Won't take a jump
Most reliable sign of a dead battery — voltage drops the second the pack disconnects. Replacement, not jump.
Genuinely dead? We swap it on the spot.

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.
Battery's 4+ years old
Perth heat eats batteries. If yours is 4 years and showing any weakness, it's borrowed time. Replace before it strands you.
Bulging case or smell
Don't even try to jump it. Call us — we'll handle it safely and recycle the old one.
Why people call us first
Most Perth car batteries die at 3 to 5 years, earlier in cars that sit a lot or live outside in the summer sun. When they go, they usually go fast — fine on Friday, dead on Monday. By the time you're searching "dead car battery Perth" you usually need a new one, not a jump.
We test on-site to confirm it's actually dead (not just discharged), pick the correct fitment from the van and install in around 25 minutes. You drive away with a warranty card and a tax invoice in your inbox.
What we bring on every job
- Conductance tester — measures real battery health, not just voltage
- Full passenger battery range stocked
- Safe handling of swollen / leaking batteries
- Old battery taken away to certified recycler

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
How can you tell a battery is dead vs just flat?
We test it under load with a conductance tester. A flat battery shows good cold-cranking amps once charged; a dead one fails the CCA test no matter what voltage it reads. The test takes 30 seconds.
Can't you just jump start it instead of replacing the battery?
We can — but if a battery is at end-of-life a jump is a band-aid. We test the battery on the spot with a proper conductance tester. If it's just flat (lights left on, short trip drain) we'll jump and charge it. If it's dead, you decide whether to replace or wait.
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.
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.
