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.
Short-trip drain
Lots of school-run / corner-shop driving never lets the alternator catch up. Common in suburbs like Subi, Como, Floreat.
Battery is genuinely dead
Even a jump won't hold — voltage drops the moment we disconnect. That's a replacement, and we have stock in the van.
Why people call us first
A jump start sounds simple — until you realise nobody you know carries cables, and the only car nearby is a Tesla. We carry purpose-built lithium jump packs that crank everything from a Hyundai i30 to a 200-series LandCruiser, with no risk of frying your ECU.
And before we leave, we test the battery on the spot. If it's healthy we'll explain what likely flattened it (lights, short trip, parasitic draw). If it's at end of life, you decide whether to replace it now or limp home and book it in.
What we bring on every job
- Lithium jump packs rated to 3,000+ peak amps (V8 cold-start)
- Voltage drop testing under load
- Alternator output check (rules out a charging fault)
- Full battery stock if replacement is needed on the spot

The service I received from Sami was top notch, very quick and efficient with good pricing.. I have no problems recommending the Sami and team for your next new battery requirements.
very happy with sami, very good to know even after hours he will be of service, 100% recommend
Family company, second hand battery for my commodore as new for a very good price. Lovely local family run business, will definately. Thanks Guys!
Very nice people here, no fuss. Thank you Sami
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!
Wonderful service
Frequently asked questions
Will a jump start fix the problem long-term?
Only if the battery is healthy and just got flat (lights left on, short trips). If the battery is at end of life, a jump start lasts hours, not days. We test on-site so you know which it is.
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.
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.
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.
