Battery know-how
Your car battery, explained
Most drivers do not think about their battery until it is dead. Six things worth knowing before that happens.
The basics
How does a car battery work?
It is the heart of your car's electrical system.
- Battery sends power
- Starter motor cranks
- Engine runs
- Alternator recharges
It also powers the ignition and fuel system, and the alternator keeps it topped up while you drive.
Warning signs
Signs you need a new battery
- Slow or no start. Capacity drops with age until it cannot crank the engine.
- Battery warning light. Something in the battery or charging system is wrong.
- Dim lights, flickering electrics. The battery is struggling to supply power.
What drains it
What affects the charge?
- Short trips. The alternator never gets time to recharge it fully.
- Heat and cold. Heat shortens battery life; cold slows the chemistry.
- Poor fitting. A bad install can damage modern electronics.
Buying tips
Choosing the right battery
- Right size. It must sit tight in the tray so vibration cannot damage it.
- Under 6 months old. Check the date code before you buy.
- Good reserve capacity. Keeps essentials running if the alternator fails.
~1hour, usually
We come to you, test the battery and replace it if needed.
50months, up to
Nationwide roadside warranty, depending on the battery.
Questions
Mobile battery replacement FAQs
The ones we are asked most. Tap a question to see the answer.
How much does a car battery replacement cost in Sydney?
It depends on your vehicle and the battery it needs. Quality batteries for small cars start from $195 with a 2-year warranty, and heavy-duty options for larger cars and SUVs start from $244 with a 3-year nationwide warranty. Fitting and battery testing are free, and you get a firm price before any work starts.
Do you come to me?
Yes. Our mobile team comes to your home, workplace, car park or the roadside anywhere in the Sydney metropolitan area, 24 hours a day, 7 days a week. No membership is needed. You only pay when you need us.
How quickly can you get to me?
Usually within the hour. It depends on traffic and where you are, and we give you an honest arrival time when you call. Our vans carry the common battery sizes, so most jobs are tested and fitted on the same visit.
Do you test the battery before replacing it?
Yes. Every callout starts with a free test of the battery, alternator and charging system. A flat battery is often a symptom rather than the fault, and you only pay for a battery if you actually need one.
What warranty comes with a new battery?
Every Battery Brothers car battery comes with a nationwide roadside warranty of up to 50 months, depending on the battery you choose.
Do you only replace car batteries?
No. We also replace truck, motorbike and scooter, 4WD, caravan, marine and boat, and standby generator batteries, and look after commercial fleets with scheduled testing and bulk replacement.
Do you take my old battery?
Yes. Your old battery is taken away and recycled free of charge on every job.
