Staff were very helpful and accommodating to my stress. The price for the battery and fitting was $140 cheaper than Mazda fitting a none genuine battery. Will continue to visit and use Supercheap Melton.

I intentionally went to buy an Australian made Century battery, only to find this eas made in Korea. Oh well, still an Aus company I guess.

Battery was faulty. Would not start the car and had to get RACQ out. Bought a new battery through RACQ. RACQ tested it and it was deemed faulty. Took it back to the store and store did not refund. Said the battery was fine which it was not. Super Cheap Auto are not mechanics

Gentleman at the battery centre was so helpful and supplied me with the correct battery for my car and was very good at his job. The battery was $110.00 cheaper than Penrith Mazda.
Bought this battery recently as iStop stopped working on my car. I was informed by Mazda that it was due to an impending battery problem. So I shopped around for a good price, and found the battery going cheaper for Super Cheap members. I was a bit wary about how the car computer would react, as well as the iStop, but bit the bullet and purchased it. Fitting was no problem - although I was very quick lifting it with the built in handle and getting into place. Started and no iStop. But after a while of running all came good. Everything works. Major part was resetting the auto up/down on the driver's window (took 5 minutes to find it in the manual, 5 seconds to do it).
Researched for the best ISS battery for my CX5 and the Century Q85 seemed to keep coming up. Checked prices and Supercheap was the best price available in my area. I did a click and collect and received a text within the hour to say it was ready for pick up. Super easy and super cheap! Very happy with battery so far, car back to running perfect.
Worked as advertised in my Mazda cx 5 as a replacement for the 5 year old original battery. The flashing I-Stop warning on the the dash disappeared on first re-start and the I-Stop system working correctly immediately. Excellent value at the" On Special" price of $189.
Took time for SRA staff to install but all worked in the end. The iStop warning switched off immediately when it was installed! Recommended
Works. Cheaper than Mazda3 battery replacement. Had to youtube the Mazda reset procedure and istop reset.
Easy to install, worked perfectly on my Mazda istop with no glitches at all (unlike previous experience paying more for the battery and overpriced fitment) extremely happy with it
