What to Look for in a Car Battery
When shopping for a replacement car battery in Australia, consider these key factors:
- Cold Cranking Amps (CCA) - Essential for reliable starting in all conditions
- Reserve Capacity - How long the battery can power your vehicle's electronics
- Warranty Period - Look for batteries with 24-48 month warranties
- Battery Type - Choose between standard MF, EFB for start-stop, or AGM for performance
Australian Climate Considerations
Australia's extreme temperatures can significantly impact battery performance. In hot climates like Queensland and Western Australia, batteries can degrade faster due to increased chemical activity. Our recommended batteries are specifically tested for Australian conditions and offer superior heat resistance.
Start-Stop Technology Batteries
Modern Australian vehicles increasingly feature start-stop technology for fuel efficiency. If your car has this feature, you'll need an EFB (Enhanced Flooded Battery) or AGM (Absorbent Glass Mat) battery. Standard batteries won't handle the frequent cycling required by start-stop systems.
