A flat battery rarely announces itself at a convenient time. Whether it’s a cold Monday morning or you’re rushing to an important meeting, a dead car battery can derail your entire day. The good news? You can now buy car battery online Australia-wide from reputable retailers who’ll deliver straight to your door, often with next-day shipping.
At National Cover, we specialise in motor insurance and understand what it takes to keep Australian drivers protected and on the road. While we focus on comprehensive coverage and expert claims support for when things go wrong, we also know that proactive maintenance, like replacing an ageing battery before it fails, saves you time, money, and stress.
This guide covers the five best online stores where you can purchase a quality car battery in Australia. We’ve evaluated each option based on pricing, delivery speed, and fitment tools to help you make a confident choice.
1. Supercheap Auto
Supercheap Auto operates one of Australia’s largest automotive retail networks, and their online store makes it easy to find and purchase a replacement battery without leaving home. You’ll find a straightforward buying process backed by physical stores nationwide if you need in-person support.
Range and battery types available
Supercheap Auto stocks batteries from trusted brands including Century, Varta, and Optima, covering everything from standard lead-acid models to AGM (Absorbed Glass Mat) batteries for vehicles with start-stop technology. Their range suits passenger cars, 4WDs, motorcycles, and marine applications, with clear specifications listed for each product.
Rego search and fitment confidence
You can enter your vehicle registration number on their website to filter batteries that match your car’s exact specifications. This tool removes the guesswork around Cold Cranking Amps (CCA) and terminal placement, ensuring you order the correct battery the first time. Detailed product pages also list compatible makes and models.
"The rego search tool saves you from ordering the wrong size or specification, which is the most common mistake when buying batteries online."
Delivery, click and collect, and in-store help
Supercheap Auto offers home delivery across Australia, typically within 2 to 5 business days depending on your location. You can also choose click and collect to pick up your battery from a nearby store, often on the same day. Staff at physical locations can assist with fitment advice or even install the battery for a small fee.
Warranty, returns, and battery recycling
Most batteries come with manufacturer warranties ranging from 12 to 48 months, clearly stated on each product page. Supercheap Auto accepts returns within 30 days if you change your mind, and they’ll recycle your old battery for free when you drop it off at any store.
Best for and watch-outs
Supercheap Auto suits drivers who want a reliable national retailer with both online convenience and in-store backup. Watch out for delivery times to remote areas, which can stretch beyond a week during busy periods.
2. Battery World
Battery World specialises exclusively in batteries and power solutions, giving them deep expertise across automotive, marine, and commercial applications. Their nationwide network of stores combines with a functional online platform, allowing you to purchase online and access local support when needed.
Range and battery types available
Battery World stocks premium brands like Exide, Yuasa, and their own Century line, covering standard flooded batteries through to enhanced flooded batteries (EFB) and AGM types for modern vehicles. You’ll find options for passenger cars, commercial vehicles, motorcycles, and caravans.
Vehicle lookup and expert fitment help
Their website includes a vehicle search tool that filters batteries by make, model, and year. Battery World also employs trained staff across their stores who can verify specifications over the phone, helping you confirm the right CCA rating and terminal type before purchase.
Delivery and mobile battery replacement options
Battery World delivers to most Australian metro areas within 2 to 4 business days, and many stores offer a mobile fitting service where technicians come to your location, install the new battery, and remove the old one. This option suits drivers who can’t easily reach a workshop.
Warranty, returns, and battery recycling
Warranties typically range from 18 to 36 months depending on the battery type, with clear terms provided at purchase. Battery World accepts free battery recycling at any store location and handles returns within 14 days if the product arrives damaged.
Best for and watch-outs
Battery World works well for drivers who value specialist knowledge and prefer speaking with battery experts. Delivery to regional areas can take longer than larger automotive retailers.
3. Repco
Repco has served Australian motorists since 1922, building a reputation for quality auto parts and expert advice. Their online platform allows you to purchase batteries with confidence, backed by nationwide store locations where you can collect your order or get hands-on assistance.
Range and battery types available
Repco stocks batteries from Century, Exide, and Bosch, covering standard lead-acid batteries through to AGM and calcium models for vehicles with advanced electrical systems. Their range suits passenger cars, light commercials, 4WDs, and performance vehicles, with specifications clearly displayed for each product.
