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.

Stop-start has stopped working

9 times out of 10 it's a tired battery. We test, confirm, fit a fresh AGM and re-enable the function.

Battery warning light on

Often a stop-start fault code. We can diagnose on-site.

Car cranks slow

AGM degrading. Replace before it strands you — same convenience, much better outcome.

Why people call us first

Modern stop-start cars switch the engine off at every red light. That's brutal on batteries — far more cycles than a non-stop-start car. The factory-fit AGM or EFB typically lasts 4–6 years; replacements need to match the original spec, or stop-start refuses to engage.

We carry the stop-start AGM range, register the new battery to the car's energy-management module, and confirm the auto-stop function is restored before we leave. Most cars don't need any other intervention — battery + coding + drive = sorted.

What we bring on every job

  • Stop-start AGM / EFB stock
  • BMS registration tools
  • Stop-start function reset / re-enable
  • On-site testing before leaving

  • Had the unpleasant task of being stuck with a flat (also dead and gone) battery today and made a call to Car Battery Perth 24/7. They were absolutely brilliant, got to me within 15 minutes and barely 5 minutes later had completed all scans and the battery replacement. Very fair pricing and only charged me for the battery, nothing else. Would absolutely recommend!

Frequently asked questions

Why does my new battery need to be registered?

Modern energy-management systems track battery age and charging cycles. Without registering the new battery, the system thinks the old battery is still in there and under-charges the new one. We register on every install where it's required.

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.
