Car batteries in Australia

Updated 5 November 2026

A car battery in Australia currently costs between about A$120 and A$400, and most standard batteries for mid-size cars sit between A$190 and A$250. The quickest way to get the current price for your exact car is to create a request on BlaBlaPrice: the AI checks sellers' websites and price lists in Australia and shows you the batteries and businesses it finds.

Warranty and the receipt

Under the Australian Consumer Law, a seller cannot exclude the guarantees on goods, and for a major failure you are entitled to a replacement or a refund. Battery makers also give their own warranties, which usually run from six to 36 months depending on the brand and the vehicle. The replacement period normally starts on the date of purchase, and claims usually need dated proof of purchase, so keep the receipt with your car papers.

Heat is the usual problem

From December to February the summer heat in Brisbane, Perth and Adelaide is hard on batteries, and a battery that is already weak often fails on the first hot morning. Winter, June to August, is milder in most of the country, although cold mornings in Melbourne and Adelaide still show up a tired battery. Check the cold cranking amps (CCA) figure against your car's handbook, because a bigger number is not automatically the better choice.

How batteries are sized and fitted

Batteries are sold by a size code such as 55D23L, NS40ZL or DIN65, and the letters at the end describe the terminal layout, so check which side the positive terminal sits on in your car before you order. Sizes are given in millimetres, and the code is enough to find the right tray, so you rarely need to measure. Ask the seller whether fitting and recycling of the old battery are included in the price, because the figure quoted is not always the final cost.

What to put in your request

Give the make, model and year of the car, the code printed on the old battery if you can read it, and whether the car has start-stop. Say whether you want the old battery taken away, which city you are in (Sydney, Melbourne, Brisbane, Perth or Adelaide) and your budget. The more exact the request, the less back-and-forth you need before you can compare offers.

Creating a request is free for buyers. You describe the battery you need in your own words, and sellers registered on BlaBlaPrice reply in the chat with their offer: price, terms and delivery. Your contacts stay hidden until you decide with whom to exchange them. You can also send the request link to a battery supplier you already know, by SMS, e-mail or WhatsApp. For related parts see Car parts, or start from the home page.
