Start-stop
& AGM batteries
If your engine switches off at the lights, it needs a specialist battery. We fit the correct AGM or EFB battery and register it to your car’s computer, so start-stop and charging keep working properly.

About this service
Why start-stop batteries are different
Start-stop engines restart dozens of times on every trip, so they use EFB (enhanced flooded) or AGM (absorbent glass mat) batteries built for deep, repeated cycling. A standard battery fitted instead can fail within months.
Many cars also monitor battery age and adjust charging to suit. When a new battery is fitted, it needs to be registered with the car’s battery management system — otherwise it can be over- or under-charged.

FAQ
Start-Stop & AGM Batteries questions
What battery does a start-stop car need?
An EFB or AGM battery, depending on the system. Your car’s original battery type is the one to match — we confirm it from your rego.
Do new batteries need to be registered to the car?
Many modern cars, especially European models, need the new battery registered so the car charges it correctly. We do this on site.
Can I fit a normal battery to a start-stop car?
It’s not recommended — it will wear out quickly and start-stop may stop working.
