What You'll Learn
Battery type: AGM, EFB, calcium, or STD
When choosing a car battery, it's important to select the right type for your vehicle. The three main types of car batteries available are AGM, EFB, and calcium batteries.
AGM Batteries
AGM stands for Absorbed Glass Mat. AGM batteries are designed to cope with the higher energy demands of modern cars and their accessories. They are ideal for cars with Stop-Start technology, which requires a battery with a higher output. AGM batteries produce higher amp power output for the same size as a calcium battery and are better suited to modern car charging systems. They are also safer to install in passenger compartments as they are sealed and don't produce harmful fumes or gases. AGM batteries are more expensive than calcium or EFB batteries, but they last longer and require less maintenance.
EFB Batteries
EFB stands for Enhanced Flooded Battery. These batteries are designed for cars with Stop-Start technology and are considered entry-level for this use. They are similar to standard flooded batteries but have enhanced cycling abilities and improved charge acceptance. EFB batteries are positioned in the middle of the battery hierarchy and are more affordable than AGM batteries.
Calcium Batteries
Calcium batteries are the most common type of car battery and are positioned at the base of the battery hierarchy. They are lead-acid batteries with small amounts of calcium added to the plates to improve durability and reduce water consumption. Calcium batteries offer improved resistance to corrosion, no excessive gassing, and reduced water usage. They are well-suited to extreme Australian weather conditions and can withstand higher charge rates.
STD Batteries
The Standard Flooded Lead Acid (STD) battery is the most basic type of car battery. It is less advanced than AGM batteries and may not offer the same reliability or durability in harsh Australian conditions.
It is important to choose the right type of battery for your vehicle, taking into account factors such as technology, performance, and climate. Additionally, ensure that the battery fits the dimensions of your car's battery tray and that the terminals are compatible.

Battery size: Width, length, and height
When choosing a car battery, it is important to select one that fits the battery tray. The battery must align with the cable connections and have terminals that fit correctly. The battery's width, length, and height are critical factors in ensuring it fits perfectly and does not shift in its slot. A battery that does not fit properly can lead to short-circuiting, leaks, and damage to the car's electrical system.
Battery group sizes, established by the Battery Council International (BCI), provide standard dimensions to ensure compatibility. These group sizes indicate the physical dimensions of the battery, including length, width, and height, allowing for easy replacement. For example, Group 51R batteries are suitable for smaller cars with compact battery compartments, while Group 65 batteries are recommended for larger vehicles with higher electrical demands.
When replacing a car battery, it is essential to match the dimensions of the new battery with the battery tray and engine compartment size. This ensures a perfect fit and prevents any movement that could cause electrical issues. By consulting battery size charts, you can identify the appropriate group size for your vehicle and select a battery that aligns with the cable connections and terminal layout.
Additionally, it is worth noting that some batteries may have different terminal placements, such as top or side posts, which should align with the corresponding connections in your vehicle. The compatibility of the battery's dimensions and terminal placement is crucial to ensure a safe and functional electrical system in your car.

CCA and RC ratings
CCA, or Cold Cranking Amps, measures a battery's ability to start an engine in cold climates. It indicates the number of amps a 12-volt battery can deliver for 30 seconds at a very cold temperature (ranging from -17.8°C to -18°C) before the voltage drops to an unusable level, becoming too low to start the engine. The CCA rating is usually displayed on the battery label and can range from 100 to 850 or higher, depending on the vehicle type. A higher CCA rating generally indicates a longer-lasting battery, but this is not as important a consideration in high-heat climates like Australia.
RC, or Reserve Capacity, refers to the number of minutes a car battery can maintain a current draw of 25 amperes before its voltage falls below 10.5 volts. This test is performed at a temperature of 25°C. A higher RC rating is better, as it indicates a longer reserve capacity. RC is particularly important if you live in a cold climate, as it helps to power your vehicle's electrical system if the alternator fails.

Climate and temperature
When choosing a car battery in Australia, it is important to consider the climate and temperature. Car batteries need extra care in extreme cold and hot temperatures. In Australia, the summer heat is tougher on car batteries than the winter chill. High temperatures can speed up the corrosion of your car battery and affect the power-generating chemistry inside. This can lead to unexpected failures and roadside breakdowns.
To ensure your car battery can withstand temperature fluctuations, consider the Cold Cranking Amps (CCA) rating, which measures how well a battery can start your engine in cold weather. CCA is the amount of energy needed to start your car on chilly 0°C mornings. Higher CCA ratings mean better performance in colder temperatures, so if you live in a cold climate, prioritise this specification. The CCA of your battery should meet the minimum rating recommended by your manufacturer, with smaller cars requiring around 150 CCA and high-performance vehicles needing closer to 500 CCA.
In hot weather, the internal electrical resistance of a car battery decreases, and the battery's capacity goes down. As a result, the battery may not have enough power to start the engine. For hot weather conditions, consider the hot cranking amperes (HCA) rating if it is displayed. HCA is a rating specifically designed for warm conditions, indicating the available power from the battery as the temperature increases. AGM batteries, which are standard in modern cars with stop-start systems, perform well in the heat but may have reduced lifespans in high temperatures. Traditional flooded batteries can be replenished with distilled water to extend their lifespan in hot climates, but AGM batteries are sealed and cannot be topped up.
To maintain your car battery in extreme temperatures, consider purchasing battery insulation blankets to protect against heat and cold. Regularly inspect your battery, especially before and after winter, to ensure it can handle temperature changes. Additionally, park your car in a garage during cold weather to shield it from extreme temperatures and reduce strain when starting the engine.
