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.

Slow cranks lately

Classic marginal battery. We test and tell you whether to replace now or coast for a few months.

Battery 4+ years old

Perth heat eats batteries. If yours is 4+, test before summer to avoid being stranded.

Just want a second opinion

Mechanic said "battery is dying"? Happy to retest for an honest second read.

Why people call us first

A modern battery test isn't a voltmeter on the terminals. It's a conductance test that measures the battery's real cranking ability under load. We use Midtronics-grade testers and we can tell you within 30 seconds whether the battery is healthy, marginal or end-of-life.

We don't charge for the test. If we test it and recommend replacement, you decide whether to go ahead. If we test it and it's fine, no charge. We're confident enough in our testing that we don't need to upsell — most of our replace recommendations are accepted because they're genuinely warranted.

What we bring on every job

  • Midtronics MDX-650 conductance tester
  • Alternator output diagnostic
  • Honest read — replace, marginal or fine
  • Free if you don't replace

  • 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

Is the test really free if I don't replace?

Yes — we'd rather earn your trust than chase a small fee today. If we test and recommend a replacement and you decline, no charge. If we test and the battery is fine, also no charge.

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.

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.

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.

What if it's not the battery — alternator or starter?

Our techs carry full diagnostic gear. We test the battery, alternator output and starter draw on-site before we replace anything. If the battery is healthy and the alternator is the problem, we'll tell you straight up so you don't waste money on the wrong part.

Stuck right now? One phone call, one fixed price, sorted in 30 minutes.
