I just installed a New Battery in my 2011 Genesis this Afternoon.....

I always replace my Car Batteries after 4 years. Best auto maint decision that I ever made over 25 years ago. I have never been Stalled or inconvenienced. I used to wait until it died and it was below zero and there were 20 other people in line to get a battery. This is the no-hassle way!

Battery swap was easy, but looking at all of the connections was a bit intimidating at first. The nice thing was that the old battery came out Showroom new and not full of dirt and grease like the ones under the hood! Hardest part was getting the bolt started in the clamp that holds down the new battery. This took me 15 minutes of screwing around and cursing. The whole job took me less than 1/2 hour. All of my settings remained on my Navigation System and Radio. Not sure how they accomplish this, as my Lexuses used to lose all these settings on a Battery Swap. Maybe they have a small battery like the Motherboard on a computer??

Sears had the correct battery at a good price.

A few 'Issues' with this Battery.

1.) It's not an AGM battery(Which I installed), so it's an Apples to Orange Comparison. Sears also has these Batteries for a much cheaper price.
2.) Cold Cranking Amps of this battery is 760 while the one I bought is 850.
3.) I would never buy anything at Walmart for many reasons. But that is my personal choice.

Or may be a capacitor to temporarily hold the charge? In either way it is smart.

Due to a cranky trunk switch and a wife that doesn't slam the trunk like she slams the doors I have had two completely flat batteries on my '12 R-spec over the past two months. The last one was dead for more than four days before I found it. Both times everything was back to jake once the battery was charged. Radio, nav, everything.

That depends on where you are.

I agree that an AGM (absorbed glass matt) style battery makes more sense for folks who have polar bears for neighbors. Folks in alligator country don't need AGM's freeze resistance, nor the higher CCA rating. What is more desired are thicker cell walls for greater heat resistance that warm climate battery variants offer (albeit almost entirely mitigated by the Genny's trunk mount).
