I've used many Supercharge Gold starter batteries and got a very good run out of them.
I always work on a battery is only as good as the warranty the manufacturer is prepared to put up.
1 yr warranty gets you the cheap and nasty batteries, 2 yrs is the average warranty, 3 yrs is the warranty provided on the better batteries - and the Supercharge Gold has a 4 yr warranty, which gets me in.
I've only had one Supercharge Gold fail within the warranty period - it failed at 3 yrs and 9mths.
Supercharge cheerfully replaced it with a new one - but the warranty is Pro Rata - so I only got 3 mths warranty on the new one.
That battery was still in the car, and still performing
well, when I sold it, 4 yrs later.
I've used Exide Extreme (4 yr warranty at the time - now reduced to 2 yrs). Both the Exide Extremes just made a whisker over 4 yrs. I don't think they're as good as Supercharge Gold Batteries.
I've only ever owned 2 Yuasa batteries. Both were genuine Japan-built Yuasa's. One went for 10 yrs and 4 mths! I was staggered, it just wouldn't give up!
The second Yuasa went for 8 yrs. I find that trying to source Yuasa batteries is a real hassle. No-one wants to stock them.
I also suspect that the Yuasa batteries you get today are no longer made in Japan. If I could buy another Japanese-built Yuasa, I'd be onto it, in a flash.
Re the Cat batteries. As a buyer and user of many Cat batteries over more than 4 decades, you will find that Cat batteries are built to withstand heavy vibration.
The "run-of-the-mill" batteries have little by way of support for the bottom of the plates.
Cat batteries have every plate heavily bonded to the bottom of the cell.
Cat found that heavy vibration cracked the plates in "run-of-the-mill" batteries, because they were unsupported at the bottom, and this allowed the plates to constantly flex back and
forth, eventually causing them to crack.
Cat batteries also have more clearance between the bottom of the cells and the bottom of the plates. This allows for more lead sulphate
debris (from decomposition of the plates) to build up.
The build of lead sulphate
debris in the bottom of the cells eventually reaches the bottom of the plates and causes a shorted cell. A cell with more clearance between the bottom of the plates and the bottom of the cell has a lower chance of developing a shorted cell.
Finally, I believe the answer to extended lead-acid battery life is using an electronic battery desulfator, that breaks up the lead sulphate crystals that shorten battery life.
I use an Infinitum desulfator, I've had it for about 8 or 9 yrs and I've saved many batteries from going to scrap, and extended the life of many others.
My favourite trick for cheap batteries, when I need a cheap one for something, is going down to "Bombs Away" car scrappers, and digging out a reasonable-looking battery from a scrapped car, that is still holding over about 12.4V (I take my multimeter and just simply
test the voltage, as it sits on the rack).
I select one showing more than 12.4V, and take it back to the workshop and slow trickle charge it over a couple of days with the desulfator attached - and 9 times out of 10, I end with a battery that returns at least 2 more years of satisfactory life - usually for around $35.
Cheers, Ron.

I was told by a local in Mackay there use to be a fellow yrs ago that made his own batteries in town and they lasted a very long time which put the big brands to shame. Something the industry doesn't like the little guy eating into their profit margins.
