Start-Stop Battery Replacement

Start-stop engines shut down and restart at every set of lights, placing far more demand on the battery than conventional driving. Standard flooded batteries fail rapidly under this cycling. Start-stop vehicles require EFB or AGM batteries engineered for thousands of restart cycles — fitting the wrong type disables the start-stop function and dramatically shortens battery life.

EFB (Enhanced Flooded Battery) is designed for mild start-stop systems with moderate accessory loads. AGM (Absorbent Glass Mat) suits more demanding start-stop vehicles with heavy electronics and regenerative braking systems. Our technicians select the correct type for your specific vehicle and model year.

Yes. Most modern start-stop vehicles require the new battery to be registered to the battery management system (BMS) so it charges correctly and the start-stop function continues to operate. We carry professional diagnostic tools to perform BMS registration on the spot.

A start-stop warning light often means the system has deactivated itself to protect a weakening battery. This is usually an early sign the battery needs replacing. Our technicians test the battery and charging system on the spot to confirm the exact cause before recommending any action.

All EFB and AGM start-stop batteries we supply and fit are covered by a 2-year warranty. If the battery fails within this period, we'll return to your location and replace it at no charge.

Membership clubs charge an annual fee whether you use the service or not, and many apply a waiting period before a new membership becomes active. MS Road Assist works differently — there's no annual fee, no membership, and no waiting period. You call 1300 121 595 when you actually need help, get a clear price upfront, and only pay for that one callout. For drivers who rarely break down, this usually costs less over time than an annual membership; for drivers who call for help often, a membership may work out cheaper — it depends on how often you actually need roadside help.

No. MS Road Assist is fully independent — we don't process insurance claims on behalf of other providers, and we're not affiliated with any roadside membership club or competitor brand. You deal directly with us on a simple pay-as-you-go basis, with no third party involved.
