Dual Batteries

A lot has changed in the passenger, light, marine and heavy duty battery world. Autospark keeps ahead of the latest and continually supplies only the best brands of battery, regardless of vehicle use.

A vehicle’s alternator effectively charges the car battery while the engine is running, but what about when it’s not?

Perfect For Your 4X4 & Camping Needs

Unfortunately, once the vehicle engine is shut down, the battery stops charging. Running portable 12V appliances while the vehicle is turned off will cause your battery to lose charge rapidly and go flat, which could leave you stranded in the outback with no way to start your car. The way to solve this problem is by installing dual batteries.

So how do they work? If you are planning to run electronics accessories in your car, caravan, trailer or 4×4, it is important to ensure you have enough power. Accessories such as winches, fridges, sound systems etc. can drain significant amps from your battery, faster than your alternator can replace them.

Dual Battery Systems

A dual-battery system consists of two batteries termed as the ‘primary battery’ and ‘auxiliary battery’. The two batteries are wired together to the discharging/charging system which integrates the vehicle’s electrical system and a battery isolator. An optional read out device can be placed in the cab during installation which gives you the ability to check your battery levels.

FAQ's

To keep your vehicle engine running smoothly, it’s crucial to understand the importance of a reliable car battery replacement. Below are the answers to some common car battery questions to get you started or help diagnose a problem.

Why choose an Exide Car Battery?
  1. Designed and built for Australian conditions including our sweltering summers and freezing winters so your battery won’t let you down
  2. Nationwide warranty with free extended warranty so you can always find an Exide service centre near you
  3. An Autospark battery price includes supply and professional installation so you know the job is done right
Why Do Batteries Fail?

Australia has some of the harshest environmental conditions in the world. The extreme temperatures and varied landscape can affect the life of a battery. Driving habits, vehicle type and battery age also impact life expectancy. Not all batteries are the same.

Autospark recommends Exide’s Range of batteries, designed to withstand the high under-bonnet temperatures and excessive vibration experienced by motorists. We have a full product range available, including automotive, marine, deep cycle and industrial batteries to provide customers with the best solution for every application.

How do driving habits affect my battery?

Short distance driving can cause your car battery to flatten over time. This is because your battery doesn’t have a chance to reach ‘full’ charge, which leads to accelerated corrosion and acid stratification. If you only use your car for short trips, long distance spins between them will help boost your battery’s health. Bad habits, such as skipping periodic car maintenance and using too much energy when idling also shorten battery life expectancy.

Can I install any Battery in my car?

It’s crucial the right car battery is purchased for your vehicle type and installed correctly to prevent battery problems. SUVs, 4WDs and other large off-road vehicles have different power needs the battery must cater for. Dual battery systems designed for these models can offer the right battery solutions. However smaller cars will be better suited to passenger vehicle batteries.

Other battery types, such as motorcycle batteries and marine batteries are not suitable for your car. They have a lower amperage output and are designed for deep discharge cycles.

How does heat affect my battery?

Heat is the number one killer of a battery. Although it increases the performance of car batteries short-term, their life is drastically reduced over time. Heat increases the rate of evaporation, which causes a loss of water from the electrolyte. Extreme heat also increases the rate of self-discharge and promotes the corrosion of the positive plate grids.

How long should my battery last?

Battery life is determined by various factors, with the most important being proper maintenance. Amount of use, proper charging and climate are other elements that also need to be considered. A battery that is stored for prolonged periods of time without use or recharging can develop sulfation on the plates. This greatly reduces the time and efficiency of how batteries perform.

How often should I replace my battery?

Car batteries generally last between four to six years. However, there are multiple factors to consider when determining how often a battery needs to be replaced including vehicle type, region/climate, driving habits, regular battery/car maintenance and whether the battery was installed correctly. If your current battery performance is unsatisfactory, consider upgrading your battery to suit your situation and driving needs.

How can I get maximum life out of my battery?

There are a few easy steps you can take to maximise the life expectancy of your battery:

Choose the right battery for your vehicle type
Ensure your battery is correctly installed
Check the top of the battery monthly to ensure it’s clean and free of corrosion
For maintainable batteries, remove plugs monthly to determine if there’s enough electrolyte covering the plates. Top up with distilled water if required or book in for a battery service
For maintenance free battery types, check the water indicator monthly
Charge batteries with an appropriate battery charger every three months to maintain peak performance

How much does a car battery cost?

The saying you get what you pay for reigns true with car batteries. Batteries vary in price depending on their cranking capacity (CCA rating), battery type and warranty. Generally, the longer the warranty the better the product. Batteries with a higher CCA rating tend to last longer and help your vehicle perform better. However, this is still dependent on other factors such as the strength of internal lead plates, how much electrolyte it contains and how well the battery has been built.

How should I dispose of my old battery?

Old batteries must be disposed of properly because of the toxins they contain, including lead and acid. They should be recycled at your local mechanic or battery repair outlet. If you have an old battery to dispose, you can speak to our staff at Autospark.

Are automobile batteries recyclable?

Exide Batteries, from Autospark, has a comprehensive business approach called Total Battery Management [TBM], that plays a leading role in one of Australia’s most effective and successful recycling programs. TBM encompasses manufacturing and distribution of lead-acid batteries, responsible collection and storage of spent batteries, safe transportation and reclamation of battery materials and use of those materials in the production of new batteries. Exide Technologies Batteries are also 98% recyclable.

You don’t have to wait until you break down to change your battery. Avoid breakdowns by getting your battery tested on a regular basis. Vehicle electrical systems are becoming more complex and its vital you purchase the right battery for your vehicle, so we recommend leaving it to the experts.

Customer Testimonials

"Great Advice"
I was wondering about utilising a CB Radio for my off-road trips and wanted some information on what would be best. I got some great advice and went on to get a GME unit fitted. I really appreciate the knowledge & help.
CHRIS J | SCARBOROUGH
"Saved Us"
I had noticed some strange electrical issues on my car. A visit to Myaree for some advice resulted in a battery test. It worked out that the battery was on the way out. Long story short, it ended up being a new battery.

I was thinking the worst, but was happy with the result. I have found this level of care quite rare these days. I highly recommend them.
JOHN H | MYAREE
"Lithium Outdoor Power"
The guys at Autospark were great with some excellent advice on power options for our weekend adventures. I didn’t know much about Battery Packs, but you guys sure did, so thank you very much for some great information on the Toppo unit we purchased.
TERRY K | KALAMUNDA
"Amazing Service"
I was travelling up north in WA when I ran into Craig (the owner of the Canning Vale and Myaree branch) after I had some battery trouble with a bad terminal. He fixed the issue in minutes and was happy to help, would definitely recommend this place for the amazing service and attention to detail. Given that this was a by chance offer for assistance, I can only imagine how great the branches are at what they do.
