Choosing the right car battery for your vehicle might not sound like a straightforward process. With so many brands and types available, it can get overwhelming to compare all the options to choose from.
If you’re proactively planning a car battery replacement, this guide will walk you through how to find the right car battery for your vehicle, understand the different types available in the market, and what to consider before you replace your old battery. Our goal at Every Battery is to help you make a confident, informed decision without the guesswork.
How to Check What Battery You Should Buy for Your Car
One of the most common questions we get at Every Battery is, “What battery should I get for my car?” The answer depends on several factors, but it mainly depends on your vehicle’s make, model, and year, along with the manufacturer’s recommended battery specifications.
Modern vehicles are constantly changing and becoming more complicated, so it’s important to avoid picking an incompatible battery. That’s why we’ve built a registration tool to help you identify the car battery you need. All you need to do is search your car’s registration or the car brand, model, year, and engine type. In this article, we’ll also dive deep to understand what makes a good battery and the differences between the types of batteries available.
How to Identify A Good Car Battery
A good car battery should deliver reliable starting power, suit your vehicle’s electrical demands, and perform consistently over time.
There are several key indicators of a high-quality battery, including:
- Cold Cranking Amps (CCA): This measures how well a battery can start your car in cold conditions. However, you’ll need to ensure that the battery’s CCA rating matches the vehicle’s specific requirements.
- Build quality & brand reputation: Higher-quality batteries will typically last longer and perform better. You’ll find top brands such as Panasonic and Varta stocked in Every Battery stores.
- Warranty coverage: A solid warranty often reflects confidence in battery performance and its longevity.
Regular car battery testing is also essential to check your battery health. Testing can identify symptoms of declining performance early, helping you avoid unexpected breakdowns and extending your battery life.
Comparing Types of Car Batteries
Lead-Acid Battery
Lead-acid batteries are the most widely used car batteries in Australia. They use a liquid electrolyte and a proven chemical process to deliver reliable starting power for everyday vehicles. Lead-acid is the most popular battery type that’s used in petrol and diesel cars.
These batteries are typically found in:
- Older vehicles
- Cars without stop-start technology
- Vehicles with minimal electrical accessories
One of the biggest advantages of lead-acid batteries is their affordability. They offer dependable performance at a lower upfront cost, making them a popular choice.
However, lead-acid batteries are more prone to damage from common misuses, such as:
- Repeated short trips
- Extended periods of inactivity
- Deep discharging
Lead-acid batteries don’t handle frequent “partial recharge” driving patterns as well (i.e. repeated short trips), whereas stop-start rated batteries, such as Enhanced Flooded Battery (EFB) and Absorbed Glass Mat (AGM), are designed to suit these driving conditions.
EFB Battery
Enhanced Flooded Battery (EFB) is similar to a traditional lead-acid battery, but built with internal upgrades that make it far more resilient to repeated starting and recharging cycles. In practical terms, EFBs offer better charge acceptance and greater cycle resistance than lead-acid batteries, helping them meet the demands of frequent short trips.
You’ll commonly find EFB batteries in:
- Cars built with basic stop-start systems
- Cars with more accessories and higher day-to-day electrical load
- Hybrid and electric vehicles
While EFBs don’t have the same capabilities as AGM batteries, they offer more capability than conventional lead-acid batteries and are often more affordable than AGM batteries.
Note: Stop-start battery types aren’t always interchangeable. As a rule of thumb, don’t replace AGM batteries with EFB batteries. Our team of battery specialists can help you replace your car battery with the correct type that aligns with the manufacturer’s specifications.
AGM Battery
Absorbent Glass Mat batteries, also known as AGM, use an advanced battery technology specifically designed for newer vehicles that require higher and consistent power output.
Instead of using a liquid electrolyte, AGM batteries use fibreglass mats to absorb and hold the electrolyte, providing certain advantages, including:
- Faster recharge
- Greater vibration resistance
- Sealed and maintenance-free, preventing spills
AGM batteries are also commonly found in vehicles with:
- Stop-start systems
- Advanced safety features
- High accessory loads (i.e. screens, sensors, cameras)
- Smart charging systems
As these batteries are engineered to handle frequent starts and higher electrical loads, they can offer better performance and longer lifespans than lead-acid batteries if the car is well-maintained. However, they are considerably more expensive and must be matched correctly with the vehicle’s requirements.
Key Factors to Consider Before Replacing Your Car Battery
Battery Size and Physical Fit
One of the most important aspects is ensuring the battery physically fits your vehicle. Car batteries come in different sizes, and having even the smallest mismatch can cause:
- Vibration while driving
- Loose or stressed terminals
- Reduced battery lifespan
Checking your vehicle’s specifications, owner’s, or using a rego-based tool is the safest way to ensure you have the correct battery size and terminal placement.

Cold Cranking Amps (CCA) and Power Requirements
CCA ratings are important performance ratings, as it measures how much power the battery can deliver to start your engine. Even in Australia’s warmer climate, vehicles with larger engines, diesel motors, or higher electrical loads still require sufficient CCA to start reliably.
A good car battery design balances longevity in both hot and cold climates, with good starting power and strong reserve capacity to run the vehicle’s electronic computers and accessories. This requires stable voltage, overall capacity, and adequate starting power that needs to be balanced. Most after-market batteries focus on “CCA” for marketing reasons, to the detriment of these other critical requirements.
Reserve Capacity and Backup Power
Reserve Capacity refers ot how long a battery can continue supplying power if the alternator stops charging.
A higher reserve capacity can be beneficial if:
- You frequently use accessories while parked
- Your vehicle has an advanced electrical system
- You want extra peace of mind during unexpected situations
While the reserve capacity rating isn’t always the first thing people check, it plays an important role in overall battery reliability.
Maintenance Requirements
Car batteries generally fall into two maintenance categories: maintenance-free and low-maintenance batteries, and this is closely linked to the type of battery you choose.
All AGM batteries are maintenance-free, as they come sealed straight from the factory. This design ensures the electrolyte never needs to be topped up, making it a convenient option for modern vehicles and drivers who want a minimal maintenance routine.
Lead-acid batteries are typically low-maintenance. They contain liquid electrolyte and may require occasional checks and topping up with distilled water over their lifespan. While they are more affordable, they require a greater level of attention and care.
Understanding the maintenance requirements for each battery type can help you choose a battery type that’s suitable for both your vehicle and your preferences.
