Dual Battery Systems
Looking To Run Multiple Devices, Without Affecting Your Starting Battery?
Dual batteries are becoming increasingly popular for those who want to run multiple devices, whilst not affecting their starting battery. Whether it’s a fridge, a phone, a tablet or even your night-time lights for camping, our team can help you organise the dual battery system to suit your needs. 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 are always willing to discuss options prior to making any big decisions.
Why Do I Need A Dual Battery System?
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.
What Dual Battery System Options Are There?
There are a number of different ways you can set up your dual battery system and the one we recommend will depend on a number of different factors. Here are some of the different ways a dual battery system can be set up:
1. Basic Isolators
Similar to dual battery systems of the past a basic isolator is like a manual switch however it instead of being able to control the switch yourself it is instead controlled by the ignition. A basic isolator is the most cost effective style of dual battery system.
2. Smart Isolators
A smart isolator has the same switch as a basic isolator but rather than being controlled by the ignition it is instead turned on and off at certain voltages. This option is more expensive than the basic isolator but we recommend this option as they’re able to keep the auxiliary battery disconnected until the starter battery is fully charged meaning that you will always have enough power to start your engine.
3. DCDC Charging System
This is what we recommend installing in your vehicle if you have a second battery in your car. If you have a lithium battery the smart charging stages will also increase the battery life and efficiency both when running your battery and not.
What Battery Types Can You Use?
There are a number of different types of batteries to suit any kind of budget and requirements which will allow you greater flexibility in the set up of your dual battery system. Our team will be able to provide recommendations on which battery type will work best in your situation. Here are some of the battery types you can have in your set up:
1. Flooded Lead Acid Battery
Flooded Lead Acid Battery these are the oldest and most common and cheapest type of batteries in use. They can handle regular starting of the engine which makes them a greater starter battery.
2. Absorbent Glass Mat
Absorbent Glass Mat batteries are essentially leak-proof which means that they are safe to install in any configuration. This coupled with their slow discharge rate means that these batteries are a great option for an auxiliary battery if the space in your vehicle is limited.
3. Gel Cell
Gel cell batteries use gel acid rather than liquid acid used in AGM batteries which makes them spill proof and maintenance free.
Lithium batteries are slowly becoming more popular in cars as they are lightweight and powerful making them the ultimate battery technology.
