Dual Battery Upgrades & Installations Central Coast

In need of a dual battery system for your car, truck, or 4×4 vehicle?
A dual battery system is a second battery for your vehicle, and it is also known as an auxiliary battery system. An auxiliary battery system is separate from your starting battery in your car. An auxiliary battery can be used to power a range of 12 volt accessories – fridge, air compressor, lights, kettle etc. It can also be used to charge devices like mobile phones, iPads, tablets, cameras. If you can charge it via USB – your dual battery system can keep it powered up.

Looking To Run Multiple Devices, Without Affecting Your Starting Battery?
Our Dual Battery Installation services are becoming increasingly popular for those who want to run multiple devices, whilst not affecting their starting battery.

Why Do I Need an auxiliary Battery Installation?
All cars have what is known as a starter battery which is used to start the engine and power the other components of your standard vehicle. As more accessories are added to vehicles like is normal for a camping vehicle the battery will become more strained and you run the risk of not being able to start your vehicle or power your accessories. This is why it's essential that you add an auxiliary battery to power the extras you need.

How Do We Design Dual Battery Systems?
There are several different types of dual battery systems available, including permanent in car or canopy installation or a battery box alternative. As these systems can become complex, we will ensure you get the right solution.
