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.
Cranks but won't fire
Battery probably OK. We test it to confirm, then point you at fuel, ignition or starter as the likely culprit.
Dash lights flicker, then nothing
Classic dying battery or loose terminal. We check both — sometimes a clean and re-tighten is all it needs.
Why people call us first
When a car won't start there are really only four likely causes: flat battery, dead battery, faulty alternator, or starter motor problem. Three of them we can diagnose and confirm in your driveway in under 15 minutes — without removing a single bolt.
We bring conductance testers, voltage drop meters and crank-amp tools. You'll know exactly what's wrong before any money changes hands. If we can fix it here (battery 80% of the time), brilliant. If it needs a workshop, we'll tell you that too — no charge for the test.
What we bring on every job
- Midtronics MDX-650/series battery & system tester
- Voltage drop tester for starter and grounds
- Alternator output diagnostic (charging fault detection)
- Full passenger battery range in the van for same-trip replacement

Frequently asked questions
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.
What if it turns out to be the alternator?
We'll confirm it on-site and refer you to a trusted Perth auto-electrician. There's no charge for diagnosis when we don't replace the battery — we'd rather you trust us next time than oversell once.
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.
Do you actually answer the phone at 2am?
Yes — we're genuinely 24/7. Same number, same techs, same price. No surcharge for night, weekend or public holiday call-outs. If you're stranded, just call.
