“Great service. Turned up at the agreed time to replace the Passat stop-start battery that Hollard Roadside Assistance that I called earlier that day didn’t have. All infotainment systems worked.”

Answering Your Questions About Our Stop-Start Batteries

What is a start-stop battery and how is it different?

Start-stop batteries are designed for modern vehicles and restart your engine every time your vehicle stops, like at traffic lights. They use EFB or AGM technology to handle frequent cycling and fast recharging, features that a standard battery can’t provide.

What’s the difference between a start-stop and a regular battery?

The difference between start-stop vs traditional batteries is that they’re built for high-cycle durability, frequent restarts, and rapid recharging. Standard batteries are not designed to handle this load and will fail prematurely in ISS vehicles.

How much does a start-stop battery cost in Australia?

Most EFB batteries start around $320, while AGM batteries can cost around $415, depending on the vehicle. The upfront cost of Start-Stop batteries is higher, but they generally last longer and support fuel-saving systems.

Do I need an AGM or EFB battery?

AGM batteries are suited to high-performance or luxury vehicles with advanced electronics or regenerative braking. EFB is ideal for standard stop-start systems.

Can I replace a stop-start battery with a regular one?

No, using a conventional battery in a stop-start vehicle can cause failure, poor fuel economy, and damage to electrical systems. Always replace with the correct EFB or AGM type.

How long do start-stop batteries last?

Typically 2–4 years, depending on driving habits, climate, and system demands. Short trips and frequent stops put more strain on the battery, making quality and proper fit essential.

Do start-stop batteries really save fuel?

Yes, start-stop systems are designed to reduce engine idling, which can lower fuel consumption by up to 8%, or even 26% in ideal conditions. That’s why many vehicles now include ISS (Idle Stop Start) tech by default.

How do I know if my stop-start battery is failing?

Common signs include the stop-start system not activating, warning lights, sluggish starting, or electronics behaving erratically. Marshall can test and replace your battery onsite.
