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.

Installation locations

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.

Common installation locations include:

Dual battery systems are a popular choice for off-road enthusiasts. A reliable backup battery to start your vehicle when you are off the beaten track is a weight off your shoulders. A dual battery setup for your 4×4 vehicle will ensure you are always equipped for your next adventure.

Dual battery setup for your camper trailer

If you love the great outdoors, there’s a good chance you enjoy getting out in your camper trailer. A dual battery setup in your camper trailer makes cooking and running appliances a breeze. The added benefit of being able to power a lighting system for your campsite at night is also a huge advantage.

Everyone at Voltaic were very friendly and very knowledgeable about the services I required. I was able to get in within a week of me calling up where i wouldn't have been able to get in until 2025 for the more commercialised companies like ironman 4x4 and TJM. I am very happy with the service they provided. I will be coming back for more work on our 4x4

Daniel Ripp

I found Voltaic Auto Electrical after looking for a 12v system for my Ford Ranger over a year ago, i ended up going with one of the battery box setups as i don't require constant power in my tub. The service and quality I received on that initial job has guaranteed them a client for life. I will always go to Voltaic for all my auto electrical work and have been back for tail lights, rear lights, electrical tidying, and no doubt I will be back for more in the future.Big thanks to the team at Voltaic.They also have great merchandise.

My car air-conditioning was blowing warm air, so I wanted it checked before the hot Perth summer arrived. I received fantastic customer service from Voltaic from start to finish. Friendly customer service, honest feedback to advise that due to the age of my car, it might be an expensive repair, speedy diagnosis and repair which ended in happy news - my gas needed topping up and a filter change. I would thoroughly recommend Voltaic Auto Electrical.

Martin Abbott

The Team at Voltaic pulled out all stops to have our vehicle fitted with a UHF radio and flashing beacon at short notice and no compromise with the quality of work carried out. Excellent service, thank you.

Rob Warrilow

Can't fault them . Great service . Very polite and helpful. I'd recommend them for any of their auto electrical services .

Vanessa Hayes (Nessa)

Friendly, helpful staff, fair pricing..Had a UHF radio/aerial installed by someone else that wasn't performing as expected so bought a new one. They took the old one out & put the new one in, in no time! Also grateful that they didn't use the aerial mount provided because it would have damaged my paintwork, and instead found a different mount that worked. I'll have no hesitation in taking my car back here for future installs!

daniel woods

Steve Lindley

Was very happy with the workmanship from Voltaic and Deon when fault finding my Redarc issues. They were prompt and precise with every detail, and kept me in a constant loop of feedback when required. In my previous roles I would audit businesses and part of this was their workshop. I would be happy to say, I was impressed by the layout and cleanliness of the workshop from an exterior viewing. I would be contacting them again when next in Perth for any auto electrical work I may have.

Peter Haslam

Doug Hubble

My 10 year old Hyundai has had poor aircon for some time and decided to do something about it. Voltaic was recommended by my regular mechanic so I called by late on Friday. They offered to run a diagnostic test then and there and the outcome was they could book me in first thing on Monday. It was all over by 10am when they called. I collected the car with some very cold air flowing and paid my $199 which I was thrilled. The service by all concerned was first rate and the outcome is better than I hoped.I will gladly recommend them to anyone and will very happily return when needed. Thanks to all concerned.

Danyul Lowe

They do their damn best and actually explain the work they did in a way you can understand.

FAQs

How much does a dual battery system cost?

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 $1900 including the cost of the battery and equipment required for the system.

How long does it take to install a dual battery system?

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

What is the best type of battery for a dual battery system?

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.

What is a deep cycle 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.

How does a dual battery system charge?

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.
