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.
We'll fit a battery you supply for a flat labour fee. We'll also test it before fitting to confirm it's not DOA.
VW, Audi, BMW, Mini, Mercedes — coded to the car with factory-grade diagnostic gear.
We bring extension leads to keep the car's memory alive during the swap. No re-set radios, no re-trained windows.
Fitting a modern car battery is not what it used to be. Most European cars need the new battery's serial registered to the car's energy-management module — without it the alternator under-charges and the new battery dies within a year. Most 4WDs need the right hold-down hardware. Most stop-start cars need an AGM, not a wet cell.
We do fitting as a standalone service if you've bought your own battery, or as part of a full supply-and-fit. Either way you get the proper torque on the terminals, the right hold-down, and a system test before we leave.
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
Yes — fitting-only is a standard service. We'll test the battery before fitting to make sure it's not faulty (it does happen with online buys). Call for the labour fee.
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.
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.
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.
Tap card, Apple/Google Pay, EFTPOS or cash — all handled on-site when the install is done. Tax invoice emailed within an hour. No deposits, no upfront payment.
