Wherever you're stuck, we'll come to you
We do roughly half our work in driveways, a third in office and business-park carparks, and the rest on roadsides and in shopping centres across the Perth metro.
European luxury
BMW, Audi, Mercedes, Mini, Volvo — high-spec AGM, factory coded on-site.
Heavy-duty 4WD
AGM main with deep-cycle aux is a great combo for touring rigs.
Why people call us first
AGM batteries are the only safe choice for stop-start vehicles, most European cars, and any car with serious in-cabin electrical load. The wrong choice here is expensive — fit a wet-cell to a stop-start car and within six months the battery is shot and the stop-start function is disabled.
We carry the full OEM AGM range and we register every install to the car's BMS where required. Pricing is competitive — usually a long way under the franchise battery shops on the same brand.
What we bring on every job
- Genuine AGM (not EFB rebranded)
- BMS registration via factory tools
- Memory savers for codes/settings
- Old AGM removed and recycled

Frequently asked questions
What's the difference between AGM and EFB?
Both are designed for stop-start. AGM is the higher spec — better cycle life, deeper discharge tolerance, more expensive. EFB is a lower-cost stop-start battery suitable for entry-level stop-start cars. We fit whichever your car requires per the manufacturer.
Will you do my car? It's a [European / 4WD / hybrid / stop-start]
Yes — we replace batteries on every passenger vehicle on Perth roads: Japanese, European, American, Korean, 4WDs, utes, vans, hybrids, AGM stop-start cars, even classic vehicles. Coding/registration for BMS-equipped European cars is included.
What warranty comes with the new battery?
All standard batteries come with a 3-year nationwide warranty. AGM and stop-start batteries are 3–4 years depending on brand. The warranty is honoured at any Century / SuperCharge stockist Australia-wide, not just by us.
How much does mobile battery replacement cost?
It depends on your car's exact battery spec. Standard passenger car batteries are our most affordable option, supplied and fitted on-site; AGM and stop-start batteries cost more depending on spec. There's no call-out fee and no extra charge for after-hours, weekends or public holidays. We quote on the phone before we head out — call us with your rego for an exact price.
How fast can you actually get to me in Perth?
Average response is 30 minutes anywhere in the Perth metro, day or night. CBD and inner-suburb call-outs are usually 15–20 minutes. Outer metro (Mandurah, Two Rocks, hills suburbs) can be 45 minutes — we'll give you a real ETA when you call, not a guess.
