dual battery system depends on the type of battery you choose, your vehicle type, and where you want it installed. Our rates start from $1400 including the cost of the battery and equipment required for the system.

Installation typically takes 6-8 hours depending on the type of system, your chosen installation location, and the complexity of the work involved.

The type of battery to choose for your dual battery system depends on how much you wish to spend and where you would like it installed in your vehicle. We recommend a deep cycle wet-cell battery for installation under the bonnet or in the tray of your ute. This type of battery tends to build up gasses during charging, so it needs to be away from vehicle occupants. If you would like to install the battery in your vehicle’s cabin or in a canopy, we recommend one that won’t leak, spill, or emit gasses, such as a deep cycle AGM, lithium, or gel battery.

Deep cycle batteries differ from regular car batteries in that they are constructed with thicker battery plates and denser active material. This helps them withstand the repeated charge and discharge cycles of a dual battery system.

The simplest method of charging your second battery is by using your vehicle’s alternator. The battery charges while you are driving your vehicle, in the same way as your main (starter) battery. When installing your dual battery system, we isolate the second battery from your main battery to ensure your main battery does not flatten.
