Hey guys my battery is stuffed and I need to purchase a new one just wondering if anyone could give me advice on a type of car battery or a specific store to purchase one, thanks

No doubt everyone wlil have a personal opinion but given the cost I always go the longest wty.

Exide Extreme
EXIDE have a 42 month wty at KTAS. I like the no fuss wty , had one replaced under wty recently after 2 years because the casing cracked around one of the posts and was leaking acid. Replaced, always keep the receipts.

Nationwide warranty against faulty materials and workmanship when returned to Kmart Tyre & Auto Service.

Supercharge batteries would be my choice and recommendation. Been getting 5 years + using their "silver" range. Brisbane warehouse allows direct purchases..not sure about nsw.

I run a Supercharge GoldPlus 75D23R myself. I'm real happy with it!

If you want a real good battery then buy an Australian made Century Yuasa lead calcium battery.
It comes with a premium price as well.

My advice on choosing a battery is here ...

The Century 75D23R is a very good quality, Australian made battery with a three year warranty, and is not "maintenance free" - so you can top up the cells with distilled water as required.

It can be found cheaper than many cheap and nasty batteries, such as here...

Places in QLD will hopefully price match for you.

Excellent cheers guys

There are different types of maintenance free (sealed) car batteries.

One battery type I would not use is the Absorbed Glass Matt (AGM) type.
These give excellent CCA (Cold Cranking Amps), are compact and robust (kind of ideal for cars!).
Except they are also low in AH (Amp Hour Capacity) because its a "starved electrolyte" battery.
The lower AH also relates to a reduced RC (Reserve Capacity).
If you over charge these batteries (for whatever reason!) then the electrolyte is quickly depleted by gas venting.
And you end up with a dry - dead battery.
If you over discharge then you end up with water for electrolyte - making it harder to recharge.

Given the abuse people throw at car batteries, these batteries often suffer from premature failure (its not the fault of the technology!).

Ideal choice is to find a "maintenance free" battery that still has plugs for topping up the electrolyte with distilled water.
These typically use lead calcium plates for their lower gassing characteristics and are of the flooded electrolyte type.
Flooded electrolyte batteries will release full plate capacity without the electrolyte turning into water.
These batteries have plenty of RC and tend to be heavier and bigger.

Never top up batteries with tap water as chlorine acts catalytically to accelerate positive plate corrosion.
