Battery replacement suggestions
Well, the battery just died in my 2005 SC430.
I'm certainly capable of doing an internet search for a reliable replacement, but thought I'd ask here if anyone has a preference based on experience.
Thanks for your thoughts.

If you have a costco battery in your car, it is usually cheaper to have them replace it at their pro-rated replacement cost.
If you don't, then I highly recommend an AGM battery. Though they came out after the SC430 was designed, they do better than a traditional battery because they handle vibrations and heat better.
I tend to stay away from the National Autopart stores to buy batteries. They always seem like they are 150% in cost.
Warehouse stores are usually great in price. I have bought car batteries from Homedepot and have been happy also. If you have AAA, they have a battery van that comes out and replaces the battery for you (at least in Arizona)

Thanks for the quick response. I love Costco but they don't have a store near me in this isolated part of Florida 
I'm definitely going with AGM. I'll check the SAM's club near me. That may be a good enough alternative to Costco.
Thanks again for your quick response..
You might remember me as the dude that can't spell your name

Read thread.
Long and short, you live in Florida. Heat kills the battery faster than anything else. AGM does not last enough longer to be worth 2 to 3 times price of lead acid. Get an inexpensive Walmart or Interstate Lead acid, replace it as needed when heat kills it. Lead acid cost about the same as two tanks of gas. Guys WAY overthink these expendables.

I live in Arizona. It is HOT! Frequently 120f/48c hot. Most lead acid batteries last 2 years here. In fact, Costco changed their battery policy here recently, no more 5 year guarantee. My AGM only costed $50 more and has lasted 4 years.

I have had great success with the Duracell AGM batteries. I got 6 years out the original one in my 2006 SC. I also have one in my 2010 LS 460L and my son has one in his 2005 SC 430. You can get them through battery plus stores I think they are group 24?

Canada Costco Battery warranty on Kirkland Batteries; Is 48 month full replacement, then prorated to 100 months. AGM is full replace to 60 months, prorated to 100. Our LSs are configured for lead acid, which have a diofferent charge profile than AGMs, so that is what I use in them. On top of that, the AGM batteries are significantly more expensive and they do not last enough longer than lead acid to justify the extra cost. Like I said before, the thing that kills batteries the fastest is high heat. It kills AGMs almost as fast as lead acid. It is why the battery warranties in the States are so much shorter than up here, they have to consider Texas, Arizona and Florida.

Experience is a wonderful thing
Here are my two options locally:
EverStart Plus Lead Acid Automotive Battery, Group Size H6 / LN3 / 48 12 Volt, 660 CCA - Walmart.com
EverStart Platinum AGM Automotive Battery, Group H6 / LN3 / 48 12 Volt, 760 CCA - Walmart.com
This is FL and it is HOT. I drive my SC430 pretty much everyday -- but most of the daily mileage is minimal. Also, I don't have a 3rd garage like many in my neighborhood, so the baby car has to live outside
