I went to Repco today to pick up some oil + filter from the current deal and saw this at the check out counter.

30% off storewide including car battery, 1 day only sale this Sunday 10/7/16. It is the best time to buy your car battery especially in the winter cold weather. Usually if your battery is old or did not maintain it, you will get problem when the weather is cold. If your battery is dying now is the best time to buy.
I bought Repco battery last time and it lasted 3 years. Actually it should last longer but I neglected to maintain water level and it dried out. So if you bought car battery make sure you maintain water level with demineralised water especially in summer time and your battery will last much longer. All you need to do is check the water level and top it up, clean the build up and corrosion on the terminal.
For demineralised water, ironically it is cheapest to buy from Coles instead of the ripoff price from Repco or SupercheapAuto