Rego search and matching the correct specs
You can enter your registration number on Repco’s website to find batteries that match your vehicle’s exact requirements. This tool filters by CCA rating, terminal type, and physical dimensions, ensuring you order the correct battery without manually checking specifications.
Delivery, click and collect, and installation support
Repco offers home delivery across Australia, typically arriving within 3 to 5 business days. You can also select click and collect to pick up from your nearest store, often within 24 hours. Many Repco locations provide battery installation services for a reasonable fee.
"Repco’s rego search removes the risk of ordering an incompatible battery, which is especially helpful for newer vehicles with specific electrical requirements."
Warranty, returns, and battery recycling
Batteries come with manufacturer warranties between 12 and 36 months, clearly listed on each product page. Repco accepts returns within 30 days and offers free battery recycling at all store locations.
Best for and watch-outs
Repco suits drivers who value established automotive expertise and want access to physical stores for support. Delivery times to rural areas can extend beyond standard estimates.
4. Auto Battery Online
Auto Battery Online operates as a dedicated online-only retailer, focusing exclusively on car batteries without maintaining physical stores. This approach allows them to offer competitive pricing while delivering across Australia, though you’ll need to rely on specifications rather than a registration search tool.
Range and battery types available
Auto Battery Online stocks batteries from Century and Exide, covering standard flooded batteries through to AGM types for vehicles with start-stop systems. Their catalogue includes options for passenger vehicles, 4WDs, and light commercial applications, with each listing displaying CCA ratings and dimensions.
Finding the right battery without a rego tool
You’ll need to match your battery manually using make, model, and year from their category filters. Auto Battery Online provides detailed specifications for each product, but verifying compatibility requires you to check your current battery’s specifications or consult your vehicle manual before ordering.
Delivery coverage and dispatch expectations
They deliver nationwide with metro deliveries typically arriving within 2 to 4 business days. Regional areas may require additional time, and you can track your order through standard Australia Post or courier services.
Warranty, returns, and battery recycling
Batteries include manufacturer warranties between 12 and 30 months. Returns are accepted within 14 days for unused products, though you’ll need to arrange battery disposal separately as they don’t operate recycling drop-off points.
Best for and watch-outs
Auto Battery Online suits budget-conscious drivers who know their battery specifications. Without a rego search tool or physical stores, you must verify fitment independently.
5. Marshall Batteries
Marshall Batteries operates as a specialist provider with a focus on emergency battery replacement and mobile service, making them ideal for drivers who need immediate assistance. Their online platform allows you to purchase batteries with the option of professional installation at your location.
Range and battery types available
Marshall Batteries stocks premium brands including Century, Exide, and Varta, covering standard flooded batteries through to AGM models for modern vehicles with start-stop systems. Their range suits passenger cars, SUVs, European vehicles, and commercial applications, with specifications clearly listed for each product.
Getting matched to the right battery fast
You can contact Marshall Batteries directly through their website or phone service to receive expert recommendations based on your vehicle’s make and model. Their team verifies the correct CCA rating and terminal configuration before confirming your order, removing the uncertainty when you buy car battery online Australia-wide.
24-7 replacement and onsite fitting
Marshall Batteries provides round-the-clock mobile service across major metro areas, sending qualified technicians to install your new battery at home, work, or roadside. This service operates seven days a week, making them valuable for urgent replacements.
"24-7 mobile fitting means you don’t need to organise towing or drive on a failing battery to reach a workshop."
Warranty, returns, and battery recycling
Batteries include manufacturer warranties between 18 and 36 months. Marshall Batteries handles free old battery removal during installation and manages proper recycling through certified facilities.
Best for and watch-outs
Marshall Batteries suits drivers needing immediate replacement with professional installation. Their mobile service typically costs more than standard delivery options.
A quick way to choose the right store
Your choice depends on what you value most in the buying process. If you need a battery today with guaranteed fitment, Supercheap Auto or Repco offer rego search tools plus nationwide stores for immediate collection. Drivers who want specialist advice should consider Battery World or Marshall Batteries, both providing expert consultations to match specifications. Budget-focused buyers may prefer Auto Battery Online despite the manual fitment process, while those requiring urgent roadside replacement benefit from Marshall’s 24-7 mobile service.
