Battery Replacement - What You Need To Know

What is a Battery?

Most people will know what a battery is - the world we live in today practically runs on batteries! Just like your mobile phone, a car is a “mobile” electronic device which also needs a battery. All batteries work in the same way, an energy storage device which uses chemicals to produce electricity. When we use a battery those chemicals are producing energy, then when the battery is empty we can recharge the battery to replenish the energy. A car battery generally uses lead and a type of acid to store energy, which is why they are sometimes called “lead acid batteries”. Most people are aware that a car has a battery. A battery serves two purposes in your car: to provide all the electrical power when the engine is not running, and then to stabilize the electrical power supply when the engine is running. The primary use of the battery is to start your car which takes a lot of power, making it an essential component.

What are the signs that you need a new car battery?

How do you know if your car battery needs replacement? Just like the battery in your phone, and in fact any battery, over time the capacity of a car battery will reduce until the point at which is will be difficult to retain a charge. Adding to this a car battery is generally working in a fairly hostile environment under the bonnet of your car exposed to a lot of heat, vibration and stress.

The unfortunate thing with car batteries is often they will fail quickly with little to no warning, and from one minute to the next will stop working. This is why it’s especially important that your battery is checked with every service by a qualified mechanic and that you get your car serviced regularly. The most obvious sign of a flat battery is that nothing happens when you try to start the car.

However in some cases you may notice the car difficult to start – it may take longer than normal and you may even hear a different sound as the starter motor struggles to start the engine. Sometimes a very rapid clicking can be heard which is the sound of the starting circuit trying to work with a lower voltage than usual. Also you may notice that the lights on the dashboard do not illuminate as well as they do normally, or flicker as you try to start the car. Less obvious signs are electrical abnormalities or gremlins such as flickering lights or even poor performance whilst the engine is running as the battery is failing to stabilize the power supply correctly.

How much does a new battery cost for a car?

Generally speaking, a new car battery will cost between $500 and $1000 or even higher in some cases depending on the vehicle and engine size. The average life of a car battery is approximately five years. It’s crucial to ensure that a battery issue is correctly diagnosed before investing the money in a replacement, as there are other factors than the battery itself which can lead to it going flat.
If you have taken the time to read this guide up to this point, it is clear that you take care of your car diligently. When you need a car service, repair, or inspection for your vehicle in the future, contact us at CB Auto Service today. We are here to help you.

Charlie was both friendly and professional. I was able to grab a coffee and bite up the road as he only took 40minutes to service the car. He was great at explaining the issue with the car, even used props. I'll be going back to him in the future!

Live locally to Charlie and even if I lived 2 hours away I'd still drive all that way for him to service my car. Best guy, super helpful and explains things in detail. Couldn't recommend him enough!

I got a service from Charlie at my home address and it was a smooth and professional operation.He was on time, polite, knowledgeable, fair in pricing and efficient.He also didn’t speak down to me regarding my vehicle which does irritate me with some mechanics.I was so happy with the service he provided I’d use him for any future work he’s set up to do and I’d 100% recommend him to anyone.

Charlie made what is normally an ordeal for me (sorting out how to get to and from a mechanic, only to be sold a bunch of unnecessary extras) an absolute breeze. Honest, friendly and refreshingly free of BS, Charlie got to it while I sat in a cafe munching on the smashed avo toast I could afford from not going to a big garage franchise.You've got my continued business, mate, and that of the friends and family who I'll be directing your way!

Flexible, reliable and efficient car service from Charlie at CB Auto Service. Was even able to reschedule me dropping the car to him at his home workshop short notice. Would recommend to friends and use his mechanical servicing again. Thanks

Charlie was good enough to make time to service my car before I drove down south. He was efficient and thorough and reasonably priced. Absolutely recommend CB Auto Service.

Hi! Charlie came out to us to attend to an annoying issue with our son's car leaking oil. The problem is still being sorted, but Charlie has been great, offering good old fashioned service that is so hard to come by these days. He is reliable, very thorough, and is keeping us well informed with where he is at with regards to accessing parts etc. We highly recommend his very convenient service.

If I lived in Perth, Charlie would definitely be my mechanic!. I arrived in Perth with less than 24 hours until I traded in my vehicle and its showing an orange engine code. I felt sick... Even though I never got to meet Charlie, I will be forever grateful for his text messages with very valuable advice. Charlie, I really hope I get to hand over some money to you one day because you are an absolute gem!! When your a tradesman your time is so valuable and you gave me yours for free..... You deserve all the money and customers in the world. I wish there were more people in the world like you. Thank you so much. I love that you love running your own business! You are exactly where you need to be 🙂

Charlie is a great guy he performed a logbook service on my car, he arrived on time, his work is very clean and meticulous attention to detail. His pricing is comparable to what I’ve been paying at garages. He is happy to show and explain any genuine issues with the car, and can even diagnose and reset your cars computer, something other garages don’t often do. No more missing work or getting a taxi or friend to pick you up, most services are complete in under two hours so you don’t loose your car for the whole day.

Charlie was very thorough with checking all possible causes to try and find the issue with my Hyundai Elantra. He was great at explaining in layman’s terms what he was doing and what could be the problem. Charlie was very honest when he said he was only 80% sure it was the fuel pump and agreed when I said I’d get a Hyundai Dealer service department to look at it too. Charlie is excellent with communication, including phone calls and answering texts, and also punctual - coming to look at my car at the time he said he would. He’s a trustworthy guy and I’m getting a quote to replace the fuel pump 🙂

Charlie is an awesome mechanic. Super quick to diagnose the intermittent fault I’ve been having with my car for over 2 years. He was happy to share his wealth of knowledge to help me understand the problem too. I highly recommend him.

Charlie was honest, friendly and reliable, arriving exactly at our agreed time. He completed the alternator exchange quickly and efficiently and the cost was exactly what he had quoted. Great service and I would have no hesitation in recommending Charlie at all. Thanks again Charlie for the great service.
