ISS and hybrid car batteries are made for modern vehicles with advanced electrical systems, including stop/start technology and hybrid drivetrains. These systems put extra strain on a 12V battery, so ISS and hybrid batteries are built for durability, fast recharging and reliable performance. At Supercheap Auto, our range offers dependable starting power, steady electrical output and long-lasting life. You can trust a Century ISS or hybrid battery to deliver the reliability needed to keep stop/start and hybrid vehicles running smoothly.
Reliable power with ISS and hybrid batteries
ISS and hybrid batteries handle the extra demands of modern vehicles, providing strong starting power and stable electrical support. The enhanced construction manages frequent start/stop cycles and higher electrical loads that would wear out a standard battery. Fast recharge keeps the battery ready for use, while steady power supports electronics, safety systems and onboard modules. Built to meet or exceed manufacturer standards, ISS batteries and hybrid batteries deliver peace of mind for drivers of stop/start and hybrid cars.
Difference between ISS vs hybrid batteries
An ISS (idle-stop-start) battery is designed for petrol or diesel cars with stop/start systems. It handles frequent engine shutdowns at traffic lights and restarts automatically, so it must recharge quickly and cope with constant use. A hybrid battery is made for hybrid vehicles, powering electronics, safety features, lights and infotainment while the main high-voltage battery drives the motor. ISS batteries suit standard stop/start vehicles, while hybrid batteries are needed for models such as Toyota hybrids or Honda hybrids, as examples.
Understanding ISS and hybrid battery tech
At Supercheap Auto, our range includes different battery technologies to suit various vehicle systems. EFB (Enhanced Flooded Battery) is ideal for standard ISS vehicles, offering longer life and quicker recharge than a regular battery. AGM (Absorbent Glass Mat) provides higher performance for cars with heavier electrical loads or advanced stop/start systems. Hybrid-specific batteries support the 12V electronics in hybrid vehicles, working with the high-voltage battery to keep all systems running reliably.
How to choose an ISS or hybrid battery?
Choosing the right battery starts with knowing the vehicle and its electrical system. Stop/start cars need an ISS battery, while hybrid vehicles require a 12V hybrid auxiliary battery. Important considerations include size, capacity, technology (EFB, AGM or hybrid-specific) and system compatibility. When in doubt, always check the manufacturer’s recommendations to make sure the car battery meets your vehicle’s requirements. If you’re still unsure, simply enter your car rego into ‘My Garage’ to see which products are compatible with your specific vehicle.

Frequently Asked Questions - ISS & Hybrid Batteries
What is an ISS battery?
An ISS (Idle Stop-Start) battery is designed for cars with stop/start systems, where the engine automatically turns off at traffic lights and restarts when you press the accelerator. These batteries are built to handle frequent start/stop cycles, recharge quickly, and provide reliable starting power, unlike standard car batteries.
What is a hybrid car battery?
A hybrid battery in this context refers to the 12V auxiliary battery in a hybrid vehicle. It powers electronics, safety systems, lights and infotainment, while the main high-voltage battery drives the motor. A hybrid auxiliary battery ensures stable performance of all onboard systems and prevents warning lights or electrical issues.
Can I use a standard battery instead of an ISS or hybrid battery?
It is strongly recommended not to use a standard car battery in a stop/start or hybrid vehicle. Due to a standard battery's inability to quickly recharge, using a standard battery in an ISS or Hybrid vehicle can lead to poor performance, shorter battery life, warning lights, or electrical issues. ISS and hybrid batteries are specifically designed to handle the higher demands of these systems.
What are EFB and AGM batteries, and which one do I need?
EFB (Enhanced Flooded Battery) and AGM (Absorbent Glass Mat) are battery technologies used in ISS and hybrid batteries. EFB batteries are ideal for standard stop/start cars, offering better life and faster recharge than regular batteries. AGM batteries provide higher performance for vehicles with heavy electrical loads or advanced stop/start and hybrid systems. Selecting the right technology depends on your car’s system and manufacturer recommendations.
How do I know which ISS or hybrid battery fits my car?
The easiest way to find the right ISS or hybrid battery is to use Supercheap Auto’s ‘My Garage’ tool. Enter your car rego into ‘My Garage’ to see all the compatible ISS and hybrid batteries for your specific vehicle. It’s also important to double check the battery’s size, capacity and technology (EFB, AGM, or hybrid-specific) to ensure it matches your vehicle’s requirements.
